The Wacker Neuson Control Device is a genuine OEM component designed for a wide range of Wacker Neuson RD and RC series tandem rollers, including the RD18, RD24, RD27, RD40, RD45, RC50, and RC70 model families. Sourced directly from Wacker Neuson, this part carries the same specifications as the original unit installed at the factory. It fits across numerous configurations within these series — including standard, cab, ROPS, DPF, and open-canopy variants — making it a versatile replacement for fleet operators and service technicians alike. Verify your machine's model number against the fitment list before ordering to confirm compatibility.
Key Features
- Genuine OEM Electrical Specification — Manufactured to Wacker Neuson's exact output and signal requirements, ensuring correct communication between machine systems without calibration guesswork.
- Direct-Fit Replacement — Designed to connect and mount using the original hardware points, matching the existing wiring harness interface on supported models.
- Broad Series Compatibility — Fits RD18, RD24, RD27, RD40, RD45, RC50, and RC70 series tandem rollers across standard, cab, ROPS, DPF CAB, and DPF ROPS configurations.
- Restored Operational Control — A functioning control device keeps machine inputs responsive and accurate; a failed unit can cause erratic operation or complete loss of operator control response.
- Electrical System Integrity — As a genuine OEM part, the 5100066916 meets the electrical safety and compliance standards required for correct machine operation on regulated worksites.
The control device acts as a central input or regulation component within the machine's electrical or hydraulic control circuit, translating operator commands into precise machine responses. When this component is worn or faulty, the machine may respond erratically, fail to respond to inputs correctly, or shut down unexpectedly — all of which can disrupt compaction work and create unsafe operating conditions. Replacing it with a genuine Wacker Neuson part restores proper signal handling and keeps the roller performing as intended.
