The Wacker Neuson Throttle Return Spring is a genuine OEM component designed for the BS50-2, BS60-2, and BS70-2 series vibratory rammers, including two-cycle, oil-injected, variable speed, and high-altitude variants. As a direct factory replacement, this spring restores the throttle linkage to its correct operating behavior across the full range of BS-series rammers. Wacker Neuson's genuine OEM designation means is manufactured to the same specification as the original part — no guesswork on fitment or function. Compatible models span the BS500, BS600, BS650, BS700, BS50-2, BS60-2, and BS70-2 lines, covering a wide range of shoe sizes and engine configurations.
Key Features
- Correct Spring Rate for Throttle Control — Engineered to the OEM tension specification so the throttle snaps back fully and consistently with every release, maintaining predictable engine response.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, part number 5000118383 matches the original component exactly in material grade, coil geometry, and hook configuration.
- Broad BS-Series Compatibility — Fits BS50-2, BS60-2, BS70-2, BS500, BS600, BS650, and BS700 rammers across two-cycle, oil-injected, variable speed, and high-altitude configurations.
- Restores Safe Throttle Return Function — A failed or stretched throttle return spring prevents the engine from returning to idle when the operator releases the throttle — a condition that directly affects operator control on the worksite.
- Drop-In Replacement — Installs in the same position as the original spring with no modification to the throttle linkage assembly required.
The throttle return spring is a small but critical component in the rammer's engine control system. Its job is to pull the throttle linkage back to the idle position the moment the operator releases pressure — without it, the engine will not return to idle on its own, leaving the machine running at an uncontrolled speed. Over time, the spring can stretch, fatigue, or break entirely due to the constant vibration inherent to rammer operation, causing sluggish or absent throttle return. Replacing a worn spring promptly keeps the throttle responding as intended and ensures the operator maintains full control of the machine.
