As stated in the regulations, it should be changed every forty-five thousand kilometers, and before that, it is advisable to warm up the car or drive it so that it does not become completely cold and is sufficiently liquid. To make the change you need the following set of tools:

Why is the Jimny such a special car?

A good car, the price of which will clearly exceed $000 in the USA. His name is Suzuki Jimny. Its attack angle is 34º and its exit angle is 31º. It impresses with a much larger ventral angle of at least 46 degrees, which has no problem negotiating huge slopes or moving between rocks. You mentioned that your front and rear axles are rigid?

Aesthetically, it is a correct car with an almost exotic touch and a design that has not gone out of style. However, not everything is pink: as we mentioned earlier, this is a very small car, it has four seats and its 113 liters of luggage is a joke. Despite everything, it is worth remembering its very competitive price. This is the ideal car that turns into a high-caliber SUV, or one that is specified for fleets. The rest of the trim adds convenience, but you'll never be able to equip air conditioning, cruise control or satnav.

Adjusting the backstage of the Niva Chevrolet

Removing the gearbox from a Chevrolet Niva

Based on all that has been said, the gearbox and transfer case are important elements of the Chevrolet Niva, without which it is impossible to engage gears. And a few words about the transfer case rocker The transfer case rocker performs similar functions to a boxed product, only the speed mode shift lever is not used as often as the transmission.

Having opened the hood of the Chevrolet Niva, you need to find the connection between the tip of the lever and the gear shift rod. Removing the gearbox linkage You can remove the linkage in the following sequence:

An old element of the transmission system, Niva Chevrolet backstage repair its service life In the event that the speeds begin to turn on very slowly or the speed that should turn on is not turned on, then you can try to adjust the mechanism. This question came to the mind of every Niva car owner who had to deal with a malfunction of this element. Replacement is made if there is play in the hinges or severe wear of the hole for the gearshift handle axis.

In fact, there is nothing difficult in choosing a component.

Poll Can you replace the rocker in your car yourself? Yes, I don’t see anything complicated about it No, I can’t do this labor-intensive process Thanks to these instructions, I’ll replace the slide myself Loading However, there is also a negative side.

In addition, despite Italian quality, these components of the transmission system are more susceptible to wear and tear.

If you have replaced the drive, but when driving you feel how the vibration of the gearbox lever remains, then, most likely, there is increased play in the lever hinge mechanism. Finding it is not difficult if you know what a gearbox is.

Gearbox control mechanism VAZ 2123 / rocker / 2123-1703050

The slide is located near the transmission shift lever and has the appearance shown in the photo below. Photo of a rocker located in the vehicle interior On older models of vehicles from the Russian automobile industry, the location of the rocker was under the bottom of the car, but this, first of all, reduced the service life of the product, which affected efficiency.

Parts and consumables:

Adjusting the rocker The rocker on Chevrolet Niva SUVs has a long service life, equal to over a thousand. But this resource depends, first of all, on the integrity of driving, so sometimes drivers may notice malfunctions in the gearbox, such as: When trying to engage first gear, it switches to reverse ; Fifth speed disappears when it is turned on; Reverse gear is engaged when forward five gears are selected.

This indicates a malfunction of the drive rod, but you should not rush to remove the gearbox and repair it, as you can try to adjust the product. Although adjustment is a rather difficult task, it is easier and cheaper than replacing a box or a link.

The gearbox engages first gear. To turn it on, you can start the engine and move the gearbox lever until the car starts moving.

Afterwards, the engine is turned off, the first gear remains on, and shoes are placed under the wheels. Don't forget the handbrake. To turn it on, you can start the engine and move the gearbox lever until the car starts moving.

Chevrolet Niva (2009+). Gears are difficult to engage

Reasons for difficulty shifting gears


The selection cable or gear shift cable is faulty (broken, torn, stuck in the sheath)	Replace the faulty cable
The gearbox control mechanism is worn or damaged	Replace mechanism
Worn or damaged gear shift mechanism	Repair or replace transmission
Worn gear synchronizers	Repair or replace transmission

- Clutch malfunction. In this situation, the gears will engage either poorly or not completely.

- Problems in the drive of the switching mechanism. Broken traction leads to difficult engagement of 1st and reverse gears. -Jet thrust is faulty. -Wear of plastic parts in the box control drive. -The slide is set incorrectly. A weighty element, incorrect adjustment leads to malfunctions. - Wear of bearings. This is a fairly rare occurrence; anyone can experience this, especially when you have a manual transmission. In such a situation, it is usually difficult to engage first gear. -The box shaft is faulty. By itself, it is not subject to heavy loads, which could lead to wear. A factory defect may cause the entire unit to be replaced. -Failure of clutches. Often found among owners of cars with an automatic transmission. The malfunction is eliminated by replacing the clutches. -Failure of synchronizers - the problem most often occurs among gearbox breakdowns. They are made of brass, and this metal itself is quite soft. During use, it wears out and wears out. —-

-The breakdown is usually accompanied by a grinding noise when switching to another speed.

Manual transmission (gears are difficult to engage)

There are also several clutch malfunctions that cause manual transmission gears to shift poorly:

- Airing of the clutch release hydraulic drive or leakage of fluid from it. The malfunction is eliminated by replacing failed components of the hydraulic system and pumping it. - Worn or broken clutch release fork. The part requires replacement or repair. - Warping (runout more than 0.5 mm) or the thickness of the new driven disk is too large. -Failure of the basket (temperature deformation of the pressure plate or its distortion). -Loss of mobility of the support bearing of the gearbox input shaft (at the end of the crankshaft to which the flywheel is attached). - Jamming of the clutch driven disc hub on the splines of the gearbox input shaft. To eliminate the defect, clean the splines of the gearbox hub and input shaft. It wouldn’t hurt to lubricate them a little with lithol. -Too much free play of the clutch release fork. Its value needs to be clarified with the manufacturer, since it is slightly different for different cars. Until you find out the value of this parameter for your car, set it from 5 to 8 mm. Too little free play of the fork is also undesirable, as it leads to clutch slipping and increased wear of the release bearing. -Excessive wear of synchronizers mainly occurs in those gears that are engaged more often: these are usually first, second and third. The rear one is not included in this list because it does not have a synchronizer. When your gear shifts poorly, and you assume that the reason for this is wear of the synchronizers, firstly, you should only have difficulties with this while driving. Secondly, in this case it switches better if you use double squeeze.

