Description
Overview:
The Clutch Spring for Husqvarna chainsaws is a small but critical component made from durable hardened spring steel. It maintains the correct tension on the clutch shoes so the clutch engages smoothly at the right engine speed and releases at idle. This Genuine Husqvarna part is engineered for reliable performance on petrol chainsaws such as the 545 and 550XP. As a direct replacement for OEM No. 597 64 54-01, it is built to match the original specification and fit precisely within the clutch assembly. Replacing a tired or stretched spring helps prevent the chain from moving at idle and restores smooth take-up under load, supporting safe and efficient cutting in professional and DIY use.
