The Bomag 05715781 Governor Spring is a genuine OEM component designed for the BW 75 ADL and BW 75 AD walk-behind light rollers. Sourced directly from Bomag, this governor spring meets the exact specifications of the original part it replaces, ensuring consistent engine speed response and smooth throttle control on your machine. This part is a direct fit for BW 75 ADL and BW 75 AD models, making it the correct choice when servicing your roller's engine governor assembly.
Key Features
- Genuine OEM Spring Tension — manufactured to Bomag's original tension rating, so the engine governor responds accurately across the full throttle range without hunting or surging
- Direct Replacement Fit — engineered to install into the governor assembly of BW 75 ADL and BW 75 AD walk-behind light rollers without modification, using part number 05715781 for verified ordering accuracy
- Confirmed Model Coverage — fits the BW 75 ADL and BW 75 AD walk-behind light rollers, covering both variants in the BW 75 series
- Restored Engine Speed Stability — a worn or broken governor spring causes erratic engine RPM, rough idling, and loss of compaction consistency; replacing it restores steady, controllable machine operation
- Long-Term Durability — produced from the same materials and to the same tolerances as the original, this spring resists fatigue and maintains proper tension through demanding compaction cycles
The governor spring is a small but critical component in the engine's mechanical speed-control system. It applies calibrated tension to the governor mechanism, which regulates fuel delivery and keeps engine RPM steady under varying load conditions. When this spring weakens, loses tension, or breaks, the governor can no longer hold a consistent speed — resulting in engine surging, unstable idling, and reduced compaction performance on the roller. Replacing it with the correct OEM spring is the straightforward fix that restores proper throttle response and engine stability.
