GENERAL DESCRIPTION
HYDRAULIC CONTROL TYPE
HEC Engine Series4J Engine Series
6VD1
The clutch assembly consists of the pressure plate, the clutch cover, the diaphragm spring pivot pin and the driven
plate assembly.
The clutch pedal is connected to the shift block through the clutch shaft and the shift fork.
The driven plate assembly is installed between the flywheel and the pressure plate.
Diaphragm spring pressure holds the driven plate against flywheel and the pressure plate to provide the friction
necessary to engage the clutch.
Depressing the clutch pedal moves the shift fork against the shift block.
The shift block forces the release bearing against the diaphragm to overcome the force of the diaphragm spring and
separate the driven plate from the flywheel and pressure plate to disengage the clutch.
Except 6VD1 (3.2L) engine model, the conventional push-type clutch is used.
For 6VD1 (3.2L) engine model, the pull-type clutch is employed. The pull-type clutch is disengaged by pulling the
release lever (release bearing) to disengage the pressure plate.

SLAVE CYLINDER
MUA Series
MSG Series
4J Engine Series
6VD1 Engine Series
The slave cylinder converts hydraulic energy into mechanical energy.
Hydraulic fluid supplied by the master cylinder moves the slave cylinder piston to actuate the shift fork.
The mechanical energy produced by the slave cylinder is directly proportional to the diameters of the master
cylinder and the slave cylinder.
A bleeder screw is provided to bleed the slave cylinder.

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.
