All gears have damage, and the other is completely broken. I can be happy that everything has remained stuck.
Everything ordered new. I want to take the bearings out and the first one went out easily. Then I started on the 2nd and hit a hole through the other side.
For when you wonder how I did that and how you should never do that. I use wet paper. With this I completely fill the bearing and insert exactly a piece of metal in it. With this you can easily remove the bearing. I did not realize that the back is very weak and I could break it like that.
Now I have special glue that I hope will stick to it. It was exactly 2 pieces broken in half.
