Installing the generator belt tensioner on viburnum

Belt selection and price

If the generator design has a tensioner, then the belt length is 883 mm. In the vast majority of cases, Kalina has 8 valves. If the generator is like on Grant, the length is 823mm.

When choosing a manufacturer, you should take into account that the official supplier of these belts for AvtoVAZ is the GATES company, therefore preference should be given to its products. Belts are also created by BTR (many bad reviews), Continental, Finwhale, and ANDYCAR. It is better to buy Dayco 825 (manufacturer GATES), elastic belts are marked Poly-V, if not, then the belt is rigid. The cost of belts is approximately from 500 to 1000 rubles.

Remove the belt from the roller and all pulleys.
Turn the belt a little and pull it out.
Start a new belt, put it on the roller and pulleys.
Reassemble in reverse order.
Start the engine, let it run for a while and turn it off.
Adjust the belt tension.

The entire procedure for replacing a belt will take on average 2-3 hours; if you have an assistant, it can be significantly reduced.

A couple more tips. If the car has run 60 thousand km, the manufacturer recommends replacing the roller. If the old alternator belt is not completely worn out, it is better to put it in the trunk as a reserve.

A few words about the elastic belt; there is no need to adjust it; it is wound up first on the pulley and then on the generator, put in gear and push the car, having previously slipped a mounting tool or something similar under the belt.

Adjusting the alternator belt on Kalina

The first thing we need to do is loosen the tensioner rod lock nut by unscrewing it slightly counterclockwise:

And then we unscrew the tensioner rod, and thereby the belt will be tensioned. To avoid having to put a lot of effort during tensioning, you need to press the tensioner body with your hand and unscrew it at the same time, as shown in the photo below:

After tightening the belt, tighten the lock nut and check if there is no more whistling noise when the engine is running. To make sure of this, you need to turn on as many electrical appliances as possible with the engine running: high beams, heater at high speeds, rear heated glass, etc. If the belt does not whistle after performing this procedure, then it is tensioned normally.

But you should also keep in mind that reupholstering will also not benefit the device. Firstly, the belt itself will wear out a lot. Secondly, the bearing will not withstand heavy loads, it will hum and may even jam within a fairly short period of time. Once on a previous car I had a sad experience: I pulled it too tight and after a week of driving the bearing had to be replaced. So don't go overboard when performing this type of maintenance on your Viburnum.

If, on the contrary, it is necessary to loosen it, then you will need to tighten the rod clockwise. Then tighten the locking nut. These seem to be all the recommendations you need to know when performing this simple procedure. If you have any questions or comments on the material I prepared, please leave a comment.

When to change?

VAZ Lada Kalina vehicles use a belt drive for auxiliary units. On cars with air conditioning, the service life of such a belt is no more than 30 thousand km. On simple versions of cars, the strap can last longer, but most owners try to change it after the same 30 thousand kilometers traveled. For various reasons, the belt may fail earlier, so it must be checked periodically during vehicle operation. There should be no cracks on the working track, and delamination on the outer part of the belt is unacceptable. If such defects are present, we immediately change the strap. Another signal to replace this element is a whistle or other noise when the unit is operating.

Lada Kalina: alternator belt tensioner, check and replacement

It often happens that the belt itself is in good condition, without obvious defects. However, it cannot be tensioned due to the fact that the Kalina belt tensioner has failed. Next, we will look at how to replace the alternator belt on Kalina with your own hands, as well as how to change the Kalina tension roller.

Belt and roller selection

Several types of belts are used on Lada Kalina cars.

The type of element depends on the engine model and its equipment:

The motor version without air conditioning and tensioner has a belt length of 823 mm. Gates (number 6PK823) is standardly used, but such a part is not supplied as spare parts. To replace it, a slightly different strap is used - Gates 6PK823SF.
The version of the unit with a belt tensioner, but without air conditioning is 882-884 mm. Standard part manufactured by Gates (article 6PK882). In addition to it, straps are often used - Finwhale BP6883, Dayco 6PK888 or the cheapest Balakovo belt BRT882.
Engine with air conditioning and belt tensioner (motor 11183) - 1018 mm. Standard element manufactured by Gates (number 6PK1018). Alternative options are Dayco 6PK1018 or Continental 6PK1015.
The 21127 16-valve engine with air conditioning and tensioner uses a 995 mm belt. The Gates part (6PK995) is supplied from the factory, and it is also used as a spare.

Sometimes when replacing a belt it becomes necessary to install a new tensioner. It is the same for all motors, its article number is 2123–1041056.

How to change it yourself?

