The Genie 35831GT is a genuine OEM Worm & Worm Shaft Assembly designed for Genie articulating and trailer-mounted boom lifts, including the TZ-34/20, Z-30/20HD, and Z-30/20. As a direct OEM replacement, this assembly is built to the same specifications as the original component, ensuring a proper fit within the machine's slewing or drive system without adaptation. Cross-reference part number 35831GT against your machine's parts manual to confirm fitment before ordering. Sourced directly through authorized channels, this assembly delivers the dependable performance that aerial lift work demands.
Key Features
- Genuine OEM Gear Integrity — Manufactured to Genie's original tolerancing for worm-gear mesh and shaft alignment, ensuring correct torque transfer without premature wear.
- Service Assembly Format — Supplied as a complete worm and worm shaft assembly, so installation replaces the worn gear set in a single service operation rather than sourcing individual components.
- Confirmed Fitment — Directly compatible with the TZ-34/20 trailer-mounted boom and Z-30/20 and Z-30/20HD articulating boom lifts.
- Restores Smooth, Controlled Movement — A correctly functioning worm gear assembly maintains smooth, load-bearing rotational motion; a worn or damaged set introduces backlash, uneven movement, and potential slewing failure.
- Aerial Lift Safety Relevance — The worm gear assembly is a load-bearing drive component. Maintaining it with a genuine OEM part supports the structural and operational integrity expected of elevated work platforms.
A worm and worm shaft assembly is a type of gear set in which a helical screw (the worm) meshes with a toothed wheel to transfer rotational motion and reduce speed while multiplying torque. In Genie boom lifts, this assembly is typically found within the slew or swing drive, controlling the side-to-side rotation of the boom. The self-locking nature of a worm gear is especially important in aerial applications, as it helps hold the boom's position under load without relying solely on braking systems. When the worm gear or shaft wears, operators may notice excessive play in the boom swing, abnormal noise during rotation, or a loss of smooth positional control — all of which point to the need for prompt replacement.
