The Bomag 05741435 Generator is a genuine OEM replacement built for Bomag tandem rollers across the BW 100, BW 120, BW 125, and BW 131 series. Sourced directly from Bomag, this generator meets the same output specifications as the original unit installed at the factory. It is confirmed to fit generation -4 and -5 variants including the BW 100 AD-4, BW 100 AC-4, BW 120 AD-4, BW 120 AC-4, BW 125 AD-4, BW 125 AC-4, BW 100 AD-5, BW 100 AC-5, BW 100 SL-5, BW 115 AC-5, BW 120 AD-5, BW 120 AC-5, BW 120 SL-5, BW 120 SLC-5, BW 120 AD-5 CC, BW 131 AD-5, and BW 131 ACW-5 tandem rollers, making it a versatile stock item for fleets running mixed generations of Bomag equipment.
Key Features
- OEM-Matched Electrical Output — genuine Bomag part number 05741435 is manufactured to the same voltage and amperage spec as the original, ensuring the roller's electrical systems receive consistent, stable power
- Direct-Fit Replacement — engineered to the original mounting configuration and connector layout, so this generator installs into the machine's existing bracket and wiring harness without adaptation
- Broad Generation Coverage — fits BW 100, BW 120, BW 125, and BW 131 tandem rollers across both -4 and -5 generation builds, including SL, SLC, AC, AD, ACW, and CC variants
- Protects Onboard Systems — a properly functioning generator keeps batteries charged and powers compaction control electronics; a failing unit can cause erratic instrument readings, battery drain, and unexpected shutdowns mid-operation
- Electrical Safety Assurance — as an OEM component, this generator is built to the correct grounding and insulation standards for Bomag tandem roller electrical architectures, reducing the risk of shorts or voltage irregularities
The generator on a tandem roller is responsible for converting mechanical engine power into electrical energy to charge the battery and supply the machine's onboard systems — including lights, compaction measurement electronics, and control panels. When the generator begins to fail, operators typically notice dimming displays, recurring battery warnings, or the machine losing power to auxiliary functions while running. Replacing a worn generator with a correct OEM unit restores stable electrical output and keeps the roller's full range of compaction and monitoring functions operating as intended.
