Leading parts
The leading elements of the design are two flat surfaces, machined and ground. One of them is the rear surface of the engine flywheel, and the second is the surface of the pressure plate. The pressure plate is enclosed in a clutch housing, which is attached to the flywheel with bolts.
Driven parts
The driven element of the design is the driven clutch disc with a splined sleeve. The sleeve moves freely on the splines of the primary shaft of the gearbox, transmitting torque to it.
Contact between the leading and driven elements of the clutch is ensured by spring force. The source of this force is a diaphragm-type pressure spring installed between the pressure plate and the clutch housing.
Working elements
The clutch drive system consists of a clutch pedal, a master cylinder and a concentric release cylinder.
Unlike earlier designs that used a release fork and fork lever to disengage the clutch, this system uses a concentric cylinder that directly disengages the clutch using force transmitted through the hydraulic drive system from the clutch pedal.
