The Genie 1275747GT is a genuine OEM Hydraulic Piston Pump, M46, Hi Current designed for Genie S-series telescopic boom lifts, GS-series scissor lifts, and Z-series articulating boom lifts. As a direct OEM replacement, this pump is built to the same specifications as the original unit and integrates directly into the hydraulic circuit it serves on the listed machines. Cross-reference part number 1275747GT against your machine's parts manual to confirm it is the correct pump for your specific unit before ordering. Compatible models include the S-60, S-65, S-60X, S-65 TRAX, GS-3384, GS-3390, GS-4390, GS-5390, Z-45/25, and Z-45/25J IC Power.
Key Features
- Genuine OEM Hydraulic Performance — Built to Genie OEM specifications, this piston pump maintains the correct flow rate and pressure output required by the hydraulic circuit it serves, ensuring the machine operates as designed.
- M46 Hi Current Piston Design — The M46 Hi Current piston configuration delivers the displacement and duty-cycle capability demanded by high-current hydraulic applications across the supported equipment families.
- Direct-Fit Replacement — Engineered to match the original mounting interface and port configuration, this pump installs into the existing hydraulic system without adaptation or modification to lines or fittings.
- Broad Genie Family Coverage — A single part number covers S-series telescopic booms, GS-series scissor lifts, and Z-series articulating booms, making it a well-supported part for mixed fleets.
- Operational Integrity — A failing hydraulic piston pump causes sluggish or unresponsive lift and drive functions. Replacing it with a correctly specified OEM pump restores full system pressure and consistent machine response.
- Safety-Critical System Component — On aerial work platforms, hydraulic system integrity is directly tied to safe platform positioning and load handling. Using a genuine OEM pump ensures the circuit performs within designed safety parameters.
A hydraulic piston pump is the heart of a machine's hydraulic system, converting mechanical power into pressurized fluid flow that drives the lift, extension, and drive functions of the equipment. The M46 Hi Current designation indicates this pump is rated for higher electrical current demand, making it suited to the power requirements of the machines it serves. When a piston pump wears or fails, the result is reduced system pressure, slow or erratic machine movement, and in severe cases a complete loss of function — conditions that take the machine out of service and create unsafe working conditions. Replacing the pump promptly with the correct OEM part, confirmed by cross-referencing part number 1275747GT in your Genie parts manual, restores normal hydraulic output and returns the machine to safe, full operation.
