Leading the way in Excavator Exchange Units!
HRD maintains an inventory of main pumps, swing pumps, swing motors, travel motors and main control valves of brand names like Kawasaki, Rexroth, Uchida-Hydromatik, Hitachi, Linde, KYB, Cat and Sundstrand to name a few. If you own an excavator with names like Cat, Komatsu, John Deere, Hitachi, Kobelco, Case, Hyundai, Daweoo or Kato Yutani, we may have your unit in stock ready to go. Each unit has been fully tested and set to OEM specifications with a written warranty and test report.
Each unit also comes with a complimentary oil sample bottle. We want to ensure that the components you have just purchased will last. By testing your machine's oil, we can let you know if you have contaminants in your systems that might damage your new component.
