Confirm correct model: Use SINOTRUK EPC system to verify compatibility with your VIN/chassis.
Inspect new cover: Check for cracks, damaged threads, warped sealing surface, or broken ribs.
Clean mating surfaces: Remove old gasket material, oil residue, rust, and debris from both the axle housing and cover flange.
Prepare seal: Use new paper gasket or apply liquid sealant (e.g., ThreeBond 1215) per manufacturer instructions.
Position the Cover:
Align carefully with axle housing opening.
Ensure no binding or misalignment.
Apply Sealant or Install Gasket:
Place new paper gasket or apply thin bead of liquid sealant.
Avoid excess that could enter the oil chamber.
Insert Fasteners:
Start all M12 bolts finger-tight.
Use crisscross diagonal sequence.
Torque Properly:
Final torque: 85–110 N·m (confirm exact value per service manual).
Apply gradually in stages to prevent warping.
Check Vent Plug:
Ensure breather valve is clean and unobstructed.
Final Inspection:
Visually inspect joint line for even contact.
Refill with proper gear oil after installation.
