The WABCO 911 153 014 R is a remanufactured single-cylinder air compressor intended for compatible 2007 Cummins ISB high-mount engine applications. This engine-driven component generates compressed air for the commercial vehicle’s air-brake system and may supply other compatible pneumatic equipment installed on the vehicle. The high-mount configuration identifies the compressor’s application and installation arrangement, making accurate verification essential when replacing a similar low-mount unit. WABCO remanufactured compressors undergo a controlled process that includes disassembly, cleaning, inspection, machining or replacement of components as necessary, reassembly, and functional testing. This process is intended to restore dependable air delivery while providing a service replacement for the original compressor. Correct compressor operation supports normal reservoir pressure buildup and reliable braking-system response. Confirm the engine serial number, mounting position, drive arrangement, ports, cooling connections, and OE cross-reference before ordering or installation.
