The Wacker Neuson is a genuine OEM Cotter Pin designed for the GV2500A, GV5000A, GV7000A, and GV5003A/GV7003A series portable generators, as well as the GS12Ai model. Sourced directly through Wacker Neuson's authorized parts channel, this cotter pin is an exact match to the original hardware installed at the factory. It fits across the full GV-series portable generator lineup, covering both 60Hz and 50Hz configurations. When you need a straightforward, specification-correct replacement, part number is the part to order.
Key Features
- Genuine OEM Hardware Spec — Manufactured to the exact material grade and dimensional tolerances of the original fastener, ensuring the pin seats and retains correctly without play or premature shear.
- Drop-In Installation — Installs directly into the existing pin bore with no reworking of the surrounding components, matching the original clevis or shaft geometry of the GV-series generator assembly.
- Broad GV-Series Coverage — Confirmed fitment across the GV2500A, GV5000A, GV7000A, GV5003A, GV7003A, and GS12Ai portable generator models in both 50Hz and 60Hz variants.
- Mechanical Retention Integrity — A correctly installed cotter pin locks a shaft, bolt, or clevis pin in place under vibration and load; a missing or deformed pin can allow connected components to shift, loosen, or disengage during operation.
- Safety-Critical Fastener — As a retaining element in rotating or load-bearing assemblies, the cotter pin directly prevents unintended disassembly; always replace a bent or removed cotter pin before returning the generator to service.
A cotter pin is a small split-pin fastener inserted through a drilled hole in a shaft or bolt to prevent a mating nut, clevis pin, or retaining collar from backing out during operation. On portable generators like the GV-series, these pins are used in control linkages, engine-side connections, and other assemblies subjected to vibration during run cycles. When a cotter pin is missing, bent beyond reuse, or broken, the component it secures can work loose, leading to misalignment, mechanical noise, or loss of function in the affected assembly. Replacing it promptly with the correct OEM part restores the retaining function and keeps the surrounding hardware properly secured.
