The Wacker Neuson is a genuine OEM Square Key 1/4 X 1-3/4 designed for the BFS 2020AS and BFS 1318AS walk-behind floor saws. As a factory-sourced component, it meets the exact dimensional and material specifications Wacker Neuson requires for correct drive train engagement in these machines. This key indexes the blade shaft or drive component precisely, ensuring torque is transferred cleanly without slipping or misalignment. Verified fitment covers both the BFS 2020AS and the self-propelled BFS 1318AS floor saw platforms.
Key Features
- OEM Dimensional Accuracy — Cut to exact 1/4 x 1-3/4 specification, ensuring full keyway contact and positive torque lock without shimming or filing.
- Direct Drop-In Replacement — Seats directly into the existing keyway on BFS 2020AS and BFS 1318AS saws with no secondary machining needed.
- Confirmed Fitment — Verified for both the BFS 2020AS and the self-propelled walk-behind BFS 1318AS floor saw models.
- Drive Integrity Maintained — A worn or undersized key causes drive slippage and accelerated keyway wear on the shaft; a correctly sized OEM key prevents that damage from progressing.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, carrying part number 5000163740 for straightforward parts verification and reordering.
A square key is a small but critical power-transmission component seated between a shaft and a hub — such as a drive pulley or blade arbor — to lock them together rotationally so that torque passes from one to the other without slipping. When this key wears, shears, or goes missing, the driven component can spin freely on the shaft, causing loss of blade drive or belt-drive function and rapid damage to the keyway itself. Replacing a failed key promptly with a correctly sized OEM piece like the Wacker Neuson 5000163740 restores full drive engagement and protects the shaft and hub from the secondary wear that a loose or undersized key accelerates.
