The Bomag 05660347 Tension Spring is a genuine OEM component designed for Bomag BW 115 and BW 131 tandem rollers as well as the BW 900-50 walk-behind / light roller. Sourced directly from Bomag, this tension spring matches the original equipment specification for a direct, hassle-free installation. It fits a wide range of tandem roller variants including the BW 115 AC-3, BW 115 AD-3, BW 115 AC-5, BW 131 ACW-2, BW 131 AD-2, BW 131 ACW-3, BW 131 AD-3, BW 131 AD-5, and BW 131 ACW-5, along with the BW 900-50 walk-behind / light roller — making part number 05660347 a versatile service item to keep on hand.
Key Features
- Genuine OEM Spring Tension Integrity — manufactured to the exact load and elongation characteristics Bomag specifies, so the spring delivers consistent return force rather than the inconsistent pull of a worn or non-OEM substitute.
- Direct Drop-In Replacement — engineered to the same hook geometry, free length, and wire diameter as the original, allowing installation without modification to mounting points or hardware.
- Broad Tandem and Walk-Behind Coverage — a single part number covers BW 115 AC-3, BW 115 AC-5, BW 131 ACW-2, BW 131 AD-2, BW 131 ACW-3, BW 131 AD-3, BW 131 AD-5, BW 131 ACW-5 tandem rollers, and the BW 900-50 walk-behind / light roller.
- Sustained Clamping and Return Performance — a properly tensioned spring maintains the clamping or return action it controls; a fatigued or broken spring leads to loose components, erratic operation, and accelerated wear on linked parts.
- Corrosion-Resistant Construction — finished to withstand the moisture, dust, and vibration exposure typical of compaction work, helping the spring maintain its rated tension through extended service intervals.
A tension spring stores mechanical energy when stretched and releases it to pull connected components back to their resting position. In compaction equipment, tension springs are commonly used to maintain pressure on levers, linkages, throttle controls, and safety mechanisms, ensuring those components return reliably to a neutral or engaged state after each actuation. When a tension spring loses its rated tension through fatigue, corrosion, or breakage, the mechanism it controls may respond sluggishly, fail to return fully, or disengage unexpectedly — compromising both the consistency of machine operation and operator confidence in the equipment.
