3103403 CUMMINS N14 Single Cylinder Air Compressor

This heavy-duty single cylinder air compressor is engineered to provide consistent pneumatic pressure within the vehicle's air system. Designed with a robust architecture, it features a single cylinder with an 85.00 mm bore and a 56 mm stroke, delivering a total swept volume of 318cm³. The unit is specifically optimized for water-cooled environments to maintain optimal thermal stability during operation.

3103403 is the OE-equivalent of the CUMMINS 3103403 single cylinder air compressor used in the CUMMINS N14 engine. This component is essential for maintaining the pneumatic integrity of the braking and suspension systems in heavy commercial vehicles. It features a Ø25 air inlet port and an M27x2 outlet port, ensuring compatibility with standard industrial fittings.

Workshop technicians can rely on the precision-engineered dimensions for seamless installation. The unit includes an M10x1 air unloader port and is designed for water-cooled (W) applications with 3/4" - 16 UNF inlet and outlet ports. Regular inspections of the water cooling lines and air port seals are recommended to ensure the longevity of the high-strength components in demanding service environments.
