ASSEMBLY INSPECTION AND ADJUSTMENT
●
Drain the differential gear oil before inspection and adjustment. Refer to
●
Remove and install the carrier cover as necessary for inspection and adjustment. Refer to
.
Total Preload Torque
1.
Remove the side flanges if necessary. Refer to
.
CAUTION:
The side flanges shaft must removed in order to measure total preload torque.
2.
Rotate the drive pinion back and forth 2 to 3 times to check for unusual noise and rotation malfunction.
3.
Rotate the drive pinion at least 20 times to check for smooth operation of the bearings.
4.
Measure total preload torque using Tool.
NOTE:
Total preload torque = Drive pinion bearing preload torque +
Side bearing preload torque
●
If the measured value is out of the specification, check and adjust each part. Adjust the drive pinion
bearing preload torque first, then adjust the side bearing preload torque.
CAUTION:
Select a side bearing adjusting washer for right and left individually.
Drive Gear Runout
1.
Fit a dial indicator to the drive gear back face.
2.
Rotate the drive gear to measure runout.
●
If the runout is outside of the limit, check the condition of the
drive gear assembly. Foreign material may be caught between
the drive gear and differential case, or the differential case or
drive gear may be deformed.
CAUTION:
Replace drive gear and drive pinion as a set.
Tool number
: ST3127S000 (J-25765-A)
Total preload torque:
2.84 - 3.75 N·m (0.29 - 0.38 kg-m, 26 - 33 in-lb)
SPD884
If the total preload torque is greater than specification
On drive pinion bearings:
Replace the collapsible spacer.
On side bearings:
Use thinner side bearing adjusting washers by the same
amount on each side. Refer to
RFD-39, "Side Bearing Adjusting
.
If the total preload torque is less than specification
On drive pinion bearings:
Tighten the drive pinion lock nut.
On side bearings:
Use thicker side bearing adjusting washers by the same
amount on each side. Refer to
Runout limit
: 0.05 mm (0.0020 in) or less

Tooth Contact
1.
Apply red lead to the drive gear.
NOTE:
Apply red lead to both faces of three to four gears, at four loca-
tions evenly spaced on the drive gear.
2.
Rotate the drive gear back and forth several times. Then check
for correct drive pinion to drive gear tooth contact as shown.
CAUTION:
Check tooth contact on drive side and reverse side.
3.
If the 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), use a thicker drive pinion height adjusting
washers to move the drive pinion closer to the drive gear.
Refer to
RFD-39, "Drive Pinion Height Adjusting Washer"
