The Genie 1274251GT is a genuine OEM Extend Sheave built for the Genie S-85 XC telescopic boom lift. As a direct OEM replacement, this sheave is manufactured to the same specifications as the original component, ensuring proper fitment and function in the boom extension system. Verify part number 1274251GT against your machine's parts manual to confirm this is the correct sheave for your unit before ordering.
Key Features
- Genuine OEM Construction — Manufactured to Genie's original design standards, with correct groove profile and dimensional tolerances for a sheave that seats and operates exactly as intended.
- Direct-Fit Replacement — Engineered to install in the same position as the original, with no rework or modification to mounting hardware required.
- Confirmed Fitment — Designed specifically for the Genie S-85 XC telescopic boom lift, so you can order with confidence that this is the right part for that machine.
- Smooth Cable Routing — A correctly functioning sheave guides the extension cable cleanly through its travel, supporting smooth and consistent boom extension and retraction.
- Operational Safety — A worn or damaged sheave can cause cable mis-tracking or uneven load on the extension system; replacing it with the correct OEM part restores proper cable management and safe boom operation.
A sheave is a grooved pulley wheel that guides and redirects a cable or rope as the boom extends and retracts. On a telescopic boom lift, the extend sheave keeps the extension cable properly aligned under load, allowing the boom sections to travel smoothly and evenly. When a sheave wears, develops flat spots, or cracks, it can cause the cable to slip off track, create uneven extension, or accelerate cable wear — all of which compromise the reliability and safety of the boom system. Replacing a worn sheave promptly with the correct OEM part keeps the extension mechanism operating as designed.
