CENTER STEM ASSEMBLY


Assembly






1. Press center stem to drive gear, using the drift (A) [SST:
ST33052000 ( -- )].





2. Press inner race of side bearing (right) to center stem assembly, using the drift (A) (Commercial service tool).

CAUTION:
- Never reuse side bearing.
- Apply gear oil to side bearing.





3. Press inner race of side bearing (left) to center stem assembly, using the drift (A) (Commercial service tool).

CAUTION:
- Never reuse side bearing.
- Apply gear oil to side bearing.
4. Install side bearing adjusting shims (2 pieces for right side) with the same thickness as the ones installed prior to disassembly or re-install the old ones, with outer race of side bearing to center stem assembly.
If side bearing adjusting shims have been already selected, use them.

CAUTION:
- Never reuse side bearing.
- Apply gear oil to side bearing.











5. Set the drifts (A and B) to the right and left side bearing adjusting shims individually. Press center stem assembly with side bearing to install gear carrier assembly to center stem assembly.

CAUTION:
- The drift shall be placed on the center of the adjusting shims.
- The pressure shall be as low as possible to install differential assembly into gear carrier assembly. The maximum pressure shall be 10 kN (1 ton, 1.0 Imp ton).
- If the adjusting shims are installed by tapping, the gear carrier may be damaged. Avoid tapping.
6. Install dummy cover set, check and adjust drive gear runout, tooth contact, backlash, and total preload torque. Adjustment.
7. Remove dummy cover set.





8. Apply liquid gasket (1) to mating surface of rear cover.
- Use Genuine Silicone RTV or equivalent. Recommended Chemical Products And Sealants, "Recommended Chemical Products and Sealants".

CAUTION:
- Remove old gasket adhering to the mounting surfaces.
Also remove any moisture, oil, or foreign material adhering to the mounting surfaces.
- The width of sealant bend is approximately 3 mm (0.012 in). Apply sealant evenly.











9. Set the drifts (A and B) to the right and left side bearing adjusting shims individually. Compress center stem assembly with side bearing to install rear cover.

CAUTION:
- The drift shall be placed on the center of the adjusting shims.
- The pressure shall be as low as possible to install the rear cover. The maximum pressure shall be 10 kN (1 ton, 1.0
Imp ton).
- If rear cover is forced in by tapping, rear cover may be damaged by adjusting shims. Avoid tapping.
10. Tighten rear cover mounting bolts to the specified torque.





11. Install side oil seal (right) until it becomes flush with the gear carrier end, using the drift (A) [SST: ST33400001 (J-26082)].

CAUTION:
- Never reuse oil seal.
- When installing, never incline oil seal.
- Apply multi-purpose grease onto oil seal lips, and gear oil onto the circumference of oil seal.





12. Install side oil seal (left) until it becomes flush with the gear carrier end, using the drift (A) [SST: KV38100500 ( -- )].

CAUTION:
- Never reuse oil seal.
- When installing, never incline oil seal.
- Apply multi-purpose grease onto oil seal lips, and gear oil onto the circumference of oil seal.
13. Set gasket to drain plug. Install it to gear carrier.

CAUTION:
Never reuse oil gasket.
14. Set gasket to filler plug. Install it to gear carrier.

CAUTION:
- Never reuse oil gasket.
- After oil is refilled, tighten filler plug to specified torque.
15. Install carrier brackets.
16. Install electric controlled coupling. Assembly.
17. Check total preload torque. Adjustment.





18. Install breather tube (1) and breathers (2) with the paint mark (A) facing vehicle rear within the angle (B) shown as follows.
