The Wacker Neuson is a genuine OEM Diaphragm designed for the BS50-4 and BS60-4 series four-stroke vibratory rammers. Sourced directly from Wacker Neuson, this part meets the same specifications as the original component installed at the factory. It is compatible across a wide range of BS50-4 and BS60-4 model configurations, including EU variants, making it a dependable choice for contractors maintaining rammers in the field.

Key Features
- OEM-Matched Membrane Material — Manufactured to the same material grade and flex tolerance as the original, ensuring consistent fuel or air pulse delivery through the carburetor system.
- Drop-In Replacement — Designed to seat and seal identically to the part it replaces, with no rework needed to the surrounding carburetor housing or fittings.
- Broad BS-Series Fitment — Fits BS50-4, BS50-4s, BS60-4, BS60-4s, BS500-4, and BS600-4 rammers across multiple machine configurations, including EU-spec models.
- Restores Proper Carburetor Pulse Action — A cracked or hardened diaphragm causes rough running, hard starting, and fuel delivery issues; replacing it with 5000158660 restores clean, consistent engine operation.
- Fuel System Integrity — A correctly functioning diaphragm is essential to maintaining sealed fuel pathways; using a genuine OEM part helps prevent fuel leaks and unmetered air ingestion.
The diaphragm is a flexible membrane located within the carburetor that responds to crankcase pressure pulses to draw fuel from the tank and meter it into the engine. On vibratory rammers like the BS50-4 and BS60-4, the carburetor diaphragm works continuously under vibration and heat cycling, which causes it to stiffen, crack, or deform over time. When the diaphragm fails, the engine may be difficult to start, run lean, surge, or stall under load — replacing it promptly is one of the most cost-effective carburetor service steps available.
