Confirm correct model: Verify WG9112540174 matches your truck’s configuration via SINOTRUK EPC system.
Inspect new bracket: Check for deformation, cracked welds, or damaged threads.
Prepare mounting area: Clean frame rail surface; remove rust, oil, or old sealant.
Gather hardware: Use original-grade bolts, washers, and lock nuts (typically M12–M14).
Position the Bracket:
Align with pre-drilled holes on the chassis side rail.
Ensure clearance from brake lines, fuel pipes, and wiring harnesses.
Insert Fasteners:
Insert high-strength bolts through both bracket and frame.
Add flat and spring washers if specified.
Torque Properly:
Tighten diagonally in stages.
Final torque: 80–100 N·m (confirm exact value in service manual).
Install Muffler Onto Bracket:
Lower muffler into place using hoist or support tool.
Secure with clamp (WG9112540018) and rubber pads (if equipped).
Final Inspection:
Visually check alignment and stability.
Shake muffler gently — no excessive movement should occur.
