Multiquip 31100ZE2812 Flywheel Complete GX240K1 HC-5

The Multiquip 31100ZE2812 is a genuine OEM Flywheel Complete GX240K1 HC-5 designed for GA3.6HZ and GA3.6HA gasoline powered generators. As a direct OEM replacement sourced through Multiquip's authorized parts network, 31100ZE2812 is manufactured to the exact specification of the original component. Confirm your model code before ordering — this flywheel assembly is validated for the GA3.6HZ and GA3.6HA series.

Key Features

• Genuine OEM Construction — Manufactured to the exact mass and magnetic pole configuration required by the GX240K1 HC-5 engine, ensuring correct ignition timing and charging output from the moment it is installed.
• Direct-Fit Replacement — Engineered to mount directly to the GX240K1 HC-5 crankshaft taper and keyway, requiring no modification to the engine block or ignition system components.
• Confirmed Fitment — Validated for Multiquip GA3.6HZ and GA3.6HA gasoline powered generator models.
• Consistent Power Output — A properly functioning flywheel maintains rotational inertia across the engine cycle, keeping voltage output smooth and stable under varying generator loads.
• Ignition System Integrity — The flywheel houses the magneto magnets that trigger the ignition coil; a cracked, worn, or out-of-spec flywheel can cause misfires, hard starting, or complete ignition failure — replacing it with the correct OEM unit restores full system function.

The flywheel is a critical rotating mass bolted to the engine crankshaft that serves two primary functions in a gasoline powered generator: it smooths out the power strokes of the engine to maintain consistent RPM under load, and it carries the permanent magnets that drive the ignition system and, in many configurations, the charging circuit. When a flywheel cracks, loses a magnet, or becomes damaged at the taper or keyway, the result is erratic ignition timing, rough running, or a complete no-start condition. Replacing a failed flywheel with a genuine OEM unit like the Multiquip 31100ZE2812 restores both mechanical balance and ignition reliability to the engine.