(What is a double squeeze. To shift into an upshift: squeeze the clutch, put it in neutral, release and squeeze the clutch again, shift into gear)

To switch to a lower gear: double squeezing must be combined with re-engaging, that is, when the clutch pedal is released and the gearbox is in neutral, you need to press and release the accelerator pedal. This is how gears are changed in cars that do not have synchronizers. If the gearbox shifts easier using double squeezing, then the culprit for poor gear shifting is most likely worn synchronizers.

A malfunction in the vehicle's clutch mechanism can also cause poor gear engagement:

- the tightness of the hydraulic clutch circuit is broken. As a result, when you press the clutch pedal, the required pressure is not created in the hydraulic circuit. Accordingly, the clutch disc is not released completely, which does not allow the required gear to be engaged. Leakage points are eliminated by replacing the rubber seals or by additional tightening the connecting nuts of the hydraulic circuit. - fracture or wear of the clutch release fork. The problem is solved by replacing the plug. If it is not possible to replace the part with a new one, the old fork is restored. - runout of the clutch driven disc (more than 0.5mm) as a result of overheating or manufacturing defects. - breakage of the clutch basket spring petals or their deformation as a result of overheating (manual transmission gears are difficult to engage); - failure of the manual transmission input shaft bearing. Eliminated by replacing the bearing. - the stroke of the clutch release fork is not adjusted; the cable connecting the clutch pedal to the fork has broken.

Another reason for unclear gear shifting may be a malfunction of parts and mechanisms in the gearbox:

- wear of synchronizers. Excessive wear of synchronizers occurs in those gears that are engaged more often, namely in the urban cycle these are first, second and third gears.

- manual transmission shaft bearings. The breakdown occurs mainly on cars with very high mileage or on cars that, by the nature of their activity, transport heavy loads. In both cases, manual transmission bearings are subject to increased wear. At the initial stage, bearing wear is manifested by the appearance of a monotonous howling sound from the box. If no measures are taken, then a wear appears in the worn bearing, which leads to axial runout of the bearing, followed by jamming. Parts of a loose bearing can get into the gears of the manual transmission and completely damage it.

-destruction of gearbox gear teeth due to physical wear or manufacturing defects. When operating a vehicle with a manual transmission, the teeth of one of the gearbox gears may “fall out” with subsequent possible destruction of the gearbox.

Automatic transmission (gears are difficult to engage)

An automatic transmission is much more demanding in terms of accuracy in maintaining the oil level in it than a manual transmission. Both too low and too high oil levels are very harmful to her. Both of these can lead to serious damage. In both cases, oil foaming occurs. When there is a lack of oil due to the fact that the oil pump begins to capture air along with the oil. When there is excess oil, it foams on the rotating parts, which in this case are immersed in it. Foamed oil compresses better and has low thermal conductivity. Therefore, if you operate a machine with such oil, the pressure in its control systems will be low. Which will lead to slipping of the clutches and their intensive wear. Deteriorated thermal conductivity will not allow all excess heat to be removed. Which, together with low pressure, will lead to the machine failing and requiring serious repairs.

The design of the rocker and its purpose on the Niva Chevrolet

In technical language, the word “link” means the gearbox drive rod. This is a complex mechanism and is designed to connect the gearshift lever in the cabin and the rod of the gearbox itself. In the interior of the Niva Chevrolet there is a backstage located near the gearshift lever, and therefore it is quite easy to find it.

Reverse gear is difficult to engage

On modern domestic SUVs, which is the Chevrolet Niva, the rocker life is quite large. It has to be changed on average after 100,000 kilometers. But the resource can be greater. It all depends on the accuracy of the driver and the operating conditions of the vehicle.

If the rocker fails, the driver will notice the following:

It is impossible to engage first or reverse gear.
The fifth speed may disappear when turned on.
Reverse gear is engaged if the driver wants to engage one of the front ones.

The presence of such moments indicates that the backstage is out of order. It is recommended not to rush to remove the gearbox itself and carry out repairs. This may simply require adjustment of the rocker itself. Despite the fact that such a task is quite troublesome, it is less expensive than repairing or replacing the entire gearbox.

After such actions, the work of adjusting the scenes can be considered completed. All that remains is to test it in action. When such measures do not bring the required result, the product will need to be removed and repaired.

Reverse gear slips out

If, after adjusting the rocker, the driver observes other malfunctions, for example:

problem with engaging reverse gear,
lever stroke increased,
reverse gear goes out,
speeds turn on noisy and tight,

then the backstage will need to be replaced.

conclusions

Knowing the moments and reasons why reverse gear does not engage in a Niva Chevrolet car, you can independently adjust the backstage without turning to specialists for help . If such a task seems difficult, you can always call a specialist for help or visit a service station.

How to remove the gearbox on a Chevrolet Niva yourself. Video

Begin:

Remove the ground from the battery (using the “10” key).
Then unscrew the bolt securing the starter from above (using a “13” wrench).

After this, you begin to work inside the car:

Remove the handles from the transfer case levers by turning them and pulling them up.
The casing of the boxes (both transfer case and gearbox) must be removed. To do this you will have to remove six screws.
By turning the casing, it can be removed.
Remove the housing and boot from the transfer case lever (removing the three screws).
Remove the connectors from the blocking sensor. Do not pull on the wire itself so as not to tear it off.
The cover on the slide can be removed by unscrewing two self-tapping screws.
Then engage reverse gear. To remove the lever itself, you will have to hook the locking sleeve with a screwdriver. When removing plastic and rubber parts of the lever, do not break the collet.

