CAUTION:- Do not reuse the oil seal.
- When installing, do not incline oil seal.
- Apply multi-purpose grease onto oil seal lips, and gear oil onto the circumference of the oil seal.
- Install dust cover.NOTE:
Tighten dust cover together with pinion bearing assembly.
- Install companion flange (1) to pinion bearing using suitable tool (A).
- 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.
- Install pinion lock nut, and then tighten to the specified torque.
Pinion lock nut tightening torque : 90+-9 N•m (9.2+-0.92kg-m, 66+-7 ft-lb) CAUTION:- Do not reuse pinion lock nut.
- Check that pinion lock nut is seated on the companion flange.
- After tightening pinion lock nut to the specified torque, retighten the pinion lock nut by 25 degrees.
- Measure the pinion bearing preload.
Pinion bearing preload : Refer to PRELOAD TORQUE .
- Install pinion lock nut, and then tighten to the specified torque.
- Apply multi-purpose grease lightly and evenly onto an O-ring, and install it to the pinion bearing assembly.CAUTION:
- Do not reuse O-ring.
- When installing O-ring, do not use a suitable tool.
- Do not damage O-ring.
- Install drive pinion assembly, and apply anti-corrosive oil onto thread and seats on the mounting bolts. Tighten to the specified torque.
