The Multiquip 11487222150 Piston Ring Set OS 0.50 is a genuine OEM component designed for the MVH-306DS2 heavy-duty reversible plate compactor. This oversized (OS 0.50) ring set is engineered for engines that have been bored to the 0.50 mm over-bore specification, restoring proper cylinder-to-piston clearance and compression. Sourced directly from Multiquip, 11487222150 delivers the exact fitment and material tolerances required for this machine. If your MVH-306DS2 has undergone an engine rebuild, this is the correct ring set to complete the job to OEM specification.
Key Features
- Correct Oversize Grade — Sized at OS 0.50, this ring set matches engines bored to the 0.50 mm oversize, ensuring proper seal against a freshly honed cylinder wall.
- Genuine OEM Construction — Manufactured to Multiquip's precise ring gap, radial depth, and tension specs for the MVH-306DS2 engine, so combustion seal and oil control perform as originally designed.
- Direct Rebuild Fitment — Drops into the correct ring grooves on the oversize piston without modification, pairing cleanly with the cylinder bore after an engine overhaul.
- Compression and Oil Control Restored — A worn ring set allows blow-by, loss of power, and excessive oil consumption; replacing with this part restores full compression and prevents oil from entering the combustion chamber.
- Confirmed for MVH-306DS2 — Verified fitment for the MVH-306DS2 reversible plate compactor, a heavy-duty unit used in demanding soil and asphalt compaction applications.
Piston rings form the critical seal between the piston and the cylinder wall inside the engine. They serve two purposes: holding combustion pressure in the power stroke to drive the piston down, and scraping excess oil off the cylinder wall to prevent it from burning. When piston rings wear, gap excessively, or break, the engine loses compression, burns oil, produces blue smoke, and delivers noticeably less power to the compactor's vibratory system. In a rebuilt or bored engine, standard-size rings will not seat correctly against the larger bore diameter — an oversize set like this OS 0.50 ring set is required to restore a proper seal and return the engine to full working condition.
