3103403 CUMMINS Single Cylinder, Air Compressor

This single cylinder air compressor serves as a vital component within the pneumatic system of heavy-duty engines, ensuring consistent air pressure for braking operations. Designed with a robust structure, it features a water-cooled design to maintain optimal operating temperatures under demanding conditions.

The 3103403 is the OE equivalent of the CUMMINS 3103403 air compressor used in CUMMINS M11, N14, ISM, and QSM11 engines. This high-strength component features an 85.00 mm bore and a 56 mm stroke to provide reliable performance within the engine's air brake system.

Technicians can rely on its precise specifications, including an M27x2 air outlet port and M10x1 unloader port. The unit is designed for easy integration into existing engine architectures, featuring a through-drive design and specialized water inlet/outlet ports for efficient thermal management.

Regular inspection of the water cooling ports and ensuring the integrity of the M27x2 outlet is recommended during routine maintenance to prevent system downtime in heavy commercial vehicles.
