They aren’t stuck, it’s just that the swingarm acts as the bearing housing, so the outer race is not visible on one side. So you have to drive/force the bearing out on the inner race, which has the chances of going horribly wrong.
Was going to heat the frame a bit to make it slightly easier to get them out, whichever way I do it.
Intrigued as to how to pull with bolt/nut – would need some kind of interesting brace that allowed the bearing to come towards it….
Heath Robinson time I think.
