3767362 Body As-Piston — Cat 773F 773G lRC

This Body As-Piston is a core component within the engine's cylinder assembly, housing the piston and facilitating combustion. Manufactured to meet rigorous CTP aftermarket replacement standards, it offers durability comparable to OEM parts, unlike a worn or scored cylinder bore that can lead to blow-by and reduced compression. Operators may observe increased oil consumption, blue exhaust smoke, and a noticeable loss of engine power when this component is compromised.

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 Body As-Piston include increased oil consumption and blue smoke from the exhaust. If ignored, this can lead to a significant loss of engine power and potential over-heating due to blow-by. Continued operation risks scoring of the piston and cylinder wall, leading to premature engine wear and potential seizure.

Installation Tip

Thoroughly clean the cylinder block deck and ensure the cylinder bore is honed to the correct surface finish before installing the piston and connecting rod assembly. Avoid dropping the piston into the bore without a proper ring compressor, as this can damage the piston rings.

Service Note

When replacing a Body As-Piston, it is essential to inspect and replace the piston rings, connecting rod bearings, and cylinder liners if applicable.
