INSPECTION OF CLUTCH PARTS
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 is excessive, replace the flywheel.
4. INSPECT DIAPHRAGM SPRING FOR WEAR
Using calipers, measure the diaphragm spring for depth and width of wear. Maximum: Depth 0.6 mm (0.024 in.) Width 5.0 mm (0.197 in.) If necessary, replace the clutch cover.
5. 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.
INSTALLATION OF CLUTCH UNIT (MAIN POINT OF INSTALLATION)
1. INSTALL CLUTCH DISC AND COVER ON FLYWHEEL
Insert the SST in the clutch disc, and then set them and the cover in position.
2WD SST 09301-32010
4WD SST 09301-17010
2. INSTALL CLUTCH COVER
(a) Align the matchmarks on the clutch cover and flywheel.
(b) Torque the bolts on the clutch cover in the order shown.
Torque: 195 kg-cm (14 ft-lb, 19 N-m)
HINT: Temporarily tighten the No.1 and No.2 bolts.
3. CHECK DIAPHRAGM SPRING TIP ALIGNMENT
Using a dial indicator with roller instrument, check the diaphragm spring tip alignment. Maximum non-alignment: 0.5 mm (0.020 in.)
If alignment is not as specified, using SST, adjust the diaphragm spring tip alignment. SST 09333-00013
4. APPLY MOLYBDENUM DISULPHIDE LITHIUM BASE GREASE (NLGI NO.2) AS SHOWN
