The Wacker Neuson is a genuine OEM Choke Assembly Shaft designed for the BS50-4, BS50-4s, BS60-4, and BS60-4s series four-stroke vibratory rammers. Sourced directly from Wacker Neuson, this part meets the exact specifications of the original component installed at the factory. It fits a broad range of BS-series rammer configurations, including EU-spec variants of the BS50-4s and BS60-4s, making it a reliable go-to replacement across the BS50 and BS60 rammer family. When the choke assembly shaft wears or fails, proper cold-start fuel enrichment is compromised — replacing it with part number restores correct carburetor choke function.
Key Features
- Genuine OEM Construction: — Manufactured to Wacker Neuson's original tolerances, ensuring the choke shaft seats and rotates within the carburetor housing exactly as the original component did.
- Direct Drop-In Replacement: — Matches the original mounting dimensions and shaft geometry of the BS50-4 and BS60-4 carburetor assemblies, so installation follows the standard service procedure without additional fitting.
- Broad BS-Series Compatibility: — Confirmed fitment across BS50-4, BS50-4s, BS60-4, BS60-4s, and their EU-spec counterparts, covering a wide range of Wacker Neuson four-stroke rammer configurations.
- Restored Cold-Start Performance: — A functioning choke shaft allows the operator to correctly enrich the fuel mixture during cold starts, getting the rammer running quickly even in low-temperature conditions.
- Verified Part Number Integrity: — Ordering by part number 5000158653 eliminates guesswork and ensures you receive the correct shaft for your specific BS-series rammer model and machine number.
The choke assembly shaft is the mechanical link between the choke lever and the choke plate inside the carburetor. When the operator activates the choke, this shaft rotates to partially close the air intake, enriching the fuel-air mixture needed to start a cold engine reliably. Over time, the shaft can wear, corrode, or seize within its bore, causing the choke plate to stick open or fail to return to the run position — leading to hard starts, rough idling, or excessive fuel consumption. Replacing a worn or damaged choke assembly shaft promptly keeps the carburetor operating through its full range of motion and maintains consistent engine starting behavior on the jobsite.
