Wacker Neuson 5000163767 Lock Washer 1/4 Split

The Wacker Neuson is a genuine OEM Lock Washer 1/4 Split designed for the BFS 2020AS and BFS 1318AS walk-behind floor saws. As a direct Wacker Neuson OEM component, the is manufactured to the exact specification of the original part, ensuring proper seating and holding force at its fastener location. This washer is the correct choice for restoring a secure, vibration-resistant connection during scheduled maintenance or repair on either saw model.

Key Features

• OEM-Grade Spring Tension: — Manufactured to the original split-ring profile and hardness spec, delivering the correct clamp load to resist loosening under saw vibration.
• Drop-In Installation: — Sized to 1/4-inch fastener diameter, this washer seats directly onto the existing hardware without any modification to the surrounding assembly.
• Confirmed Fitment: — Verified for the BFS 2020AS and BFS 1318AS self-propelled walk-behind floor saws.
• Vibration Resistance Where It Counts: — Floor saws generate sustained cutting vibration; a worn or missing lock washer allows fasteners to back out, leading to misalignment or component loosening during operation.
• Genuine Wacker Neuson Part: — Sourced directly from Wacker Neuson, so the part number, material, and geometry match the original exactly — critical for a small fastener component where substitutions can compromise clamping integrity.

A split lock washer works by biting into the mating surfaces on both sides of a fastener joint as the nut or bolt is tightened, creating a spring-loaded resistance that prevents the fastener from rotating loose under vibration or cyclical loads. In a walk-behind floor saw, where the blade assembly and drivetrain generate continuous vibration during cutting, maintaining fastener torque is essential to keeping critical components properly secured. A cracked, flattened, or missing lock washer allows fasteners to gradually work loose, which can lead to component shift, increased wear on adjoining parts, or unsafe operating conditions.
