B: INSPECTION
1. RELEASE BEARING
CAUTION:
Since this bearing is grease sealed and is of a nonlu-
brication type, do not wash with gasoline or any sol-
vent when servicing the clutch.
1) Check the bearing for smooth movement by applying
force in the radial direction.
Radial direction stroke:
FWD; Approx.
1.0 mm (0.039 in)
AWD; Approx.
1.4 mm (0.055 in)
G2M0240
2) Check the bearing for smooth rotation by applying pres-
sure in the thrust direction.
3) Check wear and damage of bearing case surface con-
tacting with lever.
G2M0241
2. RELEASE LEVER
Check lever pivot portion and the point of contact with
release bearing case for wear.
C: INSTALLATION
CAUTION:
Before or during assembling, lubricate the following
points with a light coat of grease.
Inner groove of release bearing
Contact surface of lever and pivot
Contact surface of lever and bearing
Transmission main shaft spline (Use grease contain-
ing molybdenum disulphide.)

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.

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)
