2500 040 005 CUMMINS Single Cylinder, Air Compressor

This single cylinder air compressor is engineered to provide consistent pneumatic pressure within heavy commercial vehicle air brake systems. Designed with a technical bore diameter of Ø85.00 and a stroke of 56 mm, the unit delivers a swept volume of 318cm³ to ensure optimal air-making capabilities. The water-cooled design, featuring specialized inlet and outlet ports, facilitates efficient thermal management during high-load operations.

2500 040 005 is the OE-equivalent single cylinder, air compressor used in CUMMINS and WABCO systems. This part is fully compatible with the CUMMINS 3357113 and WABCO 911 155 511 0 specifications. The precision-engineered components are designed to meet the rigorous demands of heavy-duty transport environments, ensuring seamless integration into existing engine architectures.

For workshop technicians performing maintenance or engine overhauls, this component features a through-drive design and standard M10x1 air unloader port for reliable assembly. The air inlet and outlet ports utilize a 3/4”-14 NPT configuration to maintain structural integrity under pressure. Regular inspection of the water cooling ports and connections is recommended to maintain peak efficiency and prevent system downtime during service intervals.
