The Multiquip 11431011120 Valve Spring is a genuine OEM component designed for MVH406DSY and MRH800DS2 series equipment. Sourced directly from Multiquip, this OEM part is manufactured to the exact specifications required by your machine, ensuring proper valve operation and consistent engine performance. Confirmed fitment covers the MVH406DSY reversible plate compactor and the MRH800DS2 walk-behind roller, making it the correct choice for operators maintaining either of these machines.
Key Features
- Genuine OEM Spring Tension: — Manufactured to the exact load and free-length spec of the original, so valve timing and seating pressure remain consistent with engine design.
- Direct Drop-In Replacement: — Engineered to seat in the same valve retainer groove as the factory spring, requiring no modification to the cylinder head or retainer hardware.
- Confirmed Fitment: — Verified for the MVH406DSY reversible plate compactor and MRH800DS2 walk-behind roller.
- Engine Breathing Performance: — A correctly tensioned valve spring holds the valve firmly closed during combustion and opens it fully on each stroke, maintaining compression and fuel efficiency in demanding compaction and rolling applications.
- Fuel System Safety: — Proper valve spring tension prevents valve float at operating RPMs, which can cause uncontrolled combustion events and accelerated wear on valve seats and guides.
A valve spring holds each engine valve closed against its seat between actuation cycles, maintaining the compression seal needed for efficient combustion. When a valve spring weakens or breaks, the valve may not close fully or may float at higher RPMs, leading to power loss, misfires, and rapid damage to valve seats and guides. Replacing a worn spring with the correct OEM part restores proper valve movement and protects the engine from compounding internal damage.
