>>H<< Final Drive Gear Backlash Adjustment

Adjust the final drive gear backlash by the following procedure:

1. Assemble the differential case with the side bearing outer race to the differential carrier.
2. Press the differential case to one side to measure the clearance of the side bearing outer race and the differential carrier.
3. Select two pairs of side bearing spacers. Determine the thickness by adding 1/2 of the clearance to the pre-load 0.05 mm (0.002 inch).
4. Assemble the selected side bearing spacers to each side.

5. Measure the final drive gear backlash at four points or more on the circumference of the drive gear.

   Standard value: 0.11 - 0.16 mm (0.004 - 0.006 inch)

6. If the backlash is not within the standard value, move the side bearing spacer as shown in the illustration to adjust the backlash.
   NOTE: The increment of side bearing spacer must be the same as the decreased amount.
7. Inspect the tooth condition at the final drive gear and replace if required. (Refer to DISASSEMBLY .)

8. Measure the drive gear runout.

   Limit: 0.05 mm (0.002 inch) 

9. If drive gear runout exceeds the limit, remove the differential case and then the drive gears, moving them to different positions and reinstall them.
10. If adjustment is not possible, replace the differential case or drive gear and drive pinion as a set.
