The Wacker Neuson Tank Cap is a genuine OEM component designed for the BS50, BS60, BS65, BS70, and BS72 series gasoline and battery-assisted vibratory rammers. As a direct OEM replacement, part is manufactured to the same specification as the original, ensuring a correct, secure seal on the fuel tank. Fitment covers a wide range of BS-family rammer configurations including 11-inch and 6-inch stroke variants across both 2-stroke-plus and 4-stroke models. Keep a spare on hand — a damaged or missing tank cap can bring a rammer to a standstill on the job.
Key Features
- OEM Fuel Integrity: — Manufactured to exact Wacker Neuson specification, ensuring a proper pressure-rated seal that prevents fuel spillage and vapor loss during operation.
- Direct Threaded Replacement: — Matches the original tank neck thread pattern on BS-series rammers for a straightforward swap with no adaptation needed.
- Broad BS-Family Fitment: — Compatible with BS50, BS60, BS65, BS70, and BS72 series rammers across multiple model variants, including US, standard, and CN configurations.
- Protects Engine Performance: — A correctly sealing tank cap maintains consistent fuel delivery to the carburetor; a cracked or loose cap introduces air, disrupts fuel flow, and leads to hard starts or stalling.
- Fuel System Safety: — A compromised tank cap risks fuel leaks near hot engine components. Replacing a worn or damaged cap promptly is a straightforward step that keeps the fuel system closed and the operator safe.
The tank cap seals the fuel tank opening on a vibratory rammer, preventing fuel from escaping during the machine's high-frequency vertical strokes and while in transport. It also keeps debris, dust, and moisture out of the fuel supply, which protects the carburetor and fuel system from contamination. When the cap's seal degrades, cracks, or the cap goes missing entirely, fuel can leak onto hot engine surfaces or the tank can lose its sealed environment — causing rough running, fuel waste, or a complete inability to operate until it is replaced.
