5. Turn the assembly several times to seat the drive pinion bear-

ings.

6. Measure the turning torque at the end of the J-34309-2 gauge

anvil using Tool.

7. Place the J-34309-11 “R200A” 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

DLN-425,

"Exploded View"

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-34309-11 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-444, "Inspection and Adjustment"

13. Remove the Tool from the gear carrier and disassemble to

retrieve the drive pinion bearings.

7. Press the drive pinion front bearing inner race to the drive pinion

as far as drive pinion lock nut can be tightened using suitable

spacer.

8. Apply multi-purpose grease to the lips and differential gear oil to

the circumference of the new front oil seal. Then drive the new

front oil seal in evenly until it becomes flush with the gear carrier

using Tool.

CAUTION:

• Do not reuse front oil seal.

• Do not incline the new front oil seal when installing.

• Apply multi-purpose grease to the lips and differential

gear oil to the circumference of the new front oil seal.

9. Install the companion flange to the drive pinion while aligning the matching marks.
10. Apply anti-corrosive oil to the threads of the drive pinion and the

seating surface of the new drive pinion lock nut. Then adjust the

drive pinion lock nut tightening torque using suitable tool A, and

check the drive pinion bearing preload torque using Tool B.

CAUTION:

• Do not reuse drive pinion lock nut.

• Apply anti-corrosive oil to the threads of the drive pinion

and the seating surface of the new drive pinion lock nut.

• Adjust the drive pinion lock nut tightening torque to the

lower limit first. Do not exceed the drive pinion lock nut

specified torque. Refer to

DLN-425, "Exploded View"

• 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.

11. Check companion flange runout. Refer to

DLN-444, "Inspection and Adjustment"
