The Genie 53959GT Lift Pump, 1.403 C.I. is a genuine OEM pump built for Genie S-60, S-65, S-80, and S-85 telescopic boom lifts. As a direct OEM replacement, this pump is sourced to Genie's original specifications, ensuring it matches the design and displacement of the unit it replaces. Cross-reference part number 53959GT against your machine's parts manual to confirm it is the correct pump for your serial range and configuration before ordering.
Key Features
- Genuine OEM Displacement Match — Built to the original 1.403 C.I. displacement specification, so fluid output and operating characteristics match what your machine was engineered to deliver.
- Direct OEM Replacement — Engineered to install in place of the original unit with no rework, using the same porting, mounting, and drive interface as the factory pump.
- Fits Key S-Series Telescopic Booms — Confirmed fitment for the Genie S-60, S-65, S-80, and S-85 telescopic boom lifts; verify against your parts manual for your specific serial number.
- Restores Lift Performance — A worn or failing pump causes sluggish or inconsistent boom movement. Replacing it with the correct OEM unit restores the fluid flow the lift circuit depends on for smooth, responsive operation.
- Operational Safety — Consistent pump output is essential for controlled boom extension and elevation on aerial work platforms. Using the correct OEM pump supports the predictable machine behavior operators rely on at height.
A lift pump moves fluid through the circuit that raises and extends the boom, converting mechanical drive into the fluid flow and pressure that powers the machine's lift functions. When a pump wears internally, it loses efficiency — output drops, movement becomes sluggish or uneven, and in advanced cases the boom may fail to hold position or respond properly to controls. Replacing the pump with the correct OEM part, matched to the original displacement, restores the fluid delivery the system requires and returns the machine to normal, dependable operation.
