The Bomag 55003021 Buzzer is a genuine OEM component designed for BW 172 D-2, BW 142 D-2, and BW 212 D-2 single drum rollers. Sourced directly from Bomag, this buzzer matches the original part in fit, function, and electrical specification — ensuring seamless installation with no guesswork. As a genuine OEM part, it is built to the same standards as the component that left the factory, giving operators confidence that their machine's alert and warning system will respond correctly in the field.
Key Features
- Correct Electrical Specification — matched to the original output rating and circuit requirements of the BW-series single drum roller warning system, ensuring the buzzer triggers accurately under the correct conditions
- Direct OEM Replacement — connects to the existing wiring harness without adaptation, replacing the original unit on BW 172 D-2, BW 142 D-2, and BW 212 D-2 single drum rollers
- Genuine Bomag Part — sourced from Bomag's authorized supply chain, carrying part number 55003021 for straightforward verification against your machine's parts manual
- Restored Warning System Function — a failed or silent buzzer leaves operators without critical audible alerts; this replacement restores full audible signaling to keep warning systems operational
- Electrical Safety Compliance — audible warning devices are a key element of machine safety; using a correctly rated OEM buzzer ensures the warning system meets the roller's original design intent
The buzzer is an audible signaling device integrated into the machine's warning and alert system. It produces a distinct sound to notify the operator of specific conditions — such as a fault state, reverse travel engagement, or system warning — depending on how it is wired within the machine's circuit. When the buzzer fails or becomes non-functional, operators lose an important layer of audible feedback, which can delay response to faults or create unsafe working conditions. Replacing a failed unit with the correct OEM part restores the system to its intended operation.