The main stage of work is directly removing the box. Watch the video - removing the gearbox on a Chevrolet Niva. If protection is installed under the crankcase, it must be removed. This also applies to the soundproof casing.

It is advisable to mark the flanges of the shafts and boxes. This will allow the parts to be positioned correctly during installation.
The bolt on the flange may be tight. Then you can help with a chisel, which is inserted between the flange and the bolt itself. A couple of hits should be enough.
Disconnect the rear propeller shaft from the transfer case. Stuck flanges are “treated” again with a chisel.
Remove the front driveshaft.
Disconnect the speedometer cable. When removing the oil deflector washer, be careful. Move the cable to the side.
If the car has a speed sensor, its connector must be disconnected.
Then unscrew the fastening of the elastic coupling onto the flange of the input shaft of the box.
The bolts are pulled out when the flange is in a strictly defined position.
To remove the transfer case, unscrew the four nuts (using a 13mm wrench).
After removing the cotter pin, remove the spring and fasteners on the clutch cylinder.
Move the starter closer to the radiator, after loosening its fasteners.
Remove the bolt holding the clamp from the muffler pipe. For greater convenience, you may also have to remove the muffler bracket (with the same “13” key).
Loosen the bolts on the gearbox housing (using a 10mm wrench) and the nuts on the traverses.
The box is attached to the engine with 19mm bolts. There is no need to remove the bottom bolt on the left completely yet, just loosen it. The rest will have to be removed using an extension cord. Now remove all bolts.
Carefully remove the box and disconnect it from the motor. Already holding it in your hands, move it back, right up to the stop of the scenes. The box should not be left hanging on the shaft.

Installation is carried out in reverse order.

[email protected]: why does the reverse gear slip out on a Chevrolet Niva?

So, about the most important thing:

Niva. The unscrewed nut of the “helicopter” shank or how not to repair cars.

And after work, without unnecessary fanaticism, we think: “Why is it constantly unscrewing?! The craftsmen advised me to look at the rocker from the beginning, perhaps the clamp is not tightened enough - I took the manual to read how to adjust the rocker, in which they write:

Read more about why the Chevrolet Niva does not engage reverse gear. The reverse gear falls out. 2…

This is a complex mechanism and is designed to connect the gearshift lever in the cabin and the rod of the gearbox itself. Now I'm wondering what could be the reason.

This may simply require adjustment of the rocker itself. When the speed is turned on, they are lubricated by splashing oil in the box. The whole procedure took 15 minutes with a photo session of the clamp.

I got to the shitty place, they hit the gas and jerked off, and took off. Then there was no need for much gas, it began to take off quickly.

VAZ 2101-07 Niva transmissions fly out

My mistake was that I spared effort on the nut. I returned to the garage, threw off the transfer case, hanging it on the cardans, screwed on a new nut, and let’s tighten it. I tightened it, putting the box in first gear, tightened the nut with a purchased 30 wrench, lengthening it with a pipe, until the box turned along with the motor.

Then he fixed the helicopter, resting it on the same pipe, and tried to pull it up with his hands, but it couldn’t be pulled any more. I collected everything, left the garage, immediately accelerated vigorously in first place and immediately took off, the dog. I don’t even know what to think.

The mechanism for engaging the rear is provided by lowering the locking stop to a position below the locking pad.

When the speed is turned on, they are lubricated by splashing oil in the box. To avoid oil leakage from the gearbox from the primary and secondary shafts, these places are sealed with oil seals, which periodically require replacement.

The exception is the inclusion of rear and fifth speeds, but on rear- and all-wheel drive vehicles of the VAZ family this order is always the same. So, let's look at the location of all the gears in the box and how they are engaged. If the rocker fails, the driver will notice the following: It is impossible to engage first or reverse gear.

The fifth speed may disappear when turned on. Reverse gear is engaged if the driver wants to engage one of the front ones. The presence of such moments indicates that the backstage is out of order. It is recommended not to rush to remove the gearbox itself and carry out repairs.

The main mistake was not the first one, which I did not take into account: Before loosening the clamp, you need to catch the neutral with the lever, and then loosen it - adjust and tighten it! So, about the most important thing: Road construction work is being carried out, well, almost throughout the city. I was the first to trudge to work. I decided to take a shortcut through a narrow yard, and there I would meet another driver like him.

Well, I’m in the back, but she’s not there. Without nerves, in third gear and only forward to the curb, I’m in a jeep.

In what case is replacement performed?

The gearbox is simpler than the engine, but sometimes it needs replacement. Often wear and damage force the car owner to buy expensive spare parts. Ultimately, the sum equals a used box in good condition. In this case it is better to change. Thus, a used box will be the best option.

In addition, replacement may be required after severe impacts and destruction of both the gearbox housing and internal mechanisms, which “dragged” along the parts of the fastenings to the housing. The price of a new Niva box is not high. Thus, repairs will cost the car owner less than many analogues.

How to replace the secondary shaft oil seal

If the secondary shaft of the gearbox has a leaky seal, this can lead to a decrease in the oil level. In order to carry out replacement repairs, you need:

Hammer
Various regular screwdrivers
Any key for thirty

And so to replace we go through the following steps:

Removing the intermediate transmission shaft
Remove the seal from the centering ring, unscrew the nut that secures the flexible coupling flange, then remove the centering ring
Remove the flange and lock washer
seal and apply sealant
The final step is to press the oil seal into the gearbox using a suitable mandrel. We install all the parts that were removed in the reverse order. We check what level the oil is at; if we see that it is not enough, then we need to top it up.

Niva Chevrolet backstage adjustment

In any vehicle, the gearbox is one of the main units that determine the quality of the car's ride. Accordingly, the occurrence of breakdowns in the operation of power units will, one way or another, affect the driving of the car, especially when it comes to the gearbox control lever. Today you will learn how the Niva Chevrolet rocker is changed and adjusted and how to choose a new component for your car.

