My bike was assembled poorly and I'm R&R'ing my headset.
The lower bearing isn't inserted fully into the frame bearing cup. As a result the fork isn't sitting as deeply into the frame as it should.
I have fried to sink the the bearing deeper but it's stuck. Trying to remove it has resutled in the bearing coming apart, leaving the outer race in the frame. I can see that it isn't seated as deeply as it should be...probably 3/16ths short of seated. But I can't budge it. There is no lip on the inside for me to get a punch or any other kind of tool on it.
Any ideas? Not sure I want to drive the cup out of the frame although I do have a new one to push back in if I need to.
I already know I need new bearings as the old one fell apart during my efforts. I was wondering about grinding some of the cup lip away so I could get to the back of the race.
