Sourced directly through authorized Multiquip supply channels, part number 71429522510 is the correct standard-bore specification for engines that have not been rebored or oversized.

Key Features
- Genuine OEM Ring Tolerancing — Manufactured to exact bore clearance and tension specifications for the Yanmar L48N6 engine, ensuring correct compression seal and oil control from the first start.
- Standard Bore Specification — Sized for the original, unmodified cylinder bore — the correct choice when replacing rings without cylinder reboring or oversize machining.
- Confirmed Fitment for L48N6-Powered Equipment — Verified for use on MTX85D rammers and other Multiquip equipment equipped with the Yanmar L48N6 engine.
- Restores Full Compression — Worn or broken piston rings cause loss of compression, increased oil consumption, and hard starting; a fresh OEM ring set restores engine power and smooth operation.
- Complete Set — Supplied as a full ring set for one piston, covering compression and oil control rings so you have everything needed for a proper engine rebuild or top-end service.
Piston rings form the dynamic seal between the piston and the cylinder wall, serving two critical functions: maintaining compression in the combustion chamber so the engine generates full power, and controlling oil by preventing it from entering the combustion area. Over time, rings wear, lose tension, or can break — leading to symptoms like low power output, excessive oil burning, blue smoke from the exhaust, and difficulty starting. Replacing the piston ring set with a correctly sized genuine OEM set restores the engine's compression integrity and oil control, extending the service life of the engine and returning the machine to full working performance.