Backstage repair

The gearbox linkage is an element of a multi-lever assembly, which is designed to connect the gearbox lever and the rod that fits the power unit. In Niva Chevrolet cars, the rocker is located under the bottom of the vehicle, next to the cardan. This component is susceptible to contamination and the formation of moisture on it, which over time can deteriorate the quality of lubrication of rubbing parts. As a result, parts begin to wear out, which can subsequently lead to various problems.

Chevrolet Niva car & 2013 model

As stated above, the rocker is an integral part of the transmission system in Niva Chevrolet cars. Compared to other components of the transmission system, the rocker, which is also called the gearbox control rod, is a relatively simple mechanism in its structure

However, for correct operation, the condition of the scenes should also be given special attention.

In particular, we are talking about timely repair and adjustment of drive traction. If you want to avoid unexpected unpleasant surprises while driving, then the condition of the scenes should be at the appropriate level.

On most cars, this element is a fairly reliable mechanism that can easily last up to 100 thousand kilometers without replacement. But no one is immune from the breakdown of this unit. How to determine the need for backstage repair? This can be done based on several factors:

the play of the gear shift lever in your Niva has increased significantly;
Difficulties arose with shifting the gearshift lever;
Reverse gear does not engage;
adjustment of the component has become impossible.

An old element of the transmission system that has expired its service life

If the speeds start to turn on very slowly or the speed that should turn on is not the one that should turn on, you can try to adjust the mechanism. Of course, this is only relevant if the condition of the drive can be visually assessed as working. If the connecting elements of the mechanism's hinges operate with a large amount of play, then it would be more advisable to replace the component.

How to choose a new backstage?

What kind of rocker should I put on a Niva Chevrolet? This question came to the mind of every Niva car owner who had to deal with a malfunction of this element. In fact, there is nothing difficult in choosing a component.

Chevrolet Niva (2009+). Gears are difficult to engage

Reasons for difficulty shifting gears

Possible causes of malfunction	Troubleshooting
Clutch faulty	Carry out diagnostics
The selection cable or gear shift cable is faulty (broken, torn, stuck in the sheath)	Replace the faulty cable
The gearbox control mechanism is worn or damaged	Replace mechanism
Worn or damaged gear shift mechanism	Repair or replace transmission

- Clutch malfunction. In this situation, the gears will engage either poorly or not completely.

-The breakdown is usually accompanied by a grinding noise when switching to another speed.

Manual transmission (gears are difficult to engage)

There are also several clutch malfunctions that cause manual transmission gears to shift poorly:

Price

Finally, we come to the most pressing issue - cost and maintenance costs. And if the VAZ 2131 and VAZ 2121 are approximately in the same price category, then the Chevy will cost the buyer 1.5 times more. Not everything is so simple with service.

DETAILS: Niva Chevrolet fuse box with description

The result is cars with the same technical components, but with some features of their installation or configuration. Unfortunately, these features come at a price. Thus, maintenance of a Chevrolet Niva, in terms of a certain mileage, will also cost more. It is traditionally believed that the availability of spare parts for Shevik is lower, but at present this information is no longer relevant. As a result, it can be noted that among all Niva models there is no clearly defined flagship, and each model finds its buyer.

Cross-country ability - not increased, but high

The cross-country ability of permanent symmetrical all-wheel drive with reduction gear and locking in the Niva transfer case cannot be overestimated. She visited both poles of the planet, climbed Everest (and reached the 5500 m mark). But these are ceremonial records, and thousands of modest workers ensure the transportation of people and small cargo in our off-road conditions. And what also speaks about the cross-country ability of the car is that in any mud trophy to this day, forty years after birth, along with “Defs”, “UAZs” and “Gelikas”, our dear Niva.

First of all, under the hood of the Chevrolet Niva, the nut of the screw securing the tip of the gearbox lever with the gear shift rod is loosened.

After this, you should go down into the pit again, but tighten the loosened clamp bolt.

How to choose a new backstage? What kind of rocker should I put on a Niva Chevrolet?

This question came to the mind of every Niva car owner who had to deal with a malfunction of this element. Before installing the seals, they will need to be lubricated with Litol. This completes the repair of the product; all that remains is to assemble all the parts in the reverse order of removal. Once assembly is complete, don't forget about the new clamp that had to be cut when removing the cover.

Video instructions: adjusting the scenes on a Chevrolet Niva

And a few words about the transfer case rocker The transfer case rocker performs similar functions to a boxed product, only the speed mode shift lever is not used as often as the transmission. From this it follows that the transfer case rod has a much longer service life.

If similar problems are noticed as in the gearbox, then it is worth replacing the transfer case, since its mechanism does not allow repair or replacement. Based on all that has been said, the gearbox and transfer case are important elements of the Chevrolet Niva, without which it is impossible to engage gears.

Chevrolet Niva gearbox lever play

https://youtube.com/watch?v=_81NpHFPdSo

It worked the first time. A month or two passes, and it’s already April. I can’t turn on the rear one. Come on, off into the wilderness, shouting “not Russian words,” I put chains on all the wheels.

We managed to switch on some gear, and, accordingly, it was liquefied.

We move the lock to the extreme position on the right. Then tighten the loose bots securing the scenes from the pit.

After such actions, the work of adjusting the scenes can be considered completed. Use a screwdriver to push the rubber-plastic guide sleeve inside the lever housing and slide it along the shaft.

Remove the four bolts securing the lever housing to the body base. Remove the housing and remove the shaft from it. Using a wrench, you unscrew several screws holding the gear shift lever housing to the car body.

Repair and replacement of the rocker on a Chevrolet NIVA

After dismantling the housing, the gearbox shaft is removed from it. Next, the guide rod is removed from the shaft. If there is a large play in the hinges of the detected link that cannot be adjusted or the hole for the axle is too worn, then the mechanism is removed and replaced with a new one.

To turn it on, you can start the engine and move the gearbox lever until the car starts moving. Afterwards, the engine is turned off, the first gear remains on, and shoes are placed under the wheels.

Don't forget the handbrake. Lower into the overpass and loosen the bolt of the rocker clamp. Inside the car we find a plastic traction lock and move it to the extreme left position until it stops.

