The Wacker Neuson 5100009684 Wm 80 Engine is a genuine OEM engine designed for the BS50, BS60, and BS70 series gasoline vibratory rammers. Sourced directly through Wacker Neuson's authorized parts program, this engine meets the exact specifications required for these machines. Verified fitment spans multiple BS-series configurations including BS50-2i, BS50-2plus, BS60-2plus, BS70-2i, and BS70-2plus variants — making it the correct replacement when the original powerplant needs to be swapped out entirely.
Key Features
- Genuine OEM Power Output Match — engineered to deliver the same displacement, compression, and fuel delivery characteristics as the original Wm 80 unit, ensuring the rammer cycles at the correct impact force and frequency.
- Drop-In Compatibility — mounting points, shaft dimensions, and fuel/ignition interfaces correspond directly to the BS50, BS60, and BS70 rammer frames for a straightforward engine swap.
- Broad BS-Series Coverage — confirmed fitment across BS50-2i, BS50-2plus (6in and 11in), BS60-2plus (11in), BS70-2i, and BS70-2plus (11in) models in both US and international configurations.
- Sustained Compaction Force — a properly functioning Wm 80 engine maintains consistent stroke rate and impact energy; a worn or seized engine causes loss of compaction force and uneven trench or soil preparation.
- Fuel System Integrity — as a complete engine assembly, the 5100009684 includes the combustion and fuel circuit components built to OEM tolerances, supporting correct air-fuel mixture and reliable starting in field conditions.
The Wm 80 is the dedicated small gasoline engine that powers the BS-series vibratory rammer, driving the eccentric mechanism that produces the rapid up-and-down impact strokes used to compact cohesive soils, clay, and trench backfill. Without a correctly functioning engine, the rammer cannot develop the impact energy needed to achieve proper soil density, leading to failed compaction and potential ground settlement. When the engine fails due to wear, mechanical damage, or internal seizure, replacing it with the correct OEM unit — like the 5100009684 — restores the machine to full rated performance.
