Description
Overview:
This clutch spring is a Genuine Husqvarna part for the 555 chainsaw and selected clearing saws. Made from high‐tensile spring steel, it maintains the correct tension on the centrifugal clutch shoes, helping the clutch engage smoothly at the right engine speed and release cleanly at idle. Built to cope with heat, vibration, and repeated cycles, it restores reliable drive take‐up and prevents chain creep or clutch slip. Designed for a direct fit in the clutch assembly, it is suitable for routine service or replacing a fatigued spring. OEM No. 578 76 94-01 ensures the right specification and fit for Husqvarna 555 and 555FXT platforms used in forestry, landscaping, and grounds maintenance.
