C50 MANUAL TRANSMISSION / TRANSAXLE DIFFERENTIAL CASE REASSEMBLY
PROCEDURE
41331F
1.INSTALL FRONT DIFFERENTIAL SIDE GEAR
Coat the sliding and rotating surfaces of the 2 front differential side gears and 2 front differential pinions with gear oil.
Install the 2 front No. 1 differential side gear thrust washers to the 2 front differential side gears.
Install the 2 front differential side gears, 2 front differential pinions, and 2 front differential pinion thrust washers to the front differential case.
- HINT:
-
While rotating each front differential side gear, install the 2 front differential pinions and 2 front differential pinion thrust washers.
41342F
2.INSTALL FRONT NO. 1 DIFFERENTIAL PINION SHAFT
Install the front No. 1 differential pinion shaft with gear oil.
Install the front No. 1 differential pinion shaft to the front differential case so that the hole for the front differential pinion shaft straight pin is aligned with the hole in the front differential case.
3.ADJUST FRONT DIFFERENTIAL SIDE GEAR BACKLASH
Hold the front differential pinion to the front differential case side. Using a dial indicator, measure the front differential side gear backlash.
- Standard Backlash:
0.05 to 0.20 mm (0.00197 to 0.00787 in.)
If the backlash is not as specified, replace the front No. 1 differential side gear thrust washers.
- Thrust Washer Thickness:
Parts No. Thickness mm (in.) 41361-22140 0.95 (0.0374) 41361-22020 1.00 (0.0394) 41361-22150 1.05 (0.0413) 41361-22030 1.10 (0.0433) 41361-22160 1.15 (0.0453) 41361-22040 1.20 (0.0472)
- HINT:
- ·
Measure the thickness with a micrometer to select a proper front No. 1 differential side gear thrust washer because the front No. 1 differential side gear thrust washers do not have any distinguishing marks.
·Select washers of the same thickness for both the right and left side.
41342A
4.INSTALL FRONT DIFFERENTIAL PINION SHAFT STRAIGHT PIN
Using a 3 mm pin punch and a hammer, install the front differential pinion shaft straight pin to the front differential case.
Using a chisel and hammer, stake the front differential case hole.
41221
5.INSTALL FRONT DIFFERENTIAL RING GEAR
Clean the contact surfaces of the front differential case and front differential ring gear.
Using a heater, heat the front differential ring gear to 90 to 110°C (194 to 230°F).
After moisture on the front differential ring gear has completely evaporated, quickly install the front differential ring gear to the front differential case.
| *a | Matchmark |
Aligning the matchmarks and quickly install the front differential ring gear to the front differential case.
Install the 8 bolts.
- Torque:
- 77.4 N*m (789 kgf*cm, 57 ft.*lbf)
- NOTICE:
-
Do not wash the bolts with an alkaline substance.

6.INSTALL SPEEDOMETER DRIVE GEAR
Install the speedometer drive gear to the front differential case.