After this, you should go down into the pit again, but tighten the loosened clamp bolt. At this point, the gearbox thrust adjustment is completed, and you can check its performance.

Gear shift mechanism

The gear shift mechanism of the Niva Chevrolet SUV is due to the presence of a plate with cutouts. The cutouts are rectangular in shape and there are eight of them. The mechanism also includes: two washers (upper and lower), a lever and the main body. All these box components are held together with three bolts.

The position selection mechanism is based on three pins that are held on the back cover of the box. The “neutral” position is between the third and fourth speeds and is achieved by two pairs of bars with spring guides. The plates are located in the grooves of the guide plates due to which a mechanical effect is provided on the lower end of the lever.

The control drive is based on three rods, which are interconnected with forks. The engagement of forward gears is ensured by the fact that the forks fit into the holes of the sliding clutches. The reverse gear is activated by the fork entering the hole of the intermediate gear.

On the ancestors of the Niva Chevrolet SUV, there was a possibility of introducing a rear instead of a fifth. On modern models this possibility is excluded. An exception is provided due to the presence of a blocker, which is attached to the fork of the rod end. The locking mechanism is attached to the gear shift lever of an SUV.

To engage reverse, you must depress the clutch, and then press the shift lever down and move it to the “R” position. The mechanism for engaging the rear is provided by lowering the locking stop to a position below the locking pad. When the speed is turned on, they are lubricated by splashing oil in the box. To avoid oil leakage from the gearbox from the primary and secondary shafts, these places are sealed with oil seals, which periodically require replacement.

Gear shift diagram for Niva Chevrolet

On most passenger cars, the switching pattern is identical. The exception is the inclusion of rear and fifth speeds, but on rear- and all-wheel drive vehicles of the VAZ family this order is always the same. So, let's look at the location of all the gears in the box and how they are engaged. Below is a diagram that will make it easier to understand.

Once behind the wheel, the driver sees not one lever under the dashboard, but two. In this situation, we are interested in lever number “1”, since it is the basis of switching. Lever “2” is designed to engage the differential locking of the wheels, but you can read more about this in the article about differential locking.

So, as you can see, the scheme is standard, the first four speeds are the main ones and are turned on in turn. To engage fifth speed, move the lever to the extreme right position and press forward. To engage the rear, you must still press the lever down in the neutral position, then move it in the same way to the right position and press it back. Thus, a certain position of the lever on the Chevrolet Niva is activated; below is a table corresponding to the optimal speeds for each gear, which will be very useful for beginners to know.

Provisions	Travel speed, km/h
1	20
2	40
3	60
4	90
5	over 90

The table says that when these speeds are reached, the next gear must be engaged, but most experienced drivers do not even look at the speedometer needle when engaging a particular gear. When transitioning, you should fully depress the clutch pedal, since the gearbox is mechanical, and also remove your foot from the accelerator (gas) pedal.

Malfunctions

Particular attention should be paid to malfunctions, which are important to detect at the first signs and take appropriate measures.

Any malfunction that has arisen can be determined, first of all, by the first signs, and those for the transmission are: noise, knocking, impacts felt by the hand when switching, as well as jerks when the car starts to move. So, in order to eliminate certain malfunctions, you need to know the root cause, i.e., what they indicate. The most common and likely signs of transmission problems are:

presence of noise;
difficulty switching;
spontaneous shutdown of gears (popularly called “knocking out”);
leaks of lubricating fluids.

Often, car owners complain about knocking in the transmission, which occurs literally after 5-10 thousand kilometers. What do they testify to? To answer this question, consider the symptoms of malfunctions and causes in tabular form:

Sign	Type of fault or cause
Knock in neutral position	The drive shaft bearing may be worn or the oil level may have dropped.
Knock when switching on (switching) speed	The locking device is worn out
	Synchronizer clutches were worn
	Transmission mount connection loose
Knock in the box while driving	Worn bearings or synchronizing clutches
Knock in the box while driving	The oil level in the box has dropped
Shocks when switching and starting	Worn synchronizing clutches or output shaft
	Incomplete clutch pedal depression
	Low oil level (if the shocks are repeated continuously)
	Possibly gear wear

It is rare to observe the phenomenon of failure of the scenes. The link is a unit that connects the transmission lever and the rod that fits the box. Signs that the linkage may fail are as follows:

Inherent large play of the transmission lever;
Difficulty changing speed;
Complication when adjusting the mechanism.

If erroneous gear shifts occur or difficult shifts occur, then it is worth resorting to adjusting the transmission drive. Jerks after switching and while driving indicate, first of all, a possible malfunction of the clutch basket, that is, it is necessary to replace the discs and pump the brake fluid. Also, jerking may indicate a failure of the release valve. When repairing the clutch, you need to pay attention to all the components of this mechanism.

Purpose and design of the gearbox gate

The rocker is technically called a box drive rod and is an all-encompassing mechanism designed to connect the box shift lever with the box rod.

On Chevrolet Niva jeeps, the rocker is located in the cabin near the lever itself, as in almost all models of Russian cars. It’s not difficult to find it if you know what a box is. The rocker is located near the gearbox shift lever and has the appearance shown in the photo below.

Photo of the backstage located in the vehicle interior

On older vehicle models of the Russian automobile industry, the location of the rocker was located under the bottom of the car, but this initially reduced the service life of the product, which affected efficiency.

Backstage adjustment

The slide on Chevrolet Niva jeeps has a long service life, equal to more than 100 thousand km. But this resource depends, first of all, on the integrity of driving, therefore from time to time drivers may notice malfunctions in the operation of the gearbox, such as:

When you try to engage first gear, it switches to reverse;
5th speed is lost when it is turned on;
Reverse gear is engaged when selecting front 5 gears.

This indicates a malfunction of the drive rod, but do not rush to remove the gearbox and repair it, because you can try to adjust the product. Although adjustment is a rather complicated task, it is easier and cheaper if you change the box or the link.

