The Genie 993890GT is a genuine OEM Lock Washer, 5/8 ZP designed for AL4000 and AL5000 Genie light towers. As a factory-sourced component, this washer matches the original specifications used during assembly, ensuring a correct, consistent fit within the fastener stack. It is a direct replacement for the original hardware on compatible units — confirm part number 993890GT against your machine's parts manual before ordering.
Key Features
- Confirmed Fitment — Designed for AL4000 and AL5000 Genie light towers; always cross-reference 993890GT against your unit's parts manual to confirm the correct application.
- Fastener Integrity — A lock washer in good condition maintains clamping force under vibration, preventing fastener loosening during transport and operation. A failed or missing washer allows hardware to back out, creating loose assemblies that require more frequent inspection and retightening.
A lock washer is a hardened, split or serrated ring placed under a nut or bolt head to resist loosening caused by vibration and dynamic loads. As the fastener is tightened, the washer bites into both the mating surface and the fastener, maintaining clamping load even when the machine is subject to road vibration or generator-induced movement. When a lock washer is deformed, flattened, or corroded, it loses its spring tension and the fastener it secures can work loose over time. Replacing a worn lock washer with the correct OEM part restores the original clamping integrity at that joint.
