The Genie 74375GT is a genuine OEM Thrust Washer, Torque Hub designed for Z-34 and Z-45 series articulating boom lifts. Sourced directly from Genie, this component meets the exact material and dimensional requirements set at the time of manufacture, ensuring it seats and functions the same way as the part it replaces. Confirmed fitment includes the Z-34/22 N, Z-34/22 DC, Z-34/22 Bi-Energy, Z-45/22, Z-45/25J IC Power, Z-45/25, Z-45/25J DC, Z-45/25J Bi-Energy, and Z-34 IC. Cross-reference part number 74375GT against your Genie parts manual before ordering to confirm applicability to your specific unit.
Key Features
- Genuine OEM Material Grade — Manufactured to the same hardness and surface-finish tolerances as the original, maintaining the correct load-bearing characteristics within the torque hub assembly.
- Drop-In Hub Fit — Engineered to the exact profile of the 74097 torque hub, seating correctly against mating surfaces without rework or shimming.
- Broad Z-Series Coverage — Fits a full range of Genie Z-34 and Z-45 articulating boom lifts, including IC Power, DC, and Bi-Energy variants, making it a practical stock item for fleets running mixed configurations.
- Sustained Drive-Wheel Performance — A correctly seated thrust washer controls axial load within the hub and prevents premature bearing wear, keeping drive performance consistent across the machine's service life.
- Structural Safety Relevance — The torque hub transmits propulsion and positioning forces on an aerial boom lift; a worn or failed thrust washer can lead to hub play that affects machine stability and safe operation at height.
A thrust washer is a flat bearing element positioned within the torque hub assembly to absorb and distribute axial (side-to-side) loads generated during drive and steering. In an articulating boom lift, the torque hub works continuously as the machine travels and positions itself, and the thrust washer prevents metal-to-metal contact between rotating and stationary hub components. When the washer wears thin or deforms, excessive play develops inside the hub, which can cause uneven tire wear, noisy operation, and — in more severe cases — loss of precise drive control that is critical when maneuvering a boom lift on a jobsite.
