Hydraulic Pump Rexroth R971063375 Hyundai Excavator – Product Details

The Rexroth R971063375 Hydraulic Pump is a high-performance replacement main pump designed for Hyundai mini excavators. This axial piston pump belongs to the AP2D28 series (full model designation: AP2D28LV1RS7-790-0) and serves as the primary hydraulic power source for 5–7 ton class machines including the R55-7, R60-5, and R60-7.

The AP2D28 is a compact, variable displacement tandem pump that delivers reliable hydraulic power for travel, swing, and working equipment circuits. It is engineered to meet OEM performance standards and provides a direct bolt-on replacement for the original Hyundai unit.

Compatible Hyundai Models

The R971063375 hydraulic pump is directly compatible with the following Hyundai excavators:

  • Hyundai R55-7 / R55-7A
  • Hyundai R60-5
  • Hyundai R60-7

These models are part of the Robex series of mini excavators widely used in construction, landscaping, and utility applications.

  • Grade Performance: Engineered to match Hyundai and Rexroth factory specifications for pressure, flow, and response.
  • Integrated Pilot Pump: The AP2D28LV1RS7 includes a built-in pilot gear pump, eliminating the need for a separate pilot unit and simplifying installation.
  • Negative Flow Control: Optimizes hydraulic flow based on demand, reducing fuel consumption and heat generation during operation.
  • Durable Construction: Features a robust cast iron housing, high-precision piston/cylinder assembly, and NOK seals for long service life in demanding conditions.
  • Direct Bolt-On Fit: Exact mounting dimensions and port locations ensure drop-in replacement without modification.

This hydraulic pump is the main hydraulic component for Hyundai R55-7 and R60-7 excavators, supplying hydraulic power to:

  • Travel motors (left and right)
  • Swing motor
  • Boom, arm, and bucket cylinders
  • Auxiliary hydraulic circuits
