REAR FINAL DRIVE ASSEMBLY
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
