Replacement Hydraulic Pump Parts

Hydraulic pump components vary by design. Gear pumps may contain gears, wear plates, shafts, seals, and bearings. Vane pumps use cartridges and related internal parts, while axial piston pumps can include pistons, slippers, a cylinder block, valve or port plate, swash plate, bearings, and seals. The correct parts depend on the pump architecture and the machine’s exact configuration.

McCann supplies hydraulic pump parts through its parts counter and can order CASE parts through the CASE online parts store. New OEM, remanufactured exchange, and quality aftermarket options are available for equipment brands and models McCann services. Common service parts may be available for counter pickup, while complete pump assemblies are often sourced or transferred. Confirm availability, returns, warranty, and core terms before ordering.

Provide the machine make, model, serial number, and pump nameplate or tag information. The machine badge alone may not identify the correct pump because production variants and pump manufacturers can differ. McCann uses these details to check OEM information, supersessions, pump configuration, and available repair, remanufactured, or new replacement options.

Yes. Weak or slow hydraulics do not prove that the pump has failed. Pressure and flow testing can help distinguish pump wear from a mis-set relief valve, restricted suction line, aerated fluid, failing charge pump, leaking cylinder, or other downstream issue. For hydrostatic systems, charge pressure and drive pump and motor case drain flow should be checked against applicable OEM data.

A new OEM pump is supplied as a new replacement component through the applicable equipment or pump supplier. A remanufactured pump is rebuilt to OEM specification and may use a core exchange, with the core charge refunded when a rebuildable core is returned. Reman installations carry parts and labor warranty according to the supplied information, while other parts warranty terms should be confirmed in writing.

System flushing is strongly indicated after a pump failure because wear debris can circulate through the reservoir, lines, cooler, valves, cylinders, and motors. Reservoir cleaning and filter replacement help protect the replacement component. Fluid cleanliness can be assessed using ISO 4406 coding, and filter efficiency is associated with ISO 16889 multi-pass testing. The required procedure remains machine and failure specific.
