Replacing the gearbox seal on a VAZ-2110 (+ signs of wear)

An oil leak from a VAZ-2110 car is a serious cause for concern. It is especially dangerous when oil begins to leak from the gearbox. As a rule, this problem is associated with wear of the rocker seal. If this problem is discovered, repair work must be carried out immediately.

Two ways to replace the gearbox seal on a VAZ-2110

It is easier to change the oil seal with the gearbox removed.

Replacing an element that has become unusable can be done in two ways.

The first of them is very labor-intensive , since it will be necessary to remove the gearbox. But replacing the oil seal will be much easier.
The second method seems less time-consuming and labor-intensive , but in practice it is very difficult to carry out this procedure. Only experienced motorists who have repeatedly had to repair their cars can replace the oil seal directly on the car without removing the gearbox.

Troubleshooting

Experienced car owners know the visual reasons why they can determine the failure of the rocker seal. Naturally, for such reasons it is impossible to accurately determine the cause of the leak, but this gives a signal to carry out diagnostics, in which the cause of the oil leak can be accurately identified.

The most important sign is oil stains under the car, especially in the gearbox area.

An oily rubber boot indicates a malfunction of the rocker seal.

But these spots do not always indicate oil seal failure. It happens that this is due to the oil filter, which sometimes does not tighten properly. In any case, the driver is obliged to monitor for any oil leaks in the checkpoint area . To do this, you need to monitor the oil level. This is the only way to save the box from damage, which will certainly happen if it operates with a minimum amount of oil.

Another way that indicates the oil seal is worn out is a characteristic crunch that is heard when changing gears . But only an experienced VAZ-2110 owner can diagnose this crunch. In any case, if you hear unusual sounds when shifting into gear, it is better to diagnose the gearbox.

Set of tools required for replacement

A minimum set of tools for replacing the oil seal without removing the gearbox.

In order for the replacement of a part to take place without problems, you need to prepare the place and the necessary set of tools in advance. You will need:

A set of keys and sockets, and for 13 you need two keys and there must be a key for 10. There must also be a socket head for 22.
A chisel or screwdriver will be needed to knock out the oil seal.
The hammer is small so you can get under it.
Silicone sealant.
Awl and hook.

Additional accessories

A regular self-tapping screw will allow you to do without a special puller.

For those who decide to replace the gearbox seal without removing it from the car, you will need additional equipment:

Several long screws.
A piece of pipe for pressing in a new oil seal.

It should be noted that the replacement process without removing the gearbox is much more complicated. In addition, there is a possibility of damaging the part being replaced during pressing.

What parts to choose for replacement

It is better to immediately change the boot along with the oil seal.

Before you begin repair work, you need to purchase the necessary parts for replacement.

As for the oil seal, Balakovo products are very popular. You need an oil seal with article number 2110–1701043 and 21100-1701043-00 .

Manufacturers offer two options for oil seals - simple and reinforced.

In addition, it is recommended to immediately purchase a cardan boot, as there is a high probability that it is also worn out. Even if this is not the case, it may break during the repair process. Therefore, it is better to spend a small amount on anther than to bother with disassembly again.

Recently, reinforced oil seals have appeared on sale, which are called that way. If you believe the assurances of sellers, their service life is significantly higher than that of standard products.

Process in detail (algorithm)

It is recommended to carry out replacement work in a pit. In this case, you must take care of safety. The car must be secured using a handbrake and wheel chocks, which must be installed on both sides of the rear wheels.

Having prepared a workplace and a set of tools, you can begin to work. To replace the gearbox seal, you need to do the following:

Most often, the VAZ-2110 wing is closed with a rubber boot. If this part is covered in oil, this immediately indicates that the oil seal is really worn out. The boot needs to be bent. To do this, you just need to pull it by the wide part.

Oil leaking from under the “glass” - the rocker seal definitely needs to be changed.

Before loosening the clamp, you need to put a mark so that you don’t have to adjust the link later.

The oil seal is located deep in the bushing.

