5257938 CUMMINS Twin Cylinder, Air Compressor

This heavy-duty twin cylinder air compressor is engineered to provide consistent pneumatic pressure for heavy commercial vehicle air brake systems. Designed with a robust construction, it ensures high-strength performance in demanding environments where reliability is critical for vehicle safety and operational uptime.

5257938 is the OE-equivalent of the CUMMINS 5257938 twin cylinder air compressor used in CUMMINS heavy commercial vehicle systems. This component is manufactured to meet strict technical standards, ensuring seamless integration and long-term functionality within the engine's cooling and pneumatic architecture.

Workshop technicians can rely on the precise dimensions of this unit, featuring an Ø86.00 mm cylinder bore and a 40 mm stroke. The assembly includes specialized water-cooled ports (M16x1,5) to manage thermal loads effectively during continuous operation. Regular inspection of the water inlet and outlet connections is recommended to maintain optimal cooling efficiency and prevent system overheating.

Installation involves securing the through-drive mechanism and ensuring the M26x1,5 air ports are properly seated to maintain pressure integrity. This part is specifically designed for heavy-duty applications requiring a 460cm³ swept volume to support high-demand braking systems in large-scale transport fleets.
