I followed the instructions others had posted above and the repair could not have been easer. Saved my 4-cycle trimmer for less than $100 and that including buying a full set of torx screwdrivers (because why only buy the one you need!).

, T-20 star bit screwdriver !!
Parts Used
It's pretty easy to change the clutch drum , check out the U-tube video for some tips on how to do it . The only thing is you'll need Star ended screwdrivers ! For the most part you can use magnetic bit screwdrivers , ...BUT !! to remove and replace the clutch drum you'll need a T20 thin shafted driver , because the retaining screw is about 1 1/4 inches ( 30m ) down inside the well the drive shaft fits into and that's about 1/4 inch ( 6m ) hole . Now to get mine off I measured down marked it , and cut the collar off with a hacksaw , BUT again to remount the new your going to need that T20 driver !! The trimmer works like a champ now !! Good Luck !

I took off the boom, clutch housing, unscrew the bolt in the center of the clutch drum. Then, with a hammer and a drift released the clutch by hitting it counter-clockwise. I had to tap the hole in the boom so that I could screw bake the throttle control and shut off switch.
