diaphragm spring pressure is
the three clutch pressure plate retracting springs, then remove the pressure
plate from the clutch cover assembly, Fig. 112. Note the position of the "O" marks on the
pressure plate and cover.
These must be matched when reassembling in order to maintain proper
NOTE—For ease of servicing,
the clutch cover, diaphragm spring and two pivot rings are built up as an
assembly. If inspection shows that there is a defect in any of these parts
it will be necessary to replace the complete cover
step in connection with inspection of the clutch is to wash all parts
(except the throwout bearing and
disc) in clean gasoline or cleaning solvent.
CAUTION—The clutch throwout
bearing is permanently packed with lubricant and should not be soaked

1. Inspect the pressure plate and flywheel for
any indication of scores on the
contact surface. Then check
the three pressure plate drive lugs for burrs. Make sure that these lugs move
freely in the three slots in
the cover. Check the clearance between the lugs and the cover; this
clearance should be from .002"
2. Check the throwout bearing for roughness
and free fit on the sleeve of
the transmission clutch gear bearing retainer.
3. Check the run-out of the transmission pilot
hole in the clutch housing. Fig. 113. This should be within .008" indicator
