REAR FINAL DRIVE ASSEMBLY
11. Temporarily tighten reamer bolts (1) to the positions shown in
the figure.
CAUTION:
• Never use tools. Always tighten by hand.
• If reamer bolts cannot be tightened all the way by hand,
the electric controlled coupling pin may not be positioned
in the groove of the final drive assembly. In this case,
remove electric controlled coupling and reinstall it.
12. Tighten reamer bolts and coupling cover mounting bolts to the
specified torque.
13. Install harness bracket, and tighten bolts to the specified torque.
14. Install torsional damper. (When torsional damper has been
reused.)
CAUTION:
Clean the mounting surface.
15. Install torsional damper. (When torsional damper has been replaced.)
Degrease the mounting surface of electric controlled coupling, according to the following instruction.
1. Spray alcohol on a cotton cloth four times per part.
CAUTION:
Always use a new cotton cloth.
2. Wipe the mounting surface of electric controlled coupling
five times.
CAUTION:
Complete the work within 180 seconds to prevent alco-
hol from evaporating.
16. Install torsional damper mounting nut, using flange wrench (1)
(commercial service tool) and tighten to the specified torque.
CAUTION:
Never reuse torsional damper mounting nut.
17. Check companion flange runout. Refer to
18. When oil leaks while removing, check oil level after installation.
.
19. When replacing electric controlled coupling, perform writing unit
characteristics after installing final drive assembly to the vehicle.

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 electric controlled coupling.
Inspection
INFOID:0000000009177831
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.
