18. INSPECT PACK CLEARANCE OF REVERSE CLUTCH
(a) Install the intermediate shaft on the transaxle rear cover.
(b) Using a dial indicator, measure the direct clutch pack
clearance while applying and releasing compressed air
(392 kPa, 4.0 kgf/cm
2, 57 psi).
Pack clearance:0.60−0.82 mm (0.02362−0.03228 in.)
If the pack clearance is less than the minimum, parts may have
been assembled incorrectly, so check and reassemble again.
If the stroke is not within standard, select another flange.

1. INSPECT PACK CLEARANCE OF FORWARD CLUTCH
(a) Install the forward clutch on the oil pump.
NOTICE:
Be careful not to damage the oil seal ring of oil pump.
(b) Using a dial indicator, measure the forward clutch pack
clearance while applying and releasing compressed air
(392 kPa, 4.0 kgf/cm
2, 57 psi).
Pack clearance:1.00−1.25 mm (0.0394−0.4921in.)
If the clearance is not within standard, inspect the discs, plates
and flange.
HINT:
As the opening is large, cover it with a shop rug to prevent the
compressed air from being released.
2. REMOVE FORWARD MULTIPLE DISC CLUTCH
CLUTCH DISC
(a) Using a screwdriver, remove the snap ring.
(b) Remove the flange, 5 discs and 5 plates from the input
shaft assy.

3. INSPECT FORWARD MULTIPLE DISC CLUTCH
CLUTCH DISC
(a) Check to see if the sliding surface of the disc, plate and
flange are worn or burnt.
If necessary, replace them.
HINT:
SIf the lining of the disc comes off or discolors, or even if
replace all discs.
SBefore assembling new discs, soak them in ATF for at
least 15 minutes.
4. REMOVE FORWARD CLUTCH RETURN SPRING
SUB−ASSY
(a) Place SST on the spring retainer and compress the return
spring with a press.
SST 09387−00020
(b) Using a snap ring expander, remove the snap ring.
NOTICE:
SStop the press when the spring sheet is lowered1−
2 mm (0.039−0.078 in.) from the snap ring groove,
preventing the spring sheet from deforming.
SDo not expand the snap ring excessively.
(c) Remove the clutch balancer from the input shaft.
(d) Remove the forward clutch return spring from the input
shaft.

5. INSPECT FORWARD CLUTCH RETURN SPRING
SUB−ASSY
(a) Using vernier calipers, measure the free length of the
spring together with the spring seat.
Standard free length: 26.74 mm (1.0528 in.)
6. REMOVE FORWARD CLUTCH PISTON SUB−ASSY
(a) Place the forward clutch drum onto the oil pump.
(b) Holding the forward clutch piston by hand, apply com-
pressed air (392 kPa, 4.0 kgf/cm
2, 57 psi) to the oil pump
to remove the forward clutch piston.
HINT:
When the piston cannot be removed as it is slanted, either blow
the air again with the protruding side pushed, or remove the pis-
ton using the needle nose plier with vinyl tape on the tip.
7. REMOVE INPUT SHAFT OIL SEAL RING
(a) Remove the input shaft oil seal ring to the input shaft.
8. INSTALL INPUT SHAFT OIL SEAL RING
(a) Compress the new input shaft oil seal ring from both sides
to reduce dimension A.
Dimension A: 5 mm (0.197 in.)
(b) Coat the oil seal ring with ATF and install it to the input
shaft.
NOTICE:
Do not expand the gap of the oil seal ring too much. Fix the
hooks certainly.
9. INSTALL FORWARD CLUTCH PISTON SUB−ASSY
(a) Coat the forward clutch piston with ATF, and install it to the
input shaft.

(b) Coat the clutch balancer with ATF.
(c) Install the clutch balancer to the input shaft.
NOTICE:
SBe careful not to damage the lip seal of the forward
clutch balancer.
SInstall the clutch balancer carefully not to have a
pinching and any other defects at the sealing lip.

bling.
(d) Place SST on the clutch balancer, and compress the
clutch balancer with a press.
SST 09387−00020
(e) Install the snap ring with a snap ring expander.
(f) Be sure the end gap of the snap ring is not aligned with
the spring retainer claw.
NOTICE:
SStop the press when the spring sheet is lowered to the
place1−2 mm (0.039−0.078 in.) from the snap ring
groove.
SThis prevents the spring sheet from being deformed.
SDo not expand the snap ring excessively.
