The Bomag 05878172 Magnetic Coil is a genuine OEM Magnetic Coil designed for BW 161 AD-4, BW 161 ADH-4, and BW 161 AD-4 EU-Flex tandem rollers. Sourced directly from Bomag, this coil meets the original electrical and mechanical specifications for these machines. Confirmed fitment across the BW 161 AD-4 series means this component installs correctly without guesswork or adaptation.
Key Features
- Genuine OEM Electrical Integrity — wound and rated to the exact resistance and magnetic output spec required for proper solenoid actuation on BW 161 series tandem rollers
- Direct Drop-In Replacement — engineered to the original connector and mounting geometry, so this coil seats and connects the same way as the factory-installed unit
- Confirmed BW 161 AD-4 Series Coverage — fits the BW 161 AD-4, BW 161 ADH-4, and BW 161 AD-4 EU-Flex tandem rollers as listed in Bomag's OEM catalog
- Consistent Solenoid Actuation — a correctly functioning magnetic coil delivers steady electromagnetic force to engage or release the solenoid valve, keeping hydraulic or fuel-system functions responsive under working conditions
- Fuel and Hydraulic System Safety — a failed or open-circuit coil can prevent solenoid valves from actuating, causing unintended machine behavior; replacing with a genuine OEM coil restores predictable, controlled operation
A magnetic coil generates the electromagnetic field that actuates a solenoid valve, pulling or releasing its plunger to control the flow of hydraulic fluid or fuel within the machine. On tandem rollers like the BW 161 AD-4 series, these coils are integral to precise hydraulic control and engine fuel-shutoff circuits. When a coil burns out, develops an open circuit, or loses its rated inductance, the solenoid valve it drives will not operate correctly — causing sluggish response, failure to engage, or an inability to shut down the engine through normal means.
