The Wacker Neuson Carburetor Diaphragm is a genuine OEM component designed for the BH 22 and BH 23 series gasoline breakers. As a direct OEM replacement sourced from Wacker Neuson, this diaphragm meets the exact material and dimensional specifications of the original part, ensuring the carburetor functions as intended across compatible BH series machines. Verified fitment covers the BH 22, BH 22 RS, BH 23, BH 23 RS, BH 23 SCH, and BH 23 Loxam, spanning multiple tool holder configurations. Keeping this wear item in serviceable condition is one of the most cost-effective ways to maintain consistent engine starting and fuel delivery performance on your breaker.
Key Features
- OEM-Correct Diaphragm Material — Manufactured to the original fuel-resistant material specification, maintaining the correct flex stiffness and sealing performance that the BH series carburetor requires to meter fuel accurately.
- Drop-In Carburetor Service Fit — Sized and profiled to seat correctly within the carburetor body on BH 22 and BH 23 machines, with no trimming or reworking needed during installation.
- Broad BH Series Coverage — Fits the BH 22, BH 22 RS, BH 23, BH 23 RS, BH 23 SCH, and BH 23 Loxam across multiple tool holder sizes, making it a practical stock item for fleets running mixed BH configurations.
- Restores Clean Fuel Delivery — A cracked or stiffened diaphragm disrupts the fuel-air mixture, causing hard starting, rough running, or engine cut-out under load. Replacing it with part 5000211956 restores proper fuel pulse and consistent power output.
- Fuel System Integrity — A correctly seated carburetor diaphragm prevents unmetered fuel from entering the engine, which is essential for safe, stable operation of a hand-held gasoline breaker in demanding demolition environments.
The carburetor diaphragm is a thin, flexible membrane inside the carburetor that responds to engine vacuum pulses to draw fuel from the tank and deliver a controlled fuel-air mixture to the engine. On gasoline-powered breakers like the BH 22 and BH 23, this diaphragm cycles thousands of times per minute and is exposed to fuel, heat, and mechanical stress. Over time it can stiffen, crack, or distort, which starves the engine of fuel and leads to hard starting, inconsistent throttle response, or a complete inability to run. Replacing a worn diaphragm with a genuine OEM part like the Wacker Neuson 5000211956 is a standard carburetor service step that directly restores engine performance.
