The Multiquip 71431022620 Piston with Rings (OS = 0.25) is a genuine OEM component designed for the MVH406DSY reversible plate compactor and MRH800DS2 walk-behind roller. As a direct factory replacement, this oversized piston — ground to a 0.25 mm oversize specification — is sourced directly from Multiquip to ensure a correct fit in engines that have been bored to that oversize tolerance. DHS Equipment stocks genuine Multiquip parts so you can get your machine back to full working condition with confidence.
Key Features
- Genuine OEM Piston Construction — Manufactured to Multiquip's exact dimensional tolerances for correct compression sealing and bore clearance in the engine.
- 0.25 mm Oversize Specification — Engineered for engines that have been professionally bored 0.25 mm over standard, ensuring correct piston-to-wall clearance after a cylinder regrind.
- Includes Piston Ring Set — Supplied complete with rings, so compression, oil control, and sealing components are replaced together as a matched assembly.
- Confirmed Fitment for MVH406DSY and MRH800DS2 — Verified genuine OEM replacement for the MVH406DSY reversible plate compactor and MRH800DS2 walk-behind roller engine.
- Restores Full Engine Compression — A worn or improperly sized piston causes loss of power, excessive oil consumption, and hard starting; this OEM piston restores proper cylinder pressure and engine output.
The piston is the reciprocating component inside the engine cylinder that transfers combustion energy to the crankshaft through the connecting rod. It works in conjunction with the piston rings to seal combustion gases above and control oil film below, maintaining the compression needed for reliable engine starting and consistent power output. When a piston or its rings are worn, scored, or incorrectly sized, the engine loses compression, burns oil, and delivers reduced performance — making correct piston selection, including the right oversize dimension, critical to a successful engine rebuild.
