As engine speed increases, the centrifugal clutch engages the inside of the drum. The integrated sprocket then drives the chain around the guide bar. Worn or damaged sprocket teeth create uneven chain movement and accelerate wear on the chain’s drive links.

Replace the drum when the sprocket develops deep grooves, chipped teeth, distortion or excessive movement. Before installation, clean the clutch area and inspect the clutch, washers, bearing and crankshaft surface. Replace damaged related parts before reassembly.

After fitting the new drum, confirm that it rotates freely and aligns correctly with the guide bar. Then install the matching .325-inch chain and test the chain brake and lubrication system before using the chainsaw.
