The Wacker Neuson is a genuine OEM Gas Engine GXR120RT-KR-WN-SD Stage V designed for the BS-4As series gasoline vibratory rammers, including the BS50-4As, BS60-4As, BS65-4As, BS70-4As, BS72-4As, and related variants. As a direct factory replacement engine, part number is built and validated to the exact configuration Wacker Neuson specifies for this rammer family. This Stage V-compliant powerplant ensures your rammer meets current emissions standards without any compromise to compaction output or run-time performance.
Key Features
- Stage V Emissions Compliance — Honda GXR120RT-KR-WN-SD engine meets Stage V emissions regulations, keeping your equipment legal for operation in regulated markets and on emission-controlled jobsites.
- Genuine OEM Engine Assembly — Sourced directly from Wacker Neuson, this engine is matched to the exact displacement, output curve, and mounting specification required by the BS-4As rammer platform — no guesswork on fitment.
- Wide BS-4As Series Coverage — Confirmed fitment across BS50-4As, BS60-4As, BS65-4As, BS70-4As, and BS72-4As models in both standard and US-market configurations.
- Full Compaction Power Restored — A worn or seized engine robs the rammer of the impact energy needed to compact cohesive soils and trench backfill effectively; this replacement restores full rated blow rate and impact force.
- Direct Drop-In Configuration — The GXR120RT-KR-WN-SD designation confirms this engine ships in the exact Wacker Neuson-specific build, including correct shaft, throttle, and mounting interface for the BS-4As crankcase.
The gas engine is the core power source of the BS-4As vibratory rammer, converting fuel combustion into the rapid reciprocating motion that drives the rammer's foot into cohesive and granular soils. In trench compaction and tight-space applications, consistent engine output is critical — the rammer must deliver a precise number of blows per minute to achieve the required soil density at depth. When the engine loses power, fails to start, or no longer runs cleanly, compaction quality becomes unpredictable and the machine is effectively out of service. Replacing the engine with the correct Wacker Neuson 5100058517 assembly restores the rammer to full operating specification and ensures it continues to perform as engineered.
