John Deere AN405049 Picking Unit Drive RH Hydraulic Pump

John Deere AN405049 Picking Unit Drive RH Hydraulic Pump is a machine-specific right-hand hydraulic pump utilized in compatible picking unit drive circuits. The available data provides details of 60 cc axial piston design, weighs 120 lb, and measures 14 inches high, 15.25 inches wide and 20.25 inches long. The RH component is an essential part of the pump’s identification and it must never be regarded as a small labeling since the side, rotation, porting, and mounting influence installation.

The pump transforms the mechanical energy to hydraulic fluid flow in the picking unit drive circuit. The 60 cc displacement determines theoretical flow per revolution; however, the actual operational flow is dependent on shaft speed and volumetric efficiency. Replacements must include confirmation of AN405049, machine model, serial number range, RH location, shaft, mounting face, rotation, ports, and all connecting lines. Other than that, a LH pump or a visually identical one may not provide necessary alignment or hydraulic flow direction.

Prior to removal, it would be useful to note hose placement and indicate the connections to ensure that the unit will be installed correctly. Drive coupling, shaft and mounting should be checked for any signs of wear or misalignment. In case the failure led to the replacement of the pump, contamination of the hydraulic circuit should be ruled out, and it should be properly cleaned. New filters and the right type of oil help to ensure that the piston assembly and valves in the new pump are protected.

The commissioning should be started in the controlled environment. The unit needs to be primed as necessary, there should be no resistance in the suction line, and its rotation should be tested prior to being loaded. Technicians need to watch out for any leaks, noise, delivery rate, pressure response and temperature. Testing of the entire hydraulic circuit can help distinguish whether the pump is the source of the problem or another element.

Please provide the following information prior to dispatch: model of the machine, its serial number, number of the old pump and photos of ports, shaft and mounting face of the pump. This will minimize the chance of ordering a unit that looks similar, but is not compatible with your needs. If possible, keep the old pump on hand until installation of the replacement pump is complete.