The complexity of replacing the alternator belt on Kalina does not depend on the number of valves or additional units on the engine.

Replacement on 8 valve engines without tensioner

Replacing the belt on such an engine is the simplest; the only tools you need are a 13 mm wrench and a short flat-blade screwdriver. Since the tension in such a drive scheme is quite strong, when changing it is necessary to use only a Gates 6PK823SF or Dayco 825 six-V belt with the additional marking POLY-V. The remaining straps are too rigid, quickly collapse and damage the bearing on the generator shaft.

Stages of work

To complete the task you need to do the following:

Unscrew the lower mounting bolt of the generator 2-3 turns.
Unscrew the nut of the upper fastening, use a screwdriver to push out the bolt and remove it completely.
Lower the generator down. The eye of the mechanism must pass through the gap between the radiator and the TV body.
Remove the old belt and replace it with a new one. If the strap does not fit easily onto the pulleys, you can carefully tighten it using a screwdriver.
Raise the generator up, ensuring the belt is tensioned.
Insert the upper mounting point bolt and tighten the nut.
Tighten the lower mounting point bolt.
Check the operation of the belt.

The repair process on such an engine is clearly shown in the video filmed by the author Ilgiz Magafurov.

Replacement on 8 valve engines with tensioner

Here, the procedure for installing a new alternator belt is very different from that presented above.

Required Tools

To replace the alternator belt yourself, you will need at least the following tools:

regular or box wrench for 13, 17 and 19 mm nuts;

a head with a ratchet for 8 mm nuts; if it is not available, an open-end or regular wrench of the same size will do;

a screwdriver with a thin flat blade;

thin needle;

rags;

white spirit or gasoline, approximately 0.5 liters;

container and brush for washing;

CV joint bearing lubricant.

Stages of work

To adjust the degree of belt tension on Kalina engines, a mechanical tensioner is used, in contrast to the timing drive, which uses a hydraulic tensioner. When changing an element, it is recommended to carry out preventive maintenance of the roller by adding fresh lubricant.

To complete the work you need to do the following:

Loosen the roller bolt. The thread on it is reversed.
Use a screwdriver to pry up the plastic plug on the roller and carefully remove it.
Unscrew the fixing nut on the tensioner rod a few turns.
Loosen the belt tension by rotating the rod nut clockwise. The nut must be unscrewed until the rod begins to move freely in the seat.
Unscrew the side bolt securing the rod end, located next to the tension roller.
Remove the tensioner and set it aside.
Proceed to dismantle the strap. The procedure must begin with the generator pulley, while overcoming the slight resistance of the belt.
Remove the element from the crankshaft pulley and remove it completely.
Unscrew the roller bolt and remove it.
Using a needle, carefully pry up and remove the protective caps on the bearing. Wash the bearing with white spirit or gasoline.
Refill with fresh grease and install protective rubber caps.
Assemble all the parts and mount the roller in place. When assembling, you must remember that the bushing is in the bearing on the side of the bracket.
Change the belt by installing it in the reverse order - from the crankshaft pulley to the generator pulley.
Install the tensioner and begin tightening the belt by turning the nut counterclockwise. The nut must be tightened until the resistance increases. A well-tensioned strap should be slightly pressed when pressed by hand.
Tighten the nut securing the tensioner rod.
Check the operation of the mechanism; if a whistle occurs, tighten the strap.

We check the condition of the alternator belt ourselves

Before Lada Granta alternator belt

, car owners usually inspect its condition to make sure whether this is really necessary. Replacing the alternator belt - renault megane forum (Renault Megane. To make a diagnosis, you need to perform the usual steps. First you need to turn on the fifth gear and get out of the car, then try to push your Grant back, acting on the front bumper or side pillar, if this will do assistant In all this, the hood must be open and while pushing you need to see how the RG behaves.

We recommend: VAZ 2115 won’t start - what to do

Worn and damaged RG, unsuitable for operation

There should be no signs of damage on the strap when pushing the car. Replacing the timing belt for a Renault Megane with a 1.6 engine. We are talking about cracks, delamination or breaks, even the smallest ones, although this can completely happen, especially with frequent use of the vehicle. In this case, if during the diagnostic process you see traces of damage on the RG, this indicates that the belt

If it doesn't work, it needs to be
replaced .
The timing belt is diagnosed in a similar way. If you don’t need to tighten the RG and adjust the tension on an 8-valve engine, you can also check the condition of the generator itself. After all, if you have any suspicions about the quality of the work of the DG, it makes sense to check the device itself. [09] DIY alternator belt replacement. —. In addition, during diagnostics, you can also check the generator belt , with which the belt can be tensioned. If there are chips on the roller or other signs of deformation and damage, including changes in geometry, the element must also be replaced. The video below provides detailed instructions for replacing the bracket, as well as the alternator strap on a Lada Granta (the author of the video is Igor Semenishin).

