4936218 CUMMINS QSL Single Cylinder, Air Compressor

This single cylinder air compressor is engineered to provide reliable pneumatic pressure for heavy-duty engine systems. Designed with a robust architecture, it features a water-cooling system to maintain optimal operating temperatures during intensive cycles. The component is built with high-strength components to ensure long-term durability under demanding workshop environments.

4936218 is the OE equivalent of the CUMMINS 4936218 single cylinder air compressor used in the CUMMINS QSL engine series. This part ensures seamless integration with the original engine system, maintaining the precise airflow required for heavy commercial vehicle operations. It is specifically designed to meet the rigorous standards of heavy-duty engine-driven pneumatic systems.

For workshop technicians, this unit features a Ø85.00 cylinder bore and a 56 mm stroke, providing a swept volume of 318cm³. The assembly includes a Ø25 air inlet port and an M27x2 air outlet port, along with an M10x1 air unloader port. Proper installation involves verifying the water inlet/outlet connections (3/4" - 16 UNF) to ensure efficient thermal management within the engine bay.

Regular maintenance of the air intake and cooling lines is recommended to prevent performance degradation. Technicians should monitor the through-drive and ESS feature functionality during routine service intervals to ensure the compressor remains in peak working condition for the fleet.
