The Wacker Neuson is a genuine OEM Woodruff Key 3/16 X 3/4, #9 designed for the WB16A series Power Buggy. Sourced directly from Wacker Neuson, this key is manufactured to the exact dimensions required to maintain correct shaft-to-hub engagement on your machine. It fits the full WB16A Power Buggy lineup, including WB16A, WB16AF, WB16AS, WB16AD, WB16AE, WB16ADF, WB16ADE, WB16ADS, WB16AEF, WB16AES, WB16ADEF, WB16ADES, WB16ADFS, WB16AEFS, and WB16ADEFS models. When this small but critical component wears or shears, replacing it promptly with the correct OEM part keeps drivetrain power transfer on track.
Key Features
- OEM-Specified Dimensions — Manufactured to the exact 3/16 x 3/4 inch profile required for proper shaft-to-hub seating on WB16A Power Buggy drivetrains.
- Drop-In Shaft Fit — Seats directly into the existing keyway without machining or modification, restoring the shaft-hub connection as originally assembled.
- Broad WB16A Series Coverage — A single part number covers the complete WB16A Power Buggy family across gasoline, electric, and dual-engine configurations.
- Restored Torque Transfer — A correctly seated Woodruff Key locks the hub to the shaft, ensuring full drivetrain torque is delivered without slipping or lost motion.
- Genuine Wacker Neuson OEM Part — Backed by Wacker Neuson as a factory-original component, matched to the material grade and geometry specified at the time of manufacture.
A Woodruff key is a small semi-circular metal key that sits in a matching keyway cut into a shaft and hub, locking them together so they rotate as a single unit. On the WB16A Power Buggy, it plays a direct role in transferring engine or motor torque to the driven component — when it shears or wears, the hub spins free of the shaft and drive is lost entirely. Because Woodruff keys are precision-dimensioned components, using a correctly sized replacement like the 5000116146 ensures the keyway seats without play and restores full power transmission.
