The Multiquip 31110ZJ1840 Flywheel AR13H GX610K1QZB2 is a genuine OEM component designed for AR13HA/HAR, AR13H, and AR13HC asphalt ride-on rollers. As a direct Multiquip OEM part, the 31110ZJ1840 is manufactured to the same specification as the original, ensuring a correct fit with the Honda GX610K1QZB2 engine used across the AR13H series. Sourced through DHS Equipment, this part is the right choice when accuracy and reliability matter on a working roller. Verify your model code against the fitment list before ordering to confirm compatibility.
Key Features
- Genuine OEM Rotating Mass Integrity — Manufactured to original Multiquip specification, delivering the correct rotational inertia and balance required for smooth engine operation on the GX610K1QZB2-powered AR13H series.
- Engine-Matched Installation — Engineered to mate directly with the Honda GX610K1QZB2 crankshaft taper and keyway, meaning the flywheel seats and torques correctly without modification to the engine's ignition timing reference.
- Confirmed Fitment for AR13H Series — Compatible with AR13HA/HAR, AR13H, and AR13HC asphalt ride-on rollers; always cross-reference your machine's model code to confirm before installation.
- Ignition Timing Accuracy — The flywheel carries the reluctor or magneto trigger points that govern spark timing; a worn, cracked, or out-of-balance flywheel causes misfires, hard starts, and erratic engine speed under compaction load.
- Electrical System Integrity — On Honda GX610 engines the flywheel also houses the charging magnets for the alternator stator; a correctly seated OEM flywheel maintains proper charging output to keep the roller's electrical systems running.
The flywheel is a heavy rotating disc bolted directly to the engine crankshaft. Its primary job is to store rotational energy between power strokes, smoothing out the pulses of combustion into steady, consistent output — critical on a ride-on roller where uneven engine torque translates directly into inconsistent drum pressure and surface finish. On the Honda GX610K1QZB2 engine fitted to the AR13H series, the flywheel also carries the magnets that generate charging current for the onboard electrical system and provides the trigger reference point for ignition timing. A flywheel that is cracked, has a damaged keyway, or has lost a magnet will cause symptoms ranging from hard starting and rough running to a complete failure to fire or a dead charging circuit, taking the roller out of service until the component is replaced.
