The Genie 1256182GT is a genuine OEM Flat Washer, 5/8, F436, HRD, ZAG designed for the wheel drive with brake assembly on a wide range of Genie telescopic and articulating boom lifts. As a direct OEM replacement, this washer meets the original engineering specifications for the wheel drive brake mounting configuration. It is compatible with Genie S and SX series telescopic boom lifts, Z and ZX series articulating boom lifts, and TZ series trailer-mounted booms. Note: machines with serial numbers 101 through 270 require two washers per screw — cross-reference part number 1256182GT against your parts manual to confirm the correct quantity for your specific unit before ordering.
Key Features
- Hardened OEM-Grade Construction — F436 structural specification with a hard zinc-alloy (ZAG) coating delivers the load-bearing capacity and corrosion resistance required in a wheel drive brake application.
- Direct Wheel Drive Brake Fitment — engineered specifically for the 60.2:1 wheel drive with brake assembly, this washer seats and torques correctly without shimming or adaptation.
- Serial Number Quantity Note — machines built with serial numbers 101 to 270 require two of these washers per screw; verify your serial number before ordering to ensure you receive the correct quantity.
- Wide Boom-Lift Compatibility — fits Genie S and SX series telescopic booms, Z and ZX series articulating booms, and TZ series trailer-mounted articulating booms, covering a broad range of Genie aerial equipment.
- Genuine OEM Part — sourced directly from Genie, this component is identical to the part installed at the factory, preserving the integrity of the wheel drive and brake system as originally assembled.
- Brake System Integrity — a correctly rated washer in this position ensures proper clamping force and load distribution across the brake assembly; using an undersized or incorrect-grade substitute can compromise braking performance and machine safety.
A flat washer in a wheel drive brake assembly does more than simply spread load — it distributes clamping force evenly across the mating surfaces, protecting the fastener and the housing from deformation under the high torque and dynamic stress of drive and braking cycles. In a boom lift application, where the wheel drive assembly must handle both propulsion and braking on grades and rough terrain, maintaining the correct washer grade and quantity is critical. Using an incorrect washer — whether the wrong hardness rating, coating, or number per fastener — can lead to fastener loosening, uneven brake engagement, or premature wear in the drive assembly.
