The Wacker Neuson Magneto Assembly is a genuine OEM ignition component designed for the BH series gasoline-powered breakers, including the BH 23 RS, BH 22 RS, BH 24 Low Vib RS, BH 55RW RS, and BH 40 RS models. As a direct OEM replacement, the is manufactured to the same specifications as the original unit, ensuring correct air gap tolerance, coil output, and trigger timing straight out of the box. This part covers a wide range of BH series breakers, making it a reliable stock item for service shops and rental fleets that run multiple Wacker Neuson gasoline breaker models. Verify your machine number against the fitment list before ordering to confirm compatibility with your specific unit.
Key Features
- Correct Ignition Output: — Wound and calibrated to OEM coil specification, delivering the precise spark energy required for reliable combustion in BH series gasoline breakers.
- Direct OEM Drop-In Replacement: — Mounts to the existing ignition plate bracket using the original fastener pattern, with no re-gapping tools or adapter hardware needed beyond standard service procedure.
- Broad BH Series Fitment: — Compatible with the BH 23 RS, BH 22 RS, BH 24 Low Vib RS, BH 55RW RS, and BH 40 RS gasoline breakers across multiple machine configurations.
- Restores Cold and Hot Start Performance: — A degraded magneto is one of the leading causes of hard starting, misfires, and intermittent shutdowns in gasoline breakers; replacing it with 5000126090 restores consistent ignition across the full operating temperature range.
- Genuine Wacker Neuson OEM Part: — Supplied as an authorized OEM component, carrying the same part number referenced in Wacker Neuson service documentation for these BH series models.
The magneto assembly is the self-contained ignition generator in a gasoline-powered breaker. It uses permanent magnets rotating past a wound coil to produce the high-voltage spark that fires the engine without relying on an external battery or charging system. When the magneto wears or its coil breaks down internally, the engine will typically exhibit weak spark, hard starting, random misfires under load, or a complete failure to run. Replacing a faulty magneto restores the ignition system to full output and brings the breaker back to reliable working condition.
