The Bomag 05720658 Magneto is a genuine OEM ignition component designed for the BMP 851 trench compactor. Sourced directly from Bomag, this magneto matches the original specification exactly, ensuring correct spark timing and reliable engine starting performance. If your BMP 851 is experiencing hard starts, misfires, or ignition failure, this is the correct OEM replacement to restore full operation.
Key Features
- OEM Ignition Precision — genuine Bomag manufacture means correct spark output, timing curve, and coil resistance for the BMP 851 engine — no guesswork on ignition specs
- Direct-Fit Replacement — engineered to swap in place of the original unit with matching mounting points and electrical connections for a clean installation
- Confirmed Fitment — verified for the BMP 851 trench compactor, so you can order with confidence knowing part number 05720658 is the right component for your machine
- Consistent Engine Starting — a correctly functioning magneto delivers a strong, timed spark every cycle, keeping the engine starting cleanly and running at full compaction power
- Ignition Safety Integrity — a failing magneto can cause unpredictable engine behavior; replacing it with the genuine OEM part restores safe, predictable engine response on the compactor
A magneto is a self-contained ignition generator that produces the high-voltage electrical spark needed to fire the engine's combustion cycle — without relying on a battery or external power source. It uses rotating magnets to generate current through a coil, which is then discharged across the spark plug at precisely the right moment in the engine's stroke. When a magneto weakens or fails, the engine may become difficult to start, run erratically, lose power, or stop altogether — directly impacting the compaction output of the machine.
