Total Preload

REAR FINAL DRIVE ASSEMBLY:

TOTAL PRELOAD
1. Drain the oil.
2. Remove electric controlled coupling assembly.
3. Rotate the drive pinion back and forth in 2 to 3 times to check for unusual noise and rotation malfunction.





4. Rotate the drive pinion at least 20 times to check for smooth operation of the bearing.
5. Fit the drive pinion socket onto the drive pinion spline. Using a preload gauge, measure the total preload.

Tool number:....................A: ST3127S000 (325765-A)
Tool number:....................B: KV38108500 (-)

Total preload:....................1.33 - 2.15 Nm (0.14 - 0.21 kgf-cm, 12 - 19 inch lbs.)

If outside the standard, disassemble, check, and adjust each part. Adjust the pinion bearing and side bearing preload.
Adjust the pinion bearing preload first, then adjust the side bearing preload.

Side bearing preload:..................0.64 - 0.98 Nm (0.065 - 0.010 kgf-cm, 6 - 8 inch lbs.)



When the preload torque is large
On pinion bearings:....Replace the collapsible spacer.
On side bearings:....Use thinner side bearing adjusting shims.

When the preload is small
On pinion bearings:....Tighten the pinion nut.
On side bearings:.....Use thicker side bearing adjusting shims.
