4936218 CUMMINS QSL9 Single Cylinder, Air Compressor

This single cylinder air compressor is engineered to provide reliable pneumatic pressure within heavy commercial vehicle engine systems. Designed for high-demand environments, the component utilizes a robust single-cylinder architecture to ensure consistent air output and long-term operational stability. The unit is specifically optimized for water-cooled applications to maintain optimal thermal regulation during intensive service cycles.

4936218 is the OE-equivalent CUMMINS 4936218 single cylinder air compressor used in the CUMMINS QSL9 and CUMSIN QSL engine systems. This part ensures seamless integration with the original engine specifications, maintaining the required pressure standards for heavy commercial vehicle operation. The precision engineering of the Ø85.00 bore and 56 mm stroke provides the necessary volumetric efficiency required for high-output performance.

For workshop technicians performing engine maintenance or system overhauls, this compressor offers straightforward installation with standardized port configurations. The unit features a Ø25 air inlet port and an M27x2 air outlet port, alongside a M10x1 unloader port. The water cooling system utilizes 3/4" - 16 UNF connections for both inlet and outlet to ensure stable temperature management during operation.

Maintaining regular checks on the water cooling paths and ensuring the integrity of the M27x2 and M10x1 connections is essential for preventing thermal-related performance drops. This component is built to meet the rigorous demands of the heavy commercial vehicle sector, providing a durable solution for fleet managers and service professionals seeking reliable engine-driven air compression.
