Removed the spark plug, then inserted a length of rope into the cylinder with a few inches remaining outside of the cylinder. This is to stop the engine from rotating when removing the drum and clutch. Then remove the clutch cover. Insert a torx driver into the clutch drum and remove it. The use a screwdriver and hammer to hit the edge of the clutch to loosen it from the shaft. Remove the clutch and install the new one. Then install the new clutch drum and clutch cover. Then remove the rope from the cylinder and replace the spark plug

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!).

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.

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 i s 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 !
