Drive Pinion: Assembly
- Select the pinion sleeve shim. Refer to "ADJUSTMENT ".
- Install the pinion rear bearing outer race with the drift (A) [SST: KV38100300 (J-25523)].
- Install the pinion front bearing outer race with the drifts (A and B).
- 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.
- Install a collapsible spacer to the drive pinion.CAUTION: Never reuse collapsible spacer.
- Install the pinion rear bearing inner race to pinion sleeve.CAUTION:
- Apply gear oil to the pinion rear bearing.
- Never reuse pinion rear bearing.
- 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.
- Install companion flange to pinion sleeve assembly with the drift (A) [SST: ST33200000 (J-26082)].
- 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.
Standard
Drive pinion lock nut tighten torque: 128 - 294 N.m (13 - 29 kg-m, 95 - 216 ft-lb)
Drive pinion bearing preload: Refer to "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.
- 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.
- Assemble the selected pinion sleeve shim.
- 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 ".
- Check backlash, tooth contact, total preload and companion flange runout. Refer to
"ADJUSTMENT ".CAUTION: Measure the total preload without the adapter case oil seal.
