2500 040 006 CUMMINS Single Cylinder, Air Compressor

This single-cylinder air compressor is engineered to provide consistent pneumatic pressure for heavy commercial vehicle braking systems. Designed with a Ø85.00 cylinder bore and a 56 mm stroke, the unit utilizes high-strength components to ensure long-term operational stability under heavy-duty workloads. The water-cooling system and integrated ESS feature make it an ideal choice for maintaining optimal thermal management within the engine compartment.

2500 040 006 is the OE-equivalent of the CUMMINS 4934957 and WABCO 911 153 552 0 single cylinder air compressor used in CUMMINS and WABCO heavy-duty systems. This component ensures seamless integration with existing pneumatic hardware, maintaining the strict performance standards required by professional workshop technicians and fleet managers.

The installation process requires attention to the specific port dimensions, including the 3/4”-14 NPT air inlet and outlet, as well as the water inlet and outlet ports. For optimal service life, technicians should verify the integrity of all connections and ensure the water-cooling circuit is free from obstructions. Regular maintenance of the air unloader port (M10x1) and checking for any pressure drops in the pneumatic circuit is essential for maintaining system efficiency.
