CLUTCH UNIT INSTALLATION
1. INSTALL CLUTCH DISC AND COVER ON FLY±WHEEL
(a) Insert SST in the clutch disc, and then set them and the cover
in position.
SST 09301±00110
(b) Align the matchmarks on the clutch cover and fly±wheel.
(c) Tighten the bolts evenly and gradually while pushing the SST.
Make several passes around the cover until it is snug.
(d) Torque the bolts on the clutch cover in the order shown.
Torque: 19 NVm (195 kgfVcm, 14 ftVlbf)
HINT: Temporarily tighten the No.1 and No.2 bolts.
2. CHECK DIAPHRAGM SPRING TIP ALIGNMENT
Using a dial indicator with roller instrument, check the dia-
phragm spring tip alignment.
Maximum non±alignment:
0.5 mm (0.020 in.)
If alignment is not as specified, use the SST to adjust the dia-
phragm spring tip alignment.
SST 09333±00013
3. REMOVE CLUTCH COVER AND CLUTCH DISC
4. INSTALL CLUTCH RELEASE FORK
(a) Install the wave washer and pin to release fork.
(b) Install a new E±ring.
5. APPLY MOLYBDENUM DISULPHIDE LITHIUM BASE
GREASE (NLGI NO.2)
(a) Apply release hub grease to these parts:
wRelease fork and hub contact point
wRelease fork and push rod contact point
wRelease fork pivot point

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.

PRECAUTION
wCare must be taken to replace parts properly because they could affect the
performance of the steering system and result in a driving hazard.
wThe steering wheel pad has an SRS (Supplemental Restraint System) airbag built in,
so take all due precautions when handling it. For more details, see the RS section.
