Useful Information

Description and Purpose:

This Genuine Cummins Single Cylinder Air Brake Compressor, supplied under Part number: 4952756 and presented in new condition, provides controlled pneumatic output for heavy-duty braking. Designed as a water-cooled, engine-lubricated single-cylinder system, it delivers 145 PSI capability with a 3.35 in piston and 2.20 in stroke, supported by multiple connection threads like 3/4-16 UNF and M27×2 for precise air routing. Cross reference: 4952756RX

Why Replacement is Important:

A declining air source causes inconsistent pressure levels, placing higher stress on valves and reducing braking reliability.

Impact on Vehicle Performance:

A properly functioning air supply improves reservoir fill speed and maintains steady brake response on ISM, M11 and N14 platforms.

Manufacturer Information:

Cummins® supports long-term fleet reliability through components calibrated for precise flow control, emission stability, and consistent on-road performance.