Placement of the rocker clamp bolt

Adjusting the backstage includes the following steps:

The gearbox is engaged in 1st gear. To turn it on, you can start the engine and move the gearbox lever until the car starts moving. Afterwards, the engine is turned off, gear 1 remains on, and boots are placed under the wheels. Don't forget the handbrake.
Lower into the overpass and loosen the bolt of the rocker clamp.
Inside the car we find a plastic traction lock and move it to the last left position until it stops.
After which you should go down into the pit again, but tighten the loosened clamp bolt.

While driving through the forest, a hinge popped out of the drawstring

, I had to drive home in only 3rd gear….

Removal and installation of the box and minor repairs.

At this point, the gearbox thrust adjustment is completed, and you can check its performance. If the adjustment does not help, then it will be necessary to remove and repair the product.

Mechanism malfunctions

If, after the procedure for regulating the traction of the transmission of a Chevrolet Niva car, subsequent malfunctions are identified, which appear in the form of:

the free play of the gearbox lever increases;
difficulty changing gears;
speeds are turned on tightly;
Engaging in the wrong gear or inability to switch gears.

Engaging reverse gear on a Chevrolet Niva! — Forum of smart people

This may simply require adjustment of the rocker itself.

When the speed is turned on, they are lubricated by splashing oil in the box. The whole procedure took 15 minutes with a photo session of the clamp.

Reverse gear does not engage on a Niva Chevrolet, what should I do?

I got to the shitty place, they hit the gas and jerked off, and took off. Then there was no need for much gas, it began to fly out. The transmissions of the VAZ Niva fly out. I made a mistake by sparing the effort on the nut.

The locking mechanism is attached to the gear shift lever of an SUV. The mechanism for engaging the rear is provided by lowering the locking stop to a position below the locking pad. When the speed is turned on, they are lubricated by splashing oil in the box.

The driver presses the clutch and takes out third gear. Therefore, by pushing the lever, we require the synchronizer to spin the input shaft almost from zero to rev!

But the resource can be greater. It all depends on the accuracy of the driver and the operating conditions of the vehicle.

Removing gearboxes on Niva Chevrolet

What are the main faults when it is necessary to remove the gearbox:

Exhaust tip Ensure that it is present and does not show signs of visible corrosion: there are cases where it falls off and causes a concentration of hot gases in the barrel floor, aggravated by the lack of thermal insulation in place. In extreme cases, it can even melt the liner.

Ignition Symptoms of a system malfunction include a flashing panel fault indicator and minor engine failure. The scanner almost always indicates a defect in the coil, which costs about 500 reais in an authorized one. And the space is great even for tall people. I don't like the finish: it's very plasticky and noisy, especially in the trunk lid and glove box, which doesn't close properly. Consumption could be better.

It's difficult to change gears
Various noises appear
The gears switch on themselves or, on the contrary, switching off is difficult
Oil is leaking

Its removal is also required when replacing the clutch.

To remove the gearbox:

Place the car on a pit or a special lift
Disconnect the terminals from the battery, remove the protection
Drain the oil from the box
The front driveshaft and intermediate shaft should be removed
Disconnect the wires from the reversing lights
We remove the cover of the handle with which we change gears
Unscrew the handle and remove it with the cover together
We unscrew the nut that secures the support plate of the PP mechanism and remove the rear power support unit
We unscrew the nut and the clamp that tightens the mechanisms that change gears
Remove the MPP drive by unscrewing three bolts
Unscrew the bolts that secure the clutch housing shield
We remove it from the hose by unscrewing the two bolts of the clutch cylinder
Removing the lateral stability stabilizer
We remove the entire mechanism assembly, namely the clutch housing and gearbox

Thus, having completed all the points, you can change the oil or the entire gearbox on a Chevrolet Niva yourself, the process is not entirely automatic, so you will have to work hard.

Experts note that during the operation of a Chevrolet Niva, something happens that it stops engaging in reverse gear. This happens due to the fact that the car has a worn-out rocker, which plays an important role when changing gears.

It should be noted that in the Niva Chevrolet there are two such scenes: one is for changing gears, and the second is for switching the transfer case.

The main stages of replacing fluid on a Chevrolet Niva:

We substitute a prepared special container under the place where there is a special hole through which waste is drained from the gearbox housing itself.
To drain easily, remove the plug from the holes that are responsible for filling and draining the oil, and drain it.
After the oil has been drained, the drain plug must be cleaned of various contaminants and inserted into place. If the oil that you drained contains a lot of contaminants or contains a lot of impurities, then the gearbox is washed, after which about nine liters of special flushing oil is poured into the crankcase itself, and the plug is screwed back into the oil filling hole.
We hang up all the rear wheels or one, engage first gear and start the engine, it should run for about three minutes.
After the engine has been running, drain the flushing oil, wipe the oil drain plug and install it in place.
Using a special device or a regular syringe, pour new oil into the crankcase. Fill in 1.6 liters. After the entire procedure is completed, we put the plug in place.

At this point, the process of replacing the fluid in the box can be considered complete.

Of course, there is no option for an automatic transmission or other motorization. Engineers modernized the old platform and added a number of standard features and a new brand identity: wide split railings. Despite the controversy, the styling continued its success, with the public captivated by the generous interior space, elevated driving position and 327-litre boot.

A high ground level works well in urban groves without compromising stability. But he wants to finish, high level of noise on the road and parts such as pedals, air leaks that let water into the cabin, trunk that can only be opened with the key and any injection and ignition locks.

Do-it-yourself gear shift assembly adjustment

To correctly adjust the gear selection mechanism you will need a 13 key

Sequencing:

We start the engine, engage 1st gear. As soon as the car starts to move, we stop and turn off the engine. In this case, we leave the first gearbox speed in the ON position. We put the car on the handbrake and anti-rollbacks.
We loosen the coupling bolt of the clamp securing the connecting rod of the gearbox under the body. For ease of work, you can use a lift, overpass, pit or jacks.
We move the plastic traction lock located in the passenger compartment all the way to the extreme left position.
Then we fix the loosened bolt of the mounting clamp back.

