The Bomag 05716778 Generator is a genuine OEM replacement built for a wide range of Bomag tandem rollers and single drum rollers, including BW 100, BW 120, BW 124, BW 125, BW 135, BW 138, and BW 145 series machines, as well as C 815 C and C 825 C single drum rollers. Sourced directly from Bomag, this generator delivers an exact match to the original component it replaces, ensuring correct electrical output and system compatibility. Whether you are servicing a BW 145 DH-3 single drum roller or a BW 120 AD-3 tandem roller, this genuine OEM part is engineered to the same specification as the unit that came on the machine.
Key Features
- Genuine OEM Electrical Output — manufactured to Bomag's original voltage and current specifications, ensuring the generator meets the charging demands of the machine's electrical system
- Direct-Fit Replacement — matches the original mounting configuration and connector interface, allowing straightforward installation without adaptation
- Broad Roller Coverage — fits BW 100, BW 120, BW 124, BW 125, BW 135, BW 138, and BW 145 series tandem rollers and single drum rollers, including C 815 C and C 825 C models
- Sustained Charging Performance — a properly functioning generator keeps the battery charged and all onboard electrical systems operating correctly; a failing unit can cause battery drain, warning light activation, and unplanned stoppages
- Authentic Bomag Part — supplied under part number 05716778 with full OEM traceability, giving you confidence that the component matches the original design intent
The generator is responsible for producing electrical power while the engine is running, converting mechanical energy from the engine into the current needed to charge the battery and supply the machine's electrical loads. On compaction equipment like Bomag tandem and single drum rollers, a healthy generator is essential for keeping ignition, lighting, instrumentation, and vibration-control electronics powered throughout the workday. When the generator begins to fail — through worn brushes, a faulty rectifier, or bearing degradation — the battery can no longer maintain its charge, leading to difficult starting, erratic instrument readings, and eventual machine shutdown.
