3949718 CUMMINS Single Cylinder, Air Compressor

This high-strength single cylinder air compressor is engineered to provide reliable pneumatic pressure within the engine system. Designed for heavy commercial vehicle applications, it ensures consistent performance through its robust construction and optimized swept volume of 318cm³.

The 3949718 model serves as the OE equivalent of the CUMMINS 3949718 air compressor used in professional heavy-duty systems. This component features a Ø85.00 cylinder bore and a 56 mm stroke, ensuring precise operation. The technical specifications include an air inlet port of Ø25 and a water-cooling system with 3/4" - 16 UNF ports to maintain optimal operating temperatures.

For workshop technicians, this part offers a direct fit with an ESS feature and a through-drive configuration. Maintenance should focus on the integrity of the water inlet and outlet ports to prevent overheating during high-load cycles. Always verify the compatibility of the M10x1 air unloader port with existing pneumatic lines.

Regular inspection of the water-cooled components and ensuring the path for the 56 mm stroke remains unobstructed will extend the service life of the compressor in demanding environments.
