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-64, "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-74, "
Pinion Sleeve Assembly" .
4. Remove the plug on the upper side of the transfer case.
When installing plug, apply recommended sealant on screw
part, and tighten it at the specified torque. Refer to TF-59,
"COMPONENTS" .
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.Backlash : 0.13 - 0.19 mm (0.0051 - 0.0075 in)

6. If tooth contact is poorly adjusted, adjust pinion height (dimen-
sion X) in the following manner.

TRANSFER ASSEMBLY


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-77, "
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.
Refer to TF-77, "
Pinion Sleeve Shim" .
Pinion Bearing Preload Torque
1. Remove the pinion sleeve assembly. Refer to TF-64, "Pinion Sleeve Assembly" .
2. Rotate the companion flange back and forth 2 to 3 times. Check for unusual noise, rotation malfunction,
and other malfunctions.
3. Rotate the companion flange at least 20 times to check for smooth operation of the bearing.

4. Using the 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 (P1 ). Refer to TF-62, "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.Tool number : ST3127S000
