REMOVAL
AND
REFITTING
OF
CLUTCH WITH DEVICE RECOVERY
COMBINED
Removal
The operation consists of:
- removal-refitting of transmission shafts (see section
505620)
- removal-refitting of gear box (see section 530210).
Insert clutch centring pin 99370205 (1) in the shaft support
bearing.
Locate the position of retainer (2): it is positioned between the
engine flywheel plug for clutch assembly centering and a hole
for the screw used to fasten the same. It sticks out the clutch
assembly by approximately 3 mm.
Remove the clutch disk (3) by extracting the centring pin
99370205 (2).
CHECKS
The checks to be made are as follows:
- the faying surface, on the engine flywheel, of the driven
disk must not be excessively worn or scored.
- the teeth of the toothed crown must not be worn or
broken.
If this is not the case, disassemble the engine flywheel
(operation 540850) as described in the relevant paragraph at
section 2.
Proceed on the engine flywheel as described in relevant
paragraph (operation 540853) at section 2.
Check that there are no oil leaks, even of a slight entity, from
the seal of the rear drive shaft; otherwise remove the flywheel
as described in the relevant paragraph.
Replace the seal ring as described in section 2.
Check that the support bearing or bushing of the take up shaft
on the gears fitted to the drive shaft are not worn or broken
and, if necessary, replace them as described in the relevant
paragraph (540852).
Check the condition of the thrust pad; the driven disk support
surface must not be scored or excessively worn or should
there be signs of overheating; the diaphragm spring must be
in perfect condition.
Check the condition of the driven disk:
- the friction seals must not be excessively worn or present
signs of overheating, or traces of oil or grease;
- there should be very little backlash between the hub and
gear take up shaft;
- the hub rings must not be loose or broken.
Should any anomaly be found, the full clutch shall be replaced.
Inspect the conditions of the clutch-release bearing and the
release lever, should any anomaly be found, the concerned
part shall be replaced.
In the event that the clutch release lever is replaced,
calibration shall be carried out after re-attaching the
gearbox, as described in the relevant charter of the
“Gearbox” section.
