The Wacker Neuson Crankcase is a genuine OEM component designed for BS500, BS600, BS650, and BS700 series vibratory rammers. Sourced directly from Wacker Neuson, this crankcase matches the exact specifications of the original part, ensuring a correct fit across the wide range of BS-series rammer configurations it covers — including standard, high-altitude, variable-speed, and "S" suffix variants. Whether you're servicing a BS500-4, a BS600S, or a BS700, part number is the factory-correct replacement for the crankcase assembly on your machine.
Key Features
- Factory-Correct Casting and Tolerances — Manufactured to OEM specifications, this crankcase maintains the precise bore alignment and wall integrity required to keep internal engine components properly seated and lubricated.
- Broad BS-Series Coverage — A single part number covering BS500, BS500S, BS600, BS600S, BS650, BS700, BS500-4, and BS600-4 vibratory rammers across multiple machine configurations and shoe sizes.
- Direct Bolt-On Replacement — Engineered to match OEM mounting points, gasket surfaces, and port locations, so the 5000112078 installs using existing hardware and sealing components without modification.
- Structural Integrity for High-Impact Operation — Vibratory rammers subject the engine block to continuous percussive load cycles. A genuine OEM crankcase resists cracking and distortion under these demanding conditions where inferior castings may fail prematurely.
- Fuel and Oil System Integrity — Correct crankcase sealing is critical to maintaining proper crankcase pressure, preventing fuel migration, and keeping oil where it belongs — a compromised crankcase can cause oil starvation and catastrophic engine failure.
The crankcase is the structural foundation of the rammer's two-stroke engine, housing the crankshaft, connecting rod, and the sealed crankcase chamber that pressurizes the fuel-air mixture during each compression stroke. On a vibratory rammer, the crankcase endures both the mechanical stress of the engine's combustion cycle and the constant shock loads transmitted through the rammer foot — making material quality and dimensional accuracy critical. A cracked, warped, or leaking crankcase will disrupt crankcase pressure, cause fuel and oil loss, and ultimately lead to engine seizure if left unaddressed.
