The Genie 128858GT is a genuine OEM Retaining Washer, M16 built for the Genie Z-135/70 articulating boom lift. Sourced directly from Genie, this part meets the exact dimensional and material standards required for correct installation on your machine. Cross-reference part number 128858GT against your Z-135/70 parts manual to confirm it is the correct item for your specific unit before ordering.
Key Features
- Genuine OEM Material Conformity — Manufactured to Genie's dimensional specifications for the M16 fastener class, ensuring correct seating and load distribution at the installation point.
- Exact M16 Sizing — The M16 specification matches the mating hardware directly, so the washer installs without modification or shimming.
- Confirmed Fitment for Z-135/70 — Verified OEM fitment for the Genie Z-135/70 articulating boom lift; always confirm part number 128858GT against your serial-number-specific parts manual.
- Retaining Function Preserved — A correctly sized retaining washer keeps the fastener assembly secure under load and vibration; a worn or undersized washer can allow fastener migration and structural loosening over time.
A retaining washer is a load-spreading and fastener-securing component placed beneath a nut or bolt head to distribute clamping force across a wider surface area and prevent the fastener from pulling through or working loose under vibration and dynamic loads. On an articulating boom lift like the Z-135/70, where joints and pivot points are subject to continuous movement and significant mechanical stress, maintaining the integrity of every fastener assembly is essential to safe, stable operation. A damaged or missing retaining washer compromises the clamping joint it serves and should be replaced promptly with the correct OEM part.
