The Wacker Neuson Starter Switch Assembly is a genuine OEM component designed for RD27-100 and RD27-120 hydrostatic vibratory rollers, including standard and traction control configurations. As a direct OEM replacement, this part is sourced and manufactured to the exact specifications Wacker Neuson requires for the RD27 roller series — ensuring it integrates correctly with the machine's ignition and starting circuit. Fitment spans multiple machine numbers across both the RD27-100 and RD27-120 model variants, making the the correct starter switch assembly for a wide range of RD27 builds.
Key Features
- OEM Electrical Specification: — Manufactured to the exact switch resistance, contact rating, and circuit configuration required by the RD27 roller's starting system — no guesswork on compatibility.
- Drop-In Connector Match: — Designed to mate directly with the existing wiring harness on RD27-100 and RD27-120 models, so installation follows the original service procedure without adaptation.
- Broad RD27 Series Coverage: — Confirmed fitment across RD27-100 and RD27-120 variants, including both standard hydrostatic vibratory and traction control equipped machines.
- Starting Circuit Integrity: — A worn or failed starter switch can prevent the roller from cranking entirely or cause intermittent no-start conditions; replacing with the correct OEM part restores dependable engine start-up.
- Genuine Wacker Neuson Part: — Carries the Wacker Neuson OEM designation, confirming it meets the original design intent for the RD27 roller's electrical system.
The starter switch assembly controls the electrical signal that engages the starter motor when the operator initiates the start sequence. It acts as the primary interface between the operator's input and the engine's cranking circuit, routing power correctly while also interacting with safety interlock systems that prevent unintended starting. When the switch assembly fails or becomes worn, the roller may exhibit symptoms ranging from a completely unresponsive starter to erratic or intermittent cranking — bringing compaction operations to a halt until the switch is replaced.
