2171573 Kit-Piston Rings — Cat 550B 560B

This kit contains piston rings essential for sealing the combustion chamber, controlling oil consumption, and transferring heat from the piston to the cylinder wall. Manufactured to precise tolerances, these rings offer superior sealing and wear resistance compared to worn or broken rings. Operators may notice increased oil consumption, blue smoke from the exhaust, or a loss of engine power when these rings begin 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

The first symptom of worn piston rings is typically an increase in oil consumption and blue smoke from the exhaust. If left unaddressed, blow-by will increase, leading to a loss of compression and noticeable power reduction. Continued operation can lead to cylinder wall scoring and potential engine seizure.

Installation Tip

Carefully inspect the cylinder walls for any scoring or damage before installing the new rings; hone the cylinders if necessary according to specifications. Ensure the ring gaps are staggered correctly around the piston to maintain proper sealing.

Service Note

Inspect cylinder liners for wear and measure piston-to-liner clearance when replacing piston rings.
