The Genie 45873GT is a genuine OEM Seal/Bearing Kit designed for Genie S-series telescopic boom lifts and Z-series articulating boom lifts, including the S-40, S-45, Z-34/22, Z-45/25, and Z-30/20 N families across a wide range of variants. As a genuine OEM kit, this assembly includes components 45043 and 54840, engineered to Genie's original specifications so the replacement matches exactly what came on your machine. Cross-reference part number 45873GT against your machine's parts manual to confirm it is the correct kit for your specific model and serial range before ordering.
Key Features
- Genuine OEM Construction — Manufactured to Genie's original material and dimensional specifications, so seals compress correctly and the bearing seats without modification.
- Complete Kit — Includes both components (45043 and 54840) in a single part number, so you have everything needed for a proper restoration without sourcing parts individually.
- Broad Boom Lift Coverage — Fits a wide range of Genie S-series telescopic and Z-series articulating boom lifts, including IC Power, DC, Bi-Energy, and rough-terrain variants.
- Restored Integrity — A worn seal allows fluid to weep past the joint while a degraded bearing introduces play and vibration; replacing both together restores proper movement and sealing at the assembly.
- Aerial Lift Reliability — On boom lifts, a failed seal or bearing at a pivot or cylinder assembly can affect platform movement and safe operation; using the correct OEM kit keeps the assembly performing as designed.
A seal and bearing kit addresses two common wear points in a single service event. The seals prevent fluid from escaping the assembly and keep contaminants out, while the bearing supports the rotating or pivoting components and controls play between mating parts. When either element wears, the assembly can develop leaks, irregular movement, or noise that worsens over time. Replacing the seal and bearing together — rather than one at a time — restores the assembly to proper operating condition and avoids a repeat teardown shortly after. Confirm part number 45873GT against your machine's parts manual before ordering to be certain this kit applies to your specific unit.
