627 vertical Armature play

Train NutOGR Forum Member

I have a 627 that has excessive vertical Armature play. Looked at the service manual but it doesn't really address the 627 motor itself. One diagram of a similar motor looks like it has a ball bearing on the bottom of the Armature shaft in the bearing hole. My question is is that correct? And if it is, how can you tell if the ball bearing is not already in there. It's hard to see down in that tiny hole. Very hard to see in there with the grease and size of it.