You can also try one more method to eliminate rattling and play in the gearbox handle: using a “13” wrench, you need to tighten the lever fastening nut until the axial play is eliminated.

Important! The permissible clearances of the drive unit must correspond to the following values in millimeters: D = 1.5 ± 0.5; E = 1 ± 0.5. The lever nut must be tightened to a torque of 24.5 Nm (2.5 kgfm)

The lever nut must be tightened to a torque of 24.5 Nm (2.5 kgfm).

If, after the adjustment has been made, the same difficulties with gear shifting and vibration remain, this means that this unit is worn beyond the permissible norm and needs to be replaced.

Reverse gear does not engage on a Niva Chevrolet, what should I do?

Chevrolet Niva gearbox, 5th gear

Like I went on a tractor. We climb under the car and tighten it further until it is fully tightened. We get out from under the car and set the lever according to the diagram, see.

Niva, gears are difficult to engage. knowledgeable and understanding plz. Yesterday I went to Niva to pick mushrooms. On the…

The gear shift lever began to “float” The first gear does not engage if I turn on the third and move it to the right all the way without turning off the gear and turn it off Road construction work is being carried out, well, almost throughout the city. At some point you will hear a sound like a children's inertia car if you accelerate it too much.

I can say right away that a decent load on the synchronizer begins already with the resulting revolutions. The control drive is based on three rods, which are interconnected with forks.

Well, I’m in the back, but she’s not there. Without nerves, in third gear and only forward to the curb, I’m in a jeep.

And after work, without unnecessary fanaticism, we think: “Why is it constantly unscrewing?! Maybe it’s for countering, there’s a counter washer there. Or maybe I’m not tightening the clamp properly? Before adjusting the rocker, you need to use the lever to catch neutral. A lift is not needed at all, we can easily crawl under the car.

I could not get! We get out from under the car and set the lever according to the diagram, see.

On modern models this possibility is excluded. An exception is provided due to the presence of a blocker, which is attached to the fork of the rod end.

The locking mechanism is attached to the gear shift lever of an SUV. The mechanism for engaging the rear is provided by lowering the locking stop to a position below the locking pad.

When the speed is turned on, they are lubricated by splashing oil in the box. The problem is the early engagement of the “low” gear.

The driver presses the clutch and takes out third gear.

Therefore, by pushing the lever, we require the synchronizer to spin the input shaft almost from zero to rev! Of course, until he spins it, the transmission won’t stick in!

That's why when the lever rests, there is no need to drive it in with force. It is recommended not to rush to remove the gearbox itself and carry out repairs.

This may simply require adjustment of the rocker itself. Despite the fact that such a task is quite troublesome, it is less expensive than repairing or replacing the entire gearbox.

Repair of the 5th gear of the Chevrolet Niva gearbox Chevrolet NIVA

Engage reverse gear and move away. Then turn off the engine and leave the gear engaged, putting shoes under the wheels and putting the car on the handbrake.

On the overpass, loosen the bolts securing the rocker.

Transmission linkage: removal

The rocker on a Niva Chevrolet SUV is removed in the following order:

Open the hood of the car and find the clutch tip of the lever, as well as the gearbox linkage. The rod has a turnbuckle with a protective cover that will need to be removed.
In the Shnivy interior, remove the trim of the gearbox lever using a screwdriver. You should be careful not to damage the latches.
Turn the cover the other way, and then cut the fastening clamp. Next you need to remove the cover from the lever.
Remove the front of the floor tunnel lining.
Unfasten the fasteners from the lever and remove the axle.
Remove the shift lever by moving it up, and the remaining rubber cuff must be returned inside the removed lever.
Remove the lever housing fixing bolts and remove the rocker.
Remove the rod (rubber sleeve) from the shaft.
Observe the rod for damage or defects. This way it will be possible to determine whether the backstage requires repair or replacement.

Replacement should be carried out if there is a gap in the hinges or serious wear of the play under the axis of the speed shift knob. If the boot is damaged, you will have to replace it with a new one. So, you need to cut off the worn boot and remove it, installing a new one in its place. You should first lubricate the internal parts with Litol.

In other cases, it’s time to repair the backstage. You will need to buy a repair kit in advance, which contains plastic seals. Before installing the seals, you need to lubricate them with Litol-24. After completing the repair, all that remains is to assemble all the parts in the reverse order of removal. Upon completion of assembly, it is worth remembering the new clamp that was cut when removing the cover.

clutch Renault Duster

Rear axle gearbox with electromagnetic clutch Renault Duster.
A similar unit is used on other Renault cars: Kaptur and Koleos. And it was originally developed and used on the Nissan X-Trail from the very first generation and Nissan Qashqai from the moment this model appeared. Rear axle gearbox with electromagnetic clutch Renault Duster. A similar unit is used on other Renault cars: Kaptur and Koleos. And it was originally developed and used on the Nissan X-Trail from the very first generation and Nissan Qashqai from the moment this model appeared. To control the compression force of the clutch discs, a cam mechanism is used that changes the clamping force. The voltage applied to the clutch solenoid causes the clutch discs to close and engage the rear axle. The amount of transmitted torque is regulated by the adhesion force of the friction discs in the clutch. So, if the voltage supplied to the electromagnet is reduced, the clutch will provide an incomplete circuit and will be able to rotate with a small torque. However, even with full voltage applied, a closed clutch can transmit a torque limited by the friction forces in the clutch.

Replacement and repair of Niva Chevrolet gearbox

Replacement and repair are the same thing. In both cases, the gearbox is removed. Only in one is disassembly and troubleshooting, in the other is the process reverse to removal - installation of a new gearbox. Removing the gearbox is performed in the following sequence:

The gearshift knob is removed from the interior side. To do this, you need to press the lock with a screwdriver. However, you don’t have to remove it at the root, but simply unscrew the handle.
In order to lighten the weight of the box and prevent oil from leaking, it needs to be drained. There is nothing complicated, the process is similar to draining oil from the engine.
After this, remove the driveshaft that goes to the transfer case. A mark is required before removal.
Remove the flush shaft and the mechanism responsible for selecting the desired speed.
When removing the box, the exhaust pipe will get in the way. Another name for it is “pants”.
After this, everything attached to the gearbox is removed - the speed sensor and the clutch cylinder. Thus, it is necessary to release everything that is attached to the box and the engine at the same time. All that remains is to unscrew the fasteners and with a partner pull out the gearbox. However, this can be done alone - using a special stand.

