The Genie 1264259GT is a genuine OEM Lock Washer, 1.0, ZAG designed for a broad range of Genie boom lifts and telehandlers. As a direct OEM replacement, this lock washer is manufactured to the same specifications as the original hardware installed at the factory, ensuring an exact match for the fastener assemblies it secures. This part is verified to fit models including the SX-105 XC, SX-125 XC, Z-40/23N, Z-45/25, Z-45/25J DC, Z-45/25J Bi-Energy, and GTH series telehandlers such as the GTH-1044, GTH-1056, GTH-1244, GTH-1256, and GTH-1544. Cross-reference part number 1264259GT against your Genie parts manual before ordering to confirm fitment for your specific serial number.
Key Features
- Genuine OEM Hardware Grade — Zinc-coated (ZAG) finish provides corrosion resistance suited to outdoor and rough-terrain operating environments, matching the original hardware specification.
- Direct Bolt-In Replacement — The 1.0 bore sizing aligns with the original fastener assembly, allowing this washer to seat and lock without rework or modification to surrounding hardware.
- Broad Genie Fitment — Fits Genie SX telescopic boom lifts, Z articulating boom lifts, and GTH telehandlers, covering multiple platform configurations across the Genie range.
- Maintains Joint Clamp Load — A correctly functioning lock washer prevents fastener back-off under vibration and load cycling — critical in aerial equipment where structural connections must hold torque over extended service periods.
- Structural Integrity Assurance — On boom lifts and telehandlers, loosened fasteners in structural, boom, or attachment points can create unsafe operating conditions; replacing worn or missing lock washers is a fundamental part of maintaining machine safety.
A lock washer sits beneath a nut or bolt head to resist loosening caused by vibration, dynamic loads, and thermal expansion cycles. The hardened, zinc-coated construction of this washer bites into both the fastener and the mating surface, maintaining clamping force across the joint. When a lock washer is missing, worn flat, or cracked, the fastener it secures can gradually back off, leading to play in the joint, accelerated wear on surrounding components, and — particularly on structural or boom connections — a potential loss of mechanical integrity that demands immediate attention.
