The Wacker Neuson 5100036641 Air Purge Complete is a genuine OEM assembly designed for the BS50-2, BS50-2i, BS60-2i, BS65-V, BS70-2, and BS70-2i series gasoline vibratory rammers. As a direct OEM replacement, this part is produced to the same specifications as the original component installed at the factory, ensuring a seamless fit across all covered machine numbers in the BS rammer family. If your rammer's fuel system is showing signs of hard starting, air lock, or difficulty priming, the 5100036641 Air Purge Complete is the correct service part to restore proper operation. Confirm your machine number against the fitment list before ordering to ensure compatibility.
Key Features
- Genuine OEM Fuel System Integrity — Manufactured to Wacker Neuson's original material and flow specifications, ensuring the purge bulb and housing maintain proper fuel line pressure for consistent priming.
- Complete Assembly — Supplied as a complete unit, so all purge components are replaced together in a single service step — no need to source individual sub-components separately.
- Broad BS Rammer Compatibility — Verified fitment across BS50-2, BS50-2i, BS60-2i, BS65-V, BS70-2, and BS70-2i series rammers, covering a wide range of machine numbers within the Wacker Neuson jumping jack lineup.
- Restores Cold-Start Performance — A functioning air purge allows the operator to clear air from the fuel line before starting, which is critical for reliable ignition on a gasoline rammer — especially in cold or intermittent-use conditions.
- Fuel System Safety — A cracked, hardened, or failed purge bulb can allow fuel leaks at the carburetor inlet. Replacing the 5100036641 Air Purge Complete with a genuine OEM unit helps maintain a sealed, leak-free fuel delivery path.
The air purge assembly — commonly called a primer bulb assembly — is a manual pump integrated into the fuel line between the tank and carburetor. When pressed, it draws fuel forward and displaces air trapped in the line, allowing the carburetor to receive a fuel-rich mixture before the engine is cranked. On a gasoline rammer like the BS50-2 or BS70-2i, this step is essential after extended storage or fuel system servicing. When the purge bulb cracks, stiffens, or its fittings fail, air cannot be cleared from the line, resulting in extended cranking, rough starts, or a complete failure to start. Replacing the complete assembly restores the fuel priming circuit to its original condition.
