The Bomag 05744330 Governor Spring is a genuine OEM component designed for Bomag reversible vibratory plates, vibratory plates, tampers, and walk-behind rollers. This governor spring is a direct OEM replacement sourced from Bomag, ensuring the correct spring rate and dimensions for proper throttle governor operation. Compatible fitment spans the BPR 30/38 D, BPR 30/38 D-2, BPR 30/38 D-3, BPR 40/45 D, BPR 40/45 D-2, BPR 40/45 D-3, BPR 50/52 D, BPR 50/52 D-2, BPR 50/52 D-3, BP 15/45 D, BP 15/45 D-2, BP 18/45 D-2, BT 80 D, and BW 75 H. Using part number 05744330 guarantees you are installing the exact spring Bomag specifies for these machines, eliminating guesswork on cross-compatibility.
Key Features
- Genuine OEM Spring Rate — manufactured to Bomag's exact tension specification, ensuring the governor responds correctly across the engine's RPM range for consistent compaction output
- Direct-Fit Replacement — matches the original hook dimensions and coil geometry for a drop-in installation with no modifications to the governor linkage
- Broad Equipment Coverage — fits BPR-series reversible vibratory plates, BP-series vibratory plates, the BT 80 D tamper, and the BW 75 H walk-behind roller, including multiple generation variants (D, D-2, D-3)
- Stable Engine Speed Control — a properly tensioned governor spring holds the set engine speed under load, preventing RPM surges or hunting that reduce compaction effectiveness and increase fuel consumption
The governor spring is a key component in the mechanical engine speed governor found on diesel-powered compaction equipment. It works in tension against the flyweights in the governor assembly, maintaining the target engine RPM set by the operator. When the spring weakens, stretches, or breaks, the engine loses the ability to hold a steady speed — resulting in RPM hunting, surging at idle, or an inability to reach full operating speed under load. Replacing a worn governor spring with the correct Bomag 05744330 unit restores stable engine control and ensures the machine delivers consistent compaction force across every pass.
