The Genie 231304GT is a genuine OEM Extend Support B4 Sheave designed for the SX-150 and SX-180 telescopic boom lifts. As a direct OEM replacement, this sheave is manufactured to the same specifications as the original component, ensuring correct fit within the extension support assembly. Cross-reference part number 231304GT against your machine's parts manual to confirm it is the correct sheave position for your unit before ordering.
Key Features
- Genuine OEM Construction — Manufactured to original Genie specifications with consistent dimensional conformity, so the sheave seats and operates exactly as the factory-installed component did.
- Direct OEM Replacement — Replaces the original Extend Support B4 Sheave without modification, dropping into the existing assembly position on the SX-150 and SX-180.
- Targeted Fitment — Designed specifically for Genie SX-series super-boom telescopic lifts, covering the SX-150 and SX-180 models.
- Supports Smooth Boom Extension — A correctly functioning sheave guides the extension mechanism evenly; a worn or damaged sheave can cause uneven travel, increased wear on adjacent components, and compromised boom movement.
- Operational Safety — Proper function of the extension support assembly is critical to controlled boom travel at height. Replacing a failed sheave with the correct OEM part restores the integrity of this system.
A sheave is a grooved wheel or pulley that guides a cable, rope, or chain through a defined path within an assembly. In the extend support assembly of the SX-150 and SX-180 super-boom telescopic lifts, the B4 Sheave helps direct and support the extension mechanism as the boom travels in and out. When a sheave becomes worn, cracked, or seized, it can cause uneven cable wear, restricted boom travel, or increased stress on surrounding components — all of which point to the need for prompt replacement with the correct OEM part.
