The Multiquip 71431022550 Piston Ring Set (OS=0.50) is a genuine OEM oversize piston ring set designed for the MVH-406DSY reversible plate compactor. As a factory-authorized component, this ring set is manufactured to the exact tolerances required for a proper engine seal on MVH-406DSY equipment. Sourced directly from Multiquip, part 71431022550 is the correct specification for engines that have been bored to a 0.50mm oversize, making it the right choice for engines undergoing a precision rebuild.
Key Features
- OEM-Grade Sealing Tolerances — Manufactured to exact compression and oil-control ring dimensions required by the MVH-406DSY engine, ensuring proper cylinder sealing after a 0.50mm overbore.
- Correct Oversize Specification — Sized at OS=0.50 to match bored cylinders precisely, allowing drop-in installation without further machining when the bore is prepared to the matching oversize.
- Confirmed Fitment for MVH-406DSY — Verified genuine OEM replacement for the Multiquip MVH-406DSY heavy-duty reversible plate compactor.
- Restores Engine Compression — Properly seated oversize rings restore cylinder compression and oil control, returning the compactor's engine to full operating output after a rebuild.
- Supports a Complete Engine Overhaul — Using the correct OEM ring set during a rebuild prevents premature wear, oil consumption, and loss of compaction force that result from improperly sized or worn rings.
Piston rings seal the combustion chamber between the piston and the cylinder wall, controlling compression pressure and preventing engine oil from entering the combustion zone. When rings wear, an engine loses compression, burns oil, and produces significantly less power — on a plate compactor, this directly reduces compaction force and overall productivity. An oversize ring set like the 71431022550 (OS=0.50) is used during an engine rebuild after the cylinder has been bored out to remove wear damage, restoring the tight seal needed for efficient combustion. Using the correct oversize specification is critical: an incorrectly sized ring set will not seat properly and will cause the same symptoms it was meant to fix.
