5286661 CUMMINS Twin Cylinder, Air Compressor

This twin cylinder air compressor is engineered to provide consistent pneumatic pressure within the engine's air braking system. Designed with a robust structure, it serves as a critical component for maintaining stable air supply in heavy-duty environments. The unit features a water-cooled design to manage thermal loads effectively during high-demand operation.

5286661 is the OE-equivalent CUMMINS air compressor used in CUMMINS systems. This high-strength component ensures seamless integration with existing engine architectures, maintaining the required pressure levels for heavy commercial vehicle safety and operational efficiency.

The technical specifications include a cylinder bore of Ø75.00 mm and a stroke of 56 mm, delivering a swept volume of 495cm³. For workshop technicians, it is essential to note the water inlet and outlet ports use 3/4-16 UNF threads, and the air outlet port is M27x2. Proper installation and verification of the water-cooled valve plate and port connections are vital for maintaining optimal service intervals.

This component is specifically designed for heavy commercial vehicle applications where reliability under constant load is required. Regular inspections of the air unloader port (M10x1) and the connection points are recommended to prevent system pressure drops.
