Total Preload Torque
- Remove electric controlled coupling assembly. Refer to "DISASSEMBLY ".
- Rotate drive pinion back and forth 2 to 3 times to check for unusual noise and rotation malfunction.
- Rotate drive pinion at least 20 times to check for smooth operation of the bearing.
- Fit drive pinion socket onto drive pinion spline. Measure the total preload, using the preload gauge (A) [SST: 3127S000 (J-27565- A)] and drive pinion socket (B) [SST: KV38108500 -)].
Standard
Total preload torque : Refer to "PRELOAD TORQUE ".
NOTE:
Total preload torque = Pinion bearing torque + Side bearing 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.
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 drive pinion nut.
On side bearings: Use thicker side bearing adjusting shims.
