The Wacker Neuson is a genuine OEM Oil Pressure Switch designed for the RD12A-90 Tandem Roller series and CRT36-26A and CRTv36-26A Trowel series. Sourced directly from Wacker Neuson, this switch meets the exact electrical and pressure specifications of the original component installed at the factory. It covers a broad range of configurations within these model families, including foldable ROPS variants and wheel kit-equipped trowels, making it the right choice whether you are servicing a roller or a ride-on trowel. When you need a dependable, properly matched replacement, the delivers the fit and function the machine demands.
Key Features
- Correct Switching Threshold: — Genuine OEM calibration ensures the switch opens and closes at the pressure range Wacker Neuson specifies, so the protection circuit triggers accurately every time.
- Direct Electrical Connector Match: — The 5000226515 uses the original connector and thread pattern, allowing straightforward installation without adapter fittings or wiring modifications.
- Broad Model Coverage: — Fits RD12A-90 Tandem Roller variants and the full CRT36-26A and CRTv36-26A Trowel lineup, including standard, foldable ROPS, and wheel kit configurations.
- Engine Protection You Can Count On: — A properly functioning oil pressure switch shuts the engine down before low-oil conditions cause internal damage; a faulty switch leaves the engine running unprotected or causes unnecessary nuisance shutdowns.
- Critical Safety Circuit Component: — As part of the engine protection system, this switch plays a direct role in preventing catastrophic engine failure on the jobsite, making OEM-spec accuracy essential.
- Genuine Wacker Neuson Part: — Supplied as an authentic OEM component, the 5000226515 is held to the same quality standards as the original part shipped with the machine.
An oil pressure switch monitors the lubrication system and signals the engine's control circuit when oil pressure drops below a safe operating threshold. When pressure falls too low, the switch triggers a shutdown or warning to protect the engine from running without adequate lubrication — damage that can be severe and costly. A failed or out-of-calibration switch can either allow the engine to run unprotected during a real low-pressure event or cause false shutdowns that interrupt work, making prompt replacement with a properly rated part essential.
