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.

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.

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.

Clutch Set Force
1. Invert the pressure plate assembly.
2. Place a metal sheet “A” on the pressure plate.
3. Compress the pressure plate assembly until the distance
“B” becomes specified.

Diaphragm Spring Finger Height
1. Place a new driven plate or the appropriate spacer beneath
the pressure plate.
2. Fully compress the pressure plate and diaphragm spring.
There are two ways to do this.

Use a bench press to press down on the assembly from the
top.
 Tighten the fixing bolts.
NOTE: Preload on diaphragm spring finger must be 49 - 98 N
(11 - 22 lb) in direction of release, when clutch cover assembly
is bolted to the flywheel.

3. Measure the spring height from base to spring tip "H". If the
measured value exceeds the specified limit, the pressure
plate assembly must be replaced.
