3971519 CUMMINS Single Cylinder, Air Compressor

This high-strength single cylinder air compressor serves as a critical component within the pneumatic system of heavy-duty engines. It is designed to provide consistent air pressure through a precise mechanical cycle, ensuring reliable operation under demanding industrial conditions.

The 3971519 model is the OE equivalent of the CUMMINS 3971519 air compressor used in CUMMINS ISBe and ISDe engine series. This component features a cylinder bore of Ø80.00 mm, a 45 mm stroke, and a swept volume of 225cm³. It is specifically designed for water-cooled applications with M26x1,5 air inlet and M2 even more robust port configurations to maintain system integrity.

Technicians can rely on this part for seamless integration during engine maintenance or complete system overhauls. The unit includes specialized ports such as M16x1,5 for water inlet/outlet and M26x1,5 for air, ensuring precise fitment within the engine block assembly.

When performing replacements, it is essential to verify the compatibility with specific engine variants like the LF45 or LF55 series to ensure optimal performance of the braking and pneumatic systems.
