- Confirmed Fitment — compatible with the BPR 40/45 D, BPR 40/45 D-2, and BPR 40/45 D-3 reversible vibratory plates
- Stable Engine RPM Under Load — a correctly tensioned governor spring keeps engine speed steady as compaction load varies, delivering consistent vibratory output and compaction depth pass after pass
- Verified Part Number — order with confidence using Bomag part number 05744598 to confirm you are receiving the correct spring for your machine
The governor spring is a critical component within the mechanical engine governor, applying the return force that works against centrifugal flyweights to regulate engine speed. When the spring tension is correct, the governor holds a stable RPM under changing loads — essential for predictable compaction performance on BPR 40/45 D series reversible vibratory plates. A worn, stretched, or broken governor spring causes erratic engine speed, hunting at idle, or an inability to hold full throttle, all of which directly compromise compaction quality and can accelerate engine wear.
