The Bomag 05740262 Valve Spring is a genuine OEM component designed for Bomag BW 80 AD-2, BW 90 AD-2, BW 100 ADM-2, BW 80 ADS, and BW 90 AC-2 tandem rollers. As a direct OEM part, this valve spring meets the exact tensile and dimensional specifications Bomag engineers set for these machines. Sourced directly from Bomag, part number 05740262 ensures a correct, catalog-verified match for the engine valvetrain on these tandem roller models. Keeping the valvetrain running to spec is critical for consistent engine output and long service life on your compaction equipment.
Key Features
- OEM Spring Rate Accuracy — manufactured to Bomag's exact load and tension specifications, ensuring proper valve seating pressure for the engine fitted to these tandem rollers
- Direct OEM Replacement — installs directly into the valvetrain in place of the original spring, with no modification to retainers, keepers, or valve stems required
- Broad Tandem Roller Coverage — fits BW 80 AD-2, BW 90 AD-2, BW 100 ADM-2, BW 80 ADS, and BW 90 AC-2 tandem rollers under a single verified part number
- Consistent Valve Closure Force — a correctly tensioned spring holds valves firmly shut at rated compression, protecting combustion efficiency and engine performance during heavy compaction work
- Catalog-Verified Part Number — sourced as genuine Bomag OEM, so the specification, material grade, and free length are exactly what the original design calls for
A valve spring holds each intake or exhaust valve firmly against its seat after the camshaft lobe passes, sealing the combustion chamber at the right moment in the engine cycle. If a valve spring loses tension, cracks, or breaks, the affected valve may not close fully or quickly enough, leading to compression loss, rough running, increased fuel consumption, and potential valve or seat damage. On tandem rollers like the BW 80 AD-2 and BW 100 ADM-2 — where sustained engine load during asphalt compaction is the norm — a fatigued or failed valve spring can quickly escalate from a performance issue into a costly engine repair.
