Hi Eisenmann. I have seen the folowing: Remove the spark plug and place a short length of rope (Nylon cord or shoe string) into the cylinder. This will hold the piston in place and keep the clutch from turning as you use a T20 or T25 Torx drive (depending oon model mine is a Ryobi 720r and used a T20)to loosen the screw and remove the drum, exposing the clutch. Remove one of the springs and the clutch assembly comes off. Note on my Ryobi I had to push the cord into the exhaust port instead of removing the spark plug. Hope this helps.
