DRIVE PINION
2.
Remove ring gear shaft assembly from transfer case. Then
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.
3.
Assemble the ring gear shaft assembly to the transfer case.
4.
Install adapter case. Refer to
5.
Remove plug on the lower side of the transfer case.
6.
Rotate the companion flange back and forth several times. Then
check drive pinion to ring gear tooth contact by viewing from the
tooth contact test hole. (A: Drive side, B: Reverse side)

7.
Follow the procedure below to adjust pinion height (dimension
X) if tooth contact is improper.
CAUTION:
If no adjusting shim with the calculated value is available,
select the thicker and closest one.
• Thicken the drive pinion adjusting shim to move the drive pin-
ion closer to the ring gear in case of face contact or heel con-
tact.
CAUTION:
Only one adjusting shim can be selected.
• Thin the drive pinion adjusting shim to move the drive pinion
farther from the ring gear in case of flank contact or toe con-
tact.
CAUTION:
Only one adjusting shim can be selected.
8.
Assemble the plug to the transfer case.
CAUTION:
• Remove old gasket on mounting surface, then remove
any moisture, oil, and foreign material on the application
and mounting surfaces.
• Apply liquid gasket to the thread, and tighten to the speci-
fied torque when installing plug.
DRIVE PINION BEARING PRELOAD
1.
Remove adapter case. Refer to
.
2.
Remove ring gear shaft assembly from the transfer case.
3.
Rotate the companion flange back and forth from 2 to 3 times to check for unusual noise, binding, sticking,
and so on.
4.
Rotate the companion flange at least 20 times to check for smooth operation of the bearing.
5.
Measure the drive pinion bearing preload with a preload gauge
(A) (SST: ST3127S000).
CAUTION:
Each rotational part should rotate smoothly with the speci-
fied gear oil.
• Disassemble the drive pinion assembly to check and adjust
each part if outside the standard.
TOTAL PRELOAD
1.
Measure drive pinion bearing preload (P
1
). Refer to “DRIVE PINION BEARING PRELOAD”.

DRIVE PINION
CAUTION:
Check that the drive pinion bearing preload is within the standard.
2.
Assemble the ring gear shaft assembly to the transfer case.
3.
Install adapter case. Refer to
4.
Rotate the companion flange at least 20 times to check for smooth operation of the bearing.
5.
Measure the total preload with a preload gauge (A) (SST:
ST3127S000).
CAUTION:
• Each rotational part should rotate smoothly with the spec-
ified gear oil.
• Disassemble the transfer assembly to check and adjust each part if outside the standard. Mea-
sure it with the adapter case oil seals removed when measuring total preload after disassembly.
Then install adapter case oil seals.
COMPANION FLANGE RUNOUT
1.
Fit a dial indicator onto the companion flange face (inner side of
the propeller shaft 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.
Follow the procedure below to adjust if runout value is outside
the repair limit.
CAUTION:
Replace collapsible spacer to check and adjust each part
when companion flange is adjusted or replaced.
a.
Check for runout while changing the phase between companion flange and drive pinion in 90
°
steps. Then
search for the minimum point.
b.
Replace companion flange if runout value is still outside the limit after the phase has been changed.
c.
Adjust assembly status of the drive pinion bearings and drive pinion, or replace drive pinion bearings if
runout is outside the standard after the companion flange is replaced.

• Measure dimension from transfer case mounting surface of
adapter case to adapter case edge surface with a pair of ver-
nier calipers and straightedge. Refer to “Measuring point”.
Dimension “B” measurement
• Measure dimension from ring gear adjusting shim mounting
surface of adapter case to adapter case edge surface with a
pair of vernier calipers and straightedge. Refer to “Measuring
point”.
