Clutch Disc and Cover

CLUTCH SYSTEM

2) Install the clutch cover to the flywheel and tight-
en the bolts to the specified torque.

NOTE:
• When installing the clutch cover to the flywheel,
position the clutch cover so that the distance be-
tween unbalance marks (

 paint marks) is at least

120°. (The unbalance mark 

 indicates the direc-

tion of residual unbalance.)
• Note the front and rear of the clutch disc when in-
stalling.
• Temporarily tighten the bolts by hand. Each bolt
should be tightened to the specified torque in a
crisscross order.

Tightening torque:

16 N·m (1.6 kgf-m, 11.8 ft-lb)

3) Remove the ST.

NOTE:
The illustration below is for a Non-turbo model.
However, perform the same procedures for the
Turbo model.

1. CLUTCH DISC

1) Facing wear:
Measure the depth from the facing surface to the
rivet head. Replace if the face is worn locally or
worn down to less than the specified value.

Depth to rivet head:

Limit of sinking

0.3 mm (0.012 in)

NOTE:
Do not wash the clutch disc with any type of clean-
ing fluid.

2) Hardened facing
Replace the clutch disc.
3) Oil soakage on facing
Replace the clutch disc and inspect the transmis-
sion front oil seal, transmission case mating sur-
face, engine rear oil seal and other locations for oil
leakage.

Limit for deflection:

0.7 mm (0.028 in) at R = 110 mm (4.33 in)

5) If there is spline wear, loose rivets, failed damper
springs, etc., replace the clutch disc.

2. CLUTCH COVER

NOTE:
Visually check the following items without disas-
sembling, and replace or repair if defective.
1) Loose thrust rivet
2) Damaged or worn bearing contact area at the
center of diaphragm spring

3) Damaged or worn disc contact surface of the
pressure plate
4) Loose strap plate installation area
5) Worn diaphragm sliding area

2) Tighten the flywheel mounting bolts to the spec-
ified torque.

NOTE:
Tighten the flywheel attachment bolts gradually.
Each bolt should be tightened to the specified
torque in crisscross order.

Tightening torque:

72 N·m (7.3 kgf-m, 53.1 ft-lb)

C: INSPECTION

NOTE:
The illustration below is for a Turbo model. Howev-
er, perform the same procedures for the Non-turbo
model.

CAUTION:
Since this bearing is grease-sealed and is a
non-lubrication type, do not wash with gasoline
or any solvents.
1) If there is damage or defectiveness in the facing
sliding surface or ring gear, replace the flywheel.

2) Smoothness of rotation
Rotate the ball bearing while applying pressure in
the thrust direction.
3) If noise or excessive play is noted, replace the
flywheel.
