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-24, "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 : KV38100800 (J-25604-01)
Tool number : ST3127S000 (J-25765-A)
Total preload torque:
2.85 – 3.75 N·m (0.29 – 0.38 kg-m, 26 – 33 in-lb)
PDIA0635E
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-60, "
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-60, "
Side Bearing Adjusting Washer" .
Runout limit: 0.05 mm (0.0020 in) or less

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.

CAUTION:
Do not reuse drive pinion lock nut.
11. Adjust to the drive pinion lock nut tightening torque and pinion
bearing preload torque.
CAUTION:

Adjust to the lower limit of the drive pinion lock nut tight-
ening torque first.

If the 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 preload torque.

After adjustment, rotate drive pinion back and forth 2 to 3 times to check for unusual noise, rota-
tion malfunction, and other malfunctions.
