The Multiquip 11465011121 Valve Spring is a genuine OEM component designed for MDR-9DYE power trowels, MVH-402DSB and MVH-304DSB reversible plate compactors, and the MRH-800DS walk-behind roller. Sourced directly from Multiquip, this valve spring meets the exact tension and dimensional specifications required for proper valve operation across these machine families. Whether you are servicing a trowel, a heavy-duty reversible plate, or a drum roller, the part is the correct OEM-spec replacement to restore your engine to proper working condition.
Key Features
- OEM-Spec Spring Tension — Manufactured to the exact coil tension and free-length specification the engine valve train requires, ensuring correct valve timing and seating pressure.
- Direct Drop-In Replacement — Engineered to install in place of the original spring with no reworking of the valve retainer or keeper assembly.
- Broad Cross-Family Fitment — Confirmed for MDR-9DYE, MVH-402DSB, MVH-304DSB, and MRH-800DS, covering power trowels, reversible plate compactors, and walk-behind rollers in one part number.
- Sustained Valve Seal Integrity — A correctly tensioned valve spring holds the valve firmly against its seat between combustion events, supporting consistent compression and fuel efficiency over time.
- Genuine Multiquip OEM Part — Supplied as an authentic Multiquip component, backed by the same quality controls applied to original production parts.
A valve spring holds each engine valve closed against its seat during the appropriate phase of the combustion cycle, then yields to the camshaft lobe to allow the valve to open at precisely the right moment. When a valve spring loses tension, cracks, or breaks, the valve can float, seat poorly, or fail to close fully — leading to compression loss, rough running, hard starting, and potential valve or piston damage. Replacing a worn or broken spring with the correct OEM-specification part restores proper valve timing and protects the engine from further wear across all compatible machine families.
