FORWARD 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.
FORWARD CLUTCH ASSEMBLY
1. INSTALL OIL SEAL RINGS
Install the 3 oil seal rings to the shaft.
NOTICE: Do not spread the ring ends more than necessary.
HINT: After installing the oil seal rings, check that they
move smoothly.

OVERDRIVE DIRECT CLUTCH
DISASSEMBLY
1. CHECK PISTON STROKE OF DIRECT CLUTCH
Install a dial indicator and measuring terminal (SST) to-
gether, measure the piston stroke while applying and re-
leasing compressed air (392±785 kPa, 5±8 kgf/cm
2,
57±114 psi).
Piston stroke:
1.75±2.49 mm (0.0689±0.0980 in.)
