Single-plate dry clutch with diaphragm spring, extended, mounted on engine hydraulic operation * The clutch play cannot be checked at the clutch pedal because of the automatic hydraulic adjustment. On the other hand perfect function of the clutch must be guaranteed by having a play of 0.5 mm between the push rod and master cylinder piston. This play cannot be measured it must be determined on the clutch pedal by sense of feeling. On the pedal tread plate it will be about 3 mm.
