The Wacker Neuson 5000183785 is a genuine OEM Crankcase Complete designed for the BS50-2i, BS60-2i, and BS70-2i series gasoline vibratory rammers. As a direct OEM replacement, this crankcase is manufactured to the same specification as the original unit, ensuring correct alignment, sealing, and structural integrity within the engine assembly. This part covers a broad range of BS-series rammer configurations, including EU variants, making it the right choice whether you are servicing a standard or European-spec machine. Confirming your model number against the fitment list before ordering is the best way to ensure this is the correct crankcase for your unit.
Key Features
- Genuine OEM Construction: — Manufactured to Wacker Neuson's original material and dimensional tolerances, so the crankcase walls, bearing bores, and sealing surfaces meet the same standards as the unit it replaces.
- Complete Assembly: — Supplied as a Crankcase Complete, meaning the housing arrives ready to accept internal engine components without additional sub-assembly sourcing.
- Broad BS-Series Fitment: — Confirmed compatibility across BS50-2i, BS60-2i, and BS70-2i rammer families, including standard and EU-specification variants.
- Structural Engine Integrity: — A sound crankcase is the foundation of proper crankshaft support and lubrication retention; a cracked or worn crankcase leads to oil loss, bearing failure, and engine seizure.
- Fuel System Separation: — Correct crankcase sealing is critical on two-stroke rammer engines, where crankcase pressure directly drives the fuel-air charge into the combustion chamber; a compromised crankcase causes hard starting, loss of power, and poor compaction performance.
The crankcase is the structural core of the rammer engine, housing the crankshaft, connecting rod, and the internal passages that manage lubrication and, on two-stroke engines, fuel-air transfer. On BS-series vibratory rammers, the crankcase also works as a pressure chamber in the two-stroke cycle, drawing in the fuel-air mixture and transferring it to the cylinder — meaning even a minor crack or seal failure directly disrupts combustion and compaction output. When the crankcase is damaged, warped, or no longer able to hold a proper seal, the engine will run poorly or not at all, and continuing to operate the machine risks secondary damage to the crankshaft and bearings. Replacing it with the correct OEM unit, part number 5000183785, restores the engine to its original operating condition.
