Product review (5 stars): Good kit. Easy repair that takes 10 minutes.
10 minutes to replace the cam, dogs, and o-ring.  You'll need a socket wrench with a looooong extension. I had to use two extensions together to reach the nut. Undo the nut, pull out the whole agitator.  the rest just pulls apart. The little black rubber washer....I'm not sure what that's for because there was no place for it in my washer.  Must be for other models.
One minor thing...the instructions say to apply thrust washer grease to the new thrust washer. They don't include any of that in the kit. Who has thrust washer grease laying around their house? They should include a little tube of it.  I just skipped it.
Now my machine works perfectly
