Hello, I've got a 68 SA 200 with a worn out bearing pocket in the exciter housing. What is the original ID?

Mine is 0.0005" larger than the 6208 bearing OD and the bearing slides in and out by hand and showed signs of spinning in the housing. I am thinking this may have been what ruined the thrust surface on the crank of the F163 in it.

What type of fit should it be and how many tenths or thousandths smaller than the OD of the armature bearing should it be? I keep seeing guys having to use pullers or bottle jacks to get their exciter cage off and mine slide right off when I unbolted it.
