The Bomag 08821020 Generator is a genuine OEM component designed for the BW 177 D-5 and BW 145 D-5 single drum rollers. Sourced directly from Bomag, this generator delivers an exact match to the original unit — correct mounting configuration, output rating, and electrical connections included. This generator fits both the BW 177 D-5 and BW 145 D-5, giving operators a straightforward, stock replacement with no guesswork on compatibility.
Key Features
- Genuine OEM Electrical Output — matched to the original voltage and amperage spec, ensuring the machine's electrical system receives consistent, stable power generation
- Direct Replacement Fit — replaces the original generator on BW 177 D-5 and BW 145 D-5 single drum rollers with the same bolt pattern and wiring interface as the factory unit
- Confirmed Fitment — verified for Bomag BW 177 D-5 and BW 145 D-5 single drum rollers, so you order with confidence
- Protects Onboard Systems — a properly functioning generator keeps batteries charged and powers critical machine controls; a failed unit can cause electrical faults, starting failures, and compaction downtime
- Electrical Safety Compliance — as an OEM-spec electrical component, this generator meets the original design tolerances that protect the machine's wiring harness and control systems from overload
The generator on a BOMAG single drum roller is responsible for producing the electrical current that charges the battery and powers the machine's electrical loads while the engine is running. Without a properly functioning generator, the battery drains under normal operation, leading to starting failures, loss of control-system power, and an inability to run the machine safely. Replacing a worn or failed generator with a genuine OEM unit like part number 08821020 restores correct electrical output and protects the downstream components that depend on a steady, regulated supply.
