1850110 Kit-Piston Rings — Cat 416D 424D

This piston ring kit is a set of precisely engineered rings that seal the combustion chamber, control oil consumption, and transfer heat from the piston to the cylinder wall. Manufactured to meet CTP aftermarket standards, these rings provide optimal sealing and wear resistance compared to worn or broken rings that lead to blow-by and oil burning. Operators may notice a loss of engine power, increased oil consumption, blue smoke from the exhaust, and reduced compression when these rings are failing.

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

A significant increase in oil consumption and visible blue smoke from the exhaust are common initial symptoms of worn piston rings. This can progress to a noticeable loss of engine power and reduced acceleration due to poor cylinder sealing and blow-by. Continued operation with faulty rings can lead to increased fuel consumption, potential cylinder wall damage, and eventual engine failure.

Installation Tip

Ensure the cylinder walls are clean and free of any scoring or debris before installing the new rings to prevent immediate damage. Stagger the ring gaps according to the manufacturer's specifications to ensure proper sealing.

Service Note

Inspect cylinder liners, pistons, connecting rods, and engine bearings for wear or damage when replacing the piston ring kit.
