1723280 Body As-Piston — Cat 24H 631e

This is a precision-machined piston body that forms the upper seal of the combustion chamber, driven by combustion pressure and connected to the crankshaft via the connecting rod. Constructed from high-grade aluminum alloy, it offers excellent heat dissipation and durability compared to a worn piston with scoring or a damaged crown. Operators may notice increased oil consumption, blue exhaust smoke, or a loss of engine power when this component begins to fail.

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

Early signs of a failing piston body include increased oil consumption and visible blue smoke from the exhaust due to oil entering the combustion chamber. As wear progresses, engine power will noticeably decrease, and the engine may run rough. Severe damage can lead to piston seizure or failure, causing significant internal engine damage.

Installation Tip

Ensure the cylinder bore is clean and free of any debris or scoring before installing the new piston. Always install new piston rings and ensure they are correctly oriented according to the manufacturer's instructions.

Service Note

When replacing pistons, always inspect the cylinder liners for wear, taper, and out-of-roundness, and check the connecting rod and main bearings for proper clearance.
