The Wacker Neuson is a genuine OEM Magneto Armature with Adjustable Tube designed for the BS50-2, BS60-2, BS70-2, BS500, BS600, BS700, and BS650 two-cycle vibratory rammer series, as well as BH 22, BH 23, BH 24, BH 40, BH 55, BH 65, and related gasoline breaker models. As a factory-original component, the is manufactured to the exact tolerances and output specifications required by Wacker Neuson for correct ignition timing and spark generation. This part covers an exceptionally wide range of BS-series rammers — including standard, variable-speed, high-altitude, and EU-market variants — along with the full BH-series gasoline breaker lineup, making it one of the most broadly compatible ignition components in the Wacker Neuson two-cycle engine family. Confirm your model number before ordering to ensure this is the correct armature for your specific configuration.
Key Features
- Genuine OEM Ignition Output Accuracy — Sourced directly from Wacker Neuson, this armature is built to deliver the precise magnetic field strength and spark timing required by two-cycle engines in rammer and gasoline breaker applications — no guesswork on ignition output.
- Adjustable Tube Included — The integrated adjustable tube allows correct air-gap setting during installation, ensuring the armature is positioned accurately relative to the flywheel for consistent spark performance from the first start.
- Broad BS-Series Rammer Compatibility — Fits BS50-2, BS60-2, BS70-2, BS500, BS600, BS700, BS650, and BS500S/BS600S rammers, covering standard, variable-speed, high-altitude, and multiple shoe-size configurations across both US and EU markets.
- BH-Series Gasoline Breaker Coverage — Also compatible with BH 22, BH 23, BH 24, BH 40, BH 55, BH 65, and Low Vibration variants, extending the usefulness of this single part number across Wacker Neuson's gasoline demolition tool lineup.
- Restores Reliable Ignition — A worn or damaged magneto armature causes hard starting, misfiring, or complete failure to run. Replacing it with a correctly spec'd OEM unit restores clean, consistent ignition so the machine delivers full compaction or breaking force on every stroke.
- Fuel System Safety Alignment — Correct armature timing is critical in two-cycle engines; an improperly timed or failing armature can cause backfiring or uncontrolled combustion events. Using the genuine OEM part maintains the engine's designed ignition behavior.
The magneto armature is the core of the ignition system in two-cycle gasoline engines. As the flywheel rotates past the armature's magnetic poles, it generates the electrical pulse that fires the spark plug at precisely the right moment in the combustion cycle — giving the engine its power stroke. When the armature weakens, corrodes, or its air gap drifts out of specification, spark energy drops off and the engine becomes difficult to start, runs erratically, or stops firing altogether. On rammers and gasoline breakers, where consistent combustion energy directly drives the impact mechanism, a degraded armature means reduced compaction force or breaking output — and eventually a machine that won't run at all. Replacing the armature with the correct OEM part, and setting the air gap properly using the included adjustable tube, fully restores ignition integrity.
