Print this article Font size 16

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, 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.

What affects service life

There is no clear answer regarding the frequency of replacing the input shaft bearing. Therefore, the procedure is carried out depending on the current condition. The wear rate of elements is influenced by several factors, including:

• The quality of the bearings used;
• Driving style;
• Conditions under which the vehicle is operated (weather, road quality);
• Frequency of visits to car repair shops or self-diagnosis of the car’s condition, etc.

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.

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.

POSSIBLE FAULTS

Despite the imperfect operation, the VAZ 2114 gearbox, when used correctly, is distinguished by good endurance and durability. If you do not hesitate to prevent and promptly eliminate breakdowns, repairing it is not expensive.

Let's consider the main gearbox malfunctions that the owner of the fourteenth may encounter:

1. Lack of speed fixation when switching. If the speeds are out of whack, the cause is most likely worn teeth on the gears and clutch. Accelerated wear of these parts is caused by incorrect gear shifting and non-compliance with the speed limit. The problem is resolved by replacing the gears.
2. The gear shift lever is tight. The reasons are mechanical damage to the teeth of the lever fixing on the hinge or wear of the reaction rod; it’s also a good idea to check the integrity of the plastic parts of the gearbox drive;
3. The VAZ 2114 gearbox is humming. Most often, the gearbox is humming in neutral gear. First of all, you need to check and, if necessary, add oil (in general, the box may hum due to the use of low-quality lubricants). If the oil is normal, the problem is wear of the bearing on the input shaft, which can only be determined through diagnostics or by disassembling the gearbox;
4. Crunching sound when changing speed. Here it is necessary to change the worn out synchronizer, and it must be changed immediately after the problem has been discovered, because if you tighten it, the gear unit will completely fly off;
5. Knock. The gearbox on a VAZ 2114 can knock both under load and without it, and in any gear. The cause of the knocking noise is a damaged drive gear of the problematic transmission.

One of the key factors for the trouble-free operation of gearbox number fourteen is the use of high-quality lubricants. The most suitable option is GL-4 mineral oil. It is not cheap, but it does its job at 5+; when using mineral oil, VAZ gearbox repairs are usually required extremely rarely.

Most VAZ 2114 owners agree that the best gearbox oil is 75W90. It is distinguished by greater fluidity than typical gearbox oils, due to which the lubricant better gets into those places of the gearbox, the lubrication of which is provided exclusively by splashing. Good options for 75W90 are Hypoid-Getriebeoil TDL and Liqui Moly Vollsynthetisches Getriebeoil (GL-5).

Checking the oil level should be carried out every three weeks. In the gearbox, the fourteenth gear is placed vertically, the topmost is the fifth, it is the one that is most susceptible to failure due to lack of lubrication, so it is always necessary to fill in oil to the maximum mark, and best of all - 200-250 ml. more than the required norm.

Replacement

Many people turn to a service station to replace this bearing. It is noteworthy that car services often refuse to perform such work. It’s understandable, because the procedure is painstaking, and you can’t get a lot of money for it.

Dismantling works

To do the job yourself, follow the instructions.

1. You can often find advice about the need to completely disassemble the gearbox to replace the bearing. But this is optional. You can do without such complex manipulations.
2. In any case, you will have to remove the box, so familiarize yourself with this procedure.
3. Before removing the gearbox, remove the negative terminal from the car battery.
4. All the chips are removed from the box, the wire from the speedometer is unscrewed.
5. Next, the trousers of the vehicle exhaust system are dismantled.
6. After this, you can completely remove the gearbox.
7. At the next stage, the bell is dismantled. You can try to do without it, but then it will definitely constantly interfere with your work.
8. Thoroughly clean the box from accumulated dirt.
9. The bearing is secured using retaining rings. To remove them you will need a flathead screwdriver.
10. The rings are pryed off and loosened a little, after which there will be no more problems with removal.

1. To make it more convenient, arm yourself with tweezers that can be used to remove the ring.
2. Using a flat-head screwdriver, pry the bearing by the ring groove, and at the same time move the input shaft slightly forward.
3. Insert a pry bar between the gearbox and the bearing. It is unlikely that you will be able to do this without an assistant.
4. You will operate the tools, while your friend will hold the pry bar.
5. Your main task is to press out the bearing. To do this, precise, strong, but most accurate blows are applied to the input shaft.
6. In the process of striking, the shaft must rotate.
7. This work will take you about 20 minutes. But if you have a special puller at your disposal, you can speed up the work. Although it is really convenient to work with a puller only if you decide to disassemble the gearbox.
8. Before installing a new input shaft bearing, be sure to lubricate the element with regular engine oil.
9. Carefully press the component into place using gentle, light blows with a hammer. It is better to use a pipe of diameter or a stand.
10. When pressing, apply blows to the inner race, in a circle, as evenly as possible.
11. Once the bearing is pressed in, make sure it is seated properly. Scrolling should be calm, without obstacles.
12. Reassemble the box in reverse order and install it on the car.

Do-it-yourself repair of VAZ 2108-099, 2110-2112, 2113-2115 gearboxes for the first time (brief instructions)

Problems with the gearbox began last summer, the 2nd speed was difficult to engage, in the spring the gear selector rod seal leaked, then the 3rd speed finally began to crunch when turned on. But the real juice was when you urgently need to go somewhere, and the reverse speed is not ALE!, and when you can go slowly, then with the reverse - everything is fine! Since I do the repairs myself, I decided to do everything myself this time (in the sense of not contacting service stations and other garage technicians), it’s not all that difficult))) We remove and disassemble the box (there are plenty of video instructions on the Internet)

If you take it apart, you need to change all the consumables at once, so you don’t have to go through it again later.

