Hi joey357,

I will assume you are referring to the upper shaft as you mentioned the clutch drum. The upper shaft is sold as an assembly with the outer shaft tube. You will remove the shaft and tube by loosening the clamp screw on the front of the clutch cover assembly. You can then slide the tube and shaft out of the clutch cover assembly. You will need to remove all of the components which are mounted to the shaft tube assembly; the throttle, handle and accessory clamp. The new shaft tube assembly can now be installed and all of the other components replaced. The shaft has a square end milled on it that will slide into the square pocket on the clutch drum. You may need to rotate the opposite end of the shaft to get the shaft and drum to line up properly.

I hope this helps you with your trimmer repair!
