The Wacker Neuson 5100049230 is a genuine OEM Tension Spring designed for the BS-series gasoline vibratory rammer lineup, including the BS50-4As, BS60-4As, BS62-4A/28, BS65-4As, BS68-4A/28, BS70-4As, and BS72-4As models. As a factory-original component, the part is manufactured to the exact specification required by Wacker Neuson for proper rammer operation. This part covers a wide range of BS-series variants including US, CN, Sunbelt, and standard configurations, making it a versatile stocking replacement for service technicians and fleet operators. Confirm your machine model number before ordering to ensure compatibility with your specific unit.
Key Features
- Genuine OEM Spring Rate — Factory-original tension spec ensures the spring delivers the correct return force for consistent rammer stroke and compaction rhythm.
- Direct Drop-In Replacement — Engineered to install into existing mounting points on BS-series rammers without modification to the spring housing or retainer.
- Broad BS-Series Fitment — Compatible with BS50-4As, BS60-4As, BS62-4A/28, BS65-4As, BS68-4A/28, BS70-4As, and BS72-4As rammers across standard, US, CN, and Sunbelt variants.
- Sustained Stroke Performance — A properly tensioned spring maintains the rammer's cyclic impact energy, keeping compaction output consistent through trench and cohesive soil work.
- Fatigue-Resistant Construction — OEM spring material is selected to withstand the high-cycle stress of continuous rammer operation, resisting set and deformation over extended service life.
The tension spring in a vibratory rammer controls the rebound and return stroke of the percussion mechanism, working in sync with the engine's excitation system to maintain a steady, rhythmic impact cycle. When the spring is correctly tensioned, the rammer delivers uniform blows into cohesive soils and trench backfill, producing thorough compaction with each pass. A worn or broken tension spring disrupts the stroke cycle, causing erratic bouncing, reduced impact energy, and uneven compaction that can compromise the integrity of the compacted layer.
