Fig. 111—Disengaged Position of Diaphragm Spring
causes the rim of the spring and
the pressure plate to move back away from the clutch disc,
disengaging the clutch. When the clutch pedal is released and the
throwout bearing no longer contacts the fingers, the "spring" in this
material causes the fingers to pivot about the rear pivot ring and the rim
to bear against the pressure plate.
A rattling noise in the clutch
assembly at idling speed with the clutch released may be caused by
insufficient tension on the pressure plate retracting springs. This noise
can be easily remedied by replacing the retracting springs as
1. Remove the clutch housing
2. Hand-crank the engine until one retracting
spring attaching bolt is at the
bottom. Remove the bolt and
retracting spring and install a new spring.
3. Replace the other retracting springs in the
same manner as described
Should the above not correct the
rattle, the clearance between the drive lugs on the pressure plate and the
slots in the clutch cover should be checked. If this clearance exceeds
.010", the pressure plate and/or cover assembly should be
replaced, to obtain proper clearance.
