The Wacker Neuson is a genuine OEM Vent Line Check Valve Sp designed for the BS50-2, BS60-2, BS65-V, and BS70-2 series gasoline vibratory rammers. Sourced directly from Wacker Neuson, this part meets the original engineering specification for the vent line circuit found across the BS rammer family. Fitment spans standard, oil-injected, high-altitude, and variable-speed variants within these series, covering a wide range of shoe sizes from 165 mm/6 in through 330 mm/13 in. Confirm your model number before ordering to ensure a correct application match.

Key Features

  • Genuine OEM One-Way Flow Control — manufactured to the original Wacker Neuson specification, ensuring the valve opens and seats at the correct cracking pressure for the BS rammer vent line circuit.
  • Drop-In Replacement — connects directly to the existing vent line fitting with no reworking of surrounding fuel or air lines required.
  • Broad BS Series Coverage — fits BS50-2, BS50-2i, BS60-2, BS60-2i, BS65-V, BS70-2, and BS70-2i rammers, including EU-spec and high-altitude configurations.
  • Protects Engine Lubrication Integrity — a functioning vent line check valve prevents unwanted pressure or fluid back-flow in the vent circuit; a failed valve can allow oil migration or incorrect crankcase venting, leading to fouled air filters or erratic engine behavior.
  • Fuel System Safety — correct one-way valve function in the vent line prevents vapor lock and unintended fuel or oil venting during transport and operation, keeping the rammer running predictably in demanding trench conditions.

The vent line check valve controls the direction of airflow or fluid movement within the rammer's crankcase vent circuit. It allows pressure to escape in one direction only, preventing blowback that could force oil vapor into the air filter or carburetor. When this valve fails — either sticking open or losing its seat — the engine may run rich, consume excessive oil, or produce visible smoke, and the vent line can become contaminated. Replacing a worn or leaking check valve restores correct crankcase breathing and protects the rest of the engine from the downstream effects of an uncontrolled vent path.
