4933782 CUMMINS QSL Single Cylinder, Air Compressor

The single cylinder air compressor is a critical component in the pneumatic systems of heavy commercial vehicles, providing the necessary compressed air for operational stability. This unit is designed with high-strength components to withstand rigorous duty cycles within the engine compartment. By maintaining consistent pressure levels, it ensures the reliable functioning of various braking and pneumatic subsystems.

4933782 is the OE-equivalent of the CUMMINS 4933782 single cylinder air compressor used in CUMMINS QSL engines. This unit is engineered to meet strict technical requirements, featuring a Ø85.00 cylinder bore and a 56 mm stroke. Its water-cooled design and specific port dimensions, including a 3/4" - 16 UNF water inlet and outlet, facilitate optimal thermal management during operation.

Workshop technicians should ensure precise alignment during installation to maintain the integrity of the through-drive system. The component features an M27x2 air outlet port and an M10x1 unloader port for seamless integration with existing pneumatic lines. Regular inspections of the water cooling connections and air ports are recommended to prevent leaks or pressure fluctuations in the heavy-duty engine environment.
