The Wacker Neuson Ignition Coil Complete is a genuine OEM component designed for a wide range of Wacker Neuson gasoline-powered equipment, including the BFS940 and BFS 940A floor saws, BPU 3050A and BPU 4045A reversible vibratory plate compactors, GV5000A and GV5003A portable generators, PT3A trash pump, and BT48A. Sourced directly from Wacker Neuson, this ignition coil carries the same part number — — as the original factory-installed unit, so you can install with confidence. It delivers the precise spark timing and output voltage your engine demands, helping maintain clean starts and consistent combustion across all supported models. Whether you're servicing a floor saw on a busy job site or restoring a generator to full working condition, the is the correct OEM replacement.
Key Features
- Correct Spark Output: — Engineered to deliver the exact ignition voltage required by the small gasoline engines used across the BFS, BPU, GV, PT, and BT model families.
- Genuine OEM Part: — Manufactured to Wacker Neuson's original specification, ensuring coil windings, air gap tolerance, and connector fit match the original unit precisely.
- Drop-In Installation: — Mounts to the same bolt pattern and connects to the same kill-switch wire as the original coil — no adaptation or modification needed for listed models.
- Broad Cross-Family Fitment: — A single part number covers floor saws (BFS 914A, BFS 935AB, BFS940, BFS 940A), reversible plate compactors (BPU 3050A, BPU 3750Ats, BPU 4045A), portable generators (GV5000A, GV5003A), PT3A trash pump, and BT48A — confirm your model and machine number before ordering.
- Fuel System Safety Relevance: — A correctly functioning ignition coil prevents misfires and unburned fuel from accumulating in the combustion chamber, reducing the risk of backfire or hard-start conditions that can stress engine components.
- Supports Long Engine Life: — A worn or failed coil causes weak or absent spark, leading to hard starting, rough running, and accelerated wear on the recoil starter and carburetor — replacing it at the first sign of ignition trouble protects the rest of the engine.
The ignition coil generates the high-voltage electrical pulse that fires the spark plug at precisely the right moment in the engine's combustion cycle. It works by transforming the low-voltage current from the engine's flywheel magnets into the high-voltage charge needed to jump the spark plug gap and ignite the air-fuel mixture. When the coil weakens or fails, the engine may crank but refuse to start, run erratically, or cut out under load — symptoms that are often mistaken for carburetor or fuel delivery problems. Replacing a faulty coil with the correct OEM unit restores reliable ignition and gets the engine running cleanly again.
