INSTALLATION
1. INSTALL CLUTCH DISC AND COVER ON FLYWHEEL
(a) Insert SST in the clutch disc, then set them and the cover
in position.
SST 09301-001 10
(b) Align the matchmarks on the clutch cover and flywheel.
(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 N´m (195 kgf´cm, 14 ft´lbf)
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 the alignment is not as specified, use 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:

Release fork and hub contact point

Release fork and push rod contact point

Release fork pivot point

3. DRIVE TRAIN AND CHASSIS2. BRAKE SYSTEM
The brake system is one of the most important safety components. Always follow the directions and
notes given in section BR of the repair manual for the relevant model year when handling brake
system parts.
NOTICE: When repairing the brake master cylinder or TRAC system, bleed the air out of the TRAC
system.
The drive train and chassis are components-that can have great effects on the running performance
and vibration resistance of the vehicle. After installing components in the sections listed in the table
below, perform alignments to ensure correct mounting angles and dimensions. Particularly accurate
repair of the body must also be done to ensure correct alignment.
HINT: Correct procedures and special tools are required for alignment. Always follow the directions
given in the repair manual for the relevant model year during alignment and section DI of this manual.

3. Temporarily install the front fender and hood,
and check the fit. 1. When temporarily installing the new parts,
determine the installation position by the
assembly mark.
2. Measurements must be accurate with the
body dimension diagram, as this affects the
front wheel alignment.
