ASSEMBLY
1. DIFFERENTIAL CASE ASSEMBLY
1. Install bevel gear and bevel pinion together with washers, and insert pinion shaft.
NOTE: Face the chamfered side of washer toward gear.
2. Measure backlash between bevel gear and pinion. If it is not within specifications, install a suitable washer to adjust it.
NOTE: Be sure the pinion gear tooth contacts adjacent gear teeth during measurement.
