The Wacker Neuson Fuel Tank Cap 50:1 is a genuine OEM component designed for the BH 22, BH 23, BH 24, BH 40, BH 55, and BH 65 series gasoline breakers. As a direct OEM part, is manufactured to the same specification as the original cap fitted at the factory, ensuring a correct seal and proper fuel-mix ratio labeling for safe, compliant refueling. This cap fits an extensive range of BH-series breaker configurations, including standard, Low Vibration, and RS variants across multiple tool-holder sizes, making it one of the most widely applicable service items in the BH breaker line.
Key Features
- Correct 50:1 Mix Ratio Marking — The cap is clearly labeled for the 50:1 fuel-to-oil ratio required by BH-series gasoline breakers, supporting accurate mixing every time the tank is filled.
- Genuine OEM Sealing Integrity — Manufactured to Wacker Neuson's original material and thread specification, this cap delivers the compression and fuel-vapor seal expected of a first-fit component.
- Broad BH-Series Coverage — A single part number covers BH 22, BH 23, BH 24, BH 40, BH 55, and BH 65 breakers, including standard, Low Vibration, RS, and region-specific configurations.
- Drop-In Thread Match — Engineered to the original tank neck thread pattern; installs by hand with no tools or thread adapters required.
- Prevents Fuel Contamination and Leaks — A properly sealing fuel tank cap keeps debris and moisture out of the fuel system, protecting the carburetor and engine from damage caused by contaminated or diluted mix fuel.
- Fuel System Safety — A correctly fitting, OEM-spec cap maintains a secure seal under vibration-intensive breaker operation, reducing the risk of fuel spillage during use.
The fuel tank cap seals the fuel tank opening on a gasoline-powered breaker and plays a direct role in safe, clean operation. It keeps the correct 50:1 premix fuel contained and free from dirt, dust, and moisture — all of which are common on demolition and breaking worksites. When a fuel tank cap fails to seal properly — due to a damaged thread, cracked body, or worn gasket — fuel can leak onto hot engine surfaces, and contaminants can enter the fuel system, leading to carburetor fouling and hard-starting or no-start conditions. Replacing a damaged or missing cap with the correct OEM part restores the sealed fuel system the engine depends on for consistent power output.
