Input shaft bearing on VAZ 2114: do-it-yourself replacement, fault diagnosis

Bearings for vaz boxes

The gearbox of a VAZ 2110 car contains several bearings. These parts are very reliable, but sometimes replacing the bearing in the VAZ 2110 gearbox becomes urgent. We have to repair it because it gets damaged. In order for the replacement of the gearbox bearing on a VAZ 2110 to be successful, you need to gain access to it, you need to understand the structure of the gearbox, etc. To ensure its serviceability, you should carefully check the clutch release mechanism and gear shifting.

Examination

VAZ 2110 replacement of box bearings

A possible malfunction can be considered a low oil level. At such moments, not only do the bearings stop functioning correctly, but every part of the gearbox begins to adhere poorly. If you do not fill in the required amount of oil or transmission fluid in time, the parts will quickly wear out. The car is installed above the inspection hole. A thorough inspection is carried out at the time of checking for oil leaks.

Note. Oil may leak through crankcase joints, wheel drive seals or gear selector rods.

With the clutch depressed (see Repairing the VAZ 2110 clutch - we do it ourselves), you need to gradually shift all gears. Their accuracy of operation is checked at the time of switching on and off. If necessary, the gear shift mechanism is adjusted.

Replacing bearings in the box of a VAZ 2110 input shaft

When the transmission lever is in neutral, the engine must be started. When you press the clutch pedal, you must try to hear the operation of the gearbox bearings. The characteristic sound of a breakdown appears the moment the pedal is released. As soon as you press, the sound disappears again. If the sound is loud, the bearings should be replaced.
The operation of the gearbox is also checked while the vehicle is moving. It is necessary to accelerate the car, then slow braking. Gears shift up and then down. Here you should check the operation of the synchronizers and the clarity of the gear shift. There should be no extraneous sounds when the gearbox is operating. If the load increases, you must ensure that gears are not changed randomly.

Note: if there is a need to replace only one part of the mechanism, there is no need to completely disassemble the unit. It is enough to remove the part needed for replacement.

Notes, recommendations and repair tips

1. The average service life before product replacement is 800,000 off-on cycles. 2. Recommendations for extending the life of the release bearing: – Avoid holding the pedal for a long time; – It is advisable to release the pedal slowly and press quickly, without stopping between the extreme positions; – Prevent moisture and dirt from entering the transmission; – Carefully lubricate the part during the replacement process (see video below). 3. After replacement, when performing reassembly, treat the threads of bolt connections with graphite lubricant. 4. Purchase auto parts from previously proven retail outlets, check dealer documents and product quality certificates. 5. The video shows an example of performing repairs without an inspection hole, as well as without removing the gearbox.

How to change?

Some motorists immediately rush to a car service center. In turn, for service station technicians, replacing the VAZ 2114 input shaft bearing is not the most profitable job.

Therefore, car owners are often refused, citing workload. This is not surprising, because the work of replacing this element requires a careful approach, and the cost of services is quite low. Therefore, in order not to waste personal time, it is recommended to do all the work with your own hands. To do this, you need to follow the following instructions:

Some sources recommend completely disassembling the gearbox. In fact, you don’t have to do this, but the box will still need to be removed;
First you need to disconnect the battery;
you need to disconnect all the chips from the gearbox;
then the exhaust pipe (exhaust system pants) is removed;
dismantling the gearbox;
Next you need to remove the bell. This work is also optional, but the bell will interfere with the repair work;
The gearbox should be thoroughly cleaned of dirt;
Using a screwdriver, you need to remove the retaining rings. They are the ones that hold the bearing. First you need to pry the ring and then loosen it a little. To simplify the procedure, it is recommended to use tweezers;
To dismantle the bearing, you need to pry it off and also move the input shaft forward.

Gearbox assembly

Assembling a VAZ 2110 box

After replacing each bearing, the gearbox must be reassembled. In this case, the differential, input shaft and output shaft must be assembled in the opposite order to disassembly. Assembly must be carried out carefully to avoid any remaining parts. To complete the assembly process of the gearbox mechanism, you must:

The surfaces of the crankcases must be cleaned of sealant residues.
Each part is washed with diesel fuel or kerosene. After the washing process, it is necessary to wipe each part. After washing, lubricate each part with clean transmission oil.
A new gear selector rod seal is installed.
The gear selection mechanism rod and lever are installed.
For stable fixation, adhesive fixative is applied to the cleaned surface of the lever fastening screw.
The gear selection mechanism is installed.
New bearing and differential outer races must be installed in the crankcase. Before mounting the bearings, it is necessary to install the adjusting rings.
New drive seals are installed.
The input shaft, secondary shaft, and reverse gear are mounted.
A mandrel is installed to fix the gears.

Note: The subsequent assembly process is the opposite of the disassembly process. You should start from the last disassembly item and gradually move up the list. Before installing covers and crankcases, their surface must be degreased. Never install gaskets between the clutch housing and the gearbox. This setup can be quite frustrating when adjusting the bearings.

Detailed videos and photos on this topic can be viewed on the Internet. This must be done with full attention, since the work will be carried out with your own hands and mistakes cannot be avoided. But you shouldn’t despair, because the instructions give practical advice and recommendations. The price of bearings may vary depending on the place of sale. You should carefully select bearings, as there are many low-quality products and defective products on the market.
