The Wacker Neuson Crankcase 2 Takt is a genuine OEM component designed for BS50-2 and BS60-2 series rammers. As a direct OEM part sourced through authorized Wacker Neuson supply channels, the delivers the exact dimensional tolerances and material spec the engine assembly requires. Confirmed fitment spans multiple BS50-2 and BS60-2 configurations, including 6-inch, 10-inch, and 11-inch variants. When you need a verified, like-for-like replacement that drops straight into the existing engine block assembly, this is the correct part.
Key Features
- OEM Casting Integrity — Manufactured to Wacker Neuson's original casting and machining tolerances, ensuring proper bore geometry and sealing surface finish critical for a 2-stroke crankcase.
- Direct Engine Block Replacement — Matches all original mounting points, bearing bores, and port alignments so the engine assembly goes back together without modification to surrounding components.
- Broad BS50-2 and BS60-2 Compatibility — Fits 6-inch, 10-inch, and 11-inch variants across the BS50-2 and BS60-2 rammer series, covering a wide range of job site compaction machines.
- 2-Stroke Engine Integrity — A correctly sealed and dimensionally accurate crankcase maintains proper crankcase compression pressure, which is essential for fuel-air mixture draw and consistent rammer performance.
- Fuel System Containment — The crankcase forms part of the sealed fuel-air circuit in a 2-stroke engine; a warped or cracked case allows pressure loss and fuel vapor leaks, making an OEM-spec replacement the correct choice for safe engine operation.
The crankcase is the structural core of a 2-stroke engine, housing the crankshaft and forming the sealed lower chamber that generates the pressure differential needed to draw the air-fuel mixture into the combustion cycle. In a rammer like the BS50-2 or BS60-2, this component endures constant vibration and impact loads alongside the thermal cycling of the engine. A cracked, worn, or warped crankcase compromises crankcase compression, leading to hard starting, loss of power, excessive fuel consumption, or complete engine failure — making prompt replacement with the correct OEM part essential to restoring full machine output.
