•
Drive pinion front bearing;
make sure the J-34309-3 drive
pinion front bearing seat is secured tightly against the J-
34309-2 gauge anvil. Then turn the J-34309-7 drive pinion
front bearing pilot to secure the drive pinon front bearing in its
proper position.
•
Drive pinion rear bearing;
the J-34309-8 drive pinion rear
bearing pilot is used to center the drive pinion rear bearing
only. The J-34309-4 drive pinion rear bearing locking seat is
used to lock the drive pinion rear bearing to the assembly.
•
Installation of J-34309-9 and J-34309-16;
place a suitable
2.5 mm (0.098 in) thick plain washer between J-34309-9 and
J-34309-16. Both surfaces of J-34309-9 and J-34309-16 must
be parallel with a clearance of 2.5 mm (0.098 in).
3. Install the drive pinion rear bearing inner race into the gear car-
rier. Then insert the drive pinion height adjusting washer selec-
tor tool, J-34309-1, gauge screw assembly.
4. Assemble the drive pinion front bearing inner race and the J-
34309-2 gauge anvil. Assemble them together with the J-34309-
1 gauge screw in the gear carrier. Make sure that the drive pin-
ion height gauge plate, J-34309-16, will turn a full 360
°
. Tighten
the two sections together by hand.
5. Turn the assembly several times to seat the drive pinon bear-
ings.

6. Measure the turning torque at the end of the J-34309-2 gauge
anvil using Tool.
7. Place the J-34309-10 “R180A” drive pinion height adapter onto
the gauge plate and tighten it by hand.
CAUTION:
Make sure all machined surfaces are clean.
8. Position the side bearing discs, Tool, and arbor firmly into the
side bearing bores. Install the side bearing caps and tighten the
side bearing cap bolts to the specified torque. Refer to
9. Select the correct standard drive pinion height adjusting washer
thickness. Select by using a standard gauge of 3 mm (0.12 in)
and your J-34309-101 feeler gauge. Measure the distance
between the J-34309-10 drive pinion height adapter, including
the standard gauge and the arbor.
10. Write down the exact measurement (the value of feeler gauge).

11. Correct the drive pinion height adjusting washer size by referring
to the drive pinion “head number”.
There are two numbers painted on the drive pinion. The first
one refers to the drive pinion and drive gear as a matched
set. This number should be the same as the number on the
drive gear. The second number is the drive pinion “head
number”. It refers to the ideal drive pinion height from stan-
dard for quietest operation. Use the following chart to
determine the correct drive pinion height adjusting washer.
12. Select the correct drive pinion height adjusting washer. Refer to
DLN-374, "Inspection and Adjustment"
13. Remove the Tool from the gear carrier and disassemble to
retrieve the drive pinion bearings.

race.
2. Select drive pinion height adjusting washer. Refer to
DLN-374, "Inspection and Adjustment"
.
3. Install the selected drive pinion height adjusting washer to the
drive pinion. Press the drive pinion rear bearing inner race to it
using Tool.
CAUTION:
• Install the drive pinion height adjusting washer in the
proper direction as shown.
• Do not reuse drive pinion rear bearing inner race.
4. Install the collapsible spacer to the drive pinion.
CAUTION:
Do not reuse collapsible spacer.
5. Apply differential gear oil to the drive pinion rear bearing, and
install the drive pinion assembly to the gear carrier.

lower limit first. Do not exceed the drive pinion lock nut
specified torque. Refer to
.
• If the drive pinion bearing preload torque exceeds the
specified value, replace collapsible spacer and tighten it
again to adjust. Do not loosen drive pinion lock nut to
adjust the drive pinion bearing preload torque.
• After adjustment, rotate drive pinion back and forth 2 to 3
times to check for unusual noise, rotation malfunction,
and other malfunctions.
