This is an OEM sourced replacement part used on Echo chainsaws. The clutch drum works in unison with the clutch. Together, they make it possible for the engine to idle without rotating the trimmer head. When the throttle is applied, the clutch assembly expands into the clutch drum, which activates the trimmer head.A common issue with the clutch drum is an erosion of the spindle where the upper drive shaft connects to the assembly. The square corners of the spindle (which accommodate the square drive shaft) become rounded, and the shaft disengages. This high-quality drum-clutch is made of durable metal and is sold individually. A screwdriver and a wrench will be needed to perform this repair. Refer to the appropriate diagrams for your specific model to ensure the proper replacement procedure.

Saved my saw
My chainsaw stopped cutting. Even with a new bar and chain. I thought I was going to have to buy a new saw.
I found this site and was able to upload a parts diagram and easily found the part to fix my saw. The part arrived very quickly and was a perfect replacement. Now my saw operates like new.
Excellent service! Exceptional quality!
