John Deere AL166639 Hydraulic Pump

John Deere AL166639 Hydraulic Pump is an original tier hydraulic pump available at John Deere, under catalog number AL166639. It is characterized as an oil pump. It is a specialized hydraulic pump, converting the drive power into hydraulic flow within the attached circuit. With the right choice and installation, this product guarantees stable hydraulic response, as it will supply oil to the control valves and actuators that will carry out the work of the equipment.

However, the publicly available John Deere listing only proves the identity of the product and does not include any information about its pressure, displacement, rotation, shaft and port. So, it is necessary to use the data on equipment compatibility and AL166639 part number in the choice of this pump. Also, it is essential to check the machine model, serial number and current catalogue of parts, as well as the label or casting of the removed pump.

Replacing the pump should be part of the overall hydraulic inspection. The technician needs to find out what the cause of the previous malfunction was, whether it was because of normal wear and tear, oil contamination, suction problems, excess pressure or something else wrong with the circuit. The reservoir, strainers, filters, hoses and connectors need to be checked. The contaminating metal needs to be cleaned out of the circuit before commissioning the new pump. Reusing contaminated oil or clogged filters reduces the longevity of the new pump.

Proper priming and startup will stop dry running. When installed, the pump needs to start up under light load. Oil levels, leaks, noise and heat need to be monitored. Hydraulic pressure and flow need to be measured using proper measuring equipment. All relief valves need to be set to the settings recommended by the equipment manufacturer. In case of poor performance, technicians need to check other valves, cylinders and components instead of just raising pressure.
