The Wacker Neuson 5100009982 is a genuine OEM Crankcase Complete designed for the BS50-2, BS60-2, BS65-V, and BS70-2 series gasoline vibratory rammers. As a direct OEM replacement, this crankcase is manufactured to the same specifications as the original unit fitted at the factory, ensuring a correct, trouble-free installation. This part covers a wide range of BS-series rammer variants — including 6-inch, 10-inch, and 11-inch shoe configurations — making it an essential stock item for fleet operators and service technicians who maintain multiple units. Confirm your machine number against the fitment list before ordering to ensure compatibility with your specific rammer configuration.
Key Features
- Genuine OEM Structural Integrity — Cast and machined to OEM tolerances, this crankcase maintains the precise bore geometry and sealing surfaces required to keep the engine assembly correctly aligned and leak-free.
- Drop-In OEM Replacement — Engineered as a direct replacement for the original crankcase; all mounting points, port locations, and mating surfaces align with the original hardware and gaskets.
- Broad BS-Series Fitment — Compatible with multiple variants of the BS50-2, BS60-2, BS65-V, and BS70-2 gasoline vibratory rammers, including 6-inch, 10-inch, and 11-inch shoe configurations across numerous machine numbers.
- Protects Critical Engine Components — A sound crankcase is the structural foundation of the two-stroke engine assembly; cracks, warping, or damage to this housing leads to oil loss, bearing failure, and complete engine seizure if not addressed promptly.
- Fuel System Containment — The crankcase forms a sealed chamber that is integral to the two-stroke scavenging cycle; a properly sealed unit ensures correct fuel-air mixture delivery and prevents oil migration into the combustion chamber.
The crankcase is the primary structural housing of the rammer's two-stroke engine, enclosing the crankshaft, connecting rod, and main bearings while forming the sealed pressure chamber that drives the two-stroke scavenging cycle. In a vibratory rammer, the crankcase also transfers the reciprocating motion of the engine to the rammer's drive mechanism, meaning any structural compromise directly affects both engine function and compaction output. A cracked or warped crankcase allows air leaks that disrupt the fuel-air mixture, cause hard starting, loss of power, or engine seizure — making timely replacement critical to keeping the rammer operational.
