The Bomag 05723032 Governor Spring is a genuine OEM component designed for a range of Bomag walk-behind light rollers, reversible vibratory plates, and trench compactors. Sourced directly from Bomag, this governor spring meets the exact specifications required to maintain proper engine speed regulation across compatible machines. This part fits the BW 60 S, BW 65 HS, BW 65 S, BW 75 E, BW 75 S walk-behind light rollers, the BPR 50/55 D reversible vibratory plate, and the BW 35 and BW 35 W trench compactors. When your existing spring weakens or fails, swapping in part number 05723032 restores proper throttle response and engine control.
Key Features
- Genuine OEM Spring Tension — manufactured to Bomag's original tension specification, ensuring the governor operates within the correct engine speed range for this engine family
- Direct Drop-In Replacement — engineered to the same dimensions and hook geometry as the original, connecting to existing governor linkage without modification
- Broad Bomag Fitment — covers BW 60 S, BW 65 HS, BW 65 S, BW 75 E, and BW 75 S walk-behind light rollers, the BPR 50/55 D reversible vibratory plate, and BW 35 and BW 35 W trench compactors
- Stable Engine Speed Control — a properly tensioned governor spring keeps engine RPM consistent under load, protecting machine performance and preventing erratic throttle behavior
- Fuel System Safety — a fatigued or broken governor spring can cause uncontrolled engine over-speed; replacing it with a genuine part restores safe operating limits
The governor spring is a critical link in the engine's speed-regulating system. It works against the centrifugal force of the governor flyweights to maintain a set engine RPM, ensuring the machine delivers steady, controlled compaction power regardless of load. When this spring weakens, stretches, or breaks, the engine may surge, hunt for speed, or lose the ability to hold a steady throttle — conditions that reduce compaction effectiveness and can accelerate wear on other engine components.
