Key Features
- OEM Output Specification — genuine Bomag alternator matched to the correct voltage and amperage output required by BW 177-series single drum rollers, eliminating the risk of undercharging or electrical overload
- Direct-Mount Fitment — mounts to the original bracket locations and connects to the factory wiring harness without modification, allowing straightforward installation on covered models
- Broad BW 177 Series Coverage — fits BW 177 D-40, BW 177 DH-40, BW 177 PDH-40, BW 177 D-50, BW 177 DH-50, and BW 177 PDH-50 single drum rollers, covering both the -40 and -50 generations
- Charging System Integrity — a properly functioning alternator sustains battery charge and powers onboard electronics; a failing unit leads to battery drain, warning faults, and eventual machine shutdown
- Electrical Safety Assurance — as a critical component in the machine's electrical circuit, an OEM-specified alternator protects sensitive control systems from voltage irregularities that can cause component damage or unsafe operating conditions
The alternator is the primary source of electrical power while the engine is running, continuously charging the battery and supplying current to the machine's electrical systems — lights, controls, and onboard electronics. On heavy single drum rollers like the BW 177 series, a healthy alternator is essential for uninterrupted operation through long compaction shifts. When an alternator begins to fail, output voltage drops, the battery can no longer sustain a charge, and the machine may experience erratic system behavior or fail to start — making timely replacement with a correctly rated OEM unit critical to keeping the roller productive.
