The Wacker Neuson is a genuine OEM Temperature Switch designed for the RD27-100 and RD27-120 Hydrostatic Vibratory Rollers. As a direct OEM replacement sourced through authorized Wacker Neuson supply channels, part is manufactured to the exact specification of the original component it replaces. This switch is confirmed to fit multiple configurations of the RD27 series, including standard Hydrostatic Vibratory Roller builds and Traction Control-equipped variants across a wide range of machine numbers.
Key Features
- OEM-Spec Switching Threshold — Activates at the correct temperature setpoint for the RD27 series, ensuring the machine responds to thermal events exactly as engineered.
- Direct Plug-In Replacement — Matches the original connector and thread specification of the RD27-100 and RD27-120, so installation requires no re-wiring or thread adaptation.
- Broad RD27 Series Coverage — Compatible with both the RD27-100 and RD27-120 in standard and Traction Control configurations, covering a wide production run of Hydrostatic Vibratory Rollers.
- Protects Critical Drive and Engine Systems — A properly functioning temperature switch triggers shutdowns or alerts before thermal damage can reach hydraulic or engine components; a failed switch leaves those systems unprotected.
- Electrical Safety Compliance — As a thermal protection component, using a correctly rated OEM switch ensures the machine's safety shutdown logic operates within the parameters Wacker Neuson designed and validated.
The temperature switch monitors the thermal condition of a fluid or component within the machine — typically engine coolant or hydraulic oil — and sends a signal to the control system when a defined temperature threshold is reached. On a tandem roller like the RD27 series, this signal can trigger a warning light, an audible alarm, or an automatic shutdown, protecting the engine and hydrostatic drive from overheating damage. When the switch fails or reads inaccurately, the machine may shut down unexpectedly under normal operating temperatures, or worse, fail to shut down when genuine overheating occurs — either outcome results in lost productivity or costly internal damage.
