COMPONENTS
FIRST AND REVERSE BRAKE INSPECTION
INSPECT DISCS, PLATES AND FLANGES
Check if the sliding surfaces of the discs, plates and
flanges 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 assembly new discs, soak them in ATF for at
least 15 minutes.

OVERDRIVE DIRECT CLUTCH
DISASSEMBLY
1. CHECK PISTON STROKE OF DIRECT CLUTCH
Using a dial indicator, measure the piston stroke while ap-
plying and releasing compressed air (392 ± 785 kPa, 4 ±
8 kgf/cm
2, 57± 114 psi).
Piston stroke:
1.21 ± 1.91 mm (0.0476 ± 0.0752 in.)
If the piston stroke is greater than the maximum, inspect
the each component.

7. REMOVE PISTON FROM CLUTCH DRUM
(a) Install the clutch drum of the case.
(b) Apply compressed air to the pressure apply hole of the
case.
(c) Remove the piston from the clutch drum.
If the piston does not come out completely, use needle±
nose pliers to remove it.
(d) Remove the clutch drum from the case.
8. REMOVE O±RINGS

OVERDRIVE DIRECT CLUTCH INSPECTION
1. INSPECT OVERDRIVE DIRECT CLUTCH
(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 FLANGES
Check that the sliding surfaces of discs, plates and
flanges 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
two direct clutch bushings.
Maximum inside diameter:
22.09 mm (0.8697 in.)
