The Wacker Neuson Spring is a genuine OEM Spring designed for the BS50-4As, BS60-4As, BS70-4As, BS62-4Ab/28, BS65-4As, BS68-4A/28, BS72-4As, and related 11-inch and 28-series rammer models. Sourced directly from Wacker Neuson, this part matches the original specification exactly, ensuring it seats, tensions, and performs the same way as the part it replaces. Broad fitment coverage spans multiple BS-series rammer variants including US, CN, and Sunbelt configurations. Keep a verified OEM part on hand and get your rammer back to work without guesswork.
Key Features
- Genuine OEM Spring Tension: — Manufactured to the original load and deflection specification, so the spring delivers consistent energy transfer within the rammer mechanism — not an approximation.
- Direct Drop-In Replacement: — Engineered to the same dimensions and end configuration as the original, fitting into the existing spring pocket without modification to mounts or retainers.
- Wide BS-Series Fitment: — Compatible with a broad range of Wacker Neuson BS50-4As, BS60-4As, BS62-4Ab/28, BS65-4As, BS68-4A/28, BS70-4As, and BS72-4As rammer variants.
- Consistent Compaction Output: — A correctly tensioned spring maintains the rammer's stroke rhythm and impact frequency; a worn or weakened spring causes erratic compaction and reduced ground penetration.
- Authorized OEM Part: — Part number 5100049181 is an authorized Wacker Neuson component, giving you full confidence in traceability and parts compatibility across your fleet.
The spring in a rammer plays a central role in the percussion cycle — it stores and releases energy to drive the foot downward with each stroke, working in coordination with the engine and internal drive components to produce the rapid, focused impacts that compact soil and granular fill. When the spring loses tension or breaks, the rammer loses compaction force, the stroke becomes inconsistent, and the machine may stop functioning altogether. Replacing a worn spring promptly with a correctly rated OEM part restores the intended stroke energy and protects the surrounding drive components from the added stress caused by a failing part.