There is nothing complicated about repairs either. The box is completely disassembled and defective. It is necessary to inspect the gears for wear. For quality repairs, worn components need to be replaced. Be sure to replace all oil seals and seals. It wouldn't hurt to change the clutch right away. It is recommended to replace the bearings without fail.

It is worth noting that the weak point is 5th gear. She stands higher than the rest and receives less lubrication. Determine the condition of the latch. If it is worn out, the 5th will fly out at speed, which is not very pleasant or comfortable. In addition, it can fly out due to wear of the gear teeth. The unscrewed shank nut also makes its contribution. Do not forget about backlash in the mechanisms - they are unacceptable, otherwise they will manifest themselves in knocking when starting off.

The gearbox is installed in the reverse order of removal.

And maybe someone will sit down at TO1 to check it - and everything will work as it should, the law of meanness. It can be countered, because there is a counter washer there. At the moment the speed is turned on, they are lubricated, carried out by splashing oil in the box.

The fifth speed may disappear when turned on. Apparently it works, but not for everyone.

Remove the gear selection mechanism drive. Unscrew the two nuts securing the bracket to the support plate. Remove the bushing plate from the holes. It is advisable to block the differential on a slippery surface, for which you need to stop the car and drive about 1 m in the opposite direction or allow partial wheel slip.

So, let's look at the location of all the gears in the box and how they are engaged.

Below is a diagram that will make it easier to understand. So, as you can see, the scheme is standard, the first four speeds are the main ones and are turned on in turn.

Fill with oil to the level of the oil filler hole of 1.6 liters. The transmission oil change is complete. Replacing the Niva Chevrolet secondary shaft oil seal A constant decrease in the oil level in the Chevy Niva gearbox housing can be caused by a loss of tightness of the transmission secondary shaft seal. To replace the secondary shaft oil seal, you will need a 30 mm wrench, a screwdriver, a mandrel and a hammer.

To replace the secondary shaft oil seal, remove the transmission intermediate shaft. Remove the centering ring seal and unscrew the nut securing the elastic coupling flange. Remove the centering ring Remove the lock washer and flange Using a screwdriver, remove the oil seal from the rear cover of the gearbox, apply sealant to the new oil seal. Press the oil seal into the rear cover of the Chevy Niva gearbox through a suitable mandrel. Install all removed parts and the intermediate shaft in the reverse order of removal.

Eye-catching differences

By comparing these automotive industry products in more detail, you can understand their differences:

The Volzhsky Automobile Plant produces Niva 2131 independently. The Chevrolet Niva is produced in a joint venture with GM.
The engine power is not the same. The extended version of the Niva 2121 has a more powerful engine. 83 horsepower versus 80.
Chevrolet's maximum torque is lower than that of 2131.
The fuel tank capacity of the 2131 differs by more than 10 percent and is 65 liters.
420 liters of usable space in the trunk of the Niva 2131. The Chevrolet trunk has a volume of 320 liters.
The acceleration time to a speed of 100 kilometers per hour is also different. The Chevrolet does it in 19 seconds, which is 1 second faster than its counterpart.
2131 has a smaller mass and is 1350 kilograms. The competitor weighs 60 kilograms more.
Chevrolet's ground clearance is 200 millimeters. A classmate’s is 20 percent larger – 240 millimeters.
Chevrolet's average fuel consumption per 100 kilometers is 10.2 liters. Consumption 2131 - 13.8 liters.
Tire sizes also vary. Tires with the index number 205 are installed on an automobile product of a joint production, and tires with an index number of 235 are installed on a purebred brainchild of a domestic manufacturer.
Joint production began in September 2002. Niva 2131 has been produced since March 1993, which is 9 years longer.
The jointly produced machine is distinguished by richer technical equipment. Already the basic version includes a driver's airbag, central locking and connectors for modern electronic devices.
More than 700,000 Chevrolet cars sold. For colleagues, the figure is several times lower. And this despite the fact that 2131 began production 9 years earlier.
The average cost of a Chevrolet vehicle is RUB 750,000. The average price for a home-grown 2131 is 590,000 rubles.

The geometric parameters of the car body are different:

Car make	Body length (mm)	Body height (mm)	Wheelbase (mm)
Niva 2131	4240	1665	2700
Chevrolet Niva	4056	1652	2450

How to choose a new backstage?

In practice, many car owners of the above car models install mechanisms from classic Fiat cars on their vehicles. According to reviews on the Internet, these devices are completely suitable for installation in a Chevrolet Niva. However, there is also a negative side. In practice, Niva cars equipped with a mechanism from Fiat cars require more careful adjustment of the element. In addition, despite Italian quality, these components of the transmission system are more susceptible to wear and tear.

Therefore, when choosing a mechanism, you should not “be fooled” by the stories of handicraft “garage” craftsmen and come up with a new headache for yourself. For installation in a Chevrolet Niva, it is better to purchase a standard rocker, which is equipped with basic models of Niva cars.

New rocker for Niva Chevrolet

Replacing an element

As a rule, the need to repair this component arises after installing or repairing the gear shift drive. If you have replaced the drive, but when driving you feel how the vibration of the gearbox lever remains, then, most likely, there is increased play in the lever hinge mechanism. This means that the hinges should be repaired, and accordingly, it may be necessary to replace the rocker.

If you decide to replace a component at home yourself, then prepare in advance everything that you may need during the work process. In particular, we are talking about:

wrenches on "12";
wrench set to “14”;
socket wrench at “10”;
clamp for securing the gearshift lever cover;
stationery knife;
Phillips screwdriver.
