The Wacker Neuson 5100015790 Crankcase Complete is a genuine OEM crankcase assembly designed for the BS50-4As, BS60-4As, and BS70-4As series gasoline vibratory rammers. As a direct OEM replacement, this complete crankcase unit is sourced and manufactured to the same specifications as the original component installed at the factory, ensuring a true drop-in fit for the applicable BS-series machines. Fitment covers multiple BS50-4As, BS60-4As, and BS70-4As configurations including 280 mm and 11-inch shoe variants, making part number 5100015790 a widely applicable replacement across the BS rammer lineup.
Key Features
- Genuine OEM Structural Integrity — Cast and machined to the original design tolerances, ensuring the crankcase walls, bearing bores, and sealing surfaces meet the specs the engine was built around.
- Complete Assembly — Supplied as a Crankcase Complete unit, reducing the need for sourcing individual sub-components and simplifying the rebuild or repair process.
- Broad BS-Series Fitment — Confirmed for BS50-4As, BS60-4As, and BS70-4As vibratory rammers across 280 mm and 11-inch shoe configurations, covering a wide range of machine numbers in the BS rammer family.
- Engine Foundation Accuracy — The crankcase is the structural core of the rammer engine; an OEM-matched replacement ensures proper crankshaft alignment, bearing support, and oil retention critical to engine longevity.
- Fuel and Oil Sealing Compliance — Correct crankcase sealing surfaces are essential for maintaining proper engine compression and preventing oil contamination — using a properly dimensioned OEM replacement supports safe, compliant engine operation.
The crankcase is the foundational housing of the rammer's two-stroke or four-stroke engine, enclosing the crankshaft, connecting rod, and primary bearing surfaces while containing the engine oil and maintaining the pressure environment the engine depends on to run correctly. On a vibratory rammer like the BS50-4As, BS60-4As, or BS70-4As, the crankcase is subject to continuous high-frequency vibration loads in addition to normal engine stresses, making material integrity and dimensional accuracy especially important. A cracked, warped, or worn crankcase leads to oil leaks, loss of compression, bearing failure, and ultimately a machine that cannot deliver consistent compaction force in the trench.