Replacement cost

The cost of changing a belt on a Lada Kalina car depends on the type of engine, range of units and is:

for a motor without a tensioner - from 300 rubles;
engines with a tensioner without air conditioning - from 150 to 350 rubles;
motors with tensioner and air conditioning - from 220 to 400 rubles;
for unit 21127 - about 600 rubles.

Replacing the roller will require an additional 250 rubles. The total amount required by the car owner to purchase spare parts, in the maximum version, will not exceed 850 rubles.

In what cases does the strap need to be replaced?

In accordance with official data, the manufacturer does not provide for the repair and replacement of the strap in a Lada Kalina car with 8 or 16 valves. However, this does not mean that the strap can work forever - like any other consumable, it wears out over time and must be replaced. Moreover, a broken belt for potassium ducts is a fairly common problem that many people face.

To determine the need to replace a strap with number 21100370172000 or any other, you need to take into account the signs of wear on the part, more about them:

There is a whistling noise while driving. As practice shows, the appearance of a whistle is often associated with the switching on of many energy consumers, that is, if there is a high load on the on-board network. For example, you started the engine of your Kalina, and when you step on the gas, a loud whistle starts to be heard from under the hood. In most cases, this is due to the fact that the belt is loose - then it will need to be tightened using a tension roller, or changed if its condition requires it.
The device itself began to show signs of cracks and other damage or deformation. By opening the hood and looking at the strap, you may find signs of damage on the structure of the strap, this indicates wear. In this case, the problem will not be solved by tightening or adjusting the tensioners; the problem of wear can be solved exclusively by replacement.
When the power unit was operating, noise began to appear. In the event that the service life of the belt is coming to an end, this can be recognized by uncharacteristic noise from under the hood, which was not there before. For example, many car enthusiasts also note that in addition to noise, there is also a loud knock, as well as knocks when the car engine is running (the author of the video is Ilgiz Magafurov).

If the car has a special generator device sensor that allows you to determine whether it is operating correctly, then it will be much easier to determine the problem. For example, if a whistle appeared from the engine compartment and a light began to light on the sensor, this indicates that the belt needs diagnostics. Such a strap should be tightened, since the whistle, as mentioned above, indicates a weak tension, and such a problem may also indicate the need for replacement.

Video “Replacing the belt on Lada Kalina”

The author Kalinin talks about the procedure for replacing the belt on his Kalina with a tensioner.

The generator is used to generate electricity, which powers the entire on-board network in a moving car, including the Lada Kalina. This implies the need for uninterrupted operation of this node. The battery is also recharged through the generator set. The Lada Kalina generator is driven by a belt that requires proper tension.

Operation implies the presence of situations in which the generator belt tensioner ceases to correspond to the required optimal value. This inevitably provokes interruptions in power generation. In the modern domestic model Lada Kalina, among the most common reasons causing disturbances in this system, there is a malfunction of such a part as the generator belt tensioner (roller). It is this important element of the practical Lada Kalina that will be discussed further.

Lada Kalina: alternator belt tensioner, check and replacement

As you know, the Lada Kalina generator belt (belt of attached units) gradually wears out, stretches, etc. during the operation of the car.
For this reason, you should constantly check the tension of the generator belt, and also assess the condition of this element for delamination, cracks and other defects. It often happens that the belt itself is in good condition, without obvious defects. However, it cannot be tensioned due to the fact that the Kalina belt tensioner has failed. Next, we will look at how to replace the alternator belt on Kalina with your own hands, as well as how to change the Kalina tension roller.

How does the tensioner work and what is the principle of its operation?

Only at a certain level of tension in the belt drive does optimal operation of the generator occur, which allows the supply voltage to be sent to the on-board network with maximum efficiency, otherwise tension is required. The generator belt tensioner we are considering is used for these purposes. Structurally, this is an ordinary bearing, the upper part of which is protected with a plastic coating. The belt moves along the working surface of this roller. The internal race of the tensioner is presented in the form of a conventional landing sleeve. Its tension must be certain.

Types of rollers according to design principle:

Eccentric type. This option is the simplest product, whose design is very ordinary and endowed with enviable reliability. The part includes a bearing, bushing and protective pad.
Bracket view. Here the adjustment process is carried out by moving the tensioner bracket present on the motor. The tensioner bracket is not difficult to find.

