Failure Symptoms

Initial symptoms of a failing piston include a noticeable reduction in engine power and increased exhaust emissions. If left unaddressed, the engine may begin to consume excessive oil, leading to potential lubrication issues and further internal damage. The primary risk is severe engine damage, resulting in costly repairs and extended equipment downtime.

Installation Tip

Ensure the cylinder bore is perfectly clean and lubricated with assembly lube before installing the piston to prevent scoring. Never reuse old piston rings; always install new ones with the piston.

Service Note

Replace piston rings, connecting rod bearings, and inspect cylinder liners when installing this piston.
