CLUTCH 7C-7
PRESSURE PLATE ASSEMBLY
HEC Engine Series4J Engine Series
6VD1 Engine Series
The pressure plate assembly consists of the clutch cover, the pressure plate with diaphragm spring.
Operating the clutch pedal causes the pressure plate to move in an axial direction to engage and disengage the
clutch.
DRIVEN PLATE ASSEMBLY
The driven plate assembly consists of the plate and the facing.
The plate consists of the clutch center, the cushioning plate and the torsion springs.
The facing is riveted to both sides of the cushioning plate.
The cushioning plate provides a longer service life by minimizing wear and vibration at the clutch contact surfaces.
