The Multiquip 11971722900 is a genuine OEM Piston Assembly O.S=0.25 3TNV76 AR16-2 designed for the AR16-2 ride-on asphalt roller. As a factory-authorized component, this oversize piston assembly is manufactured to the exact dimensional tolerances required for a properly bored or honed 3TNV76 engine, ensuring correct compression and combustion sealing after an engine rebuild. DHS Equipment stocks this part to support contractors who need a dependable, specification-correct replacement to get their roller back to full working condition.
Key Features
- Oversize Specification Match — Manufactured at the 0.25mm oversize dimension for use in 3TNV76 engines that have been bored or honed to that spec, delivering correct piston-to-wall clearance.
- Genuine OEM Component — Sourced directly from Multiquip, this piston assembly meets the same dimensional and metallurgical standards as the original engine build — critical for maintaining proper compression in a diesel engine.
- Direct Engine Fitment for AR16-2 — Engineered specifically for the AR16-2 ride-on asphalt roller powered by the Yanmar 3TNV76 engine, eliminating guesswork during a rebuild.
- Restores Engine Compression — A correctly sized oversize piston seals the combustion chamber properly, restoring power output and fuel efficiency that a worn or damaged piston compromises.
- Rebuild-Ready Assembly — Supplied as a complete piston assembly, giving you the core component needed to complete an engine overhaul with confidence in fit and function.
A piston assembly is the heart of the combustion cycle in a diesel engine. It travels up and down within the cylinder bore, compressing the air-fuel mixture and transferring the force of combustion to the crankshaft through the connecting rod. An oversize piston — in this case 0.25mm — is used when the cylinder bore has been machined to remove wear, scoring, or taper, restoring the bore to a true, smooth surface. Installing the correct oversize piston ensures the proper clearance between the piston and the cylinder wall is maintained. If this clearance is too large due to a worn or incorrectly sized piston, the engine will suffer from blow-by, loss of compression, increased oil consumption, and reduced power — problems that will keep a roller off the job.
