DIRECT CLUTCH INSPECTION
1. INSPECT 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.
2. INSPECT DISCS, PLATES AND FLANGE
Check if the sliding surfaces of the discs, plates 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.
