(c) Using a screwdriver, install the snap ring. Be sure the end
gap of the snap ring is not aligned with the cutout portion
of the direct clutch drum.
4. CHECK PISTON STROKE OF DIRECT CLUTCH
(a) Place the direct clutch assembly onto the O/D support as-
sembly.
(b) Using SST and a dial indicator, measure the direct clutch
pack clearance while applying and releasing compressed
air (186-206 kPa, 1.9-2.1 kgf/cm
2, 27-30 psi).
SST 09350-30020 (09350-06120)
Pack clearance:
0.50 - 0.80 mm (0.0197 - 0.0315 in.)
If the pack clearance is less than the limit, parts may have
been assembled incorrectly, so check and reassemble
again.
If the pack clearance is non-standard, select another
flange.
HINT: There are 9 different flange thicknesses.

from touching the work stand, and place the O/D support
on them.
(b) Place the forward clutch onto the O/D support.
2. CHECK FORWARD CLUTCH PACK CLEARANCE
Using SST and a dial indicator, measure forward clutch
pack clearance while applying and releasing compressed
air (186-206 kPa, 1.9-21. kgf/cm
2, 27-30 psi).
SST 09350-30020 (09350-06120)
Pack clearance:
0.70-1.00 mm (0.0276-0.0394 in.)
If the values are non-standard, inspect the discs.

7. REMOVE 3 OIL SEAL RINGS FROM FORWARD
CLUTCH
FORWARD CLUTCH INSPECTION
1. INSPECT DISC, PLATE AND FLANGE
Check to see if the sliding surface of the disc, plate 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.
2. CHECK FORWARD 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.
3. CHECK FORWARD CLUTCH DRUM BUSHING
Using a dial indicator, measure the inside diameter of the
forward clutch drum bushing.
Maximum inside diameter:
24.08 mm (0.9480 in.)
If the inside diameter is greater than the maximum, re-
place the forward clutch drum.

FORWARD CLUTCH ASSEMBLY
1. INSTALL OIL SEAL RINGS
(a) Coat the 3 oil seal rings with ATF.
(b) Install the 3 oil seal rings to the forward clutch drum
groove, then snug them down by squeezing their ends to-
gether.
NOTICE: Do not spread the ring ends more than necessary.
HINT: After installing the oil seal rings, check that they ro-
tate smoothly.
2. INSTALL FORWARD CLUTCH PISTON
(a) Coat 2 new O-rings with AFT and install them on the for-
ward clutch piston.
(b) Being careful not to damage the O-rings, press the clutch
piston into the forward clutch drum with both hands.
3. INSTALL PISTON RETURN SPRING
(a) Install the piston return spring.
(b) Place SST on the spring retainer, and compress the re-
turn spring with a shop press.
SST 09350-30020 (09350-07040)
(c) Using SST, install the snap ring. Be sure the end gap of
the snap ring is not aligned with the spring retainer claw.
