The Wacker Neuson Woodruff Key 3/16 X 3/4 is a genuine OEM component designed for the BFS 2020AS and BFS 1318AS walk-behind floor saws. Sourced directly from Wacker Neuson, this key is manufactured to the exact dimensions and material grade required by the original equipment, ensuring a correct, secure fit in the keyway without rework or modification. It is the right part to specify whenever a blade shaft or drive shaft key shows signs of shear, wear, or deformation. Confirm your model number against the BFS 2020AS and BFS 1318AS fitment list before ordering to ensure compatibility.
Key Features
- Exact OEM Dimensions — Cut to the precise 3/16 x 3/4 Woodruff profile specified by Wacker Neuson, so the key seats fully in the keyway without slop or binding.
- Genuine Wacker Neuson Part — Supplied as authentic OEM stock, meaning the metallurgy and hardness match the original key that came with the machine.
- Direct Drop-In Replacement — Designed to slot directly into the existing keyway on the BFS 2020AS and BFS 1318AS floor saw shaft assemblies with no filing or fitting required.
- Protects Drive Components — A correctly sized key transmits torque evenly between shaft and hub; an undersized or worn key allows fretting that damages the shaft and pulley bore over time.
- Verified BFS Series Fitment — Confirmed for the BFS 2020AS and BFS 1318AS self-propelled walk-behind floor saws — cross-reference part number 5000163739 against your machine's parts diagram before ordering.
A Woodruff key is a small, semi-circular or rectangular drive key that fits into matching keyways machined into a shaft and a mating hub, pulley, or sprocket. Its job is to lock these two components together rotationally so that torque is transferred without slippage. On a floor saw like the BFS series, the key plays a critical role in keeping blade drive components positively engaged with the shaft. When a Woodruff key shears or wears, the hub or pulley can spin free on the shaft, causing loss of drive, accelerated wear to the keyway surfaces, and potential damage to more expensive components further up the drivetrain.
