When you get ready to install the bearing, heat the motor faceplate to 250-300 degrees for an hour. You could try it cooler and work up, but that temp shouldn't bother it. Before you heat the plate, put the bearing in a ziplock bag and freeze for 3 hours or so in a good freezer. Coat the bearing in some oil and see if the cold bearing goes in the hot housing. That's how I would try it.
