8.
Install coupling cover to gear carrier with arrow facing upward,
temporarily tighten reamer bolts to the positions shown in the
figure.
9.
Tighten reamer bolts and coupling cover mounting bolts to the
specified torque.
10. Install connector bracket, and tighten bolts to the specified
torque.
11. Install companion flange.
NOTE:
When reusing electric controlled coupling, align the matching
mark of electric controlled coupling with the matching mark of
companion flange, then install companion flange.
12. Install companion flange lock nut with flange wrench (commer-
cial service tool), tighten to the specified torque.
CAUTION:
Never reuse companion flange lock nut.
13. Check companion flange runout. Refer to
.

COMPANION FLANGE RUNOUT
1.
Fit a dial indicator onto the companion flange face (inner side of
the rear 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, replace companion flange.
c.
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 and electric controlled coupling, malfunctioning coupling bear-
ing, or malfunctioning of electric controlled coupling.
Inspection After Disassembly
INFOID:0000000001077000

Content
Conditions and Measures
Hypoid gear
• If the gear teeth do not mesh or line-up correctly, determine the cause and adjust or replace as nec-
essary.
• 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
If any chipped (by friction), pitted, worn, rusted or scratched mark, or unusual noise from the bearing is
observed, replace as a bearing assembly (as a new set).
Side gear and Pinion mate
gear
• 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
If it is chipped (by friction), damaged, or unusually worn, replace.
Differential case
If any wear or crack on the contact sides of the differential case is found, replace.
Companion flange
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.

DIFFERENTIAL ASSEMBLY
1.
Remove side oil seals, using flat-bladed screwdriver.
CAUTION:
Be careful not to damage gear carrier and rear cover.
2.
Remove rear cover mounting bolts.
3.
Set drifts (commercial service tool) to the right and left side bear-
ing adjusting shims individually. Press differential case assembly
with side bearing to remove gear carrier assembly and rear
cover assembly.
CAUTION:
The pressure shall be as low as possible to remove gear
carrier assembly and rear cover assembly. The maximum
pressure shall be 10 kN (1 ton, 1.0 Imp ton).
NOTE:
Differential case assembly, side bearings, and adjusting shims
are compressed and integrated in gear carrier and rear cover.
4.
Remove drain plug and filler plug.
5.
Remove side bearing adjusting shims and side bearing outer races.
CAUTION:
Mark the side bearing adjusting shims so that the original mounting positions (right/left) can be
identified later.
6.
Remove drive gear mounting bolts and then remove drive gear
from differential case.
7.
Remove side bearing inner races, using pullers and the drift
(SST: ST33052000).
