Rotate drive pinion back and forth 2 to 3 times to check for unusual noise and rotation malfunction. 3. Rotate drive pinion at least 20 times to check for smooth opera- 4. Fit drive pinion socket onto drive pinion spline. Measure the total NOTE: • 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. DRIVE GEAR RUNOUT 1. Remove rear cover. Refer to . 2. Following the procedure below, install a dummy cover set (SST: KV389L0010) to gear carrier. a. Set dummy cover shims to the right and left side bearing adjusting shims. b. Temporarily tighten dummy cover to gear carrier. c. Position dummy cover spacers to dummy cover. d. Tighten rear cover mounting bolts to the specified torque. Refer to . e. Tighten dummy cover spacer mounting bolts evenly to the specified torque. 3. Fit a dial indicator to the drive gear back face. 4. 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 CAUTION: Replace drive gear and drive pinion as a set. Standard Total preload torque : Refer to 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.
