Jeff,

I have been consistently incorrect on your COE so far. This might be bogus info too as I don't know what that upper race looks like or how it's captured. Bearing separators can squeeze a race off of a tight fit when there isn't room to tap or bang them.

Maybe one of these would get the operation off to a good start.
