The Wacker Neuson Control Shaft Weldment is a genuine OEM component designed for the BFS16, BFS18, BFS20, and BFSX series floor saws. Sourced directly from Wacker Neuson, this part meets the same specifications as the original component installed at the factory, ensuring a direct, like-for-like swap. Compatibility spans a wide range of BFS and BFSX configurations — including diesel and standard variants — making a go-to replacement for fleet operators and service technicians working across multiple saw models.
Key Features
- Genuine OEM Weld Integrity — Manufactured to Wacker Neuson's original weld and dimensional tolerances, so the shaft assembly maintains the precise geometry needed for correct steering and depth-control linkage engagement.
- Direct Bolt-In Replacement — Matches original mounting points and shaft dimensions, allowing installation without reworking brackets or linkage connections on BFS and BFSX floor saws.
- Broad BFS Series Coverage — Fits BFS16, BFS18, BFS18D, BFS20, BFS20D, BFSX16, BFSX18, BFSX18D, BFSX20, and BFSX20D models, covering both standard and diesel-powered variants in the floor saw lineup.
- Restored Operator Control — A worn or damaged control shaft weldment leads to sloppy blade-depth adjustment and imprecise directional control; replacing it restores sharp, predictable machine response on every cut.
- Verified Part Number — Ordered by part number 5000402239, this is the correct OEM replacement pulled from Wacker Neuson's parts catalog — no guesswork on fitment.
The control shaft weldment is a fabricated steel assembly that connects the operator controls to the blade-depth and directional mechanisms on a walk-behind floor saw. It transmits input from the operator's handle adjustments through the machine's linkage system, allowing accurate control of cutting depth and blade alignment during concrete or asphalt cutting operations. When this weldment bends, cracks, or wears at its pivot points, the operator loses precise control over the blade — resulting in uneven cuts, increased operator effort, and potential damage to the saw's cutting system.
