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.

(a) Install the plates and discs.
Install in order:
P=Plate D=Disc
P±D±P±D±P±D±P±D±P±D
(b) Install the flange with the flat end facing downward.
5. INSTALL SNAP RING
Check that the end gap of snap ring is not aligned with one
of the cutouts.

6. RECHECK PISTON STROKE OF FORWARD CLUTCH
Install a dial indicator and measuring terminal (SST) to-
gether, measure the forward clutch piston stroke while ap-
plying and releasing compressed air (392±785 kPa, 4±8
kgf/cm
2, 57±114 psi).
SST 09350±32014 (09351±32190)
Piston stroke:
1.79±2.21 mm (0.0704±0.0870 in.)
If the piston stroke is non±standard, select another
flange.
HINT: There are 2 different thicknesses for the flange.
Flange thickness:
2.30 mm (0.0906 in.)
2.70 mm (1.0630 in.)
