Description
Overview:
This genuine Husqvarna flywheel is a core engine component for petrol disc cutters, designed to maintain crankshaft momentum and support stable ignition. Cast from durable aluminium alloy with cooling fins and embedded magnet segments, it helps regulate engine speed, smooths acceleration, and drives cooling airflow through the shroud. Built for demanding cutting environments, it fits Husqvarna professional machines such as the K760 and K770. As a direct OEM replacement, it works with the original keyway and hardware to restore correct balance and performance. Use it during routine servicing or full rebuilds to keep starting, idling and cutting performance consistent, while protecting the engine from overheating and vibration-related wear.
