ASSEMBLY OF FORWARD CLUTCH
1. (A540E, A540H)
INSTALL OIL SEAL RINGS
Install the three oil seal rings (A540E) or two oil seal rings
(A540H) to the shaft.
NOTICE: Do not spread the ring ends more than necessary.
HINT: After installing the oil seal rings, check that they move
smoothly.

(a) Install the two new O±rings, to the piston. 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:
wIf the lining of the disc is exfoliated or discolored, or
even a part of the printed numbers are defaced, re-
place all discs.
wBefore assembling new discs, soak them in ATF for
at least fifteen minutes.
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. (A540H)

3. INSTALL PISTON RETURN SPRINGS
(a) Place the return spring 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)
(e) 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.
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 next page.
SST 09350±32014 (09351±32190)
Piston stroke: 1.41 ± 1.82 mm
(0.0555 ± 0.0717 in.) 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.
5. INSTALL SNAP RING
Check that the end gap of snap ring is not aligned with
one of the cutouts.(b) Coat the O±rings with ATF.
(c) Press the piston into the drum with the cup side
up, being careful not to damage the O±rings.

If the piston stroke is nonstandard, select another flange.
HINT: There are two different thicknesses for the flange.
Flange thickness: 3.00 mm (0.1181 in.)
3.37 mm (0.1327 in.)

DISASSEMBLY OF NO. 1 ONE±WAY CLUTCH
AND SUN GEAR
1. CHECK OPERATION OF NO. 1 ONE±WAY CLUTCH
Hold the sun gear and turn the hub. The hub should turn freely
clockwise and should lock counterclockwise.
2. REMOVE NO. 1 ONE±WAY CLUTCH FROM SUN
GEAR .
While turning the hub clockwise, remove the No. 1
one±way clutch from the sun gear.
Front Planetary Gear

A540H)AT±280

ASSEMBLY OF NO. 1 ONE±WAY CLUTCH
AND SUN GEAR
1. INSTALL SUN GEAR TO DRUM
(a) Install the sun gear to the drum.
(b) Using snap ring pliers, install the snap ring to drum. 5. CHECK SUN GEAR BUSHINGS
Using a dial indicator, measure the inside diameter of
the sun gear bushings.
Maximum inside diameter: 22.59 mm(0.8894 in.)
If the inside diameter is greater than the maximum, re-
place the sun gear. 4. REMOVE SUN GEAR FROM DRUM
(a) Using snap ring pliers, remove the snap ring from the
drum.
(b) Remove the sun gear from the drum. 3. REMOVE THRUST WASHER FROM SUN GEAR INPUT
DRUM
2. INSTALL THRUST WASHER TO SUN GEAR INPUT
DRUM

A540H)AT±281

INSPECTION OF PLANETARY RING GEAR
1. INSPECT RING GEAR FLANGE BUSHING
Using a dial indicator, measure the inside diameter of the
flange bushing.
Maximum inside diameter: 30.08 mm (1.1842 in.)
If the inside diameter is greater than the maximum, replace
the flange. 3. INSTALL NO. 1 ONE±WAY CLUTCH ON SUN GEAR
While turning the hub clockwise, slide the No. 1 one±
way clutch onto the sun gear.
4. RECHECK OPERATION OF NO. 1 ONE±WAY CLUTCH
2. REMOVE RING GEAR FLANGE
(a) Using a screwdriver, remove the snap ring.

MEASURE PLANETARY PINION GEAR THRUST
CLEARANCE
Using a feeler gauge, measure the planetary pinion gear
thrust clearance.
Standard clearance: 0.16 ± 0.56 mm
(0.0063 ± 0.0220 in.)
Maximum clearance: 0.61 mm
(0.0240 in.)
If the clearance is greater than the maximum, replace the plane-
tary gear assembly.
