To guarantee the longevity of your Sinotruk howo parts and avoid premature gear failure, follow these professional guidelines:

1. Matched Set Replacement: Always replace the crown wheel and the pinion together as a matched pair (AZ9970320263). Never mix a new gear with a used one.

2. Backlash Adjustment: Use a dial indicator to set the gear backlash precisely between 0.20mm and 0.35mm (refer to the Sinotruk axle service manual).

3. Contact Pattern Test: Apply gear marking compound to check the tooth contact pattern. The contact area must be centered on the tooth flank to ensure quiet operation and even load distribution.

4. Bearing Check: Inspect and preferably replace the pinion bearings and differential bearings during the gear set installation.

5. Oil Grade: Refill the axle housing with genuine API GL-5 85W-90 heavy-duty gear oil. Ensure the housing is free of metal debris before assembly.