Only after this you need to press the new part into the rod. This procedure is quite complicated, since there should be no distortions. Many drivers use various homemade devices when pressing. When working, it is very important not to damage the new part, otherwise everything will have to be redone.

After the spare part is in its place, assembly is carried out in strictly the reverse order.

Conclusions (video)

If you are not confident in your abilities, you can watch a video that shows the entire replacement process in detail. Self-repair will guarantee that everything will be done efficiently, since the owner of the VAZ-2110 will control the process.

Replacing the backstage seals of a VAZ 2110

First you need to arm yourself with the necessary set of tools, which includes:

Set of keys (10, 13);
An ordinary awl or other sharp metal object;
Screwdriver;
Hook;
Plastic stopper.

The oil seal must be replaced in a viewing pit or overpass. If this is not possible, then an option with a lift will do. In addition, there is another option, which involves placing two spare tires flat under the car, like stops. Two strong boards are placed on them, and the car drives onto a makeshift overpass. Simple and brilliant.

Advice. If a motorist drives into a hole or other device, he must take care of the safety rules. In particular, it is necessary to secure the vehicle using the parking brake and wheel chocks.

Replacing the gearbox seal of a VAZ 2110

Let's start the replacement process:

The slide on a vase is almost always covered with a special rubber boot. If the cuff is faulty, then this same boot will be covered in oil, which will once again indicate the need for replacement;
We take the wide part of the anther and bend it;
We see the cardan located at the bottom;
We disconnect this same cardan from the rod and lever, thus gaining access to the cuff (we use a 13 key in our work);
The nut is turned out completely, which allows you to loosen the connection between the cardan and the lever;
The lever is removed from the cardan;
First or third gear is engaged;
The cardan is completely disconnected from the rocker;
The cardan is removed;
Now you should remove the rubber boot.

Replacing the rocker seal on a VAZ 2110 gearbox

We see the cuff itself, which is located in a certain recess. This is where the rocker seal fits into the gearbox and needs to be removed from this recess.

Note. It is almost impossible to remove the cuff from the rod without using a special tool. An awl and a special hook will help in the work.

We insert the awl and the hook inside and thus remove the cuff (you can also use a self-tapping screw, which we screw inward, thereby uncorking the seal, like a corkscrew);

After removing the old cuff, you should begin replacing:

We clean the place where the new cuff will be placed;
We press the new cuff inside the rod.

Advice. It is easier to replace the seal using a stopper from any plastic bottle. The new oil seal is inserted into the inside of the plug, which is cut out in advance. And then it is pressed in.

Assembly is carried out in reverse order.

That's all. As you can see, the instructions are not complicated at all and you can easily do everything yourself. During the work process, you can watch a useful video or study photo materials. This way you can save a lot of money. And why overpay if the price for repairs at a service station is not low today.

Replacing the spring. It costs pennies, so this option seems very tempting. However, experienced VAZ 2109 owners do not advise agreeing to it: the majority of the parts are made of overheated metal and break very quickly. And you will have to pay again for disassembling and repairing the gearbox;
Replacement of the gear selection mechanism as a whole. It will cost 1000 rubles. or a little more (of course, plus the work of a mechanic), but you will forget about the troubles it causes, if not forever, then for a long time.

When and how to replace the oil seal on a VAZ 2110 gearbox?

The VAZ 2110 gearbox is manual. To extend its service life, it is advisable to use original transmission oils. It should be noted that the VAZ 2110 is equipped with injection engines.

When does it become necessary to replace the VAZ 2110 gearbox oil seal?

The VAZ 2110 transmission system includes reliable components that, when interacting, ensure smooth running and decent power performance of the vehicle. Among the consumables that periodically have to be changed on a car are oil seals. These components are located on the front wheel drives and the gearbox input shaft. Among the reasons for their deformation are:

natural wear and tear;
factory defect of the product;
mechanical damage as a result of external influence.

The result of this is an oil leak from the gearbox. The failure of a spare part can be indicated by the presence of an oil slick under the car or the appearance of a characteristic crunch when changing gears. An independent inspection often reveals fuel leaks at the junction of the gearbox and the power unit. In case of these manifestations, vehicles must be sent for diagnostics.

