DRIVE PINION

Assembly

1.Select the pinion sleeve shim. Refer to "Adjustment" Adjustment.
Revision: March 20122013 Infiniti JX





2.Install the pinion rear bearing outer race with the drift (A) [SST:
KV38100300 (J-25523)].





3.Install the pinion front bearing outer race with the drifts (A and
B).










4.Install the pinion front bearing inner race to drive pinion with the drift (A) [SST: ST30901000 (J-26010-01)].

CAUTION:
- Apply gear oil to the pinion front bearing.
- Never reuse pinion front bearing.
5.Install a collapsible spacer to the drive pinion.

CAUTION:
Never reuse collapsible spacer.
6.Install the pinion rear bearing inner race to pinion sleeve.

CAUTION:
- Apply gear oil to the pinion rear bearing.
- Never reuse pinion rear bearing.





7.Install pinion sleeve oil seal to pinion sleeve with the drift (A)
[SST: ST33400001 (J-26082)].

CAUTION:
- Apply multi-purpose grease onto oil seal lips, and gear oil onto the circumference.
- Never reuse oil seal.
- Use the drift with larger diameter than outer diameter of oil seal.





8.Install companion flange to pinion sleeve assembly with the drift (A) [SST: ST33200000 (J-26082)].
9.Apply anti-corrosive oil to the thread and seat of the lock nut, and adjust the pinion lock nut tightening torque and pinion bearing preload torque, using a preload gauge.





Drive pinion bearing preload: Refer to DLN-94, "Preload Torque" Preload Torque.

CAUTION:
- Never reuse lock nut.
- If specified preload torque is exceeded, replace the collapsible spacer and tighten again. Never loosen the pinion lock nut for further preload torque adjustment.
10.Apply multi-purpose grease lightly and evenly onto an O-ring, and install it to the pinion sleeve.

CAUTION:
- Never reuse O-ring.
- When installing O-ring, never use a tool.
- Never damage the pinion sleeve.
11.Assemble the selected pinion sleeve shim.
12.Install the pinion sleeve assembly, and apply anti-corrosive oil onto thread and seats on the mounting bolts. Tighten to the specified torque. Refer to "Exploded View" Exploded View.
13.Check backlash, tooth contact, total preload and companion flange runout. Refer to "Adjustment" Adjustment.

CAUTION:
Measure the total preload without the adapter case oil seal.
