The Wacker Neuson 5100040147 is a genuine OEM Compression Spring designed for DS70 diesel rammers and BS62-4A/28 and BS68-4A/28 gasoline vibratory rammers. Sourced directly from Wacker Neuson, this part meets the exact specifications required for proper spring tension and rammer cycle performance across the supported machine configurations, including Sunbelt and CN variants. The 5100040147 installs as a direct replacement with no guesswork — part number verification against your machine's serial number is always recommended before ordering.
Key Features
- Correct Spring Rate for Rammer Applications — Engineered to the precise tension specification required to sustain consistent impact energy and stroke cycle in Wacker Neuson jumping jack rammers.
- Genuine OEM Part — Manufactured to Wacker Neuson's original design tolerances, ensuring the spring performs as intended within the rammer's drive mechanism.
- Broad Rammer Family Coverage — Compatible with DS70 diesel rammers and BS62-4A/28 and BS68-4A/28 gasoline rammers, including standard, Sunbelt, and CN configurations.
- Sustains Impact Cycle Consistency — A worn or fatigued compression spring causes irregular stroke rhythm, reduced compaction force, and accelerated wear on surrounding drive components.
- Direct OEM Replacement — Replaces the original spring on a drop-in basis, restoring the rammer's designed compaction output without modification to adjacent components.
The compression spring in a vibratory rammer is a critical component in the machine's exciter mechanism, storing and releasing energy to drive the repeating impact stroke that compacts cohesive soil in trenches and tight spaces. It works in coordination with the piston and drive train to maintain a steady, controlled bounce cycle — the foundation of effective trench compaction. When the spring weakens, loses tension, or breaks, the rammer loses stroke consistency, compaction output drops noticeably, and the added stress can damage surrounding components if left unaddressed.
