The Wacker Neuson Cotter Pin is a genuine OEM component designed for GPSi3200 and GPSi4300 series portable inverter generators. As a direct OEM replacement, this cotter pin is manufactured to the same specifications as the original hardware installed at the factory, ensuring a precise drop-in fit with no guesswork. Sourced directly through authorized Wacker Neuson parts channels, the is the correct choice when you need confidence in the part you're installing. It is confirmed to fit multiple configurations across the GPSi3200 and GPSi4300 model lines.
Key Features
- OEM-Grade Retention Integrity — Manufactured to the same dimensional tolerances as the original, so the pin seats correctly and holds its fastened position under vibration and load.
- Direct Drop-In Installation — Replaces the original cotter pin without modification; installs the same way as the factory-fitted hardware for a clean, straightforward service.
- Broad GPSi Series Compatibility — Fits multiple build configurations of the GPSi3200 and GPSi4300 portable inverter generators, covering a wide range of serial variants across both model families.
- Prevents Fastener Loosening — A correctly functioning cotter pin locks clevis pins, axle pins, and similar fasteners in place; a worn or missing one allows critical connections to back out, leading to component failure or unsafe operation.
- Safety-Critical Fastening Hardware — Cotter pins are a locking safety feature in mechanical assemblies; using a genuine OEM replacement ensures the correct material grade and bend characteristics for secure, lasting retention.
A cotter pin is a small but essential piece of fastening hardware used to lock a clevis pin, shaft pin, or bolt in position, preventing it from backing out during operation. Once inserted through a drilled hole and bent open, it mechanically secures the assembly against vibration and movement. When a cotter pin is missing, broken, or deformed, the fastener it retains can work loose, causing connected components to shift, separate, or fail — often without warning.
