The Wacker Neuson is a genuine OEM Carburetor Adjustment Screw designed for the BS45Y, BS52Y, and BS60Y series gasoline vibratory rammers. As a direct OEM replacement, this part is manufactured to the exact specifications of the original component, ensuring correct fuel mixture calibration right out of the box. It fits multiple BS-series rammer configurations, including 6-inch and 10-inch shoe variants across the BS45Y, BS52Y, and BS60Y model lines. When carburetor tuning goes off-spec due to a worn or damaged adjustment screw, restoring it with part number brings your rammer back to consistent, reliable operation.
Key Features
- OEM Fuel Mixture Precision — Manufactured to the exact thread pitch and taper angle of the original, ensuring accurate air/fuel ratio adjustment without guesswork.
- Drop-In Carburetor Fit — Installs directly into the carburetor body of compatible BS-series rammers with no modification to the carburetor housing required.
- Broad BS-Series Compatibility — Confirmed fitment across BS45Y, BS52Y, and BS60Y vibratory rammers in both 6-inch and 10-inch shoe configurations.
- Restores Consistent Engine Performance — A correctly set adjustment screw keeps the rammer running at the right RPM and throttle response; a worn or stripped screw leads to rough idle, stalling, and loss of compaction force.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, carrying the same part number used by authorized service centers for BS-series rammer carburetor repairs.
The carburetor adjustment screw controls the flow of the fuel and air mixture entering the engine at idle or low-throttle conditions. By fine-tuning this mixture, the screw allows a technician to optimize combustion efficiency and maintain stable engine speed under load — critical for a vibratory rammer that cycles continuously during trench and cohesive soil compaction. When the screw becomes worn, corroded, or stripped, the engine loses its tuned mixture setting, resulting in hard starting, erratic idle, or loss of power that reduces the rammer's compaction output.
