Diaphragm Spring Finger Height
(Except 6VD1)
1. Place the appropriate spacer beneath the pressure plate.
Refer to the table below.
Spacer Thickness mm(in)
HEC, 4JG2T 8.0 (0.315)
4JA1, 4JB1T 7.8 (0.307)
2. Fully compress the pressure plate and the diaphragm
spring.
There are two ways to do this.
1) Use a bench press to press down the assembly from the
top.
2) Tighten the fixing bolts.
3. Measure the spring finger height

A from the base to the
spring tip.

6VD1Diaphragm Spring Finger Height (6VD1)
1. Place a new driven plate or a 8.0 mm (0.315 in) spacer
beneath the pressure plate.
2. Fully compress the pressure plate and diaphragm spring.
There are two ways to do this.
1) Use a bench press to press down on the assembly from
the top.
2) Tighten the fixing bolts.
NOTE: (6VD1)
Pre-load on diaphragm spring finger must be 49 - 98N (5.0
- 10.0 kg / 11 - 22 lb) in direction of release, when clutch
