2500 040 005 CUMMINS Single Cylinder, Air Compressor

This single cylinder air compressor is a critical component designed to provide consistent pneumatic pressure within the braking system. Engineered with high-strength components, it ensures reliable operation under heavy-duty service conditions, maintaining the necessary air supply for heavy commercial vehicle safety systems.

The 2500 040 005 is the OE equivalent of the CUMMINS 3357113 and WABCO 9111555110 used in CUMMINS and WABCO systems. It features a cylinder bore of Ø85.00 and a swept volume of 318cm³, making it a precise match for compatible engine setups. This component is specifically designed for water-cooled applications to manage thermal loads effectively during operation.

Technical specifications include a through-drive capability and an air unloader port of M10x1. The air inlet and outlet ports are sized at 3/4”-14 NPT to ensure standardized connectivity. When performing maintenance or replacement, technicians should verify the water inlet and outlet port compatibility, which are sized at 1/2”-14 NPT, to ensure seamless integration with the existing cooling circuit.

Proper installation of this compressor is essential for maintaining optimal air brake performance. Technicians should inspect the through-drive mechanism and the ESS feature functionality during routine service intervals to prevent system downtime.
