The Wacker Neuson Crankcase 2-Stroke is a genuine OEM component designed for the BS50-2plus, BS60-2plus, and BS70-2plus series rammers. Sourced directly from Wacker Neuson, this crankcase is manufactured to the same specifications as the original part, ensuring a correct, hassle-free installation. Fitment covers both standard and heavy-duty US-spec variants across the BS50-2plus, BS60-2plus, and BS70-2plus lines, including 6-inch and 11-inch shoe configurations.
Key Features
- OEM-Grade Structural Integrity — Cast and machined to original tolerances, maintaining the precise bearing bore and sealing surfaces critical for a 2-stroke crankcase.
- Direct Drop-In Replacement — Matches all original mounting points, port alignments, and gasket mating surfaces for a straightforward swap without rework.
- Broad Rammer Compatibility — Fits BS50-2plus, BS60-2plus, and BS70-2plus series rammers, covering standard, heavy-duty, US-spec, and CN variants.
- Protects Engine Internals — A sound crankcase maintains proper oil mist lubrication and compression integrity; a cracked or warped housing leads to rapid bearing failure and loss of power.
- Fuel System Sealing — Correct port geometry and sealing surfaces prevent air leaks that would disrupt the 2-stroke fuel-air charge and cause hard starting or erratic performance.
The crankcase is the structural core of a 2-stroke engine, housing the crankshaft, bearings, and the sealed chamber that drives the fuel-air transfer process essential to 2-stroke operation. On a rammer like the BS50-2plus through BS70-2plus series, it also absorbs the constant vibration loads generated during soil compaction, making material integrity and dimensional accuracy critical. When the crankcase cracks, warps, or develops seal failures, compression drops, bearings lose lubrication, and the engine will typically run rough, lose output, or fail to start altogether.
