The Bomag 05740742 Valve Spring is a genuine OEM component designed for Bomag BW 131 ACW-2, BW 131 AD-2, BW 131 ACW-3, and BW 131 AD-3 tandem rollers, as well as BMP 8500 and BMP 8500 Kubota trench compactors. Sourced directly from Bomag, this valve spring delivers an exact OEM match for consistent engine valve operation across all covered machines. Ordering by part number 05740742 ensures you receive the correct spring specification without guesswork or returns.
Key Features
- Genuine OEM Spring Tension — manufactured to Bomag's precise load and deflection specification, maintaining correct valve seating force for dependable engine performance
- Direct Drop-In Replacement — engineered to the same dimensions and wire profile as the original, seating correctly in the valve retainer without modification
- Broad Verified Fitment — compatible with BW 131 ACW-2, BW 131 AD-2, BW 131 ACW-3, and BW 131 AD-3 tandem rollers, plus BMP 8500 and BMP 8500 Kubota trench compactors
- Sustained Valve Timing Integrity — a correctly tensioned valve spring holds valves firmly closed on the compression stroke, protecting combustion efficiency and preventing premature seat wear
- OEM Part Number Confidence — referencing part number 05740742 when ordering confirms you are sourcing the exact Bomag-specified component, not an approximation
A valve spring holds each engine intake or exhaust valve firmly against its seat when closed and returns it quickly after the camshaft lobe releases it. Without adequate spring tension, valves can float at operating speed, causing misfires, lost compression, and accelerated wear to valve seats and guides. A worn or broken valve spring disrupts the engine's timing cycle, which on machines like BW 131 series tandem rollers and BMP 8500 trench compactors can result in rough running, reduced power output, and potential internal engine damage if left unaddressed.
