The Bomag 05728273 Spiral Spring is a genuine OEM component designed for Bomag BP-series vibratory plates and BPR-series reversible vibratory plates, including the BPR 25/40 D, BPR 35/60 D, BP 15/45, BP 25/48 D, BPR 50/55 D, BPR 60/65 D, and a wide range of additional models across both families. Sourced directly from Bomag, this spiral spring carries the same part number, material spec, and dimensional tolerances as the component installed at the factory. This genuine OEM part is a direct drop-in replacement, eliminating guesswork and ensuring the exciter assembly returns to correct operating condition. Confirm compatibility using part number 05728273 against your machine's serial plate before ordering.
Key Features
- Genuine OEM Spring Rate — manufactured to Bomag's exact coil geometry and spring-rate specification, maintaining the correct tension and energy transfer within the exciter system
- Direct Drop-In Replacement — matches the original mounting geometry of both BP-series vibratory plates and BPR-series reversible vibratory plates for straightforward installation
- Broad Fitment Coverage — fits a wide range of Bomag compaction plates including the BPR 25/40 D, BPR 40/45 D, BPR 35/42 D, BPR 35/60 D, BPR 40/60 D, BPR 50/55 D, BPR 60/65 D, BP 15/45, BP 15/45 D-2, BP 18/45 D-2, BP 20/45 D, BP 20/50 D, BP 25/48 D, BP 25/50 D, BPR 25/45 D-3, BPR 25/50 D, BPR 30/38 D-3, BPR 40/45 D-2, BPR 40/45 D-3, BVP 18/45 D, and additional variants
- Exciter System Integrity — a fatigued or broken spiral spring disrupts vibration output and compaction force; replacing it with this OEM part restores consistent plate performance across all soil and asphalt applications
- Verified Part Number — order with confidence using Bomag part number 05728273 to ensure you receive the exact spring for your machine
The spiral spring in a vibratory plate compactor sits within the exciter housing and plays a key role in controlling the oscillating motion of the eccentric weight assembly. It stores and releases energy in a precise, repeating cycle that generates the plate's compaction force and frequency. When this spring weakens, cracks, or breaks, the plate loses consistent vibration output — compaction depth drops, surface coverage becomes uneven, and continued operation risks further damage to the exciter unit. Replacing a worn spiral spring with a correct OEM part restores the machine's rated compaction performance and protects the surrounding exciter components from the stress of an unbalanced or erratic vibration cycle.
