4. 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.

5. Calculate the thickness of the ring gear bearing adjusting shim

(right) “T

” by the formula below.

NOTE:

Calculate dimension “C” as 56.0 mm (2.20 in)

6. Select ring gear bearing adjusting shim (right).

For selection adjusting shim, refer to the latest parts information.

CAUTION:

• Only one adjusting shim can be selected.

• Select the closest one, favoring thicker over thinner when necessary if no adjusting shim with

the calculated value is available.

Drive pinion adjusting shim

1. Measure the dimensions of each measuring point with the following procedure:

Dimension “L” measurement

• Measure dimension (L) from outer race edge surface of pinion

bearing (front) to inner race edge surface with depth gauge.

Refer to “Measuring point”.

Dimension “Q” measurement

• Measure dimension (Q) of transfer case with depth gauge and

straightedge. Refer to “Measuring point”.

CAUTION:

Never damage transfer case.

Dimension “R” measurement

= B

− C − D − H − I + (M / 100) + 0.045 mm (0.0018 in)

RING GEAR SHAFT

• Measure dimension (R

′) of transfer case (including the thick-

ness of straightedge) with a pair of vernier calipers and

straightedge. Refer to “Measuring point”.

CAUTION:

Never damage transfer case.

• Measure the thickness of straightedge.

• Calculate the dimension “R” by formula below.

Dimension “S” measurement

• Measure the diameter (S) of transfer case with a pair of vernier

calipers. Refer to “Measuring point”.

CAUTION:

Never damage transfer case.

2. Calculate dimension “J” by the formula below.

3. 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.

4. Calculate the thickness of the drive pinion adjusting shim “T

” by

the formula below.

NOTE:

Calculate dimension “K” as 70.85 mm (2.7894 in)

5. Select drive pinion adjusting shim.

For selection adjusting shim, refer to the latest parts information.

CAUTION:

• Only one adjusting shim can be selected.

• Select the closest one, favoring thicker over thinner when necessary if no adjusting shim with

the calculated value is available.

DRIVE PINION BEARING PRELOAD

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

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 drive pinion bearing preload with the preload

gauge (A) [SST: ST3127S000 (J-25765-A)].

CAUTION:

Each rotational part should rotate smoothly with the speci-

fied gear oil.

• If outside the standard, disassemble the drive pinion assembly

to check and adjust each part.

TOTAL PRELOAD

1. Measure drive pinion bearing preload.

CAUTION:

Check that the drive pinion bearing preload is within the standard.

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

DLN-98, "Assembly"

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

DLN-117, "Assembly"

CAUTION:

Never apply liquid gasket.

4. Rotate the companion flange at least 20 times to check for smooth operation of the bearing.
5. Measure the total preload with the preload gauge (A) [SST:

ST3127S000 (J-25765-A)].

CAUTION:

Each rotational part should rotate smoothly with the speci-

fied gear oil.

• If outside the standard, disassemble the transfer assembly to

check and adjust each part. Measure it with the transfer case

oil seals removed when measuring total preload after disas-

sembly. Then install transfer case oil seals.

6. Reinstall transfer cover for applying liquid gasket. Refer to

DLN-117, "Assembly"

BACKLASH

1. Install the bolt to the companion flange.
2. Fit a dial indicator onto the bolt (A).
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-117, "Disassembly"

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

DLN-97, "Disassembly"

RING GEAR SHAFT

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-98, "Assembly"

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

DLN-117, "Assembly"

CAUTION:

Never apply liquid gasket.

6. Rotate the companion flange back and forth several times.
7. Remove ring gear shaft assembly from transfer case. Then check drive pinion to ring gear tooth contact

Tooth Contact Judgment Guide

8. Follow the procedure below to adjust pinion height (dimension

X) if tooth contact is improper. For selecting adjusting shim, refer

to the latest parts information.

CAUTION:

If no adjusting shim with the calculated value is available,

select the thicker and closest one.
