The Wacker Neuson Magneto Flywheel is a genuine OEM component designed for the BFS 1345AS, BFS 1345ALS, BFS 1350AS, and BFS 1350ALS gasoline floor saw series. As a direct OEM replacement, this part is manufactured to Wacker Neuson's exact design specifications, ensuring a precise match to the original component it replaces. Sourced directly through authorized Wacker Neuson parts channels, the is the correct, verified part for these BFS-series slab saws. If your floor saw is experiencing ignition issues or charging irregularities, replacing the magneto flywheel with this genuine OEM part restores the ignition system to its original operating condition.
Key Features
- Genuine OEM Ignition Integrity — Manufactured to original Wacker Neuson specifications, ensuring correct magnetic pole alignment and output consistency critical to reliable ignition timing on gasoline floor saws.
- Direct Bolt-On Fitment — Engineered to mount directly to the crankshaft taper of BFS-series engines, matching the original flywheel's bore, keyway, and fastener pattern without modification.
- BFS-Series Compatibility — Confirmed fit for the BFS 1345AS, BFS 1345ALS, BFS 1350AS, and BFS 1350ALS gasoline floor saws with 450mm and 500mm drive configurations.
- Consistent Spark Delivery — A correctly functioning magneto flywheel maintains steady ignition spark across the full RPM range, keeping the saw's engine running smoothly under the high-load demands of concrete and asphalt cutting.
- Ignition System Safety — A worn or damaged magneto flywheel can cause erratic spark timing or total ignition failure; replacing it with the correct OEM part restores predictable engine behavior and safe saw operation.
The magneto flywheel serves a dual purpose in a gasoline-powered floor saw: it acts as a rotating mass that smooths engine output, and its embedded permanent magnets generate the electrical charge that powers the ignition system. As the flywheel spins past the ignition module, the magnets induce a voltage pulse that fires the spark plug at the correct moment in the combustion cycle. When the flywheel is cracked, has damaged magnets, or has a worn keyway, ignition timing becomes inconsistent or the engine may fail to start altogether — both of which bring cutting operations to a halt.
