The Bomag 31791185 Sensor is a genuine OEM component designed for BW 170 AD, BW 174 AC, BW 174 AD, and related tandem roller variants. Sourced directly from Bomag, this sensor delivers the exact fit and specification your machine requires. Compatible across a broad range of BW 170 and BW 174 series tandem rollers — including AM, AC, AD, AP, and second-generation (-2) variants — this part ensures your machine's sensing system operates exactly as designed. When you need a verified, direct-replacement sensor, part number 31791185 is the correct choice for these Bomag tandem rollers.
Key Features
- Genuine OEM Signal Accuracy — manufactured to Bomag's original electrical and output specifications, ensuring the sensor reads and transmits data exactly as the machine's control system expects
- Direct-Replacement Fit — engineered to the same mounting configuration and connector profile as the original, installing into the machine without modification
- Broad BW 170 and BW 174 Coverage — fits BW 170 AD, BW 170 AD-2 AM, BW 174 AC, BW 174 AC-2, BW 174 AC-2 AM, BW 174 AC AM, BW 174 ACP-AM, BW 174 AD, BW 174 AD AM, BW 174 AD-2, BW 174 AD-2 AM, BW 174 AP, and BW 174 AP-AM tandem rollers
- Protects Machine Control Systems — a faulty sensor can trigger false readings or suppress critical feedback, leading to incorrect compaction output or system faults; replacing it promptly restores accurate machine response
- Electrical Integrity — as an OEM part, this sensor meets the original resistance, voltage, and signal-range tolerances that Bomag's onboard systems are calibrated to work with
A sensor on a tandem roller monitors a specific operating condition — such as drum rotation, temperature, pressure, or position — and feeds that data to the machine's control system. When the sensor functions correctly, the roller's electronic systems can regulate compaction force, detect anomalies, and protect critical components. A worn or failed sensor can produce erratic readings, trigger warning codes, or cause the machine to operate outside its intended parameters, reducing compaction quality and potentially masking mechanical issues before they become more serious.
