3948846 CUMMINS ISC Single Cylinder, Air Compressor

The 3948846 single cylinder air compressor is a critical component engineered to provide consistent air pressure for heavy commercial vehicle pneumatic systems. This water-cooled unit is designed with high-strength components to withstand rigorous operational demands, ensuring the reliability of the engine's air supply system.

This part serves as the OE-equivalent for the CUMMINS 3948846 single cylinder air compressor used in CUMMINS ISC engines. It features a precision-engineered Ø85.00 cylinder bore and a 56 mm stroke, delivering a swept volume of 318cm³. The unit includes an M27x2 air outlet port and an M10x1 air unloader port to meet exact technical specifications for seamless integration.

For workshop technicians, this component offers high assembly ease with its specific water inlet and outlet ports (3/4" - 16 UNF). Maintenance and installation should be performed following standard industrial protocols for water-cooled air compressors to ensure optimal thermal regulation. The presence of the ESS feature and water-cooled valve plate ensures long-term stability under heavy-duty service conditions.

Maintaining the integrity of the air compression cycle is vital for vehicle safety and performance. This single cylinder model is specifically engineered for the CUMMINS ISC series to prevent pressure drops and ensure the pneumatic braking or auxiliary systems function within prescribed parameters.
