This is an authentic OEM sourced part which is specially made for Craftsman chainsaws. 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. It is a high-quality clutch drum which is made of durable metal and is sold individually. Please note, the <a href="http://www.ereplacementparts.com/clutch-p-1099174.html" target=blank><u>#530057907 Clutch </u></a> is sold separately.
Remove the clutch cover by removing two nuts. Remove e-ring and washer in front of the clutch drum. Remove old drum, do not lose the inside washer. Place new clutch drum on over the clutch. Install outside washer and e-ring, then attach the clutch cover. Done.

4. Replaced the clutch drum. Placed a new clutch washer back on (old one was perfectly serviceable but decided if I was in there I would replace it). Put the new e-clip on - be careful here, it can go flying!
