Clutch Assembly (08.01)
Description
The clutch assembly is a balanced unit consisting of a flywheel, clutch friction plates and clutch cover.
The clutch is a twin plate, diaphragm spring type assembly. A concentric clutch slave cylinder is mounted around the first motion shaft in the torque tube bell housing.
The clutch master cylinder is mounted on the engine bulkhead and is operated directly by the clutch pedal.
A hydraulic connection from the master cylinder feeds pressurised fluid to the slave cylinder. The slave cylinder has an extension tube and bleed nipple extending from the left side of the bell housing for bleeding the system after any major work.
