John Deere RE240475 Hydraulic Axial Piston Pump

John Deere RE240475 Hydraulic Axial Piston Pump is an equipment-specific pump that takes the mechanical energy and converts it into hydraulic energy. John Deere defines it as an axial piston pump, while on another official product-page version, the specification of the tractor application is noted to be 63 cc/rev. The axial piston construction allows for an efficient power transmission and flow in the systems that demand a compact design and reliable pressure capacity.

According to John Deere, RE240475 is an original tier part. Dimensions of the published product are about 13 inches in length, 10.2 inches in width and 9.9 inches in height, with the listed weight being 71 lb. Those dimensions can help to handle the part during the installation process, however, they cannot be used as a replacement for fitment verification. The correct equipment model, serial numbers and exact part number must be checked.

Axial piston pumps are designed to operate with strict tolerances. Clean oil, proper viscosity, and free suction without any air leaks are vital. Contamination could lead to the damage of pistons, shoes, cylinder block, and valve surfaces. Poor suction, air leak, or cavitation will lead to noise and premature wear. In addition, excessive case pressure, wrong drain position, or high relief pressure can reduce the service life of an axial piston pump.

In the case of replacement of a failed pump, it is important to identify the cause of the malfunction and the overall state of the hydraulic circuit. Filters and oil may require replacement. In addition, metal contamination of the reservoir, cooler, hoses, and valves must be cleaned up. The new pump must be primed and put into operation under light load conditions. Pressure, flow rate, case leakage, temperature, and noise level must be observed before putting the machine back to work.
