John Deere AKK10129 Auxiliary Hydraulic Axial Piston Pump

The John Deere AKK10129 Auxiliary Hydraulic Axial Piston Pump is characterized as a 75 cc pump for compatible auxiliary hydraulic systems. It serves as a mechanism for transforming mechanical drive power into hydraulic flow for those functions that perform outside of the propulsion system of the machine. An axial piston design allows for efficient fluid delivery in a compact unit; however, proper functioning requires the compatibility of the entire pump unit with the equipment.

The displacement is an important characteristic when selecting the right pump because it influences the theoretical volume flow for one revolution of the shaft. However, just a 75 cc capacity is not sufficient for the selection of a replacement. The AKK10129 part number, equipment model, serial number range, mounting face, drive shaft, direction of rotation, inlet and outlet ports, as well as any control ports must be verified. The pumps that appear identical may have different internal characteristics or port arrangement.

These Axial pumps have close internal clearances. Any contamination of oil can score the piston assembly and the valve plates, whereas aeration or restriction at the suction point will result in noise, heat, and low displacement. Prior to installing the replacement AKK10129, it is advisable to check the condition of the reservoir, filters, and the suction system. In case the pump being replaced was defective, the hydraulic circuit has to be cleaned so that any particles would not damage the replacement.

The device needs to be primed or lubricated following the instructions of the machine service manual before its operation. At first start up, a controlled load has to be used during the inspection by a technician of rotation, leaking, pressure reaction, and noise. An increase in temperature, instability in discharge or cavitation noise have to be investigated, and not considered normal bedding-in.
