The Bomag 58170119 Potentiometer is a genuine OEM component designed for BW 177 DH-3 and BW 177 PDH-3 single drum rollers. As a direct OEM replacement, this potentiometer meets Bomag's original design specifications, ensuring the signal output and positional feedback your machine's control system depends on remain accurate and consistent. This part is compatible across BW 177 DH-3, BW 177 DH-3 USA, BW 177 PDH-3, and BW 177 PDH-3 USA variants, making it the correct choice for operators and technicians servicing this roller family.
Key Features
- OEM-Calibrated Signal Output — manufactured to Bomag's original resistance and output specifications, so the control system receives the precise positional data it was engineered around
- Direct Drop-In Replacement — designed to match the original mounting configuration and electrical connector of the BW 177 series, allowing straightforward installation without modification
- Broad BW 177 Series Coverage — fits BW 177 DH-3, BW 177 DH-3 USA, BW 177 PDH-3, and BW 177 PDH-3 USA single drum rollers, covering both standard and USA-spec machines
- Control System Integrity — a worn or drifting potentiometer causes erratic control response and inaccurate feedback; replacing it with a genuine OEM part restores consistent, predictable machine behavior
- Electrical Safety Assurance — as a genuine OEM electrical component, this potentiometer meets the original insulation and tolerance standards, reducing the risk of signal errors that could affect operator control inputs
A potentiometer is a variable resistor that translates a physical position — such as a lever, throttle, or control arm — into an electrical signal the machine's control system can read and act on. In a single drum roller like the BW 177 series, the potentiometer plays a critical role in communicating operator inputs to the drive and vibration control electronics. When the potentiometer wears out or fails, the machine may respond erratically, display fault codes, or lose smooth control response, making prompt replacement essential for safe and efficient compaction work.
