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 lowpres-
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.
3. CHECK DIRECT CLUTCH BUSHING
Using a dial indicator, measure the inside diameter of the
direct clutch bushing.
Maximum inside diameter:
47.07 mm (1.8531 in.)
If the inside diameter is greater than the maximum, re-
place the direct clutch.
DIRECT CLUTCH ASSEMBLY
1. INSTALL CLUTCH PISTON IN DIRECT CLUTCH DRUM
(a) Install new O±rings to the piston. Coat the O±rings with
AT F.
(b) Being careful not to damage the O±rings, press the piston
into the drum with the cup side up.
2. INSTALL PISTON RETURN SPRING
(a) Place the return spring and snap ring onto the piston.
(b) Place SST on the spring retainer, and compress the re-
turn spring with a shop press.
