As a direct OEM replacement, this part is manufactured to the same specifications as the original, ensuring a proper fit within the steering or drive mechanism it serves. Cross-reference part number 87818GT against your TZ-34/20 parts manual to confirm it is the correct item for your serial range before ordering.
Key Features
- Genuine OEM Construction — Manufactured to original Genie specifications, ensuring the dimensional accuracy and material grade expected of a worm shaft in this application.
- Direct OEM Replacement — Installs in place of the original component with no additional modification, restoring the assembly to its correct operating condition.
- Confirmed Fitment — Sourced specifically for the Genie TZ-34/20 trailer-mounted articulating boom lift; always verify against your machine's parts manual before ordering.
- Maintains Drive Integrity — A sound worm shaft transmits motion smoothly and accurately through the gear assembly it serves; a worn or damaged shaft causes slippage, binding, or loss of function in the mechanism it drives.
A worm shaft is the driving element in a worm gear set, converting rotational input into controlled, reduced-speed output through meshing with a corresponding worm wheel. This geometry provides a high gear-reduction ratio and, in many configurations, a self-locking characteristic that prevents back-driving — an important property in positioning mechanisms on aerial equipment. When the worm shaft is worn, pitted, or damaged, the gear set loses efficiency and accuracy, and the function it controls becomes unreliable. Replacing the shaft with the correct OEM part restores the mesh geometry and ensures the assembly performs as intended.
