John Deere AN202916 Auxiliary Hydraulic Axial Piston Pump

John Deere AN202916 Auxiliary Hydraulic Axial Piston Pump has a displacement of 45.392 cc and is rated for use with compatible John Deere 4700 machines. Available dimensions are 6.8" tall, 7.5" wide and 10" long, weighing 28.15 lbs. This particular model of pump provides hydraulic flow for auxiliary applications with an axial piston rotating group.

Displacement is the theoretical volume moved per shaft revolution. Actual flow is dependent on operating speed, oil quality and internal efficiency. The full John Deere part number, range of equipment serial numbers, mount, shaft, rotation, ports and controls should be specified when ordering. An otherwise identical looking pump cannot be approved simply on visual inspection as the internal specifications and connections may vary.

Piston pumps need clean oil and proper inlet flow to function correctly. Small amounts of contaminants will wear down internal parts, while air leaks or restricted suction lines cause cavitation, excessive noise, overheating and decreased flow rates. The reservoir, oil, filters and hoses should be inspected prior to installation. Where an existing pump has failed internally, it is important that the entire hydraulic circuit be cleaned out and the oil changed.

The pump must be filled or greased following the equipment service procedure and must never be run without fluid. The first run must be done under light load and the rotation, leaks, noise, pressure response and temperature monitored. Testing the system is important since poor performance of the auxiliary could arise due to problems with the valve, actuator, hose or controller rather than the pump alone.

Provide us the machine model, serial number, current pump part number and clear photos of the ports, shaft and mounting surface before shipping. It is recommended to keep the old pump until the replacement is verified, installed and commissioned successfully. We supply aftermarket new-condition John Deere AN202916 Auxiliary Hydraulic Axial Piston Pumps and offer independent repair, testing, servicing, troubleshooting and installation services.
