Top of the agitator wasn't spinning.

I simply removed the bolt from the inside of the agitator and pull the whole the straight up. It came aloose pretty easily. I took the old clothes mover off and put the new one on. On the inside of the mover the dog ears and spacer easily comes out. I removed the spacer and replaced the dogs ears. I put everything back together the way it was when I took it apart. It works as good as it did when I first got it.
