4059825 CUMMINS Single Cylinder, Air Compressor

This single cylinder air compressor is engineered to provide consistent pneumatic pressure for heavy commercial vehicle systems. Designed with a robust structure, it features a cylinder bore of Ø85.00 mm and a stroke of 56 mm to ensure optimal swept volume and performance during operation.

The 4059825 is the OE equivalent of the CUMMINS 4059825 air compressor used in CUMMINS M11, N14, ISM, and QSM11 engine configurations. This high-strength component is designed for water-cooled systems, featuring specific inlet and outlet ports to maintain thermal stability under heavy loads.

For the workshop technician, this part offers a precise fit with an M27x2 air outlet port and an M10x1 unloader port. The unit is specifically designed to integrate with existing water-cooled engine architectures to manage heat dissipation effectively during high-pressure cycles.

Regular maintenance of the air delivery system is essential to prevent downtime in fleet operations. Technicians should monitor the water inlet and outlet connections to ensure the cooling function remains optimal for the longevity of the compressor.
