Honda 31105-z0y-010 Flywheel Assembly

Product Description

The HONDA 31105-z0y-010 is a Phelon-type flywheel assembly designed for Honda small engines used in lawn and garden equipment. The flywheel is a core rotating component of the engine's ignition and charging system. It works with the magneto or stator to generate electrical current for ignition timing and, where equipped, battery charging. Installation and replacement of this part is typically performed by small engine technicians or experienced power equipment service professionals.

This flywheel assembly is intended for use in Honda-powered lawn and garden equipment. Phelon-style flywheels are common in small gasoline engines found in walk-behind mowers, tillers, and similar outdoor power equipment. It fits within the engine's crankshaft and ignition system and must be matched precisely to the correct engine family for proper ignition timing and mechanical fit.
