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

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
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, re-
place the flange.
2. REMOVE RING GEAR FLANGE
(a) Using a screwdriver, remove the snap ring.
(b) Remove the flange from the ring gear.
3. INSTALL RING GEAR FLANGE
(a) Position the flange into the ring gear.
(b) Using a screwdriver, install the snap ring.

DISASSEMBLY OF NO. 2 ONE-WAY CLUTCH
1. CHECK OPERATION OF NO. 2 ONE-WAY CLUTCH
Hold the outer race and turn the rear planetary gear.
The rear planetary gear should turn freely counter-
clockwise and should lock clockwise.
2. SEPARATE NO. 2 ONE-WAY CLUTCH AND REAR

3. REMOVE THRUST WASHERS
(A540E)
Remove the thrust washer from the rear side of plane-
tary gear.
(A540H)
Remove the two thrust washers from both sides of
planetary gear.

7. RECHECK PISTON STROKE OF DIRECT CLUTCH
Using a dial indicator, measure the piston stroke while
applying and releasing the compressed air (4 - 8 kg/
cm
2, 57 - 114 psi or 392 - 785 kPa) as shown.
Piston stroke: 1.75 - 2.49 mm
(0.0689 - 0.0980 in.)

DISASSEMBLY OF COUNTER DRIVE GEAR
1. CHECK OPERATION OF ONE-WAY CLUTCH
(a) Install the overdrive direct clutch into the one-way
clutch.
(b) Hold the overdrive direct clutch and turn the inter-
mediate shaft. The shaft should turn freely clock-
wise and should lock counterclockwise.
(c) Remove the overdrive direct clutch.
2. CHECK COUNTER DRIVE GEAR PRELOAD
(a) Hold the overdrive planetary gear in a vise with
soft jaws.
HINT: Do not let the counter drive gear touch the vise.
(b) Using a tension gauge, measure the preload.
Preload (at starting): 940 - 1,560 g
(2.1 - 3.4 lb, 9.2 - 15.3 N)
HINT: Turn the counter drive gear right and left several
times before measuring the preload.

11. INSTALL OVERDRIVE ONE-WAY CLUTCH AND
RETAINING PLATE
(a) Install the one-way clutch into the outer race.
(b) Install the two retainer on both sides of the one-
way clutch.
(c) Install the one-way clutch into the overdrive plane-
tary gear.
HINT: Be sure that the one-way clutch is installed in the
correct direction.
(d) Install the retaining plate.
(e) Install the snap ring.
12. CHECK OPERATION OF O/D ONE-WAY CLUTCH
(a) Install the overdrive direct clutch into the one-
way clutch.
(b) Hold the overdrive direct clutch and turn the in-
termediate shaft. The shaft should turn freely
clockwise and should lock counterclockwise.
(c) Remove the overdrive direct clutch.

(c) Turn the gear counterclockwise and clockwise sev-
eral times.
(d) Using a torque meter, measure the preload of the
drive pinion.
Drive pinion preload (at starting):
New bearing
10 - 16 kg-cm
(8.7 - 13.9 in.-lb, 1.0 - 1.6 N-m)
Reused bearing
5 - 8 kg-cm
(4.3 - 6.9 in.-lb, 0.5 - 0.8 N-m)
If the preload is greater than specified,
replace the bearing spacer.
If the preload is less than specified, retigh-
ten the nut 130 kg-cm (9 ft-lb, 13 N-m) at
a time until the specified preload is
reached.
If the maximum torque is exceeded while retightening the
nut, replace the bearing spacer and repeat the preload
procedure.
Do not back off the nut to reduce the preload.
Maximum torque: 3,600 kg-cm (260 ft-lb, 353 N-m)
(e) If the preload is adjusted within specification, make
a note of it.
(f) Stake the lock nut.
