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 body assembly may include a noticeable decrease in engine horsepower and increased fuel consumption. If left unaddressed, the issue can lead to excessive oil consumption and rough engine operation. Continued operation with a compromised piston body assembly risks severe internal engine damage.

Installation Tip

Ensure the cylinder bore is thoroughly cleaned and inspected for any scoring before installing the new piston body. Avoid dropping or striking the piston body during installation to prevent damage to its critical surfaces.

Service Note

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