In the on state, the pressure plate presses the driven disc under the influence of the diaphragm spring against the flywheel and closes the kinematic circuit between the engine and gearbox.
The clutch release fork is located in the gearbox housing. A maintenance-free release bearing is attached to it, which, when the clutch is disengaged, is pressed against the pressure plate.
Clutch drive on all front wheel drive petrol models up to 9/89 MY. and all station wagon models are carried out through a cable. All-wheel drive and diesel options, as well as all vehicles from 10/89 MY. (except station wagon) have a hydraulic clutch. 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 in the master cylinder through the piston rod, which is transferred through the hydraulic pipeline to the working cylinder. The piston of the working cylinder presses the release bearing against the spring of the pressure plate through the fork and slightly retracts it. 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 filled through a common expansion tank (Depending on the model, a separate tank can also be installed).
