The Genie 75339GT is a genuine OEM Perkins 1004-42 Alternator Mount Screw designed for Genie S-100, S-105, S-120, and S-125 telescopic boom lifts. As a direct OEM replacement, this screw is manufactured to the same specification as the original hardware, ensuring a correct fit to the alternator mounting position on Perkins 1004-42 equipped machines. Cross-reference part number 75339GT against your machine's parts manual to confirm it is the correct item for your serial range before ordering.
Key Features
- Genuine OEM Hardware Grade — Produced to Genie OEM specification, with the correct thread form, head type, and material grade for the alternator mounting application on Perkins 1004-42 engines.
- Direct-Fit Replacement — Installs directly into the alternator mounting position without modification, restoring the fastened assembly to its original condition.
- Confirmed Fitment for Large-Frame S-Series Booms — Compatible with the S-100, S-105, S-120, and S-125 telescopic boom lift models, covering the large-frame S-series range equipped with the Perkins 1004-42 engine.
- Keeps the Alternator Securely Located — A correctly torqued mount screw holds the alternator firmly in position. A stripped, damaged, or missing screw allows movement that can stress electrical connections and affect charging system performance.
- Genuine Part Assurance — Sourced directly through Genie's OEM supply chain, so you know the part leaving your shelf is the same item specified in the Genie parts manual.
The alternator mount screw secures the alternator to its bracket on the Perkins 1004-42 engine, keeping the unit fixed against vibration and load during machine operation. If this screw is worn, cross-threaded, or missing, the alternator can shift position, placing strain on drive belts and wiring connections and potentially interrupting the machine's charging circuit. Replacing a damaged fastener promptly with the correct OEM screw restores the secure, stable mount the alternator requires to function properly.
