- Confirmed Fitment — verified for BPR 45/55 D and BPR 55/65 D reversible vibratory plates, covering diesel-powered models in the BPR mid-range compaction lineup
- Consistent Engine Speed Control — a correctly tensioned governor spring holds engine RPM steady under load, delivering uniform compaction force and predictable plate performance
- OEM Part Number Accuracy — order with confidence using Bomag part number 05744985, matching the original component reference in the Bomag parts catalog
The governor spring is a critical component in the engine's mechanical speed-control system. It works against the centrifugal flyweights inside the governor assembly to maintain a set engine RPM — when fuel demand increases under load, the spring tension pulls the fuel rack open to compensate and keep the engine from bogging down. A worn, stretched, or broken governor spring causes erratic engine speed, surging, or an inability to hold a steady RPM under compaction load, which directly compromises plate output and compaction consistency. Replacing this spring restores precise speed regulation and ensures the BPR plate performs as intended across varying soil conditions.
