Description
Overview:
This genuine Husqvarna centrifugal clutch is a direct replacement part for selected high‐output cut-off saws and chainsaws, including the 3120K and 394XP. It is engineered to transmit engine power to the drive system only when required, helping the machine idle safely and engage the blade or chain smoothly under load. Built from durable, heat‐resistant steel with robust friction components and springs, it withstands high temperatures and repeated starts typical of heavy cutting work. The precise fit and balance support consistent performance and reduce vibration. Supplied to OEM specification under Husqvarna part number 503 14 49 03, it restores reliable drive engagement on compatible machines and helps protect engine and drive components from premature wear by allowing controlled slip during start‐up and heavy cuts.
