The Multiquip 71429522540 is a genuine OEM Piston Ring Set OS=0.25 designed for Multiquip rammers and plate compactors including the MT-76D2, MT-86D2, MVC98D2, MVH-150D2, and MVH150VD2. As a direct OEM replacement, this oversize ring set is engineered to the exact tolerances required for a proper cylinder bore fit following a 0.25mm oversize rebore. Sourced directly from Multiquip, part number 71429522540 ensures accurate fitment and consistent engine performance across all compatible models. Keep this part on hand as part of a planned engine rebuild to get your equipment back to full operating condition quickly.
Key Features
- Oversize Bore Compatibility — Manufactured to OS=0.25 specification, matching a 0.25mm overbore for correct ring-to-wall clearance and a proper seal.
- Genuine OEM Construction — Built to the same material grade and ring tension specifications as the original rings, maintaining combustion efficiency and oil control in high-vibration engine applications.
- Broad Fitment Across Two Equipment Families — Compatible with MT-76D2 and MT-86D2 rammers as well as MVC98D2, MVH-150D2, and MVH150VD2 plate compactors.
- Restores Full Compression — Worn or broken piston rings allow combustion gases to bypass the piston, causing hard starts, power loss, and excessive oil consumption; a fresh ring set restores cylinder pressure and engine output.
- Engine Rebuild Essentials — Designed to install as part of a complete engine overhaul; pairs with a cylinder rebore for a matched, long-lasting rebuild result.
Piston rings seal the gap between the piston and the cylinder wall, serving three critical functions: containing combustion pressure to drive the piston, transferring heat away from the piston into the cylinder wall, and controlling the oil film on the cylinder bore. When rings wear, lose tension, or break, compression drops, oil burns into the combustion chamber, and the engine loses the power needed to drive the compaction mechanism. An oversize ring set like the part is used after a cylinder has been bored out to restore that tight seal — skipping this step or using an incorrect ring size will result in poor compression and a short engine life regardless of the quality of the rebore work.
