The Wacker Neuson Spring is a genuine OEM component designed for the BS50-4As, BS60-4As, and BS70-4As vibratory rammer series. Sourced directly from Wacker Neuson, this spring matches the exact specifications of the original part, ensuring a correct, trouble-free installation. Compatibility extends across multiple configurations within the BS-4As rammer family, including 11-inch plastic shoe variants, high-altitude models, and hour-meter-equipped units. Whether you're returning a rammer to service or completing a scheduled rebuild, part number is the verified OEM replacement to reach for.
Key Features
- OEM-Spec Tension and Geometry — Manufactured to Wacker Neuson's original spring rate and dimensional tolerances, so compression and rebound characteristics stay consistent with the machine's designed operating cycle.
- Drop-In Installation — Engineered to the same profile and end configuration as the original, allowing direct installation without reworking mounting points or adjacent hardware.
- Broad BS-4As Series Coverage — Fits BS50-4As, BS60-4As, and BS70-4As rammers across 11-inch plastic shoe, high-altitude, and hour-meter configurations, covering a wide range of current production and recent serial number variants.
- Consistent Impact Energy Output — A correctly tensioned spring keeps the rammer's percussion mechanism working at the rated blow frequency; a worn or broken spring reduces compaction force and leads to uneven soil consolidation.
- Genuine Wacker Neuson Part — Supplied as an authorized OEM component, meaning the part number, material grade, and quality checks align with what left the factory originally.
The spring in a vibratory rammer is a core element of the percussion drive system, storing and releasing energy with each stroke to sustain the rhythmic impact that compacts soil and granular base materials. It works in coordination with the engine-driven exciter mechanism to maintain a consistent blow rate — the figure that determines how effectively the machine densifies material beneath the shoe. When a spring loses tension, cracks, or breaks, blow energy drops off noticeably, compaction depth becomes inconsistent, and the rammer may vibrate erratically or stall under load. Replacing a fatigued spring with a correctly rated OEM component restores the machine to its specified performance and protects the surrounding drivetrain components from the stress of an unbalanced percussion cycle.
