Product Details
Product Function
The compressor is driven by the engine and supplies compressed air to the vehicle air system. Its primary role is to recharge the air reservoirs used by service brakes, parking brakes and related pneumatic equipment. Correct compressor output and installation are important for dependable pressure recovery.
OE Number and Cross References
Part number 3104324 is used as the primary compatibility reference. Commonly published cross references include 3103403, 3558163, 4059825, 4318214, 4952756 and WABCO reference 9111535200. Cross-reference information is provided for identification only and must be checked against the removed compressor.
Compatible Engine Applications
Published market references commonly list Cummins-compatible M11, N14, ISM and ISM11 engine applications. Some catalogs also associate related cross-reference configurations with QSM11, NH/NT855, K-series and other heavy-duty engine families. Because compressor versions may differ in drive, ports and mounting, buyers must confirm the exact engine configuration before purchase.
Reference Technical Configuration
Available reference data describes a single-cylinder, flange-mounted compressor with an approximately 85 mm bore, 56 mm stroke, 318 cc displacement and 18.7 CFM air delivery. Published port references include M27 x 2.0 STOR discharge, M10 x 1.0 STOR governor and 3/4-16 STOR water connections. These figures should be verified for the required configuration.
