Description
Overview:
The Clutch Assembly for Husqvarna chainsaws is a centrifugal drive component that engages the chain at working speed and disengages it at idle to protect the bar and chain. Built with robust steel clutch shoes and a high-tension spring, it is designed for reliable torque transfer and consistent pick-up under load. This is a Genuine Husqvarna part identified by OEM No. 537 11 05-03 (MPN 537110503), offering a direct replacement for worn or slipping clutches. It is suitable for a wide range of mid-size Husqvarna saws used by tradespeople, arborists, landscapers, and home users. Ideal examples include the Husqvarna 450 and 455, where correct clutch function is critical for starting, idling, and smooth cutting performance.
