3558163 Compressor ISM Compatible

What does a single cylinder compressor do?

This single cylinder air brake compressor serves as a vital component in the pneumatic system of heavy commercial vehicles. By utilizing a piston-type mechanism, it generates the necessary compressed air required for the braking system and air processing units. This specific model is designed with high-strength components to withstand the rigorous thermal and pressure demands of continuous operation.

Engine compatibility and fitment

This unit is specifically compatible with Cummins ISM, M11, N14, and QSM11 engines. It functions effectively within the engine's cooling circuit via its water-cooled design, ensuring stable performance under heavy loads. The assembly includes a water-cooled valve plate and an integrated ESS feature to maintain optimal air delivery cycles.

Installation and maintenance guidance

For proper installation and maintenance, technicians should verify the water inlet and outlet connections (3/4" - 16 UNF) and ensure the air outlet port (M27x2) is securely seated. Regular inspection of the through-drive mechanism and unloader port (M10x1) is recommended to prevent system pressure fluctuations and ensure long-term reliability in service.

Troubleshooting and service tips

Monitoring the air inlet (Ø25) and checking for leaks in the cooling lines can prevent premature wear of internal components. Maintaining clean coolant flow is essential for this water-cooled assembly to prevent overheating during long-haul operations.
