7. Remove the front oil seal using Tool as shown.
INSTALLATION
1. Apply multi-purpose grease to the sealing lips of the new oil
seal, then press the front oil seal into the carrier using Tool as
shown.
CAUTION:

Keep the new oil seal even when installing, do not tilt the
oil seal when pressing it in.

Discard the old oil seal, always install a new oil seal.
2. Align the matching mark of the drive pinion with the matching
mark “B” of the companion flange as shown, then install the
companion flange.
3. Apply oil or multi-purpose grease on the drive pinion threads
and the seating surface of drive pinion nut.
4. Install new drive pinion nut using Tool.

Tighten the drive pinion nut to the minimum specified torque.
Final drive pinion nut torque will be determined when adjust-
ing the total preload. Refer to RFD-13, "
TOTAL PRELOAD" .
CAUTION:
The drive pinion nut is not reusable. Use a new drive pinion
nut for installation.
5. Install the rear propeller shaft. Refer to PR-9, "
INSTALLATION" .
6. Connect the rear drive shafts to the rear final drive. Tighten the drive shaft inside flange bolts to specifica-
tion.
7. Check the rear final drive fluid and add fluid as necessary. Refer to MA-25, "

8. Tighten the drive pinion nut by very small increments until the
specified preload is achieved, when checking the preload, turn
drive pinion in both directions several times.

If the pinion bearing preload is less than specification, tighten
the drive pinion nut.

If pinion bearing preload is greater than specification, replace
the pinion bearing adjusting spacer.
INSTALLATION OF DIFFERENTIAL CASE ASSEMBLY
1. Select the side bearing adjusting washer. Refer to RFD-19, "SIDE BEARING PRELOAD" .
2. Install the differential case assembly with side bearing outer
races into the gear carrier.
3. Insert the left and right side bearing adjusting washers into place
between the side bearings and the gear carrier.
4. Install the side bearing caps. Align the matching mark on the
bearing cap with the matching mark on the gear carrier, and
tighten the bearing cap bolts to specification.
5. Install the side oil seals. Refer to RFD-8, "
