Diabram of the Clutch
The clutch control fork, mounted in the transmission housing, carries the throwout bearing. The throwout bearing is permanently lubricated and requires no maintenance.
Clutch actuation at disengagement is by way of the clutch pedal, clutch cable, control fork, and throwout bearing. The throwout bearing exerts pressure upon the segments of the diaphragm spring, displacing it axially. The resulting deflection of the diaphragm spring relieves pressure from the pressure plate and, thus, from the clutch disc, resulting in disengagement of engine from the transmission.
Clutch maintenance is limited to adjustment of the clutch pedal clearance of 20-25 mm (3/4 to 1 in.) in the course of normal clutch lining wear, and also to the adjustment of the clutch pedal travel limiter.
