1850111 Kit-Piston Rings — Cat 416D 424D

This is a kit of piston rings designed to seal the combustion chamber and control oil consumption within Caterpillar engines. Manufactured to high-quality standards, these rings offer superior wear resistance and sealing compared to worn or broken rings. Operators may notice a loss of engine power, increased oil consumption, or blue smoke from the exhaust when piston rings 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

Failure of piston rings typically results in a noticeable reduction in engine power and increased oil consumption. If left unaddressed, this can lead to excessive blue smoke from the exhaust and potential cylinder wall scoring. Continued operation risks severe engine damage due to poor lubrication and combustion sealing.

Installation Tip

Carefully inspect the cylinder walls for any scoring or imperfections before installing new rings. Ensure the rings are installed in the correct orientation and order as specified by the service manual.

Service Note

Always inspect cylinder liners for wear and check piston condition when replacing piston rings.
