Rexroth A4FO500 Hydraulic Pump - Complete Parts and Repair Kit
Product Overview
The Rexroth A4FO500 is a bent-axis axial piston pump from the A4FO series, designed for high-pressure open-circuit mobile and industrial hydraulic systems. With a displacement of 500 cc/rev, it is one of the larger pumps in the Rexroth lineup and is commonly used in heavy construction machinery, mining equipment, large excavators, and industrial hydraulic presses that demand high flow and sustained pressure under continuous load.
The A4FO series uses a bent-axis design rather than a swash plate, which gives it high mechanical efficiency and robust performance in demanding applications. We supply both complete A4FO500 pumps and the internal wear components that need replacement when the pump starts losing pressure, making noise, or showing signs of internal leakage.
What's Inside the Rebuild Kit
The A4FO500 repair kit contains 9 core components:
Cylinder block (precision-honed bore)
Valve plate (lapped sealing surface)
9 pistons (heat-treated for hardness)
Retainer plate
Ball guide
Drive shaft
Thrust plate
4 retainers
4 swash plate components
These are the parts that wear out between 8,000 and 12,000 hours of operation. The cylinder block bore develops scoring, the valve plate pits, the piston seals lose tension, and the thrust plate and swash surfaces develop play. Replacing these components restores the pump to near-new performance.
