Wacker Neuson 5000216206 Float Needle Valve

The Wacker Neuson Float Needle Valve is a genuine OEM component designed for the CRT48-34V 1220mm/48in Ride-on Trowel and CT48-13A-V Trowel series. As a direct OEM replacement sourced through Wacker Neuson's authorized parts network, this valve is manufactured to the exact specification of the original, ensuring a drop-in installation with no guesswork. Confirmed fitment covers the CRT48-34V and CT48-13A-V platforms, making it a straightforward solution when servicing carbureted fuel systems on these machines.

Key Features

• OEM Fuel System Precision — Manufactured to the exact needle and seat tolerances required for consistent fuel metering, eliminating the flooding and lean-running conditions caused by a worn or damaged valve.
• Direct Drop-In Installation — Engineered to match the original float bowl assembly geometry, so the valve seats and seals correctly without modification or shimming.
• Confirmed Trowel Series Fitment — Compatible with CRT48-34V 1220mm/48in Ride-on Trowels and CT48-13A-V Trowels; verify your model number before ordering to ensure an exact match.
• Stable Fuel Level Control — A correctly functioning float needle valve holds the carburetor's fuel level steady under load, supporting smooth engine throttle response and consistent trowel performance across the finishing pass.
• Fuel System Safety — A failed or leaking float needle valve can allow fuel to overflow into the engine intake or pool in the carburetor bowl, creating a fire risk on powered finishing equipment. Replacing with a genuine OEM part restores the correct shutoff function.

The float needle valve controls fuel delivery into the carburetor's float bowl by opening and closing against a seat as the float rises and falls with the fuel level. When the bowl reaches the correct level, the float lifts the needle to shut off incoming fuel; as fuel is consumed, the float drops and the needle reopens. When this valve wears, sticks, or fails to seal, the carburetor can flood — leading to rough running, hard starting, and potential fuel overflow — or run lean, causing hesitation and power loss under load.
