DRIVE PINION

4.

Install oil seal to pinion bearing assembly using suitable tool (A).

CAUTION:

• Never reuse the oil seal.
• When installing, never incline oil seal.
• Apply multi-purpose grease onto oil seal lips, and transfer

oil onto the circumference of the oil seal.

5.

Install dust cover.
NOTE:
Tighten dust cover together with pinion bearing assembly.

6.

Install companion flange

to pinion bearing using suitable tool

(A).

7.

Apply anti-corrosive oil to the thread and seat of the lock nut,
and adjust the pinion lock nut tightening torque and pinion bear-
ing preload torque, using a preload gauge.

a.

Install pinion lock nut, and then tighten to the specified torque.

CAUTION:

• Never reuse pinion lock nut.
• Check that pinion lock nut is seated on the companion flange.

b.

After tightening pinion lock nut to the specified torque, retighten the pinion lock nut by 25 degrees.

c.

Measure the pinion bearing preload.

8.

Apply multi-purpose grease lightly and evenly onto an O-ring, and install it to the pinion bearing assembly.

CAUTION:

• Never reuse O-ring.
• When installing O-ring, never use a suitable tool.
• Never damage O-ring.

9.

Install drive pinion assembly, and apply anti-corrosive oil onto
thread and seats on the mounting bolts. Tighten to the specified
torque.
NOTE:
Tighten dust cover together with pinion bearing assembly.

10. Check backlash, tooth contact, total preload and companion

flange runout. Refer to

DLN-88, "Adjustment"

.

CAUTION:

Measure the total preload without oil seals of transfer cover
and transfer case.

DRIVE PINION

• Check dimension (M) on the ring gear side face.

NOTE:
Dimension “M” indicates the difference between the optimum
engagement and standard dimensions in increments of 0.01 mm
(0.0004 in) written on the ring gear side face.

• Check dimension (O) on the gear end of drive pinion.

NOTE:
Dimension “O” indicates the difference between the optimum
engagement and the standard dimensions in increments of 0.01
mm (0.0004 in) written on the gear end of drive pinion.

PINION BEARING PRELOAD

CAUTION:

When measuring preload, the rotating speed must be set to 30 rpm.
1.

Remove ring gear shaft assembly from the transfer case. Refer to

DLN-83, "Disassembly"

.

2.

Rotate the companion flange back and forth from 2 to 3 times to check for unusual noise, binding, sticking,
and so on.

3.

Rotate the companion flange at least 20 times to check for smooth operation of the bearing.

4.

Measure the pinion bearing preload using Tool (A).

CAUTION:

Each rotational part should rotate smoothly with the speci-
fied transfer oil.
• If outside the standard, disassemble the drive pinion assembly

to check and adjust each part.

TOTAL PRELOAD

CAUTION:

When measuring preload, the rotating speed must be set to 30 rpm.
1.

Measure pinion bearing preload.

CAUTION:

Check that the pinion bearing preload is within the standard.

2.

Assemble the ring gear shaft assembly to the transfer case. Refer to

DLN-84, "Assembly"

3.

Install transfer cover to check and adjust each part. Refer to

DLN-80, "Assembly"

.

4.

Rotate the companion flange at least 20 times to check for smooth operation of the bearing.

5.

Measure the total preload using Tool (A).

CAUTION:

Each rotational part should rotate smoothly with the speci-
fied transfer oil.
• If outside the standard, disassemble the transfer assembly to

check and adjust each part. Measure it with the transfer case
oil seal and transfer cover oil seal removed when measuring
total preload after disassembly. Then install transfer case oil seals and transfer cover oil seal.

BACKLASH

1.

Install the bolt to the companion flange.

2.

Fit a dial indicator onto the bolt

.

3.

Measure the circumference backlash of the companion flange.

• If outside the standard, disassemble the transfer assembly to

check and adjust each part.

TOOTH CONTACT

1.

Remove transfer cover. Refer to

DLN-79, "Disassembly"

.

2.

Remove ring gear shaft assembly from transfer case. Refer to

DLN-83, "Disassembly"

.

3.

Apply red lead onto the ring gear.

CAUTION:

Apply red lead to both faces of 3 to 4 gears at 4 locations
evenly spaced on the ring gear.

4.

Assemble the ring gear shaft assembly to the transfer case.
Refer to

DLN-84, "Assembly"

.

5.

Install transfer cover to check and adjust each part. Refer to

DLN-80, "Assembly"

.

NOTE:
At this timing, O-ring installing to transfer cover is not necessary.
Install O-ring after backlash and tooth contact are checked.

6.

Remove the plug from the transfer case.

7.

Rotate the companion flange back and forth several times, and check the drive pinion gear to ring gear
tooth contact by viewing from the plug hole.
