The Wacker Neuson Governor Spring is a genuine OEM Governor Spring designed for the BS50-4As, BS60-4As, and BS70-4As series vibratory rammers. As a direct OEM replacement, this spring is sourced from Wacker Neuson and built to the exact specification required for correct engine speed regulation across all covered models. Fitment spans multiple configurations within the BS-4As rammer series, including 280 mm and 11-inch shoe variants sold in both US and international markets. When you need the correct part the first time, the is the authoritative choice.
Key Features
- OEM Spring Tension Spec — Manufactured to the precise tension rating required for correct governor function on Wacker Neuson 4-stroke rammer engines, ensuring the spring performs exactly as the original design demands.
- Drop-In Replacement — Installs directly into the governor assembly without modification, matching the original mounting points and hook geometry of the BS-4As engine platform.
- Broad BS-4As Series Coverage — Fits BS50-4As, BS60-4As, and BS70-4As rammers across 280 mm and 11-inch shoe configurations, covering a wide range of Wacker Neuson rammer fleets in a single part number.
- Consistent Engine Speed Control — A correctly tensioned governor spring keeps engine RPM stable under load, allowing the rammer to deliver consistent impact energy and predictable compaction output on every pass.
- Genuine Wacker Neuson Part — Supplied as a genuine OEM component, meaning material grade, coil geometry, and free length match the original part exactly — no guesswork on spring rate or fitment.
The governor spring is a small but critical component in the engine's speed-governing system. It works against centrifugal force generated by the governor flyweights to regulate throttle position and maintain a stable engine speed regardless of load changes. When the governor spring weakens, stretches, or breaks, the engine loses the ability to hold a consistent RPM — symptoms include hunting, surging, or the engine running at uncontrolled speeds, all of which directly affect compaction performance and can lead to accelerated engine wear. Replacing a worn or failed governor spring with the correct OEM part restores proper speed regulation and keeps the rammer operating within its intended performance range.
