1W8922 Piston Ring Group — Cat 16G 245

This is a piston ring group, a critical set of rings that seal the combustion chamber and control oil consumption within the engine cylinder. Manufactured to precise tolerances, these rings offer superior wear resistance and sealing capabilities compared to worn or broken rings. Operators may observe increased oil consumption, blue smoke from the exhaust, or a loss of engine compression and power when this component fails.

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 initial symptom of worn piston rings is often increased blue or grey smoke from the exhaust, especially during acceleration. As the rings degrade further, oil consumption will rise significantly, and engine compression will decrease, leading to noticeable power loss. Continued operation can result in oil fouling of spark plugs and potential cylinder wall damage.

Installation Tip

Ensure the cylinder walls are clean and free of any burrs or scratches before attempting to install the rings. Stagger the ring gaps according to the manufacturer's specifications to ensure proper sealing.

Service Note

Inspect cylinder liners for wear and hone if necessary; check piston condition and skirt clearance.
