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 piston failure may include a noticeable drop in engine performance and increased exhaust smoke. If ignored, the problem can escalate to excessive oil burning and potential engine misfires. Continued operation with a failing piston risks severe internal engine damage.

Installation Tip

Ensure the cylinder bore is thoroughly cleaned and free of any debris before installing the new piston. Avoid forcing the piston into the cylinder bore, as this can cause damage to the piston skirt or the cylinder wall.

Service Note

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