Signs of breakdown and vulnerable spots

In any tension roller design, the weakest point is the bearing. The part is subject to loads of a constant nature, in addition to which temperature differences contribute. Under such conditions, element failure can occur quite often.

Let's take a closer look at the list of main signs, due to the presence of which the roller can be considered faulty:

The battery no longer receives a full charge;
the car's energy-intensive current collectors began to show disturbances in their functioning;
a characteristic hum coming from the area where the generator unit is located;
presence of play during roller operation;
The working surface of the generator set drive belt shows signs of uneven wear.

Fault diagnosis methods

When checking the correct operation of the tension device in the Lada Kalina, it is recommended to follow the following algorithm of actions:

First, we carry out visual observation of the belt and the roller itself. To do this, you need to open the hood and start the LADA Kalina engine. When inspecting rotating components, we evaluate them for the presence of vibration.
We control the tension force of the belt drive. To do this, stop the engine. We take hold of the belt branch with our hand and try to rotate it 90 degrees relative to the longitudinal axis. Rotate clockwise. If this manipulation is successful, then the tension is correct. When the angle obtained as a result of turning the branch is different from the indicated optimal value, further adjustment is required.
Now you need to check the tensioner itself. To do this, you need to remove the belt. Before direct dismantling, remember the original location of the consumable element. Loosen the adjusting nut on the roller, after which the belt can be easily removed. We scroll through the video and observe the absence of jamming and noise. We inspect the protective cover and check for the presence of play. We pay special attention to the working surface, which comes into direct contact with the belt. It should be smooth, and the presence of deep ditches or other damage is unacceptable. If any of the indicated signs occur, then such a tensioner must be unconditionally replaced.

How to replace the Kalina generator roller?

Here we need the following tools:

a screwdriver with a flat tip;
keys whose standard sizes are: “8”, “19”, “17” and “13”;
awl.

Process.

How to tension the alternator belt correctly step by step:

First, by opening the hood of the LADA Kalina, we loosen the tension of the belt drive.
Now we use a wrench set to “19”, with which we loosen the tightening torque of the nut. Rotate the rod in a clockwise direction until it comes completely out of the seat.
Next, use an awl to pry up and remove the plastic protective cap present on the roller. A screwdriver with a thin and flat “tip” may be suitable for this purpose.
We find a bolt that secures the bearing to the bracket. To do this, we “arm ourselves” with the key to “17”.
Now carefully remove the roller. It comes with a protective washer and bushing.

Replacing the alternator belt tensioner pulley

Problems with the generator can lead to more serious problems. If electric current is not generated by the car, if it runs on one battery, then battery failure is also inevitable. If there is insufficient production of on-board current, as indicated by the corresponding light on the instrument panel, first of all, it is necessary to check the tension of the alternator belt.

In addition, in many cars, the belt drive we are talking about, which, by the way, is driven by a timing pulley, often connects other critical components. These units are also called attachments. In particular, the belt can drive a pump that pumps antifreeze. So loosening the belt can lead to more than just power problems!

It is regulated by a special roller, which is located on the tensioner bracket. If this wheel rotates noisily, sticks, or releases grease from the cuff, the defective alternator belt tensioner roller needs to be replaced. Why does this small critical element fail and how to change it? Let's first consider the example of Kalina. The reasons for part failures are simple.

Wear due to end of life.
Violation of the integrity of the cuff.
Manufacturing defects.

To replace the belt tensioner roller of the Kalinovsky generator, we will need the following tools:

In principle, the procedure for replacing the tensioner belt roller of the Kalina generator is easy to learn from a video on the Internet. But we will also provide fairly clear instructions.

Find the hexagon of the adjusting pin above the pulleys and place a 8mm wrench on it.
Having loosened the locknut with a 19mm wrench, we rotate the pin clockwise, so our treasured part will move away from the belt.
Use a screwdriver to remove the roller cover.
Unscrew the roller mounting bolt with a size 17 wrench.
We remove the roller assembly with bolt, bushing and washer.
With the new part, we assemble everything in the reverse order.

From these instructions it is easy to understand that replacing the generator belt tensioner pulley in Kalina is a fairly simple process.

Let's sum it up

This completes the dismantling procedure. Now you know how to tension the alternator belt. The steps for reinstallation are also very simple, so there is no particular need to comment on them. Upon completion of the entire list of installation procedures, we check the tension level for compliance with the specified requirements. We start the engine and observe the operation of the unit. If no side factors are detected, then the work was done correctly.

Also in LADA Kalina it is possible to remake the tensioning device, which is confirmed by this video:
