Differential: Service and Repair

DISASSEMBLY
1. Using special tool, remove R bearing.
Special Tool
(A): 09913-65810 or equivalent.
(B): 09925-88210 or equivalent
2. Take out speedometer drive gear.

NOTE: In case that half-moon type puller is used with press for bearing removal, remove final gear in advance.

3. Remove L bearing by using puller while supporting its center shaft as described above.
4. Support differential case with soft jawed vise and remove eight final gear bolts then take out final gear.





5. Using special tool (C) 09922-85811 (4.5 mm) or equivalent, and hammer, drive out differential side pinion shaft pin and then disassemble component parts.

ADJUSTMENT AND REASSEMBLY

NOTE: Judging from abnormality noted before disassembly and what is found through visual check of component parts after disassembly, prepare replacing parts and proceed to reassembly. Make sure that all parts are clean.

1. Assemble differential gear and measure thrust play of differential gear as follows.
Special Tool:
(A): 09900-2060 or equivalent.
(B): 09900-20701 or equivalent.
Differential gear thrust play: 0.05 - 0.33 mm (0.002 - 0.013 inch).





Left Side
- Hold differential assembly with soft jawed vise and apply measuring tip of dial gauge to top surface of gear.
- Using two screwdrivers, move gear up and down and read movement of dial gauge pointer.





Right Side
- Using similar procedure to the above, set dial gauge tip to gear shoulder.
- Move gear up and down by hand and read dial gauge.





2. If thrust play is out of specification, select suitable thrust washer from among following available size, install it and check again that specified gear play is obtained.
3. Drive in spring pin from right side till it is flush with differential case surface.





4. Press-fit L bearing by using special tool and copper hammer.
Special Tool
(C): 09951-76010 or equivalent.
(D): 09951-16060 or equivalent.
5. Install speedometer drive gear, support differential assembly as illustrated so as to L bearing is floating, and then press-fit R bearing (like L bearing in Step 4).





6. Hold differential assembly with soft jawed vise, install final gear and then tighten it with eight bolts to 80 - 90 Nm (58.0 - 65.0 inch).

CAUTION Use of any other bolts than specified ones is prohibited.
