ASSEMBLY INSPECTION AND ADJUSTMENT

Before inspection and adjustment, drain gear oil.
Total Preload Torque
1. Secure final drive assembly onto an attachment.
2. Remove side flanges.
3. Rotate drive pinion back and forth 2 to 3 times to check for unusual noise and rotation malfunction.
4. Rotate drive pinion at least 20 times to check for smooth opera-
tion of the bearing.
5. Measure total preload with the preload gauge.
NOTE:
Total preload torque = Pinion bearing preload torque + Side
bearing preload torque

If measured value is out of the specification, disassemble it to
check and adjust each part. Adjust the pinion bearing preload and side bearing preload.
Adjust the pinion bearing preload first, then adjust the side bearing preload.
Drive Gear Runout
1. Remove rear cover. Refer to RFD-22, "Differential Assembly" .
2. Fit a dial indicator to the drive gear back face.
3. Rotate the drive gear to measure runout.

If the runout is outside of the repair limit, check drive gear
assembly condition; foreign material may be caught between
drive gear and differential case, or differential case or drive gear
may be deformed, etc.
CAUTION:
Replace drive gear and drive pinion gear as a set.Tool number A: KV38100800 (J-25604-01)
Tool number A: ST3127S000 (J-25765-A)
Total preload torque:
2.84 - 3.75 N·m (0.29 - 0.38 kg-m, 26 - 33 in-lb)
PDIA0766J
When the preload torque is large
On pinion bearings: Replace the collapsible spacer.
On side bearings: Use thinner side bearing adjusting washers by the same amount to
each side. Refer to RFD-38, "
Side Bearing Adjusting Washer" .
When the preload is small
On pinion bearings: Tighten the drive pinion lock nut.
On side bearings: Use thicker side bearing adjusting washers by the same amount to
each side. Refer to RFD-38, "
Side Bearing Adjusting Washer" .
Runout limit: 0.05 mm (0.0020 in)

4. Install bearing caps in their correct locations and tighten bearing
cap mounting bolts to the specified torque. Refer to RFD-18,
"COMPONENTS" .
5. Turn the carrier several times to seat the bearings.
6. Measure the turning torque of the carrier at the drive gear
mounting bolts with a spring gauge.
7. If the turning torque is outside the specification, use a thicker/
thinner side bearing adjusting washer to adjust. Refer to RFD-
38, "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.
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-18,
"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.
