DRIVE PINION
2.
Select the proper pinion height adjusting washer.
If unable to find a washer of desired thickness, use a washer with thickness closest to the calculated
value.
PINION BEARING PRELOAD
Assemble the drive pinion parts if they are disassembled. Refer to
.
1.
Make sure all parts are clean. Also, make sure the bearings are well lubricated with gear oil.
2.
Install companion flange (1).
NOTE:
When reusing drive pinion, align the matching mark (B) of drive
pinion with the matching mark (A) of companion flange, and then
install companion flange (1).
3.
Temporarily tighten removed drive pinion lock nut to drive pinion.
NOTE:
Use removed drive pinion lock nut only for the preload measure-
ment.
4.
Rotate drive pinion at least 20 times to check for smooth opera-
tion of the bearing.
5.
Tighten to drive pinion lock nut, while adjust pinion bearing pre-
load torque.
CAUTION:
• Adjust to the lower limit of the drive pinion lock nut tight-
ening torque first.
• After adjustment, rotate drive pinion back and forth 2 to 3
times to check for unusual noise, rotation malfunction,
and other malfunctions.
6.
If the pinion bearing preload torque is outside the specification,
use a thicker/thinner drive pinion bearing adjusting washer and
drive pinion adjusting washer to adjust.

7.
Remove companion flange, after adjustment.
COMPANION FLANGE RUNOUT
1.
Fit a dial indicator onto the companion flange face (inner side of
the propeller shaft mounting bolt holes).
2.
Rotate companion flange to check for runout.
3.
Fit a test indicator to the inner side of companion flange (socket
diameter).
4.
Rotate companion flange to check for runout.
5.
If the runout value is outside the runout limit, follow the procedure below to adjust.
a.
Check for runout while changing the phase between companion flange and drive pinion by 90
°
step, and
search for the position where the runout is the minimum.
b.
If the runout value is still outside of the limit after the phase has been changed, possible cause will be an
assembly malfunction of drive pinion and pinion bearing and malfunction of pinion bearing. Check for
these items and repair if necessary.
c.
If the runout value is still outside of the limit after the check and repair, replace companion flange.

DRIVE GEAR AND DRIVE PINION
• Clean up the disassembled parts.
• If the gear teeth never mesh or line-up correctly, determine the cause and adjust or replace as necessary.
• If the gears are worn, cracked, damaged, pitted or chipped (by friction) noticeably, replace with new drive
gear and drive pinion as a set.
BEARING
• Clean up the disassembled parts.
• If any chipped (by friction), pitted, worn, rusted or scratched marks, or unusual noise from the bearing is
observed, replace as a bearing assembly (as a new set).
SIDE GEAR AND PINION MATE GEAR
• Clean up the disassembled parts.
• If any cracks or damage on the surface of the tooth is found, replace.
• If any worn or chipped mark on the contact sides of the thrust washer is found, replace.
SIDE GEAR THRUST WASHER AND PINION MATE THRUST WASHER
• Clean up the disassembled parts.
• If it is chipped (by friction), damaged, or unusually worn, replace.
OIL SEAL
• Whenever disassembled, replace.
When the preload torque is large:
Decrease the drive pinion bearing adjusting washer and drive pinion adjusting
washer thickness.For select parts refer to parts information.
When the preload is small:
Increase the drive pinion bearing adjusting washer and drive pinion adjusting
washer thickness.For select parts refer to parts information.

DRIVE PINION
• If wear, deterioration of adherence (sealing force lips), or damage is detected on the lips, replace them.
DIFFERENTIAL CASE
• Clean up the disassembled parts.
• If any wear or crack on the contact sides of the differential case is found, replace.
COMPANION FLANGE
• Clean up the disassembled parts.
• If any chipped mark [about 0.1 mm, (0.004 in)] or other damage on the contact sides of the lips of the com-
panion flange is found, replace.
