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

A failing piston body assembly may initially present as a noticeable decrease in engine power and responsiveness. If ignored, this can lead to uneven engine operation, increased fuel consumption, and potential damage to other engine components. Continued operation with a compromised assembly risks severe internal engine damage.

Installation Tip

Ensure the cylinder bore is meticulously clean and free of any debris before installing the new piston assembly. Avoid forcing the assembly into the bore, as this can damage the piston skirts or cylinder walls.

Service Note

Inspect the cylinder liner and piston rings for wear or scoring when replacing the piston body assembly.
