The Wacker Neuson Throttle Plate is a genuine OEM component designed for the RD7H and RD7He series walk-behind tandem rollers. As a direct OEM replacement, this part is manufactured to the exact specifications Wacker Neuson requires for proper engine speed regulation on these machines. The covers a broad range of RD7H and RD7He configurations, including North America-specific double-drum variants, making it the correct choice for operators running machines across multiple serial ranges. Confirm your model and serial number against the fitment list before ordering to ensure a match.
Key Features
- Exact OEM Geometry: — Manufactured to the precise valve profile required by the RD7 carburetor assembly — critical for consistent airflow metering and stable engine response under load.
- Genuine Wacker Neuson Part: — Sourced directly from Wacker Neuson, this is the same throttle plate installed during original production, not an approximated substitute.
- Broad RD7 Series Coverage: — Fits multiple RD7H and RD7He configurations, including walk-behind roller and North America-only double-drum variants across several serial number ranges.
- Restores Proper Engine Speed Control: — A worn or damaged throttle plate causes erratic RPM, poor compaction consistency, and difficulty holding governed speed — replacing it returns the roller to predictable, controlled operation.
- Fuel System Compliance: — Using the correct OEM throttle plate maintains proper air-fuel mixture ratios, helping preserve emissions compliance and protecting the engine from running lean or rich due to an ill-fitting valve.
The throttle plate sits inside the carburetor body and acts as the primary valve controlling the volume of air entering the engine. As the operator adjusts throttle input, the plate rotates to open or restrict airflow, which directly governs engine speed and power output. When the throttle plate becomes worn, warped, or damaged, the engine may surge, stall, or fail to hold a consistent RPM — all of which compromise the roller's ability to deliver uniform compaction passes on asphalt or soil.
