The Multiquip 13101ZJ1840 is a genuine OEM Standard Piston GX610 HC- designed for AR13HA/HAR, AR13H, and AR13HC asphalt ride-on rollers as well as the GA9.7HE gasoline powered generator. As a direct Honda GX610 engine component, this piston is manufactured to OEM specification, ensuring correct bore diameter, ring groove geometry, and pin bore alignment for a proper fit inside the engine cylinder. Sourced directly through Multiquip's authorized parts supply chain, part number 13101ZJ1840 delivers the dimensional accuracy that an engine rebuild demands. Confirm your model code against the fitment list before ordering to ensure compatibility with your specific unit.
Key Features
- OEM Bore and Ring Groove Accuracy — Cast and machined to Honda GX610 specification, this standard-size piston maintains correct compression ratios and ring seal integrity critical to engine performance.
- Drop-In Engine Rebuild Component — Engineered to seat directly into the GX610 cylinder bore with correct pin bore alignment, supporting a straightforward engine overhaul without custom fitting.
- Broad Fitment Across Rollers and Generators — Compatible with AR13HA/HAR, AR13H, and AR13HC ride-on asphalt rollers and the GA9.7HE gasoline powered generator sharing the Honda GX610 engine platform.
- Compression and Power Restoration — A worn or scored piston causes loss of compression, increased oil consumption, and rough engine operation; replacing it with 13101ZJ1840 restores proper combustion and engine output.
- Fuel System Integrity — Correct piston-to-wall clearance prevents blow-by, protecting the crankcase and oil from fuel contamination that can accelerate wear across other internal engine components.
The piston is the reciprocating component inside the engine cylinder that transfers combustion energy to the crankshaft via the connecting rod. On Honda GX610-equipped machines like the AR13 roller series and GA9.7HE generator, the piston operates under high heat and pressure cycles during every hour of use. Over time, the piston skirt, ring lands, or pin bore can wear, causing compression loss, excessive oil burning, or engine knock. Replacing the piston with the correct standard-size OEM part is essential during any engine rebuild to restore full power output and protect downstream drivetrain or hydraulic components that depend on consistent engine performance.
