1. MECHANICAL APPLICATION TYPE
1) While pushing release lever

3to pivot and twisting it to
both sides, fit retainer spring

5onto the constricted portion
of pivot.
NOTE:
Confirm that retainer spring is securely fitted by observing
it through the main case hole.
2) Install release bearing

6and fasten it with two clips

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.
