The Wacker Neuson Relay is a genuine OEM relay designed for the RD27-100 and RD27-120 hydrostatic vibratory rollers, as well as the CRT48 and CRT60 series power trowels. Sourced directly from Wacker Neuson, this part meets the exact electrical specifications required by the OEM circuit design — ensuring proper switching behavior and circuit protection in demanding job conditions. It covers a wide range of serial configurations across the RD27 and CRT lines, including the RD27 Pro Tandem Roller, the RD27 Tandem Roller, the CRT48-37V Power Steer, the CRT48-35V Power Steer, and the CRT60-74L and CRT60-74LX trowels.
Key Features
- Correct Switching Specification — Matches the OEM-rated coil voltage and contact load for the RD27 and CRT electrical systems, so the relay activates and releases at the correct thresholds.
- Genuine Wacker Neuson OEM Part — Supplied as an authorized OEM component under part number 5200025182, built to the same design standard as the relay that came in your machine.
- Broad RD27 and CRT Series Coverage — Fits RD27-100 and RD27-120 ride-on rollers across multiple serial configurations, plus CRT48 and CRT60 power trowel variants with power steer systems.
- Drop-In Electrical Connector Fit — Designed to seat directly into the OEM relay socket without rewiring or adapter hardware, keeping the installation straightforward.
- Protects Critical Machine Functions — A failed relay can cause intermittent or total loss of control over hydraulic, drive, or auxiliary circuits; replacing it promptly restores correct electrical switching and full machine operability.
- Electrical Safety Compliance — As an OEM-specified electrical component, this relay is rated for the correct load and duty cycle — using an undersized or non-specified relay in these circuits risks overheating and unintended circuit behavior.
A relay is an electrically operated switch that allows a low-current control signal — from an operator input or control module — to switch a higher-current circuit on or off without direct mechanical contact. In machines like the RD27 roller and CRT trowel series, relays are used to manage key powered functions such as hydraulic solenoid activation, engine control circuits, and auxiliary systems. When a relay fails, the circuit it controls may become stuck open, causing the function to stop working entirely, or stuck closed, causing it to operate continuously regardless of operator input — either condition can affect safe and productive machine operation.
