John Deere KV13512 Hydraulic Gear Pump

John Deere KV13512 Hydraulic Gear Pump is a small fixed-delivery pump suitable for John Deere 240 and 250 machinery. This pump has a weight of 5.88 lb and is 5.7 inches high, 6.6 inches wide and 6.9 inches long. It is a gear pump, meaning that meshing gears are used to transport the hydraulic fluid from the inlet to the outlet when the shaft rotates.

Even if a gear pump is simple mechanically, its replacement demands caution. KV13512, the model of the equipment and the right range of serial numbers have to be determined. The rotation direction, mounting face, shaft, inlet and outlet locations, and drive connection have to be identical to those of the existing pump installation. Otherwise, a change of ports or incorrect rotation will not allow adequate hydraulic oil supply and will ruin the pump shortly after it is started.

Wear causes higher internal leakage, thus delivering less hydraulic fluid and slowing down machine functions due to heated oil. Noises can occur because of a blocked suction line, air leakages, low level of fluid in the reservoir or viscosity of the oil that is too great for the starting temperature. Before the replacement of the pump,technicians should inspect the reservoir, filter, suction hose, fittings and relief valve.

There shouldn’t be any restriction in turning the shaft or coupling. Also, there should not be any misalignment. Ensure that the pump is filled up with the proper hydraulic oil or use the machine service procedures for priming the pump. Start operating the pump at light loads while checking for leaks, noise, flow reaction, and temperature of the pump. Do not increase the pressure of the pump but measure the pressure.

Prior to delivery, please provide the make and model of the machine along with the serial number, the part number of the pump you have removed and the photographs of the ports, shaft, and mounting face of the pump. This will ensure that we do not send a visually identical but incompatible pump. It would be ideal if you could keep the pump you have removed until you have successfully installed the new pump.
