This is an OEM sourced replacement part used on gas trimmers. A centrifugal clutch is a part that uses centrifugal force to connect two concentric shafts, with the driving shaft nested inside the driven shaft. Today’s centrifugal clutches will function even when they shouldn’t, far beyond the point of when they need to be replaced. Keeping an eye on equipment performance will determine when the centrifugal clutch requires attention. Please note the clutch drum, spacer and washer are all sold separately. This clutch is made out of metal and it is sold individually.
To replace this item you would need a screwdriver and pliers.

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 washers. 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.

Tools Used

Used parts diagram from this site.
Main trick was a clutch removal from the shaft.
I didn't realize that a clutch is threaded to the shaft and broke it during removal.
New clutch from this site actually shows an arrow that indicates a direction of rotation for a clutch to be removed. Original clutch didn't have that.
