The Bomag 05818273 Coil is a genuine OEM component designed for BW 177 series single drum rollers, covering the D-3, DH-3, PDH-3, D-40, DH-40, PDH-40, D-50, DH-50, and PDH-50 variants including USA-market machines. Sourced directly from Bomag, this coil matches the original electrical specifications of the machines it serves, ensuring a direct, hassle-free installation. When a coil fails or degrades, machine control functions that depend on it can become unreliable — replacing it with an authentic Bomag part restores correct operation and helps protect the surrounding electrical system.
Key Features
- Genuine OEM Electrical Integrity — wound and rated to Bomag's original specifications, delivering the correct resistance and electromagnetic output for consistent coil performance in the BW 177 series
- Direct Drop-In Replacement — engineered to the same dimensions and connector configuration as the original, so this coil installs in place of the worn unit without modification
- Broad BW 177 Series Coverage — fits BW 177 D-3, BW 177 DH-3, BW 177 PDH-3, BW 177 D-40, BW 177 DH-40, BW 177 PDH-40, BW 177 D-50, BW 177 DH-50, BW 177 PDH-50, and corresponding USA-market single drum rollers
- Sustained Electrical Performance — a correctly functioning coil maintains dependable actuation of the valve or solenoid it drives; a failed coil can cause erratic or complete loss of the controlled function, halting productive compaction work
- Verified Part Number Fit — order with confidence using Bomag part number 05818273, cross-referenced to the BW 177 series catalog to confirm compatibility before the part ships
A coil is an electromagnetic winding that generates a magnetic field when energized, typically used to actuate a solenoid valve controlling hydraulic or fuel flow within the machine. On Bomag BW 177 single drum rollers, the coil plays a key role in directing hydraulic functions or managing engine fuel delivery, depending on its location in the system. When a coil shorts, opens, or loses efficiency, the valve it controls may stick, fail to shift, or respond inconsistently — leading to loss of drive, vibration control, or other critical machine functions until the component is replaced.
