The Wacker Neuson Coil Complete is a genuine OEM component designed for the RD27-100 and RD27-120 hydrostatic vibratory rollers. Sourced directly from Wacker Neuson, this coil assembly meets the exact electrical specifications of the original part, ensuring correct operation within the machine's control or hydraulic solenoid circuit. The covers a broad range of RD27 configurations, including standard and traction control variants across multiple serial number ranges.
Key Features
- OEM-Matched Electrical Specification — Wound and rated to the same resistance and inductance values as the original, so the solenoid circuit responds predictably under load.
- Direct-Swap Replacement — Designed to drop into the existing coil mount and connector on RD27-series rollers without rework to surrounding hardware.
- Broad RD27 Coverage — Fits RD27-100 and RD27-120 machines in both standard hydrostatic and traction control configurations across multiple production runs.
- Protects Hydraulic System Response — A correctly functioning coil maintains consistent solenoid actuation; a failed or shorted coil can cause erratic drive behavior or complete loss of hydraulic control response.
- Electrical Safety Integrity — Genuine OEM construction ensures the coil insulation and winding grade are rated for the operating voltage and temperature range of the RD27 platform, reducing risk of in-field electrical faults.
A coil complete is the electromagnetic winding assembly that energizes a solenoid valve, converting an electrical signal from the machine's control system into hydraulic action — such as engaging drive, controlling vibration frequency, or activating traction control. When the coil is healthy, it draws consistent current and produces a steady magnetic field that opens or closes the valve precisely on command. If the coil develops an open circuit, a short, or increased resistance from heat damage or moisture intrusion, the solenoid valve may fail to actuate, actuate intermittently, or remain stuck in one position — leading to loss of propulsion, vibration control issues, or traction system faults on the roller.
