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.
(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.

INSPECTION OF FRONT PLANETARY GEAR
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.

DISASSEMBLY OF SECOND BRAKE
PISTON
REMOVE SECOND BRAKE PISTON
(a) Apply compressed air to the oil hole to remove the
piston.
(b) Remove the two O±rings from the piston.

INSPECTION OF SECOND BRAKE
COMPONENT
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, replace
all discs.
wBefore assembling new discs, soak them in ATF for at
least fifteen minutes.
ASSEMBLY OF SECOND BRAKE PISTON
INSTALL PISTON
(a) Coat a new O±ring with ATF.
(b) Install the two O±rings on the piston.
(c) Press the piston into the drum, being careful not
to damage the O±rings.

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

INSPECTION OF REAR PLANETARY
GEAR
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 planetary gear assembly. 4. REMOVE NO. 2 ONE±WAY CLUTCH FROM OUTER
RACE .
(a) Remove the two snap rings and retainers from both
sides.
(b) Remove the No. 2 one±way clutch from the outer race.
ASSEMBLY OF NO. 2 ONE±WAY
CLUTCH
1. INSTALL ONE±WAY CLUTCH
(a) Install the No. 2 one±way clutch into the outer race,
facing the flanged side of the No. 2 one±way clutch
toward the shiny side of the outer race.
(b) Install the two retainers and snap rings to both sides.

4. INSTALL THRUST WASHERS
(A540E)
(a) Coat the thrust washer with petroleum jelly.
(b) Align the tab of the washer with the hollows of the carrier.
(A540H)
(a) Coat the two thrust washers with petroleum jelly.
(b) Align the tab of the washer with the hollows of the carrier. 2. INSTALL PLANETARY GEAR INTO NO. 2 ONE±WAY
CLUTCH
Install the planetary gear into the No. 2 one±way
clutch, facing the inner race of the rear planetary gear
toward the black side of the No. 2 one±way clutch out-
er race.
REPLACEMENT OF RING GEAR FLANGE
