The WABCO 911 153 020 R is a remanufactured single-cylinder air compressor designed for compatible 2010 Cummins ISC engine applications. The compressor is driven by the engine and supplies compressed air to the vehicle’s air reservoirs for operation of the air-brake system and other compatible pneumatic equipment. A properly functioning compressor is essential for maintaining normal pressure buildup, dependable brake response, and consistent operation of air-controlled components. WABCO remanufactured compressors are processed using controlled disassembly, cleaning, inspection, restoration, replacement, reassembly, and functional-testing procedures. Components that cannot be returned to the required specifications are replaced as part of the remanufacturing process. This unit provides a service replacement option for vehicles requiring the identified ISC 2010 compressor configuration. Before installation, technicians should verify the engine serial number, mounting flange, drive arrangement, air inlet and outlet ports, coolant connections, and applicable OE or remanufactured cross-reference.
