The Genie 58431GT is a genuine OEM Pump Shaft Seal Kit (Eaton) built for Genie GS scissor lifts and Z series articulating boom lifts. As a direct OEM replacement, this kit is manufactured to Genie's specifications, ensuring the part seals match the exact material grade, dimensions, and compression characteristics required by the Eaton pump assembly. Confirmed fitment includes the GS-3384, Z-51/30J, Z-45 XC, Z-45/25 IC, and Z-34/22 Bi-Energy — cross-reference part number 58431GT against your machine's parts manual to verify the correct application for your unit.
Key Features
- Correct Seal Material and Grade — Genuine OEM seals matched to the Eaton pump shaft's dimensional tolerances and compression requirements, preventing fluid weep at the shaft interface.
- Complete Kit — All seals needed for a full pump shaft reseal are included in a single kit, simplifying the repair and reducing the chance of omitting a component.
- Direct OEM Replacement — Built to Genie's specifications for a straight swap on the Eaton pump assembly, with no modification needed to the housing or shaft.
- Broad Genie Fitment — Fits the GS-3384 scissor lift and multiple Z series articulating booms including the Z-51/30J, Z-45 XC, Z-45/25 IC, and Z-34/22 Bi-Energy.
- Restores Pump Integrity — A worn or degraded pump shaft seal allows fluid to escape at the shaft, causing pressure loss and pump performance issues. Replacing the seals promptly restores correct operation.
- Operational Safety — On aerial lifts, a properly sealed pump is essential to maintaining consistent hydraulic output for lift and drive functions. Using the correct OEM seal kit supports the integrity of those systems.
A pump shaft seal kit contains the seals that prevent fluid from escaping around the rotating shaft where it exits the pump body. Over time, heat cycling and shaft rotation cause these seals to harden, crack, or lose their compression set, allowing fluid to weep past the shaft. Left unaddressed, this leads to fluid loss, reduced pump output, and potential damage to surrounding components. Replacing the full seal set at the first sign of shaft leakage is the correct remedy, and using a genuine OEM kit ensures the replacement seals conform to the clearances and material specifications the Eaton pump was designed around.
