1. INSPECT DISC, PLATE AND FLANGE
Check to see if the sliding surface of the disc, plate and
flange are worn or burnt. If necessary, replace them.
HINT:
★ If the lining of the disc is peeling off or discolored, or
   even if a part of the printed numbers are defaced, re-
   place all discs.
★ Before assembling new discs, soak them in ATF for
   at least 15 minutes.

2. CHECK FORWARD CLUTCH PISTON
(a) Check that the check ball is free by shaking the piston.
(b) Check that the valve does not leak by applying low-pres-
    sure compressed air.

3. CHECK FORWARD CLUTCH DRUM BUSHING
Using a dial indicator, measure the inside diameter of the
forward clutch drum bushing.
Maximum inside diameter:
    24.08 mm (0.9480 in.)
If the inside diameter is greater than the maximum, re-
place the forward clutch drum.
