The Genie 75645GT is a genuine OEM Hydraulic Tank, 55 Gallon, built for the Genie S-120HD telescopic boom lift. Sourced directly from Genie, this tank meets all original design and material specifications for the S-120HD, ensuring a correct, confidence-inspiring fit. As a genuine OEM part, it is manufactured to the same standards as the tank installed at the factory, giving you an exact replacement when the original is damaged, leaking, or beyond service life. Cross-reference part number 75645GT against your S-120HD parts manual before ordering to confirm it is the correct tank for your machine's serial number range.
Key Features
- Genuine OEM Construction — Manufactured to Genie's original material and dimensional specifications, ensuring the tank walls, fittings, and mounting points match the design intent for the S-120HD exactly.
- Direct-Fit Replacement — Engineered as a drop-in replacement for the S-120HD; mounting brackets, port locations, and 55-gallon capacity match the original so no fabrication or adaptation is needed.
- Model-Specific Fitment — Confirmed fitment for the Genie S-120HD telescopic boom lift; verify the part number against your machine's parts manual to ensure compatibility with your serial number.
- Fluid Capacity Integrity — The correct 55-gallon volume maintains the hydraulic fluid reserve the S-120HD relies on for consistent boom extension, lift function, and overall machine response across a full work cycle.
- Leak-Free Service Life — A sound, undamaged tank prevents fluid loss that would otherwise cause erratic machine performance, unplanned shutdowns, or contamination of the hydraulic circuit it serves.
A hydraulic tank stores and conditions the fluid that powers every hydraulic function on the machine — from boom extension and lift to platform leveling and drive. It provides reservoir volume to accommodate fluid displacement as cylinders extend and retract, and it allows heat to dissipate and air to separate from the fluid between work cycles. A cracked, corroded, or leaking tank compromises fluid level, introduces contamination, and can cause erratic or failed hydraulic response across all functions; replacing it promptly with the correct OEM part restores the system to proper operating condition.
