Description
Overview:
This Genuine Husqvarna clutch spring is a durable steel component for the centrifugal clutch used on Husqvarna brushcutters and clearing saws, including the 345FR and 545FR. It maintains correct clutch engagement and disengagement, helping the drive to take up smoothly at working speed while preventing head or blade movement at idle. Replacing a worn or broken spring restores consistent performance, reduces unnecessary wear on the clutch shoes and drum, and keeps the machine safe and predictable to use. Built for repeated cycling and vibration, it is a direct-fit replacement identified by OEM number 505 43 53-02, ensuring correct fitment on the specified models.
