I have an actuator taken apart on my workbench now, I don't recall a third gear. I just got a new actuator that I havent installed yet. If I move the arm (silver piece on left) it breaks free from the pivot. I can move it until it touches plastic in both directions. On the new one, it is rock solid.
I think the arm breaking free from the pivot is the most common problem. Tomorrow I will look again for that third gear and post back what I find.
