The Bomag 08820112 Valve Spring is a genuine OEM component designed for a wide range of Bomag single drum rollers, tandem rollers, and pneumatic tyred rollers. This valve spring delivers the correct tension and dimensional spec required to maintain proper valve train operation across compatible BW-series machines. Confirmed fitment includes BW 211 D-5, BW 211 DH-5, BW 211 PD-5, BW 211 PDH-5, BW 212 D-5, BW 212 DH-5, BW 213 D-5, BW 214 D-5, BW 174 AP-5, BW 161 AD-5, BW 190 AD-5, BW 202 AD-5, BW 28 RH, and additional BW-series variants. Sourced directly from Bomag, part number 08820112 is built to the same specification as the original component your machine left the factory with.
Key Features
- Genuine OEM Spring Tension — manufactured to Bomag's exact load and free-length specifications, ensuring correct valve seating force for consistent engine performance
- Direct Drop-In Replacement — engineered to the same dimensions as the original, this valve spring seats and retains with no rework to existing valve train hardware
- Broad BW-Series Coverage — fits BW 211, BW 212, BW 213, BW 214, BW 161, BW 174, BW 190, BW 202, and BW 28 RH models across single drum, tandem, and pneumatic tyred roller configurations
- Protects Valve Train Integrity — a fatigued or broken valve spring causes erratic valve timing, power loss, and accelerated wear on valve seats and guides; replacing with a correctly rated spring restores clean, stable operation
- Fuel System and Emission Compliance — correct valve spring tension is critical to maintaining proper combustion sealing, supporting the engine's designed fuel efficiency and emissions performance in your roller
A valve spring holds the engine's intake or exhaust valve closed against the cylinder head seat after each combustion cycle, working in constant opposition to the camshaft lobe. Maintaining the correct spring rate keeps valve timing precise and prevents blow-by between the combustion chamber and the rest of the engine. When a valve spring weakens through fatigue or breaks entirely, valves may float at operating speed, leading to misfires, reduced compression, and potential contact between valves and pistons — damage that can sideline a roller completely.
