The Genie 231302GT is a genuine OEM Extend B3 Sheave built for Genie SX-series super-boom telescopic lifts, specifically the SX-150, SX-180, and SX-135 XC. As a direct OEM replacement, this sheave is manufactured to the same specifications as the original, ensuring proper fitment and correct operation within the extension system it serves. Cross-reference part number 231302GT against your machine's parts manual to confirm it is the correct sheave for your unit before ordering.
Key Features
- Genuine OEM Construction — Manufactured to original Genie specifications, with the dimensional accuracy and material grade required for a load-bearing sheave in a high-reach boom application.
- Direct OEM Replacement — Designed to install in place of the original Extend B3 Sheave with no rework to the surrounding assembly.
- Confirmed SX-Series Fitment — Compatible with the SX-150, SX-180, and SX-135 XC super-boom telescopic lifts, Genie's tallest-reaching boom platform.
- Maintains Extension Performance — A sound sheave keeps the cable or chain routed correctly through the extension stage; a worn or damaged sheave can cause uneven extension, premature cable wear, or loss of smooth boom travel.
- Operational Safety Relevance — Sheaves in a boom extension system are load-path components. Using a correctly specified OEM replacement supports the structural integrity of the boom's extension function at height.
A sheave is a grooved pulley wheel that guides a cable or chain through a defined path as the boom extends and retracts. In a multi-stage telescopic boom like the SX series, each sheave stage multiplies the travel of the extension cylinder, allowing the boom to reach full height smoothly and with controlled force. When a sheave wears, cracks, or seizes, the cable can slip from its groove, wear unevenly, or bind — leading to sluggish extension, increased stress on surrounding components, and potential failure of the extension stage. Replacing a worn Extend B3 Sheave with the correct OEM part restores proper cable tracking and smooth, reliable boom travel.
