Key Features
- OEM Dimensional Accuracy — Manufactured to the precise 3/16 x 3/4 Woodruff key profile required for correct shaft-to-hub engagement on Wacker Neuson roller drivelines.
- Direct Slot-In Installation — Seats into the standard Woodruff keyway without modification, aligning shaft and hub components exactly as originally assembled.
- Broad Roller Compatibility — Fits RD12, RD16, RD12A, RD11, RD880V, and CB14B series rollers across multiple configurations, including tandem, foldable ROPS, and hydrostatic variants.
- Torque Transmission Integrity — A correctly sized Woodruff key maintains positive drive between rotating components; a worn or incorrectly sized key causes slippage, vibration, and accelerated wear to shaft and hub surfaces.
- Genuine Wacker Neuson OEM Part — Supplied as an authorized Wacker Neuson replacement, carrying part number 5002009108 for straightforward cross-referencing against your parts manual.
A Woodruff key is a small, semi-circular metal key that fits into a matching curved keyway cut into a shaft, locking a hub, pulley, or sprocket in rotational alignment with that shaft. It transmits torque between the two components and prevents the mating part from spinning independently under load. When a Woodruff key shears, deforms, or works loose — typically from shock loading or prolonged wear — the driven component loses its positive connection to the shaft, resulting in power loss, erratic machine behavior, or mechanical damage to the keyway itself. Replacing a failed or suspect key promptly with the correct OEM part protects the surrounding shaft and hub from the secondary damage that an ill-fitting key can cause.
