CLUTCH: CLUTCH UNIT: INSPECTION

INSPECTION

1. INSPECT CLUTCH DISC ASSEMBLY





(a) Using a vernier caliper, measure the rivet head depth.
Minimum rivet depth:
0.3 mm (0.012 in.)
If the depth is less than the minimum, replace the clutch disc assembly.
(b) Install the disc on the transaxle.
NOTE: Take care not to insert the clutch disc in the wrong direction.





(c) Using a dial gauge, measure the disc runout.
Maximum runout:
0.8 mm (0.031 in.)
If the runout is greater than the maximum, replace the clutch disc assembly.






2. INSPECT CLUTCH COVER ASSEMBLY
(a) Using a vernier caliper, measure the depth and width of the worn areas of the diaphragm spring.
Maximum wear:





If the wear is greater than the maximum, replace the clutch cover assembly.






3. INSPECT FLYWHEEL SUB-ASSEMBLY
(a) Using a dial gauge, measure the flywheel runout.
Maximum runout:
0.1 mm (0.004 in.)
If the runout is greater than the maximum, replace the flywheel sub-assembly.






4. INSPECT CLUTCH RELEASE BEARING ASSEMBLY
(a) Check that the bearing moves smoothly without abnormal resistance by turning the sliding parts of the bearing (contact surfaces with the clutch cover) while applying force in the axial direction.
(b) Inspect the bearing for damage or wear.
If necessary, replace the release bearing assembly.
