1
Before you replace the clutch drum on your chainsaw first make sure the chainsaw’s engine has cooled.

4
Remove the nuts securing the clutch cover.
5
Pull the cover off.

Remove the chain bar and chain.
7
Confirm that the chain brake is in the “off” position.

Use a flathead screwdriver to remove the c-clip and pull off the old washer, clutch drum and bearing.

10
Slide the new bearing onto the drive shaft followed by the new clutch drum and washer.
11
Secure the assembly with the c-clip.

You will probably need to rotate the tension adjustment screw counter-clockwise to properly align the tensioner.
