The Bomag 87280186 SPS Controlling is a genuine OEM component designed for Bomag BW 170 AD, BW 174 AD, BW 174 AC, and BW 184 AD tandem rollers, including AM and second-generation variants. Sourced directly from Bomag, this part carries the same specifications as the unit installed at the factory, ensuring a verified, exact-match replacement. It is compatible across the full BW 170 and BW 174 and BW 184 tandem roller range covered in Bomag's own parts catalog, including the BW 170 AD-2 AM, BW 174 AC-2, BW 174 AD-2 AM, and BW 184 AD-2.
Key Features
- Genuine OEM Control Accuracy — manufactured to Bomag's own electrical and signal specifications, ensuring the SPS controlling unit outputs correct readings and commands without adaptation
- Direct-Swap Installation — matches the original mounting configuration and connector interface of the factory-installed unit, allowing a straightforward swap with no wiring modifications
- Broad Tandem Roller Coverage — fits BW 170 AD, BW 174 AC, BW 174 AD, and BW 184 AD tandem rollers, including AC-2, AD-2, and AM variants, covering a wide range of the BW tandem roller lineup
- Compaction System Integrity — a correctly functioning SPS controlling unit keeps the compaction monitoring and steering pressure systems operating within spec, supporting consistent asphalt compaction performance
- Electrical Compliance — as a genuine OEM electrical control component, this part meets Bomag's circuit protection and signal-handling requirements, reducing the risk of system faults or sensor miscommunication
The SPS (Smooth Pad System or Steering/Pressure Sensor) controlling unit is an electronic control component that manages signal processing and system commands within the tandem roller's compaction or machine-control circuit. It acts as the communication hub between sensors and the machine's operating systems, ensuring that inputs from the drum, steering, or compaction monitoring systems are correctly interpreted and acted upon. When this component fails or degrades, the machine may display system faults, lose compaction feedback accuracy, or experience erratic control behavior — making prompt replacement with a verified OEM part critical to keeping the roller operating as intended.
