The Wacker Neuson Key is a genuine OEM component designed for the GPSi3200 and GPSi4300 Portable Inverter Generator series. Sourced directly from Wacker Neuson, this key meets the exact specifications of the original part, ensuring a correct, trouble-free installation. It is confirmed to fit multiple configurations across the GPSi3200 and GPSi4300 model lines, making it a straightforward choice when your generator needs this component replaced.
Key Features
- OEM-Matched Dimensions — Manufactured to the exact profile tolerances of the original, ensuring full engagement with mating shaft and hub surfaces without adjustment.
- Direct Drop-In Installation — Replaces the original key slot-for-slot with no filing or fitting required, restoring the shaft-to-component drive connection immediately.
- Broad GPSi Series Coverage — Fits GPSi3200 and GPSi4300 Portable Inverter Generators across multiple production configurations, covering a wide range of serial variants.
- Restored Power Transfer — A correctly sized key maintains positive torque transmission between shaft and driven component; a worn or missing key allows slippage that can damage both the shaft and the hub.
- Genuine Wacker Neuson Part — Backed by Wacker Neuson's OEM supply chain, part number 5000180406 is the same component installed at the factory, not a dimensionally similar substitute.
A key is a small, precisely dimensioned fastening element fitted into matching slots — called keyways — cut into a shaft and a mating component such as a gear, pulley, or flywheel hub. Its role is to lock the two parts together rotationally so that torque is transferred from the shaft to the driven component without slippage. When a key wears, shears, or goes missing entirely, the shaft spins independently of the driven component, causing an immediate loss of power transmission and potential scoring damage to the keyway surfaces that can make subsequent repairs more involved.
