Bomag 05887440 Magnetic Coil

The Bomag 05887440 Magnetic Coil is a genuine OEM component designed for Bomag tandem rollers across the BW 141, BW 151, BW 154, BW 161, BW 170, BW 174, BW 184, BW 190, BW 202, and BW 203 series. Sourced directly from Bomag, this magnetic coil matches the original specification for a dependable, drop-in replacement. Compatible models include the BW 141 AD-4, BW 151 AD-4, BW 154 AD-4, BW 161 AD-4, BW 161 ADH-4, BW 170 AD, BW 170 AD-2 AM, BW 174 AD, BW 174 AD-2, BW 184 AD-2, BW 190 AD-4, BW 202 AD-4, BW 203 AD-4, and additional AM and regional variants. Choosing an authentic Bomag part ensures the coil performs to the same electrical and mechanical standards as the unit it replaces, keeping your tandem roller operating as designed.

Key Features

• Genuine OEM Electrical Spec — manufactured to Bomag's original resistance and inductance ratings, ensuring correct coil engagement and solenoid response specific to these tandem roller hydraulic and vibration control circuits
• Direct-Fit Replacement — engineered to the same connector type, mounting dimensions, and coil geometry as the original, allowing straightforward installation without modification
• Broad Tandem Roller Coverage — fits a wide range of Bomag BW-series tandem rollers including the BW 141 AD-4, BW 154 AD-4 AM, BW 161 ADH-4, BW 174 AD-2, BW 184 AD-2, BW 190 AD-4 AM, BW 203 AD-4 AM, and more
• Consistent Compaction Performance — a properly functioning magnetic coil maintains precise on/off control of the solenoid valve; a worn or open-circuit coil can cause loss of vibration or drive function, disrupting compaction output
• Electrical Safety Integrity — correct coil impedance prevents overloading the machine's electrical system, protecting related solenoid valves and control circuits from heat damage or failure

A magnetic coil generates an electromagnetic field when energized, actuating the solenoid valve it is mounted on to open or close hydraulic or pneumatic flow within the machine. On Bomag tandem rollers, these coils are critical to controlling functions such as vibratory drum engagement and drive direction. When a magnetic coil fails — through an open winding, short circuit, or physical damage — the solenoid valve it controls will not operate, potentially disabling vibration or travel functions entirely. Replacing a faulty coil with a genuine Bomag part restores proper valve actuation and full machine function.
