15.1. A mechanical transmission

The transmission will transform a twisting moment transferred from the engine, on size and a direction. It is necessary for maintenance of optimum speed and passableness of the car, and also for the most economic work of the engine and for movement of the car by a backing. Besides, transmissions separates the engine and transmission during a stop and parking of the car and at its movement by inertia with working engine.
Transmission details are placed in картере which bolts fastens to a back part of the engine.
The twisting moment from the engine through coupling is transferred to a leading shaft of a transmission. A conducted shaft the transmission transfers a twisting moment through differential to drive shaft. Transfer inclusion is carried out by moving sliding муфты the synchronizer therefore the gear wheel rigidly incorporates to transmission shaft.
The transmission represents its very difficult unit it is recommended to repair in a specialised workshop, therefore in the present section removal and transmission installation are resulted only.
For transmission removal it is necessary to lift the car and to fix it in this position. Also use of a stationary jack is necessary.
