7000 922 100 Piston and Ring Kit for Air Brake Compressors

What does a compressor piston and ring do?

This compressor piston and ring set is engineered to restore the compression efficiency of pneumatic brake systems. These high-strength components are designed to withstand the intense thermal and mechanical stresses found in heavy commercial vehicle air brake compressors.

Vehicle and engine compatibility

The assembly is compatible with several heavy commercial vehicle makes including Freightliner, Kenworth, International, Peterbilt, Western Star, and Volvo. It is specifically designed for use with Cummins N14 and ISM engines. This part is also fitted to Ford Trucks, Sterling, New Flyer, Orion Bus, Gillig, and Nabi models.

Installation and maintenance guidance

When performing an overhaul, it is vital to verify the piston diameter and groove clearances against the current service manual. For optimal performance, ensure that the cylinder liner is inspected for scoring before installing these new components to prevent premature wear.

Selection for system reliability

Selecting the correct piston diameter is critical for maintaining system pressure. This unit is compatible with Holset systems and Cummins N14/ISM engine configurations to ensure reliable air delivery throughout the braking cycle.
