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 drop in engine horsepower and an increase in exhaust smoke. If left unaddressed, the engine may begin to consume excessive oil, leading to fouled spark plugs and further internal damage. Continued operation risks severe cylinder wall scoring and potential engine seizure.

Installation Tip

Ensure the cylinder bore is meticulously cleaned and free of any debris before installing the new piston. Avoid forcing the piston into the cylinder bore; proper ring compression and lubrication are essential to prevent damage.

Service Note

Always inspect cylinder liners, connecting rod bearings, and piston rings for wear when replacing a piston.
