5301100 CUMMINS QSL9 Single Cylinder, Air Compressor

The single cylinder air compressor provides essential pneumatic pressure for heavy commercial vehicle systems, ensuring the reliable operation of braking and auxiliary pneumatic components. This unit is engineered with a robust structure to withstand the demanding thermal and mechanical stresses found in heavy-duty engine environments. Its specialized design ensures consistent air delivery through high-strength components.

5301100 is the OE equivalent of the CUMMINS 5301100 single cylinder air compressor used in the CUMMINS QSL and QSL9 engine series. This part maintains strict compatibility with original equipment specifications to ensure precise fitment within the engine compartment. By adhering to exact technical tolerances, it provides a reliable alternative for maintaining vehicle uptime.

Technical specifications include a cylinder bore of Ø85.00, a 56 mm stroke, and a swept volume of 318cm³. The unit features an air inlet port of Ø25 and an air outlet port of M27x2, along with an M10x1 air unloader port. Designed as a water-cooled (W) system, it utilizes 3/4" - 16 UNF ports for both water inlet and outlet to maintain optimal operating temperatures during long-haul transport operations.

For workshop technicians, this component offers ease of assembly due to its standard port sizes and through-drive configuration. Regular maintenance of the cooling lines and checking the water inlet/outlet connections is recommended to ensure the longevity of the compressor within the engine system.
