Kenmore washer # 110.92380200. Top agitator not moving (bottom one working just fine), so I went ahead and replaced those dogs as I'd heard I had to do.
Problem not fixed. I'm thinking of purchasing the agitator repair kit but not sure that will take care of issue since nothing visible seems to be broken
or worn out, and the dogs are now brand new. The problem is that while the bottom agitator moves just fine, the top agitator (only the top part that has those
fins) won't. It only moves freely, separately from the bottom, when I move it with my hand. On the other hand, the cam that goes inside the top agitator
moves just fine. How can the top agitator problem be fixed? Shall I get an agitator repair kit? Or do I need a whole new agitator? Or maybe something else?
I have no idea. Please, also include the number of the part I need to replace. Thanks a million!
Edited To Add: I'm looking at a picture of all the agitator parts from Sears parts direct and I don't see that my machine has the bearing. It has the agitator assembly (that works fine), the thrust spacer (not worn out or broken), the agitator auger (not worn out or broken), the agitator dogs (brand new), the cam (not worn out or broken), and then the washer and the screw (all fine), but I definitely don't see a bearing anywhere. Hmm... Maybe that's the problem? But how did the top agitator moved before if it never had a bearing?
