The Wacker Neuson Throttle Return Spring is a genuine OEM component designed for the BS50-2, BS60-2, BS70-2, and BS65-V series vibratory rammers, as well as BH40, BH55, and BH65 series gasoline breakers. This spring ensures the throttle mechanism snaps back to its rest position consistently after each operator input, maintaining proper engine speed control throughout the working cycle. As a direct OEM replacement, part is manufactured to the same specification as the original, covering an extensive range of two-cycle and oil-injected rammer variants across both standard and EU-configured machines.
Key Features
- OEM Spring Tension Spec: — Manufactured to the original coil tension rating so throttle return force and travel distance match the factory mechanism exactly.
- Drop-In Throttle Linkage Fit: — Designed to seat directly into the existing throttle linkage anchor points on covered BS-series rammers and BH-series breakers without reworking the carburetor assembly.
- Broad BS and BH Series Coverage: — Confirmed fitment across BS50-2, BS50-2i, BS60-2, BS60-2i, BS65-V, BS70-2, BS70-2i, BH40, BH55, BH65, and MS52/MS62 rammer variants, including EU-configured models.
- Consistent Throttle Snap-Back: — A fully functional return spring keeps the throttle from sticking in a partially open position, which can cause erratic engine speed and uncontrolled ramming force.
- Fuel System Safety Relevance: — A failed or stretched throttle return spring can leave the engine running above idle when the operator releases the control handle; replacing it promptly restores proper throttle closure and safe engine response.
The throttle return spring is a small but operationally critical component in the carburetor throttle linkage of a gasoline rammer or breaker. Its job is to pull the throttle plate or slide back to the idle or closed position the moment the operator releases the throttle trigger or lever. When the spring weakens, stretches, or breaks, the engine may hang at elevated RPM, fail to return to idle cleanly, or respond unpredictably to throttle input — all of which affect both operator control and machine safety. Replacing a worn spring restores the crisp, predictable throttle response that keeps the machine behaving as intended during compaction or demolition work.
