2500 030 003 Single Cylinder Compressor for Cummins Engines

What does a single cylinder compressor do?

This single cylinder air brake compressor is a piston-type component designed to generate the compressed air required for the operation of braking systems in heavy commercial vehicles. By utilizing a high-strength component construction, it ensures consistent pressure delivery even under demanding service conditions. The unit is integrated into the engine drive to facilitate efficient air production.

Compatible vehicles and engines

This component is extensively used in heavy commercial vehicles including International, Kenworth, Peterbilt, and Freightliner trucks. It is specifically engineered to work with Cummins ISM, N14, and X15 engines across various models such as the International Workstar and Kenworth T800. The design ensures seamless integration within the pneumatic architecture of these heavy-duty platforms.

Installation and maintenance

Installation requires careful attention to the water cooling ports and air outlet connections. This specific model features a 3/4 - 16 UNF water inlet and outlet port configuration and an M27x2 air outlet port. Technicians should verify the through drive alignment and ensure the water-cooled valve plate is properly seated during assembly to maintain optimal performance.

Troubleshooting and inspection

Regular inspection of the air inlet port and unloader valve is recommended to prevent system pressure fluctuations. Maintaining clean cooling lines for the water-cooled design helps prevent overheating during sustained heavy-load operations.
