The Multiquip 13013ZJ1841 is a genuine OEM Piston Ring Set (0.75) designed for GA9.7HE gasoline-powered generators and AR13H, AR13HA/HAR, and AR13HC asphalt ride-on rollers. As a direct OEM replacement, 13013ZJ1841 is manufactured to the same specifications as the original component, ensuring a correct fit within the engine assembly. This is the 0.75mm oversize ring set, intended for engines that have been bored or measured to that oversize tolerance — confirm your engine bore spec before ordering. DHS Equipment stocks this part to help keep your Multiquip equipment running at full operating capacity.
Key Features
- Genuine OEM Compression and Oil Control: — Manufactured to the same ring tension and gap tolerances as the original, ensuring proper cylinder sealing and oil film control for this engine application.
- 0.75mm Oversize Specification: — This ring set is sized for a 0.75mm overbore — designed to install correctly in engines that have been machined to that specific oversize dimension.
- Broad Multiquip Fitment: — Compatible with GA9.7HE gasoline-powered generators and AR13H series asphalt ride-on rollers, including AR13HA/HAR and AR13HC variants.
- Restored Engine Compression: — Worn or broken piston rings cause compression loss, excessive oil consumption, and power drop. A correctly fitted ring set restores cylinder pressure and engine output to operating spec.
- Fuel System Integrity: — Proper ring sealing prevents combustion blowby from contaminating the crankcase oil, extending lubricant life and reducing wear on downstream engine components.
Piston rings seal the gap between the piston and the cylinder wall, performing two critical jobs: maintaining compression pressure in the combustion chamber and controlling the oil film on the cylinder bore. When rings wear, lose tension, or break, combustion gases escape past the piston — a condition known as blowby — causing a drop in power output, increased oil consumption, and contaminated crankcase oil. The 0.75mm oversize designation means this set is machined slightly larger than the standard ring to fit a cylinder bore that has been rebored to that oversize specification. Installing the correct oversize ring set restores a proper piston-to-wall seal, bringing engine compression and efficiency back to operating levels.
