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

Early signs of piston issues can include a noticeable drop in engine power and increased exhaust smoke. If the problem progresses, the engine may start to run roughly, misfire, or consume excessive oil. Severe piston damage can lead to catastrophic engine failure and extensive repair costs.

Installation Tip

Ensure the cylinder bore is perfectly clean and honed to the correct specification before installing the piston. Never force a piston into the cylinder; use the appropriate ring compressor and ensure correct orientation.

Service Note

Replace the piston rings, connecting rod bearings, and inspect the cylinder liner for wear or damage when replacing a piston.
