The Wacker Neuson Woodruff Key is a genuine OEM Woodruff Key designed for a broad range of Wacker Neuson equipment, including the RD12-90 Tandem Roller, CRT36-25 Ride-on Trowel, and BFS series floor saws. As a direct factory replacement, this part is sourced to the same specification as the original component installed at the time of manufacture. It fits across multiple machine configurations within these product families, making it a reliable go-to when servicing your equipment. Always confirm your model and serial number against the fitment list before ordering.
Key Features
- Genuine OEM Metallurgy — Manufactured to Wacker Neuson's original material hardness and dimensional spec, ensuring the key seats correctly in the shaft keyway without deformation under load.
- Drop-In Shaft Replacement — Matches the original half-moon profile exactly, dropping straight into the existing keyway slot with no filing or fitting required.
- Broad Equipment Compatibility — Fits RD12-90 double drum rollers, CRT36-25 ride-on trowels, and the full BFS and BFSX floor saw lineup, covering both petrol and diesel variants.
- Torque Transmission Integrity — A correctly seated Woodruff Key locks the gear or pulley to the shaft and transfers rotational force cleanly; a worn or sheared key causes slippage, erratic power delivery, and accelerated component wear.
- Part Number Verified — Listed under OEM part number 5000205592, matching Wacker Neuson's official parts documentation for the models shown in the fitment list.
A Woodruff Key is a small, semi-circular metal key that fits into a matching slot machined into a rotating shaft, locking a gear, sprocket, or pulley in precise rotational alignment with that shaft. It is responsible for transmitting torque between the shaft and the mounted component — without it, those parts spin independently and the machine loses drive or power transfer entirely. When a Woodruff Key shears or wears, the symptom is usually sudden loss of function in the affected drive system, and continued operation can cause secondary damage to the shaft or hub.