What tools are needed to replace consumables? To carry out this procedure, you need a set of keys and heads, a chisel (punch punch), and a hammer. The sooner a breakdown is detected, the less damage will be caused to the automotive system.

How to replace the gearbox drive oil seal, the input shaft of the VAZ 2110 gearbox?

When servicing a car's gearbox, the driver often needs to change the rod seals along with the seals on the manual transmission. If these elements have lost their physical properties, then the owner of the VAZ 2110 will face a problem such as oil leakage in the gearbox. To fix the problem, you need to replace the seals, seals and sealants.

The drive seal (left or right) is changed as follows:

The driver must provide access to the checkpoint.
It is necessary to drain the transmission oil from the car into a previously prepared container.
The drive is removed.
The old oil seal is removed and a new one is installed.

In this case, there is no need to disassemble or remove the gearbox from its original location.

Important! When installing a new oil seal, it is necessary to lubricate it and use a special seal.

Removal of the gearbox is required if the input shaft oil seal is worn out. This accessory part changes as follows:

Removing clutch parts from the housing.
Using a special tool, you must carefully pierce the oil seal.
To remove the oil seal, use pliers.
A new part is being installed.

How often do you have to replace? This indicator is influenced by driving style. On average, a spare part is replaced every three years. As a rule, after replacing this component, the car restores its driving properties.

Thus, it is possible to replace the oil seal on a VAZ 2110 gearbox yourself using special tools. This transmission consumable cannot be restored. Its price remains affordable. To keep vehicles in working condition, it is worth undergoing maintenance every 15,000 km.

Causes of manual transmission oil seal malfunction

If there are obvious signs of oil leakage on the gearbox, then the oil seal has stopped performing its functions. Frequent causes of malfunction:

Natural wear and tear over a long service life. Nowadays, manufacturers care about the durability of parts, but sooner or later even the most durable materials become unusable. If we talk about seals, then under the influence of high temperatures and oil, rubber cracks and dries out;
Mechanical damage is often associated with road traffic accidents or poor quality repairs;
Deformation;
Use of non-original oil seals made from low quality materials.

We recommend: Vehicle design. Everything about the car

To replace the old seal with a new one, you need to understand the causes of the failure. If the reasons are not found and corrected, there is a high probability that the new part will also quickly break.

Replacing gearbox seals for VAZ 2109, VAZ 2114 and VAZ 2110

Hello, reader of the blog RtiIvaz.ru. Today we will study how to replace gearbox seals on a VAZ 2109, VAZ 2114 and VAZ 2110. Replacing gearbox seals on a VAZ 2109, VAZ 2114 and VAZ 2110 and on other Lada models is done when oil leaks are detected. Typically, drips occur in the places where they are installed and a sign is a decrease in the oil level in the gearbox.

Sometimes oil leaks appear at the junction of the gearbox and engine. In this case, you need to touch the leak with your finger and by the smell you can determine where the oil is coming from. From the engine or gearbox. Transmission oil has its own specific smell, which differs from engine oil.

Before replacing the gearbox seals, you need to drain the oil from the gearbox. To do this, we need a container for the drained oil and two keys for 17 and 13. First of all, we need to check the gearbox breather, which is designed to ventilate the gearbox. And in the absence of one, excess pressure develops in the crankcase and this can cause oil to be squeezed out through the cuffs.

Transmission seals for VAZ 2109, 2110, 2112, 2114 cars are usually sold in a set of 4 pieces:

Primary shaft oil seal.
Drive seals, there are two of them, left and right, we will look at the differences later.
Gear selector rod seal.

REPLACING THE INPUT SHAFT SEAL

To replace the gearbox seals, especially the input shaft, the gearbox must be removed from the engine. Having removed the gearbox, carefully inspect the installation locations of the cuffs. And first of all, you need to dismantle the release bearing and remove its guide. Under it you will find the input shaft oil seal.

