Reduction Driven Gear
Reduction Driven GearREMOVAL
1. Remove the transmission assembly from vehicle.
2. Remove the rear vehicle speed sensor, and then separate the extension case and intermediate case from transmission case.
3. Remove the center differential carrier.
4. Set the select lever to P range.
5. Using the ST1 and ST2, extract the reduction driven gear.
ST1 499737100 PULLER SET
ST2 18680AA000 GEAR HOLDER
INSTALLATION
1. Set the select lever to P range.
2. Use a plastic hammer to install reduction driven gear assembly.
3. Select the reduction gear shim.
4. Connect the transmission case, extension case and intermediate case, and install the rear wheel speed sensor.
5. Install the transmission assembly into vehicle.
DISASSEMBLY
1. Remove the ball bearing from reduction driven gear using ST.

2. Remove the ball bearing on reverse side with the same procedure in step 1).
3. Remove the snap ring from reduction driven gear.
ASSEMBLY
1. Install the snap ring to reduction driven gear.
2. Install the new ball bearing to reduction driven gear using press.
3. Install the ball bearing on reverse side with the same procedure in step 2).
INSPECTION
Make sure the ball bearing and gear are not deformed or damaged.
ADJUSTMENT
1. Using depth gauge, measure depth A from mating surface of extension case to ball bearing on rear end of reduction driven gear.
2. Using a depth gauge, measure the height B from mating surface of extension case to ball bearing inside low part of extension case.
3. Calculation formula:
Select the ball bearing from the table to adjust clearances within 0.05 - 0.25 mm (0.0020 - 0.098 inch).
When clearances are 0.05 mm (0.0020 inch):
T (mm)=A-B+0.23
[T (in) = A - B + 0.0091]
When clearances are 0.25 mm (0.0098 inch):
T (mm) = A- B + 0.03
[T (in) = A - B +0.0011]
T: Shim clearance
A: Depth from mating surface of extension case to ball bearing outer ring end surface
B: Height from mating surface of extension case to ball bearing inside low part.
