Hi, thanks for using JustAnswer.com. There are 2 little plastic tabs that hold number 9 in the picture to the lower part of the agitator. If you stand on the agitator and pull sharply on the upper clothes mover part, it will pull off. Refer to picture for breakdown.
I need to get #9 out of #3 which is attached to the base. I think the mechanism of #22 prevented me from doing so. I try to stand on the agitator and pull #3 out but it wouldn't let me. My goal is to replace #10 but I'm having the hardest time trying to get it out.
Here is the instruction sheet for disassembling per that exact agitator breakdown...
