The Wacker Neuson Key is a genuine OEM component designed for the MP20 and MP12 Single Direction Plates and the GS6503G and GS6500G screeds. As a factory-sourced part, it is manufactured to the exact tolerances Wacker Neuson specifies for these machines, ensuring a direct, correct-fit installation without guesswork. Confirm your model number against the fitment list below before ordering to make sure is the right key for your application.
Key Features
- Genuine OEM Fit and Finish — Manufactured to Wacker Neuson's exact dimensional spec, so the key seats fully and transmits torque the way it was designed to from day one.
- Direct Slot-In Replacement — Matches the original keyway profile of the mating shaft and hub, allowing a straightforward swap with standard hand tools.
- Confirmed Fitment Across Two Machine Families — Verified for MP20 and MP12 Single Direction Plates and GS6503G and GS6500G screeds, covering a broad range of Wacker Neuson compaction and finishing equipment.
- Positive Torque Transfer — A correctly fitted key locks the rotating component to its shaft, preventing slippage that would otherwise cause uneven compaction or screeding performance and accelerated wear on mating surfaces.
- Sourced Direct from Wacker Neuson — Carrying the OEM part number 5000408472 means you get the correct hardness grade and geometry — not a generic approximation — for a lasting repair.
A key is a small, precision-machined drive component that sits in a machined slot — called a keyway — between a rotating shaft and a hub, pulley, or drum. Its job is to lock those two parts together so they rotate as one unit, transferring power without slipping. If the key shears, deforms, or works loose, the driven component can spin independently of the shaft, resulting in a loss of drive, vibration, and rapid damage to the surrounding keyway surfaces. Replacing a worn or damaged key promptly with the correct OEM part restores full power transmission and prevents the more costly secondary damage that continued operation without a functioning key can cause.
