The Bomag 05877221 Magnetic Coil is a genuine OEM component designed for a wide range of Bomag pavers, tandem rollers, single drum rollers, pneumatic tyred rollers, and trench compactors. Sourced directly from Bomag, this magnetic coil matches the original specification exactly, ensuring a direct drop-in installation with no guesswork on fit or compatibility. This coil is confirmed to fit BF 300-series pavers including the BF 300 P, BF 300 C variants, BW-series tandem rollers such as the BW 100 AD-5, BW 120 AD-5, BW 135 AD-5, and BW 138 AD-5, BW-series single drum rollers including the BW 145 DH-5, BW 177 DH-5, BW 211 DH-5, and BW 213 DH-5 and their PDH and PL variants, the BW 28 RH pneumatic tyred roller, and the BMP 8500 trench compactor. As a genuine OEM part, it meets the same electrical performance standards as the component it replaces, keeping your equipment operating at the level it was engineered to achieve.
Key Features
- Genuine OEM Electrical Specification — matched to the original coil's resistance, inductance, and voltage rating so the solenoid circuit behaves exactly as designed
- Direct-Fit Replacement — engineered to the same mounting dimensions and connector interface as the original, slotting in without modification to wiring or brackets
- Broad Bomag Fleet Coverage — fits BF 300-series pavers, BW-series tandem and single drum rollers including the BW 100, BW 120, BW 135, BW 138, BW 145, BW 177, BW 211, and BW 213 families, the BW 28 RH pneumatic tyred roller, and the BMP 8500 trench compactor
- Consistent Electromagnetic Output — a correctly functioning magnetic coil maintains steady solenoid actuation; a failed or degraded coil causes erratic valve behavior, loss of hydraulic or fuel control, and potential machine shutdown
- Fuel and Hydraulic System Safety — the magnetic coil governs solenoid valves tied to fuel shutoff and hydraulic control circuits; using a properly rated OEM coil is critical to safe, predictable machine operation
A magnetic coil generates the electromagnetic field that actuates a solenoid valve, pulling or releasing a plunger to open or close fluid or fuel flow within the machine. In compaction and paving equipment, these coils are integral to hydraulic control circuits and fuel management systems — when the coil energizes, it enables the valve to shift; when it de-energizes, the valve closes. A coil that has shorted, opened, or degraded in insulation resistance will cause inconsistent valve response, which can manifest as sluggish hydraulic function, engine starting issues, or complete loss of a controlled circuit, making timely replacement essential to maintaining normal machine operation.
