The Multiquip 71431022540 is a genuine OEM Piston Ring Set (O.S=0.25) designed for the MVH406DSY reversible plate compactor. As a direct Multiquip OEM replacement, this oversize ring set is engineered to the exact tolerances required for engine rebuild applications on the MVH406DSY, ensuring proper bore-to-ring fit after cylinder honing. Sourced directly through authorized Multiquip supply channels, 71431022540 delivers the fitment accuracy that engine rebuilds demand — no guesswork on sizing or compatibility.
Key Features
- Oversize Bore Compatibility — Sized at 0.25mm oversize (O.S=0.25) to match a freshly honed or bored cylinder, restoring correct compression ring sealing geometry.
- Genuine OEM Construction — Manufactured to Multiquip OEM specifications, with ring tension, material grade, and profile matched to the original engine design for proper combustion sealing.
- Direct Engine Rebuild Fit — Drops into the engine assembly as part of a standard oversize rebuild, using the same installation procedure as the original ring set.
- MVH406DSY Fitment Confirmed — Verified for the MVH406DSY heavy-duty reversible plate compactor, eliminating compatibility risk during engine reconditioning.
- Compression and Oil Control Restored — A correctly fitted piston ring set seals combustion gases, controls oil consumption, and transfers heat from the piston — all critical to sustained engine output on a high-demand compaction machine.
Piston rings form the dynamic seal between the piston and the cylinder wall, serving three essential functions: containing combustion pressure to drive the power stroke, scraping excess oil from the cylinder bore to prevent burning, and transferring heat away from the piston into the cooled cylinder wall. Over time, rings wear and lose tension, leading to compression loss, increased oil consumption, and reduced engine power — symptoms that directly affect compaction output. An oversize ring set like the part is used when the cylinder bore has been machined to a larger diameter during reconditioning, restoring the tight seal needed for full engine performance.
