The Wacker Neuson Flywheel Complete is a genuine OEM Flywheel Complete designed for a wide range of Wacker Neuson floor saws, plate compactors, and portable generators, including the BFS1345, BFS1350, BFS1318, GV7000A, GV7003A, BPU5545A, BPU5260Ah, BPU6275Ah, and RD7Af HRC series. Sourced directly from Wacker Neuson, this is the same assembly installed at the factory — no guesswork, no adaptation, and no compromise on fitment accuracy. Compatibility spans multiple production variants across the BFS and BPU machine lines, making a high-demand service part for dealers and contractors running Wacker Neuson equipment.
Key Features
- Genuine OEM Ignition Timing Integrity — Manufactured to Wacker Neuson's original flywheel mass and magnet specifications, preserving correct ignition timing and charging output across the supported engine platforms.
- Drop-In Assembly Fit — Supplied as a complete flywheel assembly with all integrated components, mounting directly to the crankshaft taper using the original hardware — no machining or adaptation needed.
- Broad Model Coverage — A single part number covers the BFS1318, BFS1345, and BFS1350 floor saw families, GV7000A and GV7003A portable generators, BPU5545A, BPU5260Ah, and BPU6275Ah plate compactors, and RD7Af HRC reversible plate series.
- Restored Engine Starting Performance — A worn or cracked flywheel causes hard starting, misfires, and erratic engine speed; replacing it with a correctly balanced OEM unit restores smooth cranking and consistent power delivery.
- Electrical System Reliability — The integrated magneto magnets on this flywheel drive the ignition coil and charging circuit; genuine construction maintains correct field strength to prevent voltage irregularities that can damage connected components.
The flywheel is a precision-balanced rotating mass bolted to the engine crankshaft. It stores rotational energy between power strokes to keep the engine running smoothly, and its embedded permanent magnets generate the magnetic field that drives the ignition system and, in generator applications, contributes to the charging circuit. A flywheel that is cracked, out of balance, or has degraded magnets will cause rough running, ignition failure, and in some cases complete inability to start. Replacing a failed flywheel with the correct OEM assembly restores the engine's mechanical balance and ensures the ignition system receives the signal it needs to fire reliably under load.
