The Wacker Neuson Cylinder Spring is a genuine OEM component designed for the BS50-2, BS50-4As, BS65-4As, AS50e, and AS60e series rammers. Sourced directly from Wacker Neuson, this part meets the exact specifications of the original spring installed at the factory. It is compatible across a wide range of BS and AS rammer configurations, including US-market, standard, and heavy-application variants. If your rammer is losing impact energy, cycling inconsistently, or failing to return properly, the cylinder spring is a common wear item to inspect and replace.
Key Features
- Genuine OEM Spring Rate: — Manufactured to the original tension and compression specification, ensuring the cylinder cycles with the correct force and rhythm for consistent soil compaction.
- Drop-In Replacement: — Engineered to the same dimensions as the original, fitting directly into the cylinder assembly of compatible BS and AS series rammers without modification.
- Broad Rammer Compatibility: — Fits BS50-2, BS50-4As, BS65-4As, AS50e, and AS60e models across multiple configurations, including 6-inch, 10-inch, 11-inch, and heavy-application variants.
- Consistent Impact Energy: — A correctly functioning cylinder spring maintains the rammer's stroke rhythm, delivering full compaction force on every blow — critical for trench backfill and cohesive soil work.
- Genuine Wacker Neuson Quality: — Backed by Wacker Neuson's OEM standards, this spring is built from materials selected specifically for the fatigue demands of high-cycle rammer operation.
The cylinder spring is a core component of a rammer's percussion mechanism. It stores and releases energy within the cylinder assembly to drive the rammer foot downward with each stroke, then allows the foot to rebound and repeat the cycle. When the spring weakens or breaks, the rammer loses striking force, the stroke becomes erratic, or the machine stops cycling altogether — directly impacting compaction quality and job progress. Replacing a worn spring with the correct OEM part restores the machine to its intended performance.
