The Wacker Neuson Diaphragm Assembly is a genuine OEM component designed for the BS50-2, BS50-2i, BS60-2, BS60-2i, BS70-2, BS70-2i, and BS65-V series vibratory rammers, including two-cycle, oil-injected, variable speed, and BG Bau Approved variants across a wide range of shoe sizes. As a factory-authorized part, the meets the exact material and dimensional standards set by Wacker Neuson for this application, ensuring a consistent, trouble-free installation. This assembly covers an extensive fitment range spanning multiple generations of BS-series rammers with shoe sizes from 150 mm/6 in through 330 mm/13 in, including US, EU, high-altitude, and low-HAV configurations. When you need to restore proper carburetor circuit performance on your Wacker Neuson rammer, the is the correct OEM-specified part for the job.
Key Features
- OEM-Matched Diaphragm Material — Manufactured to Wacker Neuson's exact durometer and chemical-resistance specifications, so the diaphragm flexes and seals correctly under fuel and pulsation pressure without premature cracking or deformation.
- Drop-In Assembly Format — Supplied as a complete diaphragm assembly, aligning with existing mounting points and gasket surfaces for a straightforward carb-circuit replacement without trimming or modification.
- Broad BS-Series Compatibility — Fits BS50-2, BS50-2i, BS60-2, BS60-2i, BS70-2, BS70-2i, and BS65-V rammers across two-cycle, oil-injected, variable speed, high-altitude, low-HAV, and BG Bau Approved variants with shoe sizes from 150 mm through 330 mm.
- Restores Consistent Fuel Delivery — A failed or hardened diaphragm causes erratic idling, hard starting, and fuel starvation under load. Replacing it with the correct OEM assembly returns the rammer to stable, responsive operation.
- Fuel System Integrity — A properly functioning diaphragm maintains the sealed fuel circuit that prevents raw fuel leaks within the carburetor body — an important consideration when working in confined or enclosed compaction environments.
The diaphragm assembly is a critical flexible membrane inside the carburetor that pumps fuel from the tank to the metering circuit using pressure and vacuum pulses generated by the engine crankcase. It acts as both a fuel pump and a pressure-regulated valve, maintaining the correct fuel delivery rate across varying engine speeds and load conditions. When the diaphragm stiffens, tears, or develops pinholes with age or fuel exposure, the carburetor loses its ability to meter fuel accurately — resulting in hard starting, rough running, or a complete no-start condition that cannot be resolved by adjustment alone.
