CLUTCH PARTS INSPECTION AND
REPAIR
1. INSPECT CLUTCH DISC FOR WEAR OR DAMAGE
Using calipers, measure the rivet head depth.
Minimum rivet depth:
0.3 mm (0.012 in.)
If a problem is found, replace the clutch disc.
2. INSPECT CLUTCH DISC RUNOUT
Using a dial indicator, check the disc runout.
Maximum runout:
0.8 mm (0.031 in.)
If runout is excessive, replace the clutch disc.
3. INSPECT FLYWHEEL RUNOUT
Using a dial indicator, check the flywheel runout.
Maximum runout:
0.1 mm (0.004 in.)
If runout excessive, replace the flywheel. CL±12

4. INSPECT PILOT BEARING
Turn the bearing by hand while applying force in the axial
direction.
If the bearing sticks or has much resistance, replace the pilot
bearing.
5. IF NECESSARY, REPLACE PILOT BEARING
(a) Remove the 2 bolts at diametrically opposite points.
(b) Using SST, remove the pilot bearing.
SST 09303±35011
(c) Using SST and a hammer, drive in a new pilot bearing.
SST 09301±00110
(d) Install 2 new bolts.
(e) First, torque the 2 bolts uniformly a little at a time.
Torque: 49 NVm (500 kgfVcm, 36 ftVlbf)
(f) Then tighten the 2 bolts an additional 80±100°.

6. INSPECT DIAPHRAGM SPRING FOR WEAR
Using calipers, measure the diaphragm spring for depth and
width of wear.
Maximum:
A: Depth 0.6 mm (0.024 in.)
B: Width 5.0 mm (0.197 in.)
If necessary, replace the clutch cover.
7. INSPECT RELEASE BEARING
Turn the bearing by hand while applying force in the axial
direction.
HINT: The bearing is permanently lubricated and requires no
cleaning or lubrication.
If a problem is found, replace the bearing together with the
hub.
8. INSPECT FLYWHEEL DAMPER FOR GREASE LEAKAGE
If grease has sprayed onto the clutch housing, replace the fly-
wheel assembly.
9. INSPECT FLYWHEEL DAMPER ROTATIONAL
FREEPLAY
(a) Install the 2 bolts to the secondary flywheel at diametrically
opposite positions.
(b) Holding both the bolts, turn the secondary flywheel clockwise
until it stops.
(c) Put matchmarks on the primary and secondary fly±wheels at
this position.
(d) Then rotate the primary flywheel counterclockwise by hand
until it stops.
(e) Put matchmarks on the primary flywheel at this position.
(f) M e a s u r e t h e c i r c u m f e r e n t i a l length between the 2
matchmarks on the secondary flywheel.
Standard:
105 mm (4.134 in.)
(g) Repeat the preceding steps (d) to (f) 4 times and if the
measurement is greater than the maximum length replace
the flywheel assembly.
