The Wacker Neuson Spring Inlet Lever is a genuine OEM Spring Inlet Lever designed for the BS50, BS60, BS70, BS500, BS600, BS700, BS52Y, BS60Y, BS45Y, BS65-V, and BS650 vibratory and oil-injected rammer series. As a factory-sourced component, the is manufactured to the exact tolerances and material specifications required by Wacker Neuson for proper carburetor inlet valve operation. This part covers an exceptionally wide range of rammer configurations — including standard vibratory, oil-injected, variable speed, and high-altitude models — making it the correct choice for a large portion of the Wacker Neuson rammer lineup. When you need a direct, no-guesswork replacement, the delivers the fit and function the machine was built around.

Key Features

  • Genuine OEM Spring Tension Integrity — Manufactured to Wacker Neuson's original spring rate specification, ensuring the inlet lever opens and closes at the correct fuel flow threshold — not too stiff, not too soft.
  • Drop-In Carburetor Fit — Engineered to seat and pivot exactly as the original, with no reshaping or shimming needed during installation in the carburetor assembly.
  • Broad Rammer Series Coverage — Compatible with BS50, BS52Y, BS60, BS60Y, BS65-V, BS70, BS500, BS600, BS650, BS700, and their oil-injected and high-altitude variants, spanning both current and legacy configurations.
  • Consistent Fuel Metering at the Source — A correctly functioning inlet lever maintains steady fuel delivery to the engine; a worn or fatigued spring causes rough running, hard starting, or flooding that no carburetor adjustment will fix.
  • Fuel System Compliance — Using the genuine OEM lever maintains the fuel inlet circuit within the tolerances the engine management was calibrated for, supporting correct air-fuel ratio across all operating conditions.

The Spring Inlet Lever is a small but critical component inside the carburetor's fuel inlet valve circuit. It works in tandem with the inlet needle to regulate how fuel enters the float chamber — when the float drops, the lever releases the needle and allows fuel in; when the chamber is full, it pushes the needle closed. A fatigued or broken spring means the lever cannot apply the correct seating force on the inlet needle, leading to flooding, fuel starvation, or an engine that refuses to idle cleanly. Replacing a worn Spring Inlet Lever restores precise fuel metering and brings the carburetor back to its intended operating balance.
