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.

Driven Plate Splined Hub Spline Wear
1. Clean the driven plate splined hub.
2. Install the driven plate to the transmission top gear shaf
t
spline.
3. Set a surface gauge to the driven plate outside
circumference.
4. Slowly turn the driven plate counterclockwise.
Measure the spline rotation play as you turn the driven
plate.
If the measured value exceeds the specified limit, the driven
plate assembly must be replaced.

Rivet Head Depression
Use a depth gauge or a straight edge with steel rule to
measure the rivet head depression

1 from the facing surface

2.
Be sure to measure the rivet head depression on both sides of
the driven plate.
If the measured value is less than the specified limit, the facing
must be replaced.
