The Wacker Neuson 5100045479 is a genuine OEM Crankcase designed for the BS50-2plus, BS60-2plus, and BS70-2plus series vibratory rammers. As a direct OEM replacement, this crankcase is manufactured to the exact tolerances and material specifications of the original part — ensuring proper alignment of internal engine components and a secure, leak-free assembly. Fitment covers multiple configurations across the BS50-2plus, BS60-2plus, and BS70-2plus rammer families, including US, ha US, CN, and standard variants. When your rammer needs a crankcase replacement, sourcing the correct OEM part number 5100045479 ensures you restore the machine to full working condition without guesswork.
Key Features
- OEM-Spec Casting Integrity — Manufactured to original material and dimensional specs, maintaining proper bore alignment and sealing surfaces critical for a two-stroke rammer engine.
- Drop-In Engine Housing Replacement — Engineered to match original mounting points and port geometry, allowing internal components to seat and seal correctly during reassembly.
- Broad BS-Series Fitment — Covers BS50-2plus, BS60-2plus, and BS70-2plus rammers across US, ha US, CN, and standard configurations — confirm your machine number before ordering.
- Protects Internal Engine Components — A sound crankcase maintains the sealed environment that two-stroke rammer engines depend on for proper compression and lubrication; a cracked or damaged housing leads to pressure loss and accelerated wear.
- Fuel System Integrity Compliance — The crankcase forms part of the sealed fuel-air path in a two-stroke engine; using a correctly spec'd OEM housing prevents uncontrolled air leaks that can create unsafe running conditions.
The crankcase is the structural core of the rammer's engine, housing the crankshaft, bearings, and the sealed crankcase volume that two-stroke engines rely on for their intake and compression cycle. In a vibratory rammer like the BS-series, this component is subject to constant high-frequency impact loads as well as the internal pressures of the two-stroke combustion cycle. A cracked, warped, or damaged crankcase compromises the airtight seal required for correct fuel-air mixture delivery, leading to hard starting, loss of power, and potential seizure of internal components if left unaddressed.
