The Genie 77364GT is a genuine OEM Leveling Cylinder Seal Kit designed for Genie Z-series articulating boom lifts, including the Z-45/25J, Z-51/30J, Z-40/23N, and related variants. As a direct OEM replacement, this seal kit is manufactured to the same specifications as the original component, ensuring a consistent, accurate fit in the leveling cylinder. It is compatible across a broad range of Z-series models, including Bi-Energy, IC Power, DC, FE Hybrid, XC, and RJ configurations. Always cross-reference part number 77364GT against your machine's parts manual to confirm it is the correct kit for your specific unit before ordering.
Key Features
- Genuine OEM Sealing Materials — Manufactured by Genie to original material and dimensional specs, so seal profiles, durometer, and compression characteristics match the leveling cylinder exactly.
- Direct Cylinder Replacement — Engineered to install into the leveling cylinder without modification, restoring the original sealing interface on the first attempt.
- Broad Z-Series Compatibility — Fits a wide range of Genie articulating boom lifts across the Z-40, Z-45, and Z-51 families, including IC Power, DC, Bi-Energy, FE Hybrid, XC, and RJ variants.
- Restored Cylinder Integrity — A sound leveling cylinder seal keeps the platform level during operation. Worn or leaking seals allow fluid loss and can cause platform drift, which affects positioning accuracy and increases wear on surrounding components.
- Platform Leveling Safety Relevance — The leveling cylinder maintains a stable working platform at height. Maintaining proper seal condition is a key element of safe aerial work platform operation and helps keep the machine performing as designed.
The leveling cylinder on a Genie articulating boom lift keeps the work platform horizontal as the boom raises, lowers, and articulates. It relies on internal seals to hold fluid pressure and maintain consistent platform positioning throughout the lift cycle. When those seals wear, crack, or fail, fluid can bypass or weep past the seal faces, causing the platform to drift out of level or the cylinder to lose holding force. Replacing the seals with a correct OEM kit restores the cylinder's ability to maintain a stable, level platform — an essential requirement for safe and productive operation at height.
