REMOVAL AND REPAIR

Almost any DIY repair of a VAZ 2114 gearbox - installing new bearings, clutch or gears - involves removing it. To do this, you will need screwdrivers, a set of wrenches, WD-40 and hanging equipment to lift the unit.

When is it necessary to replace the input shaft?

Certain signs of malfunction indicate that it is time to replace the secondary shaft bearing :

Extraneous noise or whistling when the engine is running in neutral gear, which changes with increasing speed.
The knock of the gearbox while the car is moving, and this knock is heard in any gear.
Transmissions may turn on or off spontaneously.
If the bearing is jammed, the clutch will not engage or disengage.

Bearing wear can be influenced by various factors:

Poor initial bearing quality. When purchasing it, you should be picky in order to provide your car with a normal part.
Driving style. When you drive too aggressively and tear the lever, the bearing will definitely not last long.
Vehicle operating conditions. Garage storage and the absence of continuous overloads of the car can prolong the normal operation of all its components.
Ignoring regular maintenance.

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).

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.
