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 assembly may include a noticeable decrease in engine power and increased exhaust smoke. Continued operation can lead to excessive oil consumption as the piston rings lose their seal. Ultimately, severe piston damage can result in a loss of compression and potential engine seizure.

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

When replacing a piston assembly, it is recommended to inspect the cylinder liner, connecting rod bearings, and piston rings for wear.
