Parts Used:

1. Found the Clutch discs were obsolete. (Homelite bc900 and many other trimmers I found in my research.)
2. I discovered while researching that the clutch parts breakdown used the same clutch washer and the same drum, but it used a different clutch which wasn\'t obsolete. Purchased new clutch, drum, and the two different sized w ashers. Parts were for Ryobi BC30.
3. Removed the clutch drum by loosening captive torx screw in end of drum, sliding off the drum.
4. Removed the clutch each of the two clutch discs by tapping a screwdriver with a hammer to spin then off.
5. Removed old clutch washers.
6. Replaced washers and clutch in order for other model trimmer.
7. Tighten clutch with adjustable plier.
8. Installed new drum.
