The Wacker Neuson 5100021110 Crankshaft Complete is a genuine OEM component designed for the BS-series gasoline vibratory rammer line. This is the complete crankshaft assembly, sourced directly from Wacker Neuson to meet the exact tolerances and material specifications of the original part. Fitment covers a wide range of BS-series rammer models including the BS30, BS50-2, BS50-2plus, BS60-2, BS60-2plus, BS70-2, and BS70-2plus. When a worn or damaged crankshaft threatens your compaction output, part number 5100021110 is the direct OEM solution to restore full operation.
Key Features
- OEM-Spec Crankshaft Geometry — Machined to the original stroke and journal dimensions, ensuring correct eccentric motion and full compaction force output from the rammer.
- Complete Assembly — Supplied as a Crankshaft Complete, so all core rotating components arrive ready to install as a matched unit without sourcing individual sub-parts.
- Broad BS-Series Compatibility — Fits BS30, BS50-2, BS50-2plus, BS60-2, BS60-2plus, BS70-2, and BS70-2plus gasoline rammer models across multiple configurations including 6-inch and 11-inch stroke variants and US-market editions.
- Restores Full Impact Energy — A worn crankshaft causes irregular stroke, loss of compaction force, and accelerated wear on surrounding engine and drive components; replacing with this OEM part returns the rammer to rated performance.
- Genuine Wacker Neuson Part — Backed by Wacker Neuson's OEM supply chain, confirming correct part number 5100021110 and eliminating the guesswork of cross-referencing aftermarket alternatives.
The crankshaft is the central rotating component in the rammer's engine and exciter system, converting the combustion stroke into the reciprocating motion that drives the rammer foot up and down against the soil. In a vibratory rammer like the BS-series, the crankshaft must maintain precise stroke geometry to deliver consistent impact energy for effective cohesive soil and trench compaction. When the crankshaft wears, develops bearing damage, or fails, the rammer loses stroke consistency, compaction performance drops sharply, and continued operation risks cascading damage to the connecting rod, piston, and drive housing.
