ASSEMBLY INSPECTION
Backlash

1.

Install a bolt to the companion flange.

2.

Fit a dial indicator onto the bolt.

3.

Measure the circumference backlash of the companion flange,
and make sure it satisfies the standard below.

●

If measured value is out of the specification, disassemble it to
check and adjust each part.

Tooth Contact

1.

Remove the pinion sleeve assembly. Refer to 

TF-59, "Pinion Sleeve Assembly"

 .

2.

Apply red lead to the drive gear.

CAUTION:

Apply red lead to both the faces of 3 to 4 gears at 4 loca-
tions evenly spaced on the drive gear.

3.

Install the pinion sleeve shims and pinion sleeve assembly.
Refer to 

TF-69, "Pinion Sleeve Assembly"

 .

4.

Remove the plug on the upper side of the transfer case.
When installing plug, apply sealant on screw part, and tighten it
at the specified torque. Refer to 

TF-54, "COMPONENTS"

 .

●

Use Genuine Silicone RTV or equivalent. Refer to 

GI-47,

"Recommended Chemical Products and Sealants"

 .

5.

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

If the tooth contact is near the face (face contact), or near the
heal (heel contact), thin the pinion sleeve shims to move the
drive pinion closer to the drive gear.
Refer to 

TF-72, "Pinion Sleeve Shim"

 .

●

If the tooth contact is near the flank (flank contact), or near the
toe (toe contact), thicken the pinion sleeve shims to move the
drive pinion farther from the drive gear.

4.

Using a preload gauge, measure the preload torque of the pin-
ion bearing.

CAUTION:

Every rotational part shall rotate smoothly with the speci-
fied gear oil.

●

If measured value is out of the specification, disassemble the
pinion sleeve assembly to check and adjust each part.

Total Preload Torque

1.

Measure pinion bearing preload torque (P

1

 ). Refer to 

TF-57, "Pinion Bearing Preload Torque"

 .

2.

Install the pinion sleeve shims and pinion sleeve assembly.

3.

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

4.

Using the preload gauge, measure the total preload torque.

●

If measured value is out of the specification, disassemble it to
check and adjust each part. If measuring the total preload
torque after the disassembly, measure it with the transfer case oil seals and gear ring oil seals
removed, then install the oil seals.

Companion Flange Runout

1.

Fit a dial indicator onto the companion flange face (inner side of
the propeller shaft mounting bolt holes).

2.

Rotate the companion flange to check for runout.

3.

Fit a test indicator to the inner side of the companion flange
(socket diameter).

4.

Rotate the companion flange to check for runout.

5.

If the runout value is outside the repair limit, follow the procedure
below to adjust.

a.

While changing the phase between companion flange and drive pinion gear by 90

°

 at a time, check runout

and determine which phase angle minimizes the runout.

b.

If the runout value is still outside of the limit after the phase has been changed, replace the companion
flange.

c.

If the runout is out of the specification after replacement of companion flange, adjust the assembly status
of the pinion bearings and drive pinion gear, or replace the pinion bearings.

2.

Install the oil gutter.

3.

Using the drifts, install the selected gear ring bearing adjusting
shim (adapter case side) and gear ring bearing outer race
(adapter case side).

4.

Using the drift, drive the adapter case oil seal until it becomes
flush with the case end.

CAUTION:

●

When checking the total preload torque, measure it with-
out the oil seal, then install the oil seal.

●

Do not reuse the oil seal.

●

Apply multi-purpose grease onto oil seal lips, and gear
oil onto the circumference of the oil seal.

5.

Apply sealant on drain plug and install it to the adapter case.
Refer to 

TF-54, "COMPONENTS"

 .

●

Use Genuine Silicone RTV or equivalent. Refer to 

GI-47, "Recommended Chemical Products and

Sealants"

 .

6.

Apply multi-purpose grease lightly and evenly onto an O-ring, and install it to the adapter case.

CAUTION:

Do not reuse the O-ring.

7.

Install the adapter case to the transfer case, and apply anti-cor-
rosive oil onto threads and seats on the mounting bolts. Tighten
to the specified torque.

8.

Check backlash, preload torque, tooth contact, and companion
flange runout. Refer to 

TF-55, "ASSEMBLY INSPECTION"

 .

CAUTION:

Measure the total preload torque without the oil seal.

Pinion Sleeve Assembly

1.

Select the pinion sleeve shim. Refer to 

TF-64, "SELECTING ADJUSTING SHIMS"

 .

2.

Install dust cover.

3.

Using the drift, install the pinion rear bearing outer race.

4.

Using the drifts, install the pinion front bearing outer race.

5.

Apply gear oil to pinion front bearing inner race and mating posi-
tion on the drive pinion. Using the drift, install pinion front bear-
ing inner race to the drive pinion.

6.

Install a collapsible spacer to the drive pinion.

CAUTION:

Do not reuse the collapsible spacer.

7.

Apply gear oil to pinion rear bearing inner race and install it to
the pinion sleeve.

8.

Using the drift, install pinion sleeve oil seal to the pinion sleeve.

CAUTION:

●

Do not reuse the oil seal.

●

Apply multi-purpose grease onto oil seal lips, and gear
oil onto the circumference of the oil seal.

9.

Using the drift and press in the companion flange.

10. Apply anti-corrosion oil onto threads and seat of the pinion lock

nut and adjust the pinion lock nut tightening torque and pinion
bearing preload torque (P’

1

 ), using a preload gauge.

CAUTION:

●

Do not reuse the pinion lock nut.

●

Adjust the lower limit of the pinion lock nut tightening torque first.

●

While confirming the preload torque, tighten pinion lock nut by 5

°

 to 10

°

. Because preload will

increase suddenly.

●

If specified preload torque is exceeded, replace the collapsible spacer and tighten again. Never
loosen the pinion lock nut for further preload torque adjustment.

●

After the adjustment, rotate the companion flange back and forth 2 to 3 times to check for
unusual noise, rotation malfunction, and other malfunctions.

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

CAUTION:

Do not reuse the old O-ring.

12. Assemble the selected pinion sleeve shim.

13. Install the pinion sleeve assembly, and apply anti-corrosive oil onto threads and seats on the mounting

bolts. Tighten to the specified torque. Refer to 

TF-54, "COMPONENTS"

 .

14. Check backlash, preload torque, tooth contact and companion flange runout. Refer to 

TF-55, "ASSEMBLY

INSPECTION"

 .

The total preload torque is as follows:
