DISASSEMBLY OF FORWARD CLUTCH
1. CHECK PISTON STROKE OF FORWARD CLUTCH
Using a dial indicator (long type pick or SST), measure the for-
ward clutch piston stroke applying and releasing the
compressed air (4 ± 8 kg/cm2, 57 ± 114 psi, 392 ± 785
kPa) as shown.
SST 09350±32014 (09351±32190)
Piston stroke: 1.41 ± 1.82 mm (0.0555 ± 0.0717 in.)
If the piston stroke is greater than the maximum
inspect the each component.

4. REMOVE RETURN SPRINGS
(a) Place SST on the spring retainer and compress the
springs with a shop press.
SST 09350±32014 (09351±32070)
(b) Remove the snap ring with the snap ring pliers.
5. REMOVE CLUTCH PISTON
(a) Apply compressed air into the oil passage to re-
move the piston.
if the piston does not come out, use needle±nose pliers
to remove it.(c) Remove the spring retainer and eighteen return
springs. 3. REMOVE FLANGE, DISCS AND PLATES2. REMOVE SNAP RING FROM CLUTCH DRUM

2. INSPECT DISCS, PLATES AND FLANGE
Check if the sliding surfaces of the discs, plates are
flange are worn or burnt. If necessary, replace them.
HINT:
wIf the lining of the disc is exfoliated or discolored, o
even a part of the printed numbers are defaced, re-
place all discs.
wBefore assembling new discs, soak them in ATF for
at least two hours.
INSPECTION OF FORWARD CLUTCH
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 pressure
compressed air. 6. IF NECESSARY, REMOVE OIL SEAL RINGS
Remove the two oil seal rings from the shaft.(b) Remove the two O±rings from the piston.

3. INSTALL PISTON RETURN SPRINGS
(a) Place the eighteen springs, spring retainer and snap
ring onto the piston.
(b) Place SST on the spring retainer, and compress the
springs with a shop press.
SST 09350±32014 (09351±32070)
(c) Install the snap ring with snap ring pliers.
Be sure the end gap of the snap ring is not aligned
with the spring retainer claw.
ASSEMBLY OF FORWARD CLUTCH
1. INSTALL OIL SEAL RINGS
Instal! the two oil seal rings to the shaft.
NOTICE: Do not spread the ring ends more than neces-
sary.
HINT: After installing the oil seal rings, check that they
move smoothly.
4. INSTALL PLATES, DISCS AND FLANGE
(a) Install the plates and discs.
Install in order: P=Plate D= Disc
P±D±P±D±P±D±P±D
(b) Install the flange with the flat end facing downward.(b) Coat the O±rings with ATF.
(c) Press the piston into the drum with the cup side up, be-
ing careful not to damage the O±rings. 2. INSTALL CLUTCH PISTON TO CLUTCH DRUM
(a) Install the two new O±rings to the piston.

6. RECHECK PISTON STROKE OF FORWARD CLUTCH
Using a dial indicator (long type pick or SST), measure
the forward clutch piston stroke applying and releasing
the compressed air (4 ± 8 kg/cm2, 57 ± 114 psi, 392 ±
785 kPa) as shown.
SST 09350±32014 (09351±32190)
Piston stroke: 1.41 ± 1.82 mm (0.0555 ± 0.0717 in.)
If the piston stroke is less than the limit, parts may be
misassembled and reinstall them.
If the piston stroke nonstandard, select another flange.
HINT: There are two different flange thickness.
Flange thickness: 3.00 mm (0.1181 in.)
3.37 mm 10.1327 in.) 5. INSTALL SNAP RING
Check that the end gap of snap ring is not aligned with
one of the cutouts.

DISASSEMBLY OF ONE±WAY CLUTCH AND
SUN GEAR
7. CHECK OPERATION OF ONE±WAY CLUTCH
Hold the sun gear and turn the hub. The hub should turn
freely clockwise and should lock counterclockwise.
2. REMOVE SECOND BRAKE HUB AND ONE±WAY
CLUTCH FRONT SUN GEAR .
While turning the hub clockwise, remove the one±way
clutch from the sun gear.
