4. If tooth contact is improperly adjusted, follow the procedure
below to adjust the pinion height (dimension X).

If the tooth contact is near the face (face contact), or near the
heel (heel contact), thicken pinion height adjusting washers to
move drive pinion closer to drive gear.
Refer to RFD-60, "
Pinion Height Adjusting Washer" .

If the tooth contact is near the flank (flank contact), or near the
toe (toe contact), thin pinion height adjusting washers to move
drive pinion farther from drive gear.
Refer to RFD-60, "
Pinion Height Adjusting Washer" .
Backlash
1. Remove rear cover. Refer to RFD-44, "Differential Assembly" .
2. Fit a dial indicator to the drive gear face to measure the back-
lash.

If the backlash is outside of the specified value, change the
thickness of side bearing adjusting washer.
CAUTION:
Do not change the total amount of washers as it will change the bearing preload.

Backlash: 0.10 – 0.15 mm (0.0039 – 0.0059 in)
When the backlash is large:
Make drive gear back side adjusting washer thicker,
and drive gear tooth side adjusting washer thinner by
the same amount. Refer to RFD-60, "
Side Bearing
Adjusting Washer" .
When the backlash is small:
Make drive gear back side adjusting washer thinner,
and drive gear tooth side adjusting washer thicker by
the same amount. Refer to RFD-60, "

3. Put matching mark on the end of drive pinion. The matching
mark should be in line with the matching mark A on companion
flange.
CAUTION:
For matching mark, use paint. Do not damage companion
flange and drive pinion.
NOTE:
The matching mark A on the final drive companion flange indi-
cates the maximum vertical runout position.
When replacing companion flange, matching mark is not neces-
sary.
4. Remove companion flange using the suitable puller.
5. Press drive pinion assembly out of gear carrier.
CAUTION:
Do not drop drive pinion assembly.
6. Remove front oil seal.
7. Remove side oil seal.
8. Remove pinion front bearing inner race.
9. Remove collapsible spacer.
10. Remove pinion rear bearing inner race and drive pinion height
adjusting washer with the replacer.
11. Tap pinion front/rear bearing outer races uniformly a brass rod or
equivalent to removed.
CAUTION:
Be careful not to damage gear carrier.

7. If the turning torque is outside the specification, use a thicker/
thinner side bearing adjusting washer to adjust. Refer to RFD-
60, "Side Bearing Adjusting Washer" .
CAUTION:
Select a side bearing adjusting washer for right and left
individually.
8. Record the total amount of washer thickness required for the correct carrier side bearing preload.
Pinion Gear Height
1. Make sure all parts are clean and that the bearings are well
lubricated.
2. Assemble the pinion gear bearings into the differential shim
selector tool.

Pinion front bearing; make sure the J-34309-3 pinion front
bearing seat is secured tightly against the J-34309-2 gauge
anvil. Then turn the pinion front bearing pilot, J-34309-5, to
secure the bearing in its proper position.

Pinion rear bearing; the pinion rear bearing pilot, J-34309-8,
is used to center the pinion rear bearing only. The pinion rear
bearing locking seat, J-34309-4, is used to lock the 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 pinion rear bearing inner race into gear carrier. Then
place the pinion preload shim selector tool, J-34309-1, gauge
screw assembly.If the turning torque is less than the specified range:
Use a thicker thrust washer.
If the turning torque is greater than the specification:
Use a thinner thrust washer.

4. Assemble the pinion front bearing inner race and the J-34309-2
gauge anvil. Assemble them together with the J-34309-1 gauge
screw in gear carrier. Make sure that the pinion height gauge
plate, J-34309-16, will turn a full 360 degrees. Tighten the two
sections together by hand.
5. Turn the assembly several times to seat the bearings.
6. Measure the turning torque at the end of the J-34309-2 gauge
anvil using preload gauge.
7. Place the J-34309-11 “R200A” 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, J-25269-4, and arbor firmly into
the side bearing bores. Install the bearing caps and tighten bear-
ing cap mounting bolts to the specified torque. Refer to RFD-39,
"COMPONENTS" .

9. Select the correct standard pinion height adjusting washer thick-
ness. 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 pinion height adapter including the standard
gauge and the arbor.
10. Write down exact measurement (the value of feeler gauge).
11. Correct the pinion height washer size by referring to the “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 “pinion head height
number”. It refers to the ideal pinion height from standard
for quietest operation. Use the following chart to determine
the correct pinion height washer.
12. Select the correct pinion height adjusting washer. Refer to RFD-60, "
Pinion Height Adjusting Washer" .
