2500 040 004 CUMMINS Single Cylinder, Air Compressor

This single cylinder air compressor serves as a critical component within the pneumatic braking system of heavy commercial vehicles. Designed to provide consistent air pressure through a precision-engineered single cylinder, it features a water-cooling mechanism to manage thermal loads during operation. The robust construction ensures reliable performance in demanding environments, maintaining structural integrity under high-pressure cycles.

2500 040 004 is the OE-equivalent of the CUMMINS 4930344 and WABCO 911 155 062 0 single cylinder air compressor used in heavy-duty transport systems. This technical component is engineered to meet exact specifications for seamless integration with CUMMINS and WABCO hardware, ensuring optimal system synchronization and pneumatic stability.

The assembly features a single cylinder with a bore of Ø85.00 mm and a stroke of 56 mm, resulting in a swept volume of 318cm³. It includes specialized ports for both air (3/4”-14 NPT) and water (1/2”-14 NPT) to facilitate efficient cooling and pressure regulation. Workshop technicians should verify all port alignments and seal integrity during installation to ensure optimal service life.

Maintaining proper cooling flow through the water inlet and outlet ports is essential for preventing overheating during extended operation. Regular inspection of the unloader port and the through-drive mechanism is recommended to prevent pressure fluctuations within the pneumatic circuit.
