John Deere A-AR101807 50 cc/rev Hydraulic Radial Piston Pump

John Deere A-AR101807 Hydraulic Radial Piston Pump is specified by A&I Products as a replacement pump with 50 cc/rev displacement. It is used for converting mechanical energy into hydraulic power for the machine circuit. Such a radial piston pump is appropriate for controlled high-pressure application, whereas the indicated displacement is the theoretical oil volume pumped on each shaft revolution.

The 50 cc/rev displacement is used to calculate the theoretical flow rate at a certain drive speed, which depends on pressure, oil temperature, condition and volumetric efficiency of the pump. Therefore, any replacement selection should ensure that the correct A-AR101807 part number is used. The information about the equipment model, serial number range, mounting, shaft, rotation, ports and drive connection should be verified.

Radial piston pumps must use clean oil since their internal surfaces and valves work with close tolerances. Dust increases wear and leakage inside the pump. Water decreases the lubricating effect and may induce corrosion; if air enters on the suction side, there is a danger of cavitation and pressure fluctuations. The strainer blockage, insufficient oil level, or damage to the suction hose might create noise, heat, and decreased hydraulic responsiveness.

If the previous pump had some internal defects, then replacing the pump alone might expose the replacement to a problem. The reservoir, the hoses, the cooler, and the valves have to be checked for any foreign matter. It is necessary to change filters, oil, and check the suction line for any restriction or air leak. It is also important to check drive components and alignment. After priming, the pump has to be started with minimum load and check its proper rotation, pressure and flow rates, temperature, and leaks.
