Stihl 020 AV Clutch Removal

[Toneman]

How do you remove the clutch on this saw? Is a special tool required?
It appears that it is threaded on, but I'm not sure.

It is threaded, with reverse threads. I use an impact wrench to take them off.

I don't see any hex on the end of it to put a socket on. There is a nut that I can remove to take a cover off in order to see the actual clutch (springs and shoes,)
