The clutch consists of a basket (pressure plate assembly) and the driven disk. The basket is a steel casing in which a pressure disk is installed. From the casing side, the disk is pressed by a diaphragm-type pressure spring. The clutch basket is bolted to the flywheel. A driven disk is installed between the pressure plate and the flywheel.
Friction linings are riveted to both sides of the driven disk. To dampen torsional vibrations at the moment the clutch is engaged, a damper with cylindrical springs is built into the driven disk. The driven disk hub engages splined with the primary shaft of the gearbox.
The hydraulic clutch release drive consists of the master and slave clutch release cylinders, connected by a pipeline. Brake fluid is used as the working fluid in the clutch hydraulic drive. It enters the clutch master cylinder from the brake master cylinder reservoir. For this purpose, a branch pipe is made on the left side of the tank.
Note: The working fluid in the clutch release hydraulic system must be replaced regularly in accordance with the maintenance schedule.
The slave cylinder is installed in the clutch housing and, together with the release bearing, is assembled into a single, non-separable unit. The bleed nipple of the working cylinder is located outside the clutch housing...
...and closed with a rubber cap.
The following can be attributed to faults in the master and slave clutch cylinders:
- wear of clutch master cylinder seals;
- leakage of working fluid at the joints of tubes and fittings and from under the cuffs of the working cylinder.
Correct operation of the hydraulic clutch release drive is only possible if there is no air in the system, which could prevent the clutch from disengaging completely. As a result, gear shifting will be difficult or impossible. Air can enter the system when the fluid level in the master brake cylinder drops below the permissible limit, as a result of a breach in the tightness of the connections. The tightness must be restored by replacing damaged parts. To remove air, simply bleed the clutch release hydraulic drive.
