Installation Drive Pinion Assembly: Notes
- Press-fit the drive pinion bearing outer race into the carrier case with tool.
Tool number: KV31103000 (-)
CAUTION: First lightly tap outer race using a hammer, place the carrier case and outer race parallel. Then press-fit outer race with press. - Temporarily install the removed drive pinion height adjusting washer or same thickness washer to drive pinion.
- If the hypoid gear set has been replaced, select the adjusting washer.
Washer selection equation:
T = T0 + (t1 -t2)
T = Correct washer thickness
T0 = Removed washer thickness
t1 = Old drive pinion head letter (machined tolerance 1/100 mm x 100)
t2 = New drive pinion head letter (machined tolerance 1/100 mm x 100)
Example:
In case the T0 = 3.21, t1 = +2, t2 = -1
T = 3.21 + ((2 x 0.01) - (-1 x 0.01)) = 3.24
Temporarily install washer to the drive pinion.
CAUTION: Select the washer form the drive pinion height adjusting washer selecting table. Refer to AVAILABLE PINION HEIGHT ADJUSTING WASHERS . - Press-fit the drive pinion bearing onto the drive pinion using drift and press.
Tool number: ST30032000 (-)
NOTE: Note the direction of washer. - Install the drive pinion and drive pinion bearing as follows:
- Apply gear oil to the bearing portion.
- Install the drive pinion and drive pinion bearing (front side) into the carrier case.

CAUTION: Do not install the drive pinion adjusting washer and drive pinion bearing adjusting washer at this time. - Install the companion flange without installing oil seal.
- Apply oil drive pinion lock nut threads and seating surface, then temporarily install it.
- Tighten the drive pinion lock nut until it reach standard preload.
Tool number: KV40104000 (-)
Pinion bearing preload without oil seal
: 0.78 - 1.57 N.m (0.08 - 0.16 kg-m, 7 - 13 in-lb)
CAUTION: Tighten the drive pinion nut by very small degrees until the specified preload in achieved. Do not tighten nut more than necessary.
