The Genie 139308GT Swing Motor Complete is a genuine OEM assembly built for Genie S and SX telescopic boom lifts and Z and ZX articulating boom lifts. As a factory-sourced component, this assembly meets the original design and performance requirements for the machines it serves. This part fits a broad range of Genie boom lift models including the S-60, S-60 XC, S-65, S-65 TRAX, S-80, S-80 XC, S-85, S-85 XC, SX-135 XC, SX-180, Z-62/40, Z-80/60, Z-135/70, ZX-135/70, and additional variants — cross-reference part number 139308GT against your machine's parts manual to confirm this is the correct assembly for your unit.
Key Features
- Genuine OEM Assembly — Sourced directly from Genie, this complete swing motor assembly is built to the same dimensional and performance standards as the original unit it replaces.
- Complete Drop-In Assembly — Supplied as a complete unit, this assembly is ready to install without the need to source individual sub-components separately.
- Broad Boom Lift Coverage — Fits a wide range of Genie S, SX, Z, and ZX series boom lifts, making it a practical stocking item for fleets running multiple Genie models.
- Turntable Rotation Integrity — The swing motor drives rotation of the machine's turntable. A worn or failed unit can result in sluggish, uneven, or inoperable upper-structure rotation, taking the machine out of service.
- Aerial Work Safety — Proper turntable function is essential to controlled positioning of the boom and platform. Replacing a failing swing motor with a correct OEM assembly helps maintain the machine's intended operating behavior at height.
The swing motor is the drive component responsible for rotating the machine's turntable — the upper structure that carries the boom, platform, and controls — relative to the chassis. This rotation allows the operator to swing the boom left or right to position the platform precisely over the work area. When the swing motor wears out or fails, turntable movement becomes unreliable or stops entirely, preventing the machine from being positioned safely and effectively. Replacing it with the correct complete assembly restores full rotational function and returns the machine to service.
