Description
Overview:
This Genuine Husqvarna clutch drum is a direct-fit replacement for Husqvarna 266 and 66 petrol chainsaws. Manufactured from durable steel for long service life, the drum engages with the clutch shoes and drives the chain via the sprocket interface, helping to deliver smooth, efficient power transfer from the engine to the guide bar. Replacing a worn or scored drum restores cutting performance, reduces chain slip, and supports safe operation. Precisely machined to OEM tolerances for correct alignment, it integrates seamlessly with existing clutch components on your saw. Genuine status means assured compatibility and reliability in demanding use. Manufacturer Part Number: 503 65 09 01 (also referenced as 503650901).
