B: INSPECTION
1. CLUTCH DISC
1) Facing wear
Measure the depth of rivet head from the surface of facing.
Replace if facings are worn locally or worn down to less
than the specified value.
Depth of rivet head:
Standard value
1.3—1.9 mm (0.051—0.075 in)
Limit of sinking
0.3 mm (0.012 in)
CAUTION:
Do not wash clutch disc with any cleaning fluid.
B2M0329A
2) Hardened facing
Correct by using emery paper or replace.
3) Oil soakage on facing
Replace clutch disc and inspect transmission front oil seal,
transmission case mating surface, engine rear oil seal and
other points for oil leakage.
B2M0330A
4) Deflection on facing
If deflection exceeds the specified value at the outer cir-
cumference of facing, repair or replace.
Limit for deflection:
1.0 mm (0.039 in) at R = 107 mm (4.21 in)
B2M0333A
5) Worn spline, loose rivets and torsion spring failure
Replace defective parts.

2. CLUTCH COVER
Visually check for the following items without
disassembling, and replace or repair if defective.
1) Loose thrust rivet.
2) Damaged or worn bearing contact area at center of
diaphragm spring.

3. FLYWHEEL
CAUTION:
Since this bearing is grease sealed and is of a nonlu-
brication type, do not wash with gasoline or any sol-
vent.
1) Damage of facing and ring gear
If defective, replace flywheel.
G2M0251
2) Smoothness of rotation
Rotate ball bearing applying pressure in thrust direction.
If noise or excessive play is noted, replace ball bearing as
follows:
(1) Drive out ball bearing from flywheel.
(2) Press bearing into flywheel until bearing end sur-
face is flush with clutch disc contact surface of flywheel.
Do not press inner race.

C: INSTALLATION
1) Install flywheel.
2) Install ST, and tighten the flywheel attaching bolts to the
specified torque.
ST 498497100 CRANKSHAFT STOPPER
Tightening torque:
72±3 N⋅m (7.3±0.3 kg-m, 52.8±2.2 ft-lb)
NOTE:
Tighten flywheel installing bolts gradually. Each bolt should
be tightened to the specified torque in a crisscross fashion.
G2M0253
3) Insert ST into the clutch disc and install them on the
flywheel by inserting the ST end into the pilot bearing.

G2M0254
4) Install clutch cover on flywheel and tighten bolts to the
specified torque.
NOTE:
When installing the clutch cover on the flywheel, position
the clutch cover so that there is a gap of 120°or more
between“0”marks on the flywheel and clutch cover. (“0”
marks indicate the directions of residual unbalance.)
Note the front and rear of the clutch disc when installing.
Tighten clutch cover installing bolts gradually. Each bolt
should be tightened to the specified torque in a crisscross
fashion.
Tightening torque:
15.7±1.5 N⋅m (1.6±0.15 kg-m, 11.6±1.1 ft-lb)
5) Remove ST.

3. Thermostat
A: REMOVAL AND INSTALLATION
1) Drain engine coolant.
Set container under the vehicle, and remove drain cock
from radiator.
2) Disconnect radiator outlet hose from thermostat cover.
3) Remove thermostat cover and gasket, and pull out the
thermostat.
G2M0227
4) Install the thermostat in the intake manifold, and install
the thermostat cover together with a gasket.
CAUTION:
When reinstalling the thermostat, use a new gasket.
The thermostat must be installed with the jiggle pin
upward.
In this time, set the jiggle pin of thermostat for front
side.
G2M0215
B: INSPECTION
Replace the thermostat if the valve does not close com-
pletely at an ambient temperature or if the following test
shows unsatisfactory results.
Immerse the thermostat and a thermometer in water. Raise
water temperature gradually, and measure the temperature
and valve lift when the valve begins to open and when the
valve is fully opened. During the test, agitate the water for
even temperature distribution. The measurement should
be to the specification.
Starts to open:
76.0—80.0°C (169—176°F)
Fully opens:
91°C (196°F)
