When engaged, the pressure plate presses the driven disk under the action of the diaphragm spring to the flywheel and closes the kinematic chain between the engine and the gearbox.
The gearbox housing contains a clutch release fork. It is fitted with a maintenance-free release bearing, which is pressed against the pressure plate when the clutch is released.
The clutch on all petrol models with front-wheel drive up to 9/89 and all station wagon models is operated via a cable. All-wheel drive and diesel variants, as well as all vehicles since 10/89, are operated via a cable. (except station wagon) have a hydraulic clutch drive. The piston of the working cylinder of the hydraulic system is adjacent to the clutch release fork. When the clutch pedal is depressed, pressure is created through the piston rod in the master cylinder, which is transferred through the hydraulic pipeline to the working cylinder. The piston of the working cylinder presses the release bearing through the fork against the spring of the pressure plate and slightly moves it away. Due to this, the driven disk between the flywheel and the pressure plate is released, and the kinematic chain between the engine and the gearbox is opened. The hydraulic system is filled with brake fluid, which is poured through a common compensation tank (depending on the model, a separate tank may also be installed).
Clutch from 10/89.
