It's a little unusual, and definitely not standard engineering to press fit both races in a ball bearing. One should be a very close slip fit, which of course makes applied force critical to be aligned.
I wouldn't use a 60 deg point on the drift bar. Tends to send the hammer force to the side rather than right down the middle. Round the corners of both ends. One to be sure you don't flare it into breaking off shards on the dumb end. Since you are either replacing or seriously cleaning the bearings anyway, have you thought about drilling and tapping a hole in those dust plugs? it would either help you remove them (and later screw a plug back in after installing them back) or push out the shaft.
