Art look at the other side where the race slides in and see if it's all scored , it's possible that the race spun on the other side and it was loctited in place ?

Also now that you have the adjuster loose on the plate spin it back in so you can get the plate assembly further back towards the axle flange. once you do that heat the bearing race wit ha torch and let it cool , if it has any type of loctite on it that will break the bond.
