The Bomag 05747114 Governor Spring is a genuine OEM component designed for BP 10/36 and BP 15/45 vibratory plates and the BW 55 E walk-behind roller. Sourced directly from Bomag, this governor spring meets the same specifications as the part originally installed at the factory, ensuring correct engine speed regulation across all compatible machines. This part is a direct replacement for worn or broken springs and confirms fitment for the BP 10/36, BP 15/45, and BW 55 E.
Key Features
- Genuine OEM Spring Tension Accuracy — manufactured to exact tension and free-length specifications, ensuring the governor responds correctly across the engine's operating range
- Direct Replacement Fit — installs in place of the original spring with no alteration needed, using the same hook geometry and spring rate as the factory component
- Confirmed Compatibility — fits BP 10/36 and BP 15/45 vibratory plates and the BW 55 E walk-behind roller, covering both compact plate and light roller applications
- Stable Engine Speed Control — a properly tensioned governor spring holds consistent RPM under varying load, protecting engine performance and compaction output
- Fuel System Safety Integrity — a fatigued or broken governor spring can cause uncontrolled engine speed fluctuation; replacing it with a genuine OEM part restores safe throttle behavior
The governor spring is a critical component in the mechanical fuel governor system, responsible for applying the return force that balances centrifugal flyweight action and sets the engine's target RPM. When the spring is correctly tensioned, the engine maintains steady speed under load — essential for consistent compaction force on vibratory plates and smooth drum operation on walk-behind rollers. A fatigued, stretched, or broken governor spring causes erratic RPM, poor compaction performance, and potential over-revving, making prompt replacement important for both machine longevity and operator safety.
