The Wacker Neuson is a genuine OEM Blue Dot Diaphragm designed for the BS-series vibratory rammers, including the BS30, BS45YA, BS52Y, and BS65Y models. As a direct OEM replacement, part is manufactured to the same specification as the original component, ensuring a correct installation with no guesswork on fitment. This diaphragm is compatible across multiple BS-series shoe sizes and configurations, making it a versatile service part for operators running more than one rammer model. Keep a spare on hand to minimize unplanned downtime during active compaction work.
Key Features
- Genuine OEM Diaphragm Material — Produced to the same compound and thickness spec as the original, maintaining the correct fuel metering response in the carburetor.
- Direct-Fit Replacement — Seats into the carburetor body the same way as the factory part, with no trimming or adapting required for a clean, leak-free installation.
- Broad BS-Series Compatibility — Confirmed fitment across the BS30, BS45YA, BS52Y, and BS65Y rammer models, covering a range of shoe sizes from 152mm/6in through 280mm/11in.
- Restores Proper Fuel Delivery — A cracked or hardened diaphragm causes inconsistent fuel flow, leading to hard starting, rough running, or a rammer that stalls under load; this replacement restores smooth, consistent operation.
- Fuel System Integrity — A correctly seated diaphragm prevents raw fuel from bypassing the metering circuit, keeping the carburetor operating safely and within design parameters.
The diaphragm is a flexible membrane inside the carburetor that responds to engine vacuum and pressure pulses to meter fuel delivery into the combustion chamber. On a vibratory rammer like the BS-series, this component works under constant vibration and exposure to fuel, which causes the material to stiffen, crack, or distort over time. When the diaphragm fails, the carburetor can no longer regulate fuel flow correctly, resulting in poor throttle response, hard starting, or a complete inability to run — replacing it promptly restores the rammer to full working condition.
