The Wacker Neuson Carburetor Diaphragm is a genuine OEM component designed for the BH 22 and BH 23 series petrol breakers. As a direct Wacker Neuson OEM part, the is manufactured to the same specification as the original, ensuring a correct fit in the carburetor assembly without guesswork or modification. This diaphragm is a critical fuel-system component — a worn or ruptured unit will prevent the breaker from starting or cause it to run erratically, making prompt replacement essential to keeping your machine operational. Confirm your model number before ordering to ensure this is the correct diaphragm for your specific BH series breaker.
Key Features
- OEM-Grade Diaphragm Material — Manufactured from the same fuel-resistant diaphragm compound as the original, maintaining correct flex characteristics and seal integrity under repeated pressure cycling.
- Drop-In Carburetor Fit — Designed to seat correctly within the carburetor body of BH 22 and BH 23 petrol breakers, aligning with existing ports and retaining hardware without rework.
- BH Series Breaker Compatibility — Confirmed fitment for the BH 22 RS and BH 23 RS petrol breakers; always cross-reference your machine model number before ordering.
- Restores Fuel Metering Accuracy — A healthy diaphragm maintains consistent fuel delivery to the engine. A failed diaphragm causes hard starting, rough running, or a complete no-start condition — replacing it restores proper carburetor function.
- Fuel System Safety — A cracked or perforated diaphragm can allow fuel to migrate into unintended areas of the carburetor. Installing a genuine OEM replacement eliminates this risk and keeps the fuel circuit operating as designed.
The carburetor diaphragm is a flexible membrane inside the carburetor that responds to engine vacuum to draw fuel from the tank and meter it into the combustion circuit. On small gasoline-powered equipment like the BH series petrol breakers, this diaphragm replaces the function of a float and bowl system, making it especially important in equipment that operates at varied angles. Over time, exposure to fuel and mechanical flexing causes the diaphragm to stiffen, crack, or develop pinholes — any of which will disrupt fuel delivery and affect how the engine starts and runs. Replacing a worn diaphragm is one of the most effective carburetor service steps for restoring consistent engine performance.
