Order part number 05718381 with confidence — it is the same component that left the factory.
Key Features
- Genuine OEM Spring Rate — manufactured to Bomag's original load and extension specification, so tension is consistent and predictable across the service life of the spring
- Direct-Fit Replacement — matches the original hook style, coil diameter, and free length so this tension spring seats correctly in the existing mounts without rework
- Broad Model Coverage — fits BW 124 DH-4, BW 124 PDH, BW 124 DH-40, BW 124 PDH-40, BW 135 AD, BW 138 AD, BW 138 AC, BW 177 D-4, BW 124 PDH-40, and C815D rollers, including both single drum and tandem configurations
- Consistent Return Force — a correctly tensioned spring keeps the linked mechanism returning to its set position every cycle; a fatigued or broken spring causes inconsistent operation and accelerated wear on connected components
- Corrosion-Resistant Construction — OEM spring material holds up to the moisture, vibration, and temperature cycling that compaction equipment experiences in daily field use
A tension spring stores and releases mechanical energy to pull a component back to its resting or neutral position after it has been displaced. In compaction rollers, tension springs are commonly used in throttle linkages, safety interlock systems, and control mechanisms where a consistent return force is required to maintain predictable machine behavior. When a tension spring weakens through fatigue or breaks entirely, the affected linkage or control may fail to return properly, leading to sluggish response, unintended engagement, or accelerated wear on surrounding parts. Replacing a worn spring promptly with the correct OEM part restores the designed return force and keeps the linked system operating as intended.