We press out all the bearings and seals from the gearbox housings, remove the satellites, disassemble the secondary shaft, in short, throw everything into the trash. We carry out troubleshooting and find the reasons why our gearbox did not want to work properly. We take old spare parts with us as an example, because VAZs also had parts of different sizes. Don’t forget to take a friend with you and let’s go with him for new parts. We buy everything we need and don’t need, spend all the money we had in our pocket, borrow money from a friend and spend it too. Satisfied, we go to the garage.

What was purchased and replaced:

1. Front bearing of the input shaft 6-42205 A1E1USH1 2. Front bearing of the secondary shaft 6-42305 A1E1USH1 3. Rear bearing of the primary and secondary shaft 4. Differential bearings 5.

replacing the input shaft bearing of a VAZ 2114

Many owners of VAZ cars have encountered an unpleasant noise that comes from the gearbox when the clutch pedal is released. Often this sound indicates critical wear of the input shaft bearing. In our article we want to talk about how to replace the VAZ 2109 input shaft bearing without disassembling the gearbox itself. Of course, the gearbox of a VAZ car will have to be removed from the car in any case, but even a novice car enthusiast can handle this process.

But you won’t have to disassemble the box to replace the input shaft bearing, and this is the main advantage of this method, since only an experienced repairman can sort through the box. So, after dismantling the gearbox from the car, it is necessary to remove the bell and retaining rings. Next, you need to take a powerful flat-head screwdriver and pick up the bearing by its annular groove. Using the intermediate shaft bearing as a kind of support, we try to move the input shaft forward. Then we take a medium hammer and carefully hit the end of the input shaft.

We turn the shaft a little and continue striking. Depending on the tension in the shaft-bearing engagement, blows will need to be applied for from two to twenty minutes. As a result of these actions, the worn bearing will come off the input shaft. After this, you can press the new bearing onto the shaft. This is done by lightly hitting the inner ring of the new bearing with a small hammer. That's the whole procedure. As you can see, there is no need to disassemble the gearbox to replace the bearing.

Disassembling the VAZ 2115 gearbox

Wash the gearbox, preventing water from entering the crankcase, and place it on a disassembly stand. Remove the power unit suspension bracket and the clutch release cable mounting bracket.

Remove the primary and secondary shafts at the same time (

Unscrew the gear selector mounting bolts (

If it is necessary to disassemble the secondary shaft, clamp it in a vice with soft pads and use a universal puller to press the ball bearing from the shaft. The bearing is pressed off the input shaft in the same way. Then remove the driven gears of IV, III, II and I gears and synchronizers assemblies from the secondary shaft in the order indicated on

– if it is necessary to replace the driven gear, unscrew the bolts securing it and compress gear 7 (

If necessary, disassemble the gear selection mechanism by unscrewing the nut securing axle 6 (Fig. 3.16) of the gear selection lever and remove the retaining rings from the reverse fork axle and from the axle 7 of the locking brackets, remove the reverse fork 8, gear selection lever 4 assembly with a locking bracket 5, a lever axis 6 and a spring 11 with a thrust washer 10.

If necessary, remove the speedometer drive by unscrewing the nut securing it and, supporting the driven gear shaft, remove the speedometer drive.

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.

Causes of wear

Replacing the VAZ 2110 input shaft bearing

You can find out about wear and when it is necessary to replace the bearings of the primary shafts of gearboxes based on such signs.

• in neutral gear, with the engine running, extraneous noise may be heard;
• When the car is moving in any gear, you can hear a knock in the gearbox;
• transmissions may switch off spontaneously;
• the clutch may not disengage (this often occurs due to jamming of the bearing);
• If the bearing is misaligned, the clutch disc may be destroyed.

Note! If you do not pay attention to the above listed signs of malfunction of this part, in the future you will not be able to do without severe repairs of the clutch or gearbox. By changing the gearbox shaft bearings in a timely manner, it is possible to avoid unnecessary problems and additional foreign exchange costs for repairs.

11. Unscrew the speedometer cable, remove the boot, and the reverse speed sensor wire.
12. Remove the driveshaft.
13. Unscrew the traverse while holding the gearbox.
14. Unscrew and pull out the gearbox.

Where is the bearing located and how to remove it

On VAZ cars, the bearing is located on the secondary shaft behind the oil seal. Remove the bell and retaining rings from the dismantled gearbox; there is no need to disassemble it further. To remove the bearing itself you need to:

1. Using a strong screwdriver (serious efforts will be required, therefore the screwdriver must be powerful so as not to break) hook the bearing by the ring groove.

2. Push the transmission input shaft forward, using the shaft bearing as support.

3. Slowly pull the bearing off the input shaft by tapping it with a hammer. The process of knocking out the bearing can take from five minutes to half an hour.

Rules for installing a new input shaft bearing

The new bearing is installed on the input shaft by pressing. It is pressed in using a light hammer. It is necessary to apply them carefully and evenly on the inner ring of the bearing, while pulling the input shaft forward. After replacing the input shaft bearing has been successfully completed, you need to reinstall the gearbox, and this is done in reverse order.
