The Bomag 05747345 Valve Spring is a genuine OEM component designed for a wide range of Bomag vibratory plates and the BW 55 E walk-behind roller. Sourced directly from Bomag, this valve spring meets the original engineering specification for correct tension, travel, and seating — ensuring the engine's valvetrain operates exactly as designed. This part is confirmed to fit forward vibratory plates across the BP and BVP families, reversible vibratory plates across the BPR family, and the BW 55 E, covering models including the BP 10/30, BP 20/50, BP 25/50, BPR 25/40, BPR 30/38, BPR 35/60 H, BVP 10/36, BVP 18/45, and many more in this series.
Key Features
- Genuine OEM Spring Rate — manufactured to Bomag's original tension and load specifications, maintaining precise valve timing and consistent compression across the engine's service life
- Direct-Fit Replacement — matches the original seat diameter, free length, and coil geometry for drop-in installation with no machining or adaptation
- Broad Fitment Coverage — confirmed fit for BP, BVP, and BPR vibratory plate families, including the BP 12/50 A, BP 23/60, BPR 25/50, BPR 30/38-3, and BVP 12/50 A, plus the BW 55 E walk-behind roller
- Valvetrain Integrity — a correctly rated valve spring keeps intake and exhaust valves fully seated at the right moment; a weak or broken spring causes poor compression, misfires, and loss of compaction output
- Fuel System Safety — proper valve seating prevents combustion gases from bypassing the chamber, protecting the engine from thermal damage and keeping exhaust emissions within expected operating parameters
A valve spring holds the engine's intake and exhaust valves closed against combustion pressure, returning each valve to its seat after the camshaft lobe passes. Without the correct spring tension, valves can float at higher RPMs, fail to seat fully, or allow compression to bleed past the valve face — resulting in hard starting, rough running, and reduced engine power. On vibratory plate compactors and light rollers, where the engine works under constant load, a fatigued or broken valve spring will cause a noticeable drop in centrifugal force output and can lead to accelerated wear on valve seats and guides if left unaddressed. Replacing a worn spring with a genuine Bomag part number 05747345 restores the correct valvetrain dynamics and protects the rest of the engine from secondary damage.
