3680441 CUMMINS N14 Single Cylinder Air Compressor

The single cylinder air compressor serves as a critical component in the pneumatic system of heavy commercial vehicles, providing the necessary compressed air for brake and suspension operations. This specific model is engineered with high-strength components to ensure durability under demanding thermal and mechanical stresses during long-haul transport.

3680441 is the OE-equivalent CUMMINS Single Cylinder Air Compressor used in the CUMMINS N14 engine. This unit features a Ø85.00 mm cylinder bore, a 56 mm stroke, and a swept volume of 318cm³. It is specifically designed to be compatible with CUMMINS (3680441) systems, ensuring seamless integration with heavy-duty engine architectures.

For workshop technicians, this water-cooled compressor includes an air inlet port of Ø25 and an air outlet port of M27x2. The installation requires attention to the water inlet and outlet ports (3/4" - 16 UNF) to ensure proper cooling efficiency. Regular maintenance of the water-cooled valve plate and checking the M10x1 air unloader port are essential for sustained reliability during service intervals.

Maintaining precise air pressure through this single-cylinder unit is vital for the safety and performance of the vehicle's braking system. Given its high-performance specifications, including the ESS feature and through-drive capability, it meets the rigorous standards required for heavy commercial vehicle fleet management.
