Applications:
Is this air compressor compatible with your Detroit Diesel or Mercedes engine? Yes—designed for MBE4000 and OM460 engines used in Freightliner, Sterling, and vocational Mercedes platforms, this OEM-spec WABCO 85 mm compressor maintains consistent air pressure for brake and suspension systems. Engineered for high duty cycles, it delivers OE-grade reliability and cooling efficiency for extended uptime under North American operating conditions. The 4123520270 variant is nearly identical in dimensions and cooling configuration (85 mm × 62 mm, 352 cc) but features updated port geometry and ESS-equipped valve plate for later Euro V/VI engine emissions packages. Both interchange dimensionally, but verify ESS requirement before substitution.
