The Wacker Neuson Fly Wheel is a genuine OEM component designed for the BS50-4As, BS60-4As, BS65-4As, BS68-4A/28, BS70-4As, BS72-4As, and BS62-4Ab/28 series rammers. Sourced directly from Wacker Neuson, this fly wheel is manufactured to the same standards as the original part fitted at the factory, ensuring a direct, like-for-like replacement. It covers an extensive range of BS-series rammer configurations, including US, CN, and Sunbelt variants, making it a versatile solution across the lineup. Always confirm your model number before ordering to ensure correct application.
Key Features
- Genuine OEM Rotational Precision — Manufactured by Wacker Neuson to exact balance and mass specifications, ensuring smooth engine rotation and consistent compaction stroke timing.
- Direct Bolt-On Replacement — Engineered to match the original mounting interface on BS-series rammers, fitting without modification to existing engine housings and crankshaft assemblies.
- Broad BS-Series Compatibility — Fits BS50-4As, BS60-4As, BS62-4Ab/28, BS65-4As, BS68-4A/28, BS70-4As, and BS72-4As rammers across US, CN, and Sunbelt variants.
- Sustained Compaction Performance — A correctly functioning fly wheel maintains the energy storage needed to deliver consistent impact force; a worn or cracked fly wheel leads to irregular stroke rhythm and reduced compaction output.
- OEM Part Number Verified — Listed under Wacker Neuson part number 5100049216, giving you confidence that you are ordering the correct component for your specific machine.
The fly wheel is a rotating mass mounted to the engine crankshaft that stores kinetic energy between power strokes, keeping the engine running smoothly and delivering a steady, controlled impact force to the rammer foot. On a vibratory rammer, this energy storage is critical — it directly affects how consistently and powerfully the machine strikes the ground with each cycle. When a fly wheel is cracked, out of balance, or worn, the engine may run roughly, the compaction stroke becomes irregular, and the machine loses the striking force needed to properly compact soil or granular base material.
