Husqvarna 576423301 Flywheel Assembly

Product Description

The HUSQVARNA 576423301 is a flywheel assembly designed for use in small-engine outdoor power equipment. The flywheel is a rotating mass mounted on the crankshaft that stores rotational energy, maintains engine timing, and works in conjunction with the ignition system to generate the magnetic pulse needed to fire the spark plug. It is a core engine component and its correct installation is essential for reliable engine operation. This assembly is typically serviced by small-engine technicians or qualified outdoor power equipment mechanics.

This flywheel assembly is suited for HUSQVARNA-branded lawn and garden equipment powered by small single-cylinder engines. Typical applications include walk-behind mowers, handheld power equipment, and related outdoor power products where the OEM flywheel has failed, been damaged, or requires replacement as part of a broader engine service. Refer to the equipment model's parts diagram to confirm fitment before installation.

Compatibility

Designed as an OEM-style replacement flywheel assembly for HUSQVARNA lawn and garden power equipment. Confirm compatibility using the equipment model number and official HUSQVARNA parts diagrams prior to ordering.

Installation Notes

Flywheel replacement should be performed by a qualified small-engine technician. Disconnect the spark plug wire and allow the engine to cool completely before beginning any service. A flywheel puller tool is typically required for safe removal of the original flywheel without damaging the crankshaft taper. After installation, verify ignition coil air gap clearance per the equipment service manual before returning the unit to operation.
