The Wacker Neuson Key is a genuine OEM Key designed for the BS50-4As, BS60-4As, BS70-4As, BS65-4As, BS72-4As, BS62-4A, and BS68-4A series four-stroke rammers. As a direct OEM replacement, this part is manufactured to the same standards as the original component that left the factory, ensuring a correct, trouble-free installation every time. Sourced directly through authorized Wacker Neuson supply channels, part covers an extensive range of BS-series rammer configurations including US, CN, and international variants. If you are servicing or rebuilding any of the covered BS-series models, this is the correct key to specify.
Key Features
- OEM-Grade Dimensional Accuracy — Manufactured to exact tolerances so the key seats fully in its keyway without rocking, binding, or requiring filing to fit.
- Drop-In Installation — Matches the original profile and size, allowing direct installation into the existing keyway without additional machining or adaptation.
- Broad BS-Series Coverage — Compatible with BS50-4As, BS60-4As, BS62-4A, BS65-4As, BS68-4A, BS70-4As, and BS72-4As rammer models across US, CN, and standard international configurations.
- Torque Transmission Integrity — A correctly fitted key locks the rotating component to its shaft, ensuring full power transfer from the engine to the drive assembly and preventing slippage under load.
- Genuine Wacker Neuson Part — Supplied as an authentic OEM component under part number 5100031004, giving you confidence that the part matches the original engineering intent for these rammers.
A key is a small but critical fastening component used to lock a rotating part — such as a gear, pulley, or flywheel — securely to a shaft. It fits into matching slots called keyways cut into both the shaft and the mating component, preventing relative rotation between the two under load. When a key shears, wears, or goes missing, the shaft simply spins inside the component rather than driving it, causing a complete loss of power transmission and potential damage to surrounding components. Replacing a worn or damaged key promptly restores correct mechanical drive and protects the integrity of the shaft and hub surfaces.
