DRAINING

1. Stop the engine.
2. Remove the drain plug and gasket from the front final drive

assembly to drain the differential gear oil.

3. Install the drain plug with a new gasket to the front final drive

assembly. Tighten to the specified torque. Refer to

DLN-359,

"Disassembly and Assembly"

CAUTION:

Do not reuse gasket.

FILLING

1. Remove the filler plug and gasket from the front final drive

assembly.

2. Fill the front final drive assembly with new differential gear oil

until the level reaches the specified level near the filler plug hole.

3. Install the filler plug with a new gasket on it to the front final drive assembly. Tighten to the specified

torque. Refer to

DLN-359, "Disassembly and Assembly"

CAUTION:

Do not reuse gasket.

Checking Differential Gear Oil

INFOID:0000000006245178

DIFFERENTIAL GEAR OIL LEAKAGE AND LEVEL

1. Make sure that differential gear oil is not leaking from the front final drive assembly or around it.
2. Check the differential gear oil level from the filler plug hole as

shown.

CAUTION:

Do not start engine while checking differential gear oil level.

3. Install the filler plug with a new gasket on it to the front final drive

assembly. Tighten to the specified torque. Refer to

DLN-359,

"Disassembly and Assembly"

CAUTION:

Do not reuse gasket.

REMOVAL

NOTE:

When removing components such as hoses, tubes/lines, etc., cap or plug openings to prevent fluid from spill-

ing.
1. Remove the drive shafts from the front final drive assembly. Refer to

RAX-8, "Removal and Installation"

2. Remove the front propeller shaft from the front final drive assembly. Refer to

DLN-318, "Removal and

Installation"

3. Measure the total preload torque. Refer to

DLN-359, "Disassembly and Assembly"

NOTE:

Record the total preload torque measurement.

4. Remove the drive pinion lock nut using suitable tool.
5. Put matching marks on the companion flange and drive pinion

using paint.

CAUTION:

Use paint to make the matching marks. Do not damage the

companion flange or drive pinion.

6. Remove the companion flange using suitable tool.

FRONT OIL SEAL

DLN-353

< REMOVAL AND INSTALLATION >

[FRONT FINAL DRIVE: R180A]

DLN

1. Apply multi-purpose grease to the lips and differential gear oil to

the circumference of the new front oil seal. Then drive the new

front oil seal in evenly until it becomes flush with the gear carrier

using Tools.

CAUTION:

• Do not reuse front oil seal.

• Do not incline the new front oil seal when installing.

• Apply multi-purpose grease to the lips and differential

gear oil to the circumference of the new front oil seal.

2. Install the companion flange to the drive pinion while aligning the matching marks.
3. Apply anti-corrosive oil to the threads of the drive pinion and the

seating surface of the new drive pinion lock nut. Then adjust the

drive pinion lock nut tightening torque using suitable tool A, and

check the total preload torque using Tool B.

• The total preload torque should be within the total preload

torque specification. When not replacing the collapsible

spacer, it should also be equal to the measurement taken dur-

ing removal plus an additional 0.56 N·m (0.06 Kg-m, 5 in-lb).

• If the total preload torque is low, tighten the drive pinion lock

nut in 6.8 N·m (0.69 Kg-m, 5ft-lb) increments until the total pre-

load torque is met.

CAUTION:

• Do not reuse drive pinion lock nut.
