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.

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 (P1 ). Refer to TF-60, "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 a 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 gauge 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
