The Wacker Neuson Throttle Assembly is a genuine OEM component designed for BFS16, BFS18, BFS20, and BFSX series floor saws. As a factory-sourced part, it meets the exact engineering specifications Wacker Neuson built into these machines, ensuring the throttle responds correctly and consistently under cutting load. This assembly covers a wide range of BFS and BFSX models, including D and A variants, making it the right choice whether you are servicing a standard or diesel-configured saw. Confirm your model number before ordering to ensure a direct match.
Key Features
- OEM Throttle Calibration — Factory-sourced construction ensures the throttle cable travel, tension, and engagement points match Wacker Neuson's original design for consistent engine response.
- Direct-Fit Assembly — Supplied as a complete throttle assembly, connecting directly to the existing mounting points and cable routing without additional fabrication.
- Broad BFS and BFSX Compatibility — Fits BFS16, BFS18, BFS18D, BFS20, BFS20D, BFSX16, BFSX18, BFSX18D, BFSX18A, BFSX20, BFSX20D, and BFSX20A floor saw models.
- Restored Engine Control — A correctly functioning throttle assembly gives the operator precise RPM control during cutting passes, protecting the blade and the engine from unintended load spikes.
- Fuel System Safety — Throttle integrity directly affects engine speed management; using a genuine OEM replacement maintains safe, controlled operation and prevents unintended runaway throttle conditions.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, part number 5000403514 carries the same quality assurance as the original production component.
The throttle assembly controls the flow of fuel and air into the engine by managing the throttle valve position in response to operator input. On a floor saw, precise throttle control is critical — it allows the operator to regulate blade speed and cutting depth response during demanding concrete or asphalt cuts. When a throttle assembly wears out or fails, symptoms typically include erratic engine speed, loss of power response, or an engine that will not hold a steady RPM, all of which compromise cut quality and safe machine operation.
