The Wacker Neuson 5200018672 is a genuine OEM Diaphragm designed for the BS50-4As, BS60-4As, and BS70-4As series gasoline vibratory rammers. As a direct factory replacement, this part is manufactured to the same specifications as the original component installed at the plant, ensuring seamless integration with your existing fuel system. Fitment spans a wide range of BS-series rammer configurations including 280 mm shoe models, 11-inch plastic shoe variants, high-altitude editions, and units equipped with hour meters. Verify your machine number against the confirmed compatibility list before ordering to ensure an accurate match.
Key Features
- OEM-Grade Fuel System Integrity — Manufactured from fuel-resistant flexible material rated to maintain the correct pressure differential within the carburetor circuit, preventing lean-run conditions and hard-start faults.
- Drop-In Carburetor Replacement — Engineered to the original dimensional profile, this diaphragm seats and seals correctly within the carburetor body without modification to the housing or fuel circuit.
- Broad BS-Series Compatibility — Confirmed fitment across BS50-4As, BS60-4As, and BS70-4As rammer models, including 280 mm shoe, 11-inch plastic shoe, high-altitude, GRX, and hour-meter-equipped configurations.
- Restored Throttle Response and Idle Stability — A fresh diaphragm restores the carburetor's ability to meter fuel precisely across all throttle positions, eliminating the rough idle, surging, and power loss caused by a cracked or stiffened unit.
- Fuel System Safety — A failed or perforated diaphragm can allow raw fuel to migrate past the carburetor circuit. Replacing a worn diaphragm promptly eliminates this fuel-handling risk on the rammer.
The diaphragm is a thin, flexible membrane located inside the carburetor that pulses in response to crankcase pressure fluctuations, drawing fuel from the tank and delivering it into the venturi for combustion. On a vibratory rammer like the BS50-4As, BS60-4As, and BS70-4As, where the engine operates under constant high-frequency vibration, the diaphragm is subject to accelerated fatigue. Over time it can stiffen, crack, or develop pinholes that disrupt fuel metering, causing symptoms such as hard starting, unstable idle, loss of power, or the engine refusing to run at full throttle. Replacing the diaphragm with a genuine OEM unit restores correct fuel delivery and returns the rammer to full compaction output.
