The Bomag 05740211 Governor Spring is a genuine OEM component designed for Bomag BW 80, BW 90, and BW 100 series tandem rollers. Sourced directly from Bomag, this spring carries the exact specifications required to restore proper governor function and engine speed regulation. This Governor Spring is confirmed to fit a wide range of tandem roller variants, including the BW 80 AD-2, BW 90 AD-2, BW 100 ADM-2, BW 80 ADS, BW 90 AC-2, BW 100 SCC-5, BW 80 AD-5, BW 90 AD-5, BW 100 ADM-5, BW 90 SC-5, BW 100 SC-5, BW 100 ACM-5, BW 90 AC-5, BW 90 SL-5, BW 90 SL-5 CC, and BW 100 SLM-5. Ordering by part number 05740211 ensures you receive the correct spring for your machine without guesswork.
Key Features
- Genuine OEM Spring Tension — manufactured to Bomag's exact load and rate specification, ensuring the governor responds accurately across the full engine speed range
- Drop-In Replacement — engineered to the original spring geometry, allowing direct installation in place of the worn or broken component with no modification to the governor assembly
- Broad Tandem Roller Coverage — fits BW 80, BW 90, and BW 100 series tandem rollers including AD-2, AD-5, AC-2, AC-5, SC-5, SCC-5, SL-5, SL-5 CC, ADM-2, ADM-5, ACM-5, ADS, and SLM-5 variants
- Consistent Engine Speed Control — a correctly tensioned governor spring keeps engine RPM stable under varying compaction loads, directly supporting smooth drum operation and consistent mat quality
- Fuel System Compliance — precise spring tension is critical to maintaining correct fuel delivery limits; a fatigued or broken spring can cause over-fueling, erratic throttle response, or engine runaway, making timely replacement an important safety measure
The governor spring is a small but critical component within the engine's mechanical governor assembly. It works against centrifugal flyweights to maintain a set engine speed, allowing the governor to balance fuel delivery with load demand. When the spring fatigues, loses tension, or breaks, the engine may hunt, surge, run at incorrect speeds, or become difficult to control — all of which affect compaction quality and safe machine operation. Replacing a worn Governor Spring with a correct OEM part restores the precise calibration the governor needs to function as intended.
