The Bomag 05877272 Magnetic Coil is a genuine OEM component designed for Bomag BW-series tandem rollers, BW 28 RH pneumatic tyred rollers, and BMP 8500 trench compactors. Sourced directly from Bomag, this magnetic coil carries the same part specifications as the coil installed at the factory, ensuring an exact match to the original electrical and dimensional requirements. This coil fits the BW 100 AD-5, BW 100 AC-5, BW 120 AD-5, BW 120 AC-5, BW 135 AD-5, BW 138 AD-5, BW 138 AC-5, BW 28 RH, and BMP 8500 (including Kohler and Kubota-engined variants). Ordering by part number 05877272 confirms you are getting the correct coil for your machine — no guesswork, no adaptation required.
Key Features
- Genuine OEM Electrical Specification — matched to the original coil's resistance and magnetic output ratings, so the solenoid or valve it drives engages with the correct force and response time
- Direct Drop-In Replacement — engineered to the same connector type and mounting dimensions as the original, allowing straightforward installation without reworking the wiring harness or bracket
- Broad Tandem Roller Coverage — fits BW 100 AD-5, BW 100 AC-5, BW 120 AD-5, BW 120 AC-5, BW 135 AD-5, BW 138 AD-5, and BW 138 AC-5 tandem rollers, plus BW 28 RH pneumatic tyred rollers and BMP 8500 trench compactors including Kohler and Kubota engine variants
- Consistent Solenoid Activation — a functioning magnetic coil maintains precise, repeatable actuation of the hydraulic or fuel-circuit solenoid it controls; a degraded coil can cause erratic engagement, sluggish response, or complete system dropout
- Electrical System Integrity — correct coil impedance prevents over-current conditions that can damage the solenoid valve body or associated control modules, making this a safety-relevant component in the machine's hydraulic or fuel control circuit
A magnetic coil generates the electromagnetic field that pulls the plunger of a solenoid valve, opening or closing a hydraulic or fuel passage on command from the machine's control system. When the coil is energized, the resulting magnetic force moves the valve spool or needle with precise timing — critical for functions such as vibration engagement, travel drive, or fuel shutoff. When a coil fails — through winding burnout, insulation breakdown, or connector corrosion — the solenoid it controls stops responding, which can disable a key machine function entirely and leave the roller or compactor unable to operate as intended.
