Detroit RA4722002001 Variable Speed Water Pump – DD13 DD15 Remanufactured Crank Case Ventilation Always replace the pinion nutDetroit RA4722002001 is a factory remanufactured variable speed (electro viscous) water pump for Detroit Diesel DD13 and DD15 engines, replacing new pump A4722002001 EA4722002001 and superseded variants A4722001601 and A4722000701. The pump uses a viscous clutch between the pulley and impeller drive that the ECM modulates via the impeller speed sensor, reducing parasitic load when full coolant flow isn't required. Ships with the impeller speed sensor
