The Multiquip 13011ZJ1841 is a genuine OEM Piston Ring Set (OS 0.25) designed for the GA9.7HE gasoline-powered generator and AR13H series asphalt ride-on rollers, including the AR13HA/HAR and AR13HC. As a factory-sourced component, it is manufactured to the exact tolerances required for a proper seal between the piston and cylinder wall in these Honda-powered machines. This oversize 0.25mm ring set is intended for engines that have been bored or honed during a rebuild, restoring correct compression and oil control to the cylinder. Confirm your machine's model code and engine bore specification before ordering to ensure a correct match.
Key Features
- OEM Ring Geometry and Material Grade — Manufactured to the exact radial thickness, gap clearance, and ring-face profile specified for this engine, ensuring consistent cylinder sealing under load.
- Oversize 0.25mm Specification — Sized for cylinders that have been bored or honed 0.25mm over standard, making this the correct choice for engine rebuilds where standard rings would run loose.
- Verified Fitment Across Multiple Platforms — Compatible with GA9.7HE generators and AR13H, AR13HA/HAR, and AR13HC asphalt ride-on rollers equipped with the matching Honda engine.
- Compression Restoration — Worn or broken piston rings cause blow-by, loss of compression, excessive oil consumption, and hard starting; a correctly sized ring set restores engine power and efficiency.
- Rebuild-Ready Component — Supplied as a complete ring set so all rings on the piston are replaced together, preventing mismatched wear between old and new rings after a bore job.
Piston rings seal the combustion chamber between the piston and the cylinder wall, maintaining compression pressure while controlling the thin film of oil needed to lubricate the cylinder bore. They perform three jobs simultaneously: containing combustion gases above the piston, scraping excess oil back down the cylinder walls, and transferring heat from the piston into the cylinder. When rings wear, gap out, or break, combustion gases escape past the piston — a condition known as blow-by — resulting in lost power, increased oil burning, fouled spark plugs, and accelerated internal wear. Replacing them with a correctly specified oversize set during an engine rebuild is essential to returning the engine to full operating condition.
