The Bomag 05817113 Magneto is a genuine OEM ignition component designed for the BW 90 AD tandem roller. Sourced directly from Bomag, this magneto meets the exact output and timing specifications required by the original engine, ensuring reliable ignition performance on every start. As an authentic OEM part, it replaces the original unit with no guesswork — part number 05817113 is your direct reference for confirmed compatibility with the BW 90 AD.
Key Features
- Correct Ignition Output — genuine OEM construction delivers the precise voltage and spark timing the BW 90 AD engine requires, maintaining proper combustion at every operating speed
- Authentic Bomag OEM Part — manufactured to the same specification as the unit installed at the factory, with no deviation in electrical output or mounting configuration
- Direct Replacement Fit — mounts to the existing ignition system on the BW 90 AD tandem roller using the original hardware and connection points
- Confirmed Fitment — part number 05817113 is verified for the Bomag BW 90 AD tandem roller
- Engine Protection Through Proper Spark — a worn or failing magneto causes hard starts, misfires, and power loss; replacing it restores clean, consistent ignition and protects the engine from running rough under load
- Ignition System Safety — a correctly functioning magneto maintains stable engine control; a degraded unit can cause unpredictable engine behavior on live compaction sites
The magneto is a self-contained ignition generator that produces the high-voltage spark needed to fire the engine without relying on a battery or external power source. It uses a rotating magnetic field to generate and time the electrical pulse sent to the spark plug, making it essential to engine starting and smooth operation. When the magneto wears or fails, symptoms include difficulty starting, engine misfires, and loss of power — all of which bring compaction work to a halt until the unit is replaced.