To remove the seals we need a flat-head screwdriver. By prying it from the inside, you can remove the cuff from its seat. The input shaft oil seal has dimensions 25x45x9. Catalog number 2110-2301043Р. It is better to install it with sealant. The outer race of the oil seal must first be degreased, and then a thin layer of sealant must be applied.

When installing, you must ensure that the inner race of the oil seal does not turn outward and the cuff spring does not jump out of its place. We install it in its place and carefully, using a pipe, lightly tapping, hammer the cuff into place. In this case, it is necessary to ensure that the plane of the input shaft oil seal lies exactly in relation to its seat.

Then we install the release bearing guide in place. It is secured with three bolts, which should be tightened evenly so that it fits into place without distortion.

Next, we immediately install the release bearing. When installing it, you must immediately put on the wire springs, which are placed on the legs of the release bearing and fix it in place.

Now it's time for the drive seals. There are two of these seals, the left one is red and the right one is black. They also differ in the direction of rotation. This direction is shown by arrows on the seal housing. These arrows are located on the inside of the oil seals, on the right oil seal the arrow points to the left, and on the left oil seal the arrow points to the right. This can also be determined by the oil removal notches applied to the inside of the cuff.

They act to deflect oil away from the cuff. They are applied at opposite angles, in the direction of shaft rotation. Typically, the manufacturer labels it in three ways:

Catalog numbers. The number of the right oil seal ends in an even number 2110-2301034Р, and the number of the left one ends in an odd number 2110-2301035Р.
Arrows, left arrow on the right, right arrow on the left.
Color. The left one is red. The right one is black.

Causes of clutch oiling

The reason for oily clutch is a leak of the crankshaft rear oil seal or the gearbox input shaft oil seal. Transmission and engine oils have different smells. Therefore, an experienced car enthusiast can recognize by the smell of oil which of the seals has failed and requires replacement. In this case, you will have to remove the gearbox from the car.

Replacing the input shaft oil seal

So:

To remove the box, remove the CV joints as described above.
Instead of one of the CV joints, we insert an old one or a special plug to prevent the differential from falling apart.
We unscrew the fastening bolts (there are three of them) and remove the clutch housing shield.
Loosen the bolts and nuts securing the clutch housing to the block.
We place suitable wooden blocks located in the area of the strut supports on the wing flanges and install a cross beam on them to hang the engine.

We attach the engine to the beam using a long bolt with a hook.
A strong rope or wire is also suitable for this.

Unscrew the two nuts securing the rear engine mount to the body.
Unscrew the nut and take out the left support bolt.
Unscrew the three nuts securing the left engine mount to the gearbox and remove the mount.

We finally unscrew the bolts (three pieces) and the nut (on the back of the gearbox).
When removing the gearbox from a VAZ 2109, we first move it horizontally away from the engine to remove the input shaft from the clutch discs.
Be careful not to damage the clutch spring petals.
Remove the clutch release bearing.
We unscrew the three bolts securing the guide bushing (there are spring washers under the bolts).
Remove the guide sleeve.

Using a suitable wire hook, remove the oil seal from the gearbox.
We press in a new one using a mandrel of suitable diameter.
The working edge is directed inside the gearbox.

We install a gearbox on the car.
Before attaching the front wheel drives, we replace the retaining rings at the ends of the inner CV joints.
Otherwise, there is a possibility that the drives will jump out of the gearbox when the vehicle is moving.
We finally tighten the nut that secures the brace to the lever on the loaded suspension while the car is already on the ground.
Change the oil in the box (see).

This is how oil seals are replaced, there is nothing super complicated about it, in addition you can watch the video.

It is noteworthy that on the VAZ 2110 the rocker seal must be replaced when there is an oil leak from the gearbox. Replacing the VAZ 2110 rocker seal can be done in two ways, which will be discussed in this article. One of the ways to replace the cuff cuff involves dismantling the gearbox. The second method is not so cumbersome and is carried out directly on the car without removing the box. Needless to say, this method requires knowledge of certain secrets and skills.
