Never reuse pinion bearing.
5. Assemble collapsible spacer (1) to drive pinion (2).
CAUTION:
• Be careful of the mounting direction of collapsible spacer.
• Never reuse collapsible spacer.
6. Assemble drive pinion into gear carrier.
CAUTION:
Apply gear oil to pinion bearing.
7. Assemble inner race of pinion bearing (front) to drive pinion
assembly.
CAUTION:
• Never reuse pinion bearing.
• Apply gear oil to pinion bearing.
8. Using the drift (A) [SST: KV37710000 (
—
)], press the
inner race of pinion bearing (front) to drive pinion as far as drive
pinion nut can be tightened.
9. Using the drift (A) (Commercial service tool), drive front oil seal
until it becomes flush with the gear carrier end.
CAUTION:

DRIVE PINION
10. Install companion flange.
NOTE:
When reusing drive pinion, align the matching mark (A) of drive
pinion with the matching mark (B) of companion flange (1), and
then install companion flange.
11. Apply anti-corrosion oil to the thread and seat of drive pinion
lock nut, and temporarily tighten drive pinion lock nut to drive
pinion, using the flange wrench (Commercial service tool).
CAUTION:
Never reuse drive pinion lock nut.
12. Adjust to the drive pinion lock nut tightening torque and pinion
bearing preload torque, using the preload gauge (A) [SST:
ST3127S000 (J-25765-A)].
CAUTION:
• Adjust to the lower limit of the drive pinion lock nut tight-
ening torque first.
• If the preload torque exceeds the specified value, replace
collapsible spacer and tighten it again to adjust. Never
loosen drive pinion lock nut to adjust the preload torque.
• After adjustment, rotate drive pinion back and forth 2 to 3
times to check for unusual noise, rotation malfunction,
and other malfunctions.
13. Install center stem assembly. Refer to
.
CAUTION:
Never install rear cover at this timing.
14. Check and adjust drive gear runout, tooth contact, drive gear to drive pinion backlash, and companion
flange runout. Refer to
15. Check total preload torque. Refer to
.
16. Install rear cover. Refer to
17. Install electric controlled couplings. Refer to

1. Use the formula below to calculate drive pinion adjusting shim
thickness.
2. Select the proper drive pinion adjusting shim. For selecting adjusting shim, refer to the latest parts infor-
mation.
CAUTION:
If unable to find a shim of desired thickness, use a shim with thickness closest to the calculated
value.
COMPANION FLANGE RUNOUT
Check for companion flange runout as follows:
• For companion flange face, fit a dial indicator (1) onto the compan-
ion flange face (inner side of the propeller shaft mounting bolt
holes). For inner side of the companion flange, fit a test indicator
(2) to the inner side of companion flange (socket diameter).
• Rotate companion flange to check for runout.
• If the runout value is outside the runout limit, follow the procedure
below to adjust.
- 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.
- If the runout value is still outside of the limit after the phase has been changed, replace companion flange.
- If the runout value is still outside of the limit after companion flange has been replaced, possible cause will
be an assembly malfunction of drive pinion.

INSPECTION AFTER DISASSEMBLY
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.

DRIVE PINION
• Whenever disassembled, replace.
• 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).
Oil Seal
• Whenever disassembled, replace.
• If wear, deterioration of adherence (sealing force lips), or damage is detected on the lips, replace them.
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.
