The Wacker Neuson Wire Assembly Oil Pressure Switch is a genuine OEM component designed for the RD12-90 Tandem Roller and CRT36-25 Ride-on Trowel series. Sourced directly from Wacker Neuson, this assembly carries the same specifications as the part originally installed at the factory, so it connects and functions exactly as intended. Whether you're servicing a foldable ROPS roller or a 915mm ride-on trowel with a wheel kit, part covers the key configurations within these two machine families.
Key Features
- OEM-Spec Wiring and Connector Integrity — Manufactured to Wacker Neuson's original electrical specifications, ensuring correct resistance, connector fit, and insulation grade for the oil pressure switch circuit.
- Direct Plug-In Replacement — Matches the original harness routing and connector type, so the assembly installs into the existing switch port without splicing or adapting.
- Confirmed Fitment Across Two Machine Families — Compatible with RD12-90 Tandem Rollers (solid ROPS and foldable ROPS variants) and CRT36-25 Ride-on Trowels, including the wheel kit configuration.
- Protects Critical Engine Monitoring — A properly functioning wire assembly maintains a clean, uninterrupted signal path between the oil pressure switch and the machine's control system, keeping engine protection alerts accurate.
- Electrical Safety Compliance — As part of the engine protection circuit, a correctly rated and fully intact wiring assembly helps ensure the oil pressure warning system responds as designed, reducing the risk of undetected low-pressure conditions during operation.
The oil pressure switch wire assembly is the electrical link between the engine's oil pressure switch and the machine's monitoring or shutdown system. When oil pressure drops below a safe threshold, the switch triggers a signal through this wire assembly to alert the operator or initiate a protective engine shutdown. If the wiring is damaged, corroded, or broken, that signal never reaches the control system — meaning the engine can continue running under dangerously low oil pressure without any warning, leading to serious internal engine damage.
