The Genie 123187GT is a genuine OEM Chain Sheave designed for Genie GTH series telehandlers, including the GTH-844, GTH-842, and GTH-636. As a direct OEM replacement, this sheave is manufactured to the same standards as the original part, ensuring a correct fit without modification. It is confirmed for use across the GTH-844, GTH-842, and GTH-636, making it the dependable choice when the original component needs replacement.
Key Features
- Genuine OEM Construction — Manufactured to the same dimensional and material specifications as the original Genie factory part, ensuring proper engagement with the chain and surrounding components.
- Direct Replacement Fit — Engineered to install in place of the original Chain Sheave with no alteration to the machine required, keeping replacement straightforward.
- Confirmed Telehandler Fitment — Compatible with the Genie GTH-844, GTH-842, and GTH-636 telehandlers; cross-reference part number 123187GT against your machine's parts manual before ordering.
- Chain Guidance Integrity — A sound sheave keeps the chain properly tracked and tensioned; a worn or damaged sheave can cause chain misalignment, accelerated chain wear, and loss of smooth boom or carriage operation.
- Operational Confidence — Replacing a worn sheave with the correct OEM component restores proper load-handling and boom-extension function to the machine, keeping the telehandler performing as intended.
A chain sheave is a grooved wheel or pulley that guides and redirects the chain within the telehandler's boom or carriage system. It keeps the chain seated correctly, distributes load evenly across the links, and allows the chain to change direction with minimal friction. When a sheave wears, develops flat spots, or cracks, the chain can jump the groove, wear unevenly, or generate excessive noise — any of which signals that the sheave should be inspected and replaced. Installing the correct OEM sheave restores smooth, controlled chain movement and protects the chain itself from premature wear.
