The Multiquip 71412022630 is a genuine OEM Piston With Ring OS=0.50 Yanmar L48N6 designed for L48N6-equipped Multiquip machinery. As a direct OEM replacement, this oversize piston and ring set is sourced to Multiquip's original specifications, ensuring proper fit and function in the L48N6 engine. The 0.50mm oversize designation makes this the correct choice for engines that have undergone cylinder bore reconditioning to that specific oversize. Verify your engine's bore size before ordering to confirm this is the right oversize specification for your application.
Key Features
- Genuine OEM Piston Construction — Manufactured to the original dimensional and metallurgical specs of the Yanmar L48N6 engine, ensuring correct compression height, ring groove geometry, and piston-to-wall clearance.
- 0.50mm Oversize Specification — Purpose-built for cylinders bored to the 0.50mm oversize standard, restoring proper compression and seal after an engine rebuild.
- Piston and Ring Set Included — Ships as a complete assembly with matching rings, simplifying the rebuild process and ensuring ring-to-groove compatibility right out of the box.
- Direct Fit for L48N6-Equipped Machines — Confirmed fitment for Multiquip equipment powered by the Yanmar L48N6 engine, eliminating guesswork during engine overhaul.
- Compression Integrity Restored — A correctly sized piston and ring set seals combustion gases effectively, restoring full power output and fuel efficiency to the engine after reconditioning.
The piston is the reciprocating component inside the engine cylinder that transfers combustion energy to the crankshaft, driving the machine's core functions. The piston rings seal the combustion chamber, preventing blow-by gases from entering the crankcase and oil from entering the combustion area. When a piston or its rings wear beyond tolerance — or when a cylinder is rebored — an oversize piston like this one is required to restore that critical seal, proper compression, and consistent engine output. Installing the correct oversize specification is essential; an incorrect fit will result in poor compression, oil consumption, and premature engine failure.
