Key Features
- Genuine OEM Flex and Seal Integrity — Manufactured to Wacker Neuson's material specification, this diaphragm delivers the correct flex characteristics and fuel-resistant sealing needed for consistent carburetor operation.
- Drop-In Carburetor Fit — Dimensioned to seat correctly within the carburetor body of BS50-4 and BS60-4 rammers, allowing straightforward installation without modification to the fuel system assembly.
- Broad BS-Series Coverage — Fits BS50-4, BS50-4s, BS60-4, BS60-4s, BS500-4, and BS600-4 models, including standard and EU-specification configurations across multiple machine numbers.
- Consistent Fuel Delivery — A correctly functioning diaphragm maintains the precise fuel-to-air metering your rammer needs to start reliably and run at full compaction output; a cracked or hardened diaphragm typically causes hard starting, rough running, or stalling under load.
- Fuel System Safety — A deteriorated diaphragm can allow raw fuel to pass into unintended areas of the carburetor, creating a potential fuel leak hazard. Replacing it with a genuine OEM part restores the engineered seal barrier.
The diaphragm is a critical flexible membrane within the carburetor's fuel-metering circuit. It responds to engine vacuum and pressure pulses to regulate the flow of fuel into the carburetor, ensuring the correct mixture reaches the engine at varying throttle positions and load levels. Over time, the diaphragm can stiffen, crack, or deform due to exposure to fuel and heat, leading to inconsistent fuel delivery, hard starting, or engine stalling — particularly under the high-vibration, high-load conditions typical of rammer operation. Replacing a worn diaphragm is one of the most common carburetor service steps and directly restores engine responsiveness and starting performance.
