The Genie 58999GT is a genuine OEM Thrust Washer 33434GT built for Genie S-series telescopic boom lifts and Z-series articulating boom lifts, including the S-80, S-85, S-60, S-65, S-80 XC, S-85 XC, S-80 HF, S-85 HF, S-80X, and Z-80/60. As a genuine OEM component, this washer is manufactured to the same standards as the original part it replaces, ensuring dimensional accuracy and correct material grade. Cross-reference part number 58999GT and referenced assembly 33434GT against your machine's parts manual to confirm this is the correct washer for your unit before ordering.
Key Features
- Genuine OEM Material Grade — Manufactured to the same dimensional and material specifications as the original, ensuring correct load distribution and surface hardness for a thrust application.
- Direct Drop-In Fit — Matches the original mounting location and bearing surface geometry of assembly 33434GT, so installation follows the same procedure as the factory part.
- Broad Boom Lift Compatibility — Fits Genie S-series telescopic boom lifts and Z-series articulating boom lifts across multiple platform configurations, including XC and HF variants.
- Wear Prevention — A correctly seated thrust washer controls axial load between rotating and stationary components, preventing accelerated wear on adjacent bearing surfaces and the surrounding assembly.
- Operational Integrity — A worn or missing thrust washer can allow unwanted axial movement in the assembly it serves, leading to irregular operation and potential damage to connected components.
A thrust washer sits between two mating surfaces to absorb and distribute axial loads — forces that act along the axis of a rotating shaft or pivot. By providing a controlled bearing surface, it keeps components properly spaced and prevents metal-to-metal contact that would quickly wear down surrounding parts. When a thrust washer wears thin, cracks, or goes missing, the assembly it supports loses that load control, which can lead to play, noise, and progressive damage to adjacent components. Replacing a worn washer promptly with the correct OEM part restores proper spacing and protects the longevity of the surrounding assembly.
