b. Using a screwdriver, remove the snap ring from the ring gear.
3. REMOVE REAR PLANETARY GEAR ASSEMBLY FROM OUTPUT SHAFT





a. Pull out the rear planetary gear assembly.





b. Remove the bearing and race.





4. REMOVE REAR PLANETARY CARRIER AND ASSEMBLED THRUST WITH RACE BEARING AND RACE FROM PLANETARY RING GEAR
5. REMOVE PLANETARY RING GEAR





a. Using a screwdriver, remove the set ring.





b. Remove the planetary ring gear.





c. Remove the race from the ring gear.





6. REMOVE OIL SEAL RING FROM INTERMEDIATE SHAFT
Using a screwdriver, remove the oil seal ring.





7. REMOVE OIL SEAL RINGS FROM OUTPUT SHAFT
Remove the 3 oil seal rings.

Rear Planetary Gear And Output Shaft Inspection





1. CHECK OUTPUT SHAFT BUSHING
Using a dial indicator, measure the inside diameter of the output shaft bushing.

Maximum inside diameter: 18.08 mm (0.7118 inch)

If the inside diameter is greater than the maximum, replace the output shaft.





2. MEASURE PLANETARY PINION GEAR THRUST CLEARANCE
Using a feeler gauge, measure the planetary pinion gear thrust clearance.

Standard clearance: 0.20 - 0.50 mm (0.0079 - 0.0197 inch)

If the clearance is non-standard, inspect the planetary gear thrust washer. If necessary, replace the planetary gear assembly.

Rear Planetary Gear And Output Shaft Assembly





1. INSTALL OIL SEAL RINGS
a. Coat the 3 oil seal rings with Automatic Transmission Fluid (ATF).
b. Install the oil seal rings to the output shaft, then snug them down by squeezing their ends together.

NOTICE: Do not spread the ring ends too much.

HINT: After installing the oil seal rings, check that they rotate smoothly.





2. INSTALL NEW OIL SEAL RING
Coat a new oil seal ring with ATF and install It to the intermediate shaft.

NOTICE: Do not spread the ring too much.

HINT: After installing the oil seal ring, check that it rotates smoothly.

3. INSTALL PLANETARY RING GEAR





a. Coat the race with petroleum jelly and install it onto the intermediate shaft.





Race diameter





b. Install the ring gear to the intermediate shaft.





c. Install the set ring.





4. INSTALL ASSEMBLED THRUST WITH RACE BEARING AND REAR PLANETARY CARRIER TO PLANETARY RING GEAR
5. INSTALL REAR PLANETARY GEAR ASSEMBLY TO OUTPUT SHAFT





a. Coat the bearing and race with petroleum jelly and install them onto the ring gear.





Bearing and race diameter





b. install the rear planetary gear assembly to the output shaft.
6. INSTALL FRONT PLANETARY RING GEAR





a. Install the snap ring.
b. Align the snap ring end with the wide cutout portion of the output shaft.





c. Using a snap ring expander, install the ring gear while compressing the snap ring.
d. Check that the snap ring is installed into the groove of the output shaft.





7. INSTALL THRUST WASHER
a. Coat the thrust washer with petroleum jelly.
b. Install the thrust washer onto the rear planetary carrier.

HINT: Make sure that the lug shapes match the cutout portions on the rear planetary carrier.
