The Multiquip 11429903640 Decomp Spring is a genuine OEM component designed for MVH150, MVH200, MVH306, MVH406, MVC98, MRH800, and related plate compactor and roller models. As a direct OEM replacement, this spring is manufactured to the same specification as the original part, ensuring correct tension and reliable decompression function across every compatible machine. Confirmed fitment includes MVH-150D2, MVH150VD2, MVH206D, MVH-406DSY, MVH-200DA2, MVH-306DS2, MVC98D2, and MRH800DS2.
Key Features
- Correct Spring Tension: — Engineered to OEM tension spec, ensuring the decompression mechanism actuates at precisely the right point in the engine cycle for consistent easy starting.
- Genuine OEM Part: — Sourced directly from Multiquip, this part carries the same material grade and dimensional tolerances as the original factory component — not an approximation.
- Broad Fitment Across MVH and MVC Families: — Confirmed for MVH-150D2, MVH150VD2, MVH206D, MVH-406DSY, MVH-200DA2, MVH-306DS2, MVC98D2, and MRH800DS2 equipment.
- Restores Cold-Start Performance: — A worn or broken decomp spring causes hard starting or failure to start entirely; replacing it restores normal cranking compression relief and gets the engine turning over smoothly again.
- Direct Drop-In Installation: — Matches the original mounting points and hook geometry, allowing straightforward installation without modification to the engine assembly.
The decompression spring works as part of the engine's decompression system, which temporarily relieves cylinder pressure during the pull-start or electric-start cranking sequence. By reducing compression at the moment of startup, it allows the engine to build enough cranking speed before full compression kicks in — making cold starts significantly easier, especially on larger-displacement engines. When this spring fatigues, stretches, or breaks, the decompression valve can no longer function correctly, resulting in a stiff pull cord, difficulty starting, or a complete no-start condition.
