Many people replace the input shaft bearing themselves, without the help of specialists from a service station. To perform such work, you need to know the location of the element you are looking for and the signs of its malfunction. Plus we will tell you in detail how you can understand this bearing.

Element appearance

Location

Since we are talking about the VAZ 2114, we will first determine the location of the element.

On the fourteenth, the primary bearing is located on the shaft behind the oil seal.

It is noticeable that on some boxes this bearing additionally plays the role of an oil seal, taking on the load together with the release bearing.

To get to the damaged gearbox component, you will have to remove the gearbox. Quick replacement of the VAZ gearbox input shaft bearing. When choosing a new element, be sure to check the advice from the operation department of your VAZ 2114 regarding the overall dimensions of the component.

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.

Signs of failure

All bearings, of which there are many in a car, have approximately the same signs of failure. But since you understand the location of the input shaft bearing , finding that problems appeared specifically with it will not be so difficult.

There are several corresponding signs of its failure.

Before the car is sold, you can drive, but the clutch can growl.

It is better to fill in good oil and do it as early as possible. Ideally, after purchasing, drive 1000 km, if it’s not winter outside, and change it!

Does not help. Oil will not save you from chronic illness. If it is noisy, then only replacement will help. I had an experience when a car (8) went about 200 thousand without changing the gearbox oil and the bearing did not make any noise. Engine oil was added at the factory. And now the Castrol transmission has been noisy since new

When do you need to change the gearbox input shaft bearing?

Replacing the input shaft bearing on a VAZ 2110

Surely, many car enthusiasts are asking the question “when do you need to change bearings?” In fact, there is no definite answer, since the resource of this mechanism directly depends on:

bearing quality;
vehicle operating conditions;
driving style;
regularity of technical inspection.

Typically, problems that occur due to a worn bearing are detected during the next technical inspection. Diagnostics of the gearbox can be carried out in specialized technical centers, and it becomes possible to evaluate the resource of the components of the unit that remains. The same applies to PV bearings. In certain situations, you can get by with simply lubricating the bearing. Such measures will help normalize operation and eliminate noise in the gearbox. When undergoing vehicle maintenance, experts strongly recommend doing a clutch diagnostic (see: Repairing the VAZ 2110 clutch - we do it ourselves).

Location

Since we are talking about the VAZ 2114, the first thing we will do is determine the location of the element.

On the fourteenth, the primary bearing is located on the shaft behind the oil seal.

It is noteworthy that on some gearboxes this bearing additionally plays the role of an oil seal, taking on the load together with the release bearing.

To get to the damaged transmission component, you will have to remove the transmission. When choosing a new element, be sure to check the recommendations from the instruction manual for your VAZ 2114 regarding the overall dimensions of the component.

Which wheel bearing to choose for replacement

The front wheel bearing is of both domestic and foreign production. As they say, there will be something to find for such a car. But it’s better not to buy Chinese spare parts to replace the front wheel bearing on a VAZ 2114. They are inexpensive, but hence the quality is not very good, and you won’t go far with them.

Which wheel bearing to choose for replacement

It is better to pay attention to imported spare parts, especially from Europe. Although they are more expensive, their quality speaks for itself. When purchasing, be careful not to confuse them with Chinese counterfeits, there are many of them now.

It is also worth looking at domestic manufacturers, such as those from Vologda or Samara. Excellent quality at a reasonable price. They also include instructions for installing the bearing, which makes the task even easier.

How to buy original bearings

In order to distinguish an original bearing from a fake, look at the box; it must have proper presentation. The rotation of the bearing is tight, but the fake bearing rotates very easily, no effort is required. The inner holder of the original has all the necessary numbers and inscriptions. But on fakes they are located both inside and outside. The differences between them are minimal, there may be a different brightness of color on the bearing, or a slight difference in shape.

Signs of failure

All bearings, of which there are quite a few in a car, have approximately the same signs of failure. But since you know the location of the input shaft bearing, it will not be so difficult to determine that the problem arose with it.

There are several characteristic signs of its breakdown.

Sign

Peculiarities

Howling when the clutch is released in a parking lot

The element has failed and needs to be replaced. The howling is usually caused by the formation of chips, cracks, or the destruction of 1-2 rollers

Whistle when driving

The bearing is partially damaged or there is no lubrication. The problem in the absence of lubrication can only be determined by dismantling and visual inspection. To solve the problem, sometimes it is enough to simply lubricate the element and return it to its place

Clutch won't engage or disengage

Most likely the bearing is stuck. If the damage is serious, the input shaft may need to be replaced.

Knock in the area where the element is located

The bearing knocks only when the part is completely destroyed. If you do not replace it in time, the bearing will be welded to the shaft, so you will also have to replace the shaft itself

If you notice the first signs of a malfunction of the input shaft bearing on your gearbox, you should immediately check the condition of the element and, if necessary, replace it.

Transmission device diagram

The gearbox mechanism is a system of parts that has an independent structure and characteristic features determined by the model. Before you begin repairing the gearbox, you must familiarize yourself with the diagram of the transmission mechanism in the operating manual. The diagram contains the names of the parts and the structure of the relationship.

Transmission device: 1 - input shaft; 2 - secondary shaft; 3 — rod for shifting the third and fourth gears; 4 — fork for shifting third and fourth gears; 5 — differential; 6 — fork for switching first and second gears; 7 — fork rod for shifting first and second gears; 8 — gear shift rod; 9 — fifth gear shift fork rod; 10 — gear shift mechanism; 11 — reverse intermediate gear; 12 — clutch housing

Knowledge of the structure of the structure reduces the time spent on identifying mounting fasteners and dismantling components.

Dismantling

You will need help to complete the next steps. To press out the required part, you need to insert a pry bar between the bearing and the gearbox. One person should hold the pry bar and the other should strike the input shaft. The blows must be precise and strong, and in the process of applying them the shaft must be rotated. It may take more than a quarter of an hour to complete the job.

A special puller will allow you to avoid such a complex procedure. But in order to use this device, you will need to dismantle and completely disassemble the gearbox.
