4936218 CUMMINS ISC Single Cylinder, Air Compressor

This single cylinder air compressor is engineered to provide reliable pneumatic pressure within heavy-duty engine systems. Designed with a precision 85.00 mm cylinder bore and a 56 mm stroke, the unit delivers a swept volume of 318cm³ to maintain consistent operation. Its water-cooled architecture ensures optimal thermal management during intensive heavy-duty cycles, making it an essential component for engine performance.

4936218 is the OE-equivalent single cylinder air compressor used in the CUMMINS ISC engine. This part is specifically designed to meet the rigorous demands of heavy commercial vehicle applications where reliability is paramount. By utilizing high-strength components and a water-cooled valve plate design, it maintains structural integrity under high-pressure environments.

For workshop technicians and fleet managers, installation requires attention to the specific port dimensions: a Ø25 air inlet port, an M27x2 air outlet port, and an M10x1 air unloader port. The water inlet and outlet ports use 3/4" - 16 UNF threads to ensure a secure fit within the cooling circuit. Proper maintenance of the cooling lines is essential to prevent overheating and ensure the long-term durability of the compressor system.

This component is a critical part of the air brake and engine pneumatic system, ensuring that the vehicle's air-driven functions remain responsive. Given its technical specifications and compatibility with CUMMINS systems, it serves as a vital replacement part for maintaining fleet uptime and operational safety.
