Wacker Neuson 5000156535 Throttle Flap

The Wacker Neuson Throttle Flap is a genuine OEM component designed for a wide range of Wacker Neuson equipment, including PT2 trash pumps, CT36-6 concrete trowels, VP and WP series single-direction vibratory plate compactors, GP2600 portable generators, BFS floor saws, BPU2540 reversible vibratory plates, and PG3 dewatering pumps. As a direct OEM replacement, part is manufactured to the exact specifications of the original, ensuring a drop-in fit with no guesswork at installation. This throttle flap is the same part shipped with new machines, so you can trust it to restore proper engine response across any of its supported applications. Confirm your model number before ordering to ensure compatibility with your specific machine configuration.

Key Features

• Genuine OEM Carburetor-Matched Tolerances — Manufactured to the exact bore dimensions and edge profile of the original throttle flap, ensuring correct airflow restriction at every throttle position.
• Direct-Mount Replacement — Mounts directly onto the carburetor throttle shaft using the original hardware; no trimming, drilling, or adapter fittings required.
• Broad Cross-Family Fitment — Covers VP/WP vibratory plates, BPU reversible plates, CT36-6 trowels, PT2 and PG3 pumps, GP2600 generators, BFS floor saws, and additional Wacker Neuson models under a single part number.
• Restored Throttle Response — A correctly seating throttle flap maintains the air-fuel ratio the engine was calibrated for, delivering consistent RPM control and preventing rough idling or bogging under load.
• Fuel System Integrity — A warped or worn throttle flap allows unmetered air into the intake, which can cause lean-running conditions and potential engine damage; replacing it promptly protects the engine long term.

The throttle flap sits inside the carburetor bore and acts as the primary valve controlling how much air enters the engine. When you open the throttle, the flap rotates to allow more airflow, which draws in more fuel and increases engine speed; when you release the throttle, it closes to reduce the mixture and return the engine to idle. Over time, the flap can warp, wear at its pivot, or develop carbon buildup that prevents it from sealing or opening fully — symptoms typically show up as an engine that idles erratically, surges, or lacks full-throttle power. Replacing the throttle flap restores the precise airflow control the carburetor depends on for stable, consistent engine operation across all load conditions.
