4053825 CUMMINS Single Cylinder, Air Compressor

The air compression process is critical for the pneumatic systems of heavy commercial vehicles, ensuring consistent pressure for braking and suspension. This single cylinder air compressor is engineered to meet the rigorous demands of heavy-duty engine environments, providing stable performance through high-strength components and precise engineering.

The 4053825 is the OE equivalent of the CUMMINS 4053825 air compressor used in CUMMINS M11, N14, and ISM engine series. This part features a Ø85.00 mm cylinder bore, a 56 mm stroke, and a swept volume of 318cm³. It is specifically designed for water-cooled (W) systems with an air inlet port of Ø25 and an air outlet port of M27x2. The 4053825 is the OE equivalent of the CUMMINS 4053825 single cylinder air compressor used in CUMMINS M11, N14, and ISM engines.

For workshop technicians, this unit includes an ESS feature and a water-cooled valve plate to ensure thermal stability. The installation requires attention to the water inlet/outlet ports (3/4" - 16 UNF) and the M10x1 air unloader port to maintain optimal system pressure. Regular inspection of the through drive and cooling connections is recommended to prevent pressure fluctuations during operation.

Selecting a high-quality replacement ensures that the vehicle's pneumatic braking capabilities remain within safety standards. This component is built to withstand high-stress cycles common in heavy commercial vehicle transport.
