Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

Initial signs of a failing piston may include a noticeable decrease in engine horsepower and an increase in exhaust smoke. If ignored, the piston can begin to score the cylinder wall, leading to increased oil consumption and blow-by. Continued operation risks severe cylinder and crankshaft damage.

Installation Tip

Ensure the cylinder bore is thoroughly cleaned and inspected for any imperfections before installing the new piston. Avoid forcing the piston into the cylinder bore, as this can damage the piston skirt or the cylinder wall.

Service Note

Inspect cylinder liners, piston rings, and connecting rod bearings for wear or damage when replacing the piston assembly.
