The Genie 231303GT is a genuine OEM Extend B4 Sheave designed for the Genie SX-180 telescopic boom lift. As a direct OEM replacement, this sheave is manufactured to the same specifications as the original, ensuring proper rope or cable routing and tensioning within the boom extension system. Cross-reference part number 231303GT against your SX-180 parts manual to confirm it is the correct sheave for your machine's configuration before ordering.
Key Features
- Genuine OEM Construction — Manufactured to original Genie specifications, ensuring correct groove profile, dimensional accuracy, and material grade for long service life in the extension circuit.
- Direct OEM Replacement — Mounts in the same position as the original Extend B4 Sheave, allowing a straightforward swap without reworking the surrounding assembly.
- Specific SX-180 Fitment — Engineered specifically for the Genie SX-180 super-boom telescopic lift, so you can order with confidence knowing this is the correct application-matched component.
- Maintains Smooth Cable or Rope Travel — A correctly functioning sheave guides the extend cable cleanly through its travel, supporting consistent boom extension and retraction. A worn or damaged sheave can cause uneven cable wear, binding, or extension failure.
- Operational Safety Relevance — On a high-reach boom lift, reliable function of every extension component directly supports safe platform positioning. Replacing a worn sheave with a genuine OEM part keeps the extension system operating as Genie intended.
A sheave is a grooved wheel or pulley that guides a cable or rope as it moves through the boom extension system. The Extend B4 designation identifies this sheave's specific position within the SX-180's multi-stage extension assembly, where it keeps the cable aligned and reduces friction during boom travel. When a sheave wears, develops flat spots, or seizes, the cable can slip out of groove, wear prematurely, or bind — leading to sluggish or uncontrolled boom extension that must be addressed before the machine is returned to service.
