The Genie 99174GT is a genuine OEM Pin, 0.75 Dia x 8.75 Lg, Chamfer built for Genie TZ trailer-mounted articulating boom lifts and Z-series articulating boom lifts. As a direct OEM replacement, this pin is manufactured to the same dimensional and material standards as the original component installed at the factory. It is confirmed to fit TZ-34/20, TZ-50/30, TZ-50, Z-45/25, Z-45/25J IC Power, Z-45/25J DC, Z-45/25J Bi-Energy, Z-45/25 IC, and Z-45/25J IC models — verify part number 99174GT against your machine's parts manual to confirm it is correct for your unit.
Key Features
- OEM-Grade Material and Dimensioning — Manufactured to Genie's original diameter and length specification (0.75 in diameter × 8.75 in length) with a chamfered end for consistent, repeatable assembly.
- Exact-Profile Replacement — The chamfer and precise shank dimensions allow this pin to seat correctly in its mating bores without additional fitting or modification.
- Broad Articulating Boom Fitment — Fits multiple Z-45/25 variants and TZ trailer-mounted articulating boom lifts across IC Power, DC, and Bi-Energy configurations.
- Structural Retention Function — Correctly sized pins maintain the alignment and load-bearing integrity of the pivot points they secure; an undersized or worn pin introduces play that accelerates wear on surrounding components.
- Genuine Genie OEM Part — Supplied directly in the Genie OEM parts program, ensuring traceability and compatibility with the machines listed above.
A pin of this type serves as a structural pivot or retention fastener at a hinged or articulating joint within the boom structure. It carries shear loads across the joint, holding connected components in correct alignment during boom movement and under load. When a pin wears, corrodes, or is lost entirely, the joint develops unwanted movement that places abnormal stress on surrounding hardware — including the bores, retaining rings, and structural members it passes through. Replacing a worn or damaged pin with the correct OEM part restores the joint to its designed geometry and prevents accelerated wear from propagating to adjacent components.
