Key Features
- Genuine OEM Throttle Linkage Spec — manufactured by Bomag to the exact dimensional and material tolerances required for consistent governor response across the BW roller lineup
- Direct Drop-In Replacement — connects to the existing governor linkage assembly without reworking mounting points or adjacent hardware
- Broad BW-Series Coverage — fits single drum rollers including BW 142 D-2, BW 145 D-3, BW 145 DH-3, BW 177 D-4, BW 177 DH-4, BW 177 DHC-4, BW 179 DH-4, and BW 179 DHC-4, as well as tandem rollers including BW 141 AD-2, BW 141 AD-4, BW 144 AD-2, BW 151 AD-2, BW 151 AD-4, BW 154 AD-2, BW 154 AD-4, BW 161 AD-4, BW 161 AC-4, BW 161 ADO-4, and additional variants
- Engine Speed Stability — a correctly functioning governor rod maintains steady engine RPM under load, protecting compaction consistency and preventing over-revving or hunting
- Verified Part Number Fit — part number 05712239 cross-referenced to Bomag's OEM catalog, so you order with confidence and avoid costly mis-shipments
The governor rod is a mechanical linkage component that connects the throttle control input to the engine's fuel delivery governor. It transmits operator throttle commands and governor corrections to regulate engine speed, ensuring the engine holds a consistent RPM under varying compaction loads. When the governor rod is bent, worn, or disconnected, the engine may surge, hunt for speed, or fail to hold steady RPM — all of which compromise drum vibration frequency, compaction quality, and overall machine control. Replacing a damaged rod with a genuine Bomag part restores precise throttle response and stable power delivery.
