The Wacker Neuson Throttle Valve is a genuine OEM Throttle Valve designed for the RD12-90 Tandem Roller and CRT36-25 Ride-on Trowel series. Sourced directly from Wacker Neuson, this part meets the exact specifications of the original component — no guesswork on fit or function. Confirmed fitment spans both solid ROPS and foldable ROPS configurations of the RD12-90, as well as the standard and Wheel Kit variants of the 915mm/36in CRT36-25 Ride-on Trowel. Ordering by part number ensures you receive the correct valve for your machine the first time.
Key Features
- OEM-Spec Flow Calibration — Manufactured to Wacker Neuson's precise throttle flow tolerances, ensuring accurate engine response and consistent speed control across the operating range.
- Drop-In Replacement — Matches the original valve's port dimensions and connection points, allowing straightforward installation without adapters or modifications to existing fuel or air lines.
- Broad Series Fitment — Compatible with RD12-90 Tandem Rollers (solid and foldable ROPS) and CRT36-25 Ride-on Trowels (standard and Wheel Kit), covering multiple configurations under a single part number.
- Consistent Throttle Response — A properly functioning throttle valve maintains smooth, predictable engine acceleration and deceleration; a worn or sticking valve leads to rough running, surging, or loss of speed control under load.
- Fuel System Integrity — As a genuine OEM component, this valve maintains correct fuel metering tolerances, helping to preserve proper air-fuel ratios and protect engine performance over time.
The throttle valve controls the volume of fuel or air-fuel mixture entering the engine by regulating the opening through which the charge passes in response to operator input. On compaction and finishing equipment like rollers and ride-on trowels, precise throttle control is critical — it directly affects working speed, engine load management, and operator control. When the throttle valve sticks, leaks, or wears out of spec, the engine may surge, hunt for idle, or fail to reach full working speed, reducing output and placing additional strain on the drivetrain.
