ing must protrude. Refer to EM-244, "
ASSEMBLY" for the
tightening procedure.

If the standard is not met, replace main bearings.

Installation Drive Pinion AssemblyADS000NP
1. Press-fit the drive pinion bearing outer race into the carrier case
with tool.
CAUTION:
First lightly tap outer race using a hammer, place the carrier
case and outer race parallel. Then press-fit outer race with
press.
2. Temporarily install the removed drive pinion height adjusting
washer or same thickness washer to drive pinion.
3. If the hypoid gear set has been replaced, select the adjusting
washer.
Temporarily install washer to the drive pinion.
CAUTION:
Select the washer form the drive pinion height adjusting washer selecting table. Refer to FFD-38,
"AVAILABLE PINION HEIGHT ADJUSTING WASHERS" .
4. Press-fit the drive pinion bearing onto the drive pinion using drift
and press.
NOTE:
Note the direction of washer.
5. Install the drive pinion and drive pinion bearing as follows:
a. Apply gear oil to the bearing portion.
b. Install the drive pinion and drive pinion bearing (front side) into
the carrier case.Tool number : KV31103000 ( – )

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
