Key Features
- Genuine OEM Construction — Manufactured to Genie's original material and dimensional specifications, this kit includes seals and bearings sized precisely for the 4.5K Rotator assembly — not generic substitutes.
- Complete Service Kit — Includes both the seals and bearings needed for a full rotator rebuild in one part number, so technicians have everything required for the service in a single order.
- Broad Articulating Boom Fitment — Fits a wide range of Genie Z-series and TZ-series articulating boom lifts, including Z-45/25, Z-45/25J IC Power, Z-45/25J DC, Z-45/25J Bi-Energy, Z-34/22, Z-34/22 N, Z-34/22 IC, Z-34 IC, Z-51/30J, TZ-50, and TZ-50/30.
- Restored Rotator Integrity — Worn seals allow fluid to bypass the rotator and degrade rotation control, while a failed bearing introduces play and vibration. Replacing both restores smooth, controlled platform rotation.
- Platform Control Safety — The rotator is integral to accurate platform positioning at height. A correctly sealed and supported rotator keeps the platform responding predictably, which matters on every lift cycle.
The rotator on an articulating boom lift allows the platform to rotate independently of the boom, giving operators the ability to position themselves precisely at a work site without repositioning the machine. The 4.5K Rotator relies on its internal seals to maintain fluid pressure for rotation control and on its bearing to support the load and movement without play. When seals deteriorate they allow fluid to bypass the circuit, causing sluggish or inconsistent platform rotation; a worn bearing introduces unwanted movement that affects platform stability. Replacing the seals and bearing together with the correct kit restores the rotator to proper operating condition.
