3949098 CUMMINS ISLE Single Cylinder, Air Compressor

This single cylinder air compressor is a critical component designed to maintain consistent pneumatic pressure within heavy commercial vehicle systems. Engineered for durability, it utilizes high-strength components to ensure reliable operation under demanding service conditions. The unit is specifically designed to handle the rigorous requirements of professional workshop environments and long-haul transport.

3949098 is the OE-equivalent of the CUMMINS 3949098 single cylinder air compressor used in CUMMINS ISL and ISLE engine systems. This precision-engineered part ensures seamless integration and maintains the original performance standards required by heavy-duty vehicle manufacturers. It is a direct replacement for maintaining optimal system pressure in professional fleets.

The installation process requires attention to the water cooling ports, which feature 3/4" - 16 UNF threading for both inlet and outlet. Technicians should ensure the water-cooled valve plate and ESS feature are properly integrated during assembly to prevent overheating. Proper alignment of the M27x2 air outlet and M10x1 unloader port is essential for maintaining the integrity of the pneumatic circuit.

For workshop technicians, this unit offers a robust solution for air brake system maintenance. The design features a single cylinder with a 318cm³ swept volume, providing the necessary displacement for high-demand air compression tasks. Regular inspections of the water inlet and outlet ports are recommended to ensure continuous cooling efficiency during heavy-duty operation.
