Jeff,
I reached out to one of my mentors, a master machinist and mechanical engineer who is very skilled in machine tool repair. He suggested heating the cutter-head up to about 150 degrees for a day and applying a penetrant like Kroil to the bearing/spindle interface. Then let it cool overnight and press the spindle out of the bearing. He doesn't think you will damage the bearing by doing this.
I know that I've seen the Timken bearing load tables somewhere, but I can't seem to find them now. You might try the NSK or SKF tech data for bearings of that size, if you can't find Timken's data. If you find the tables, please let me know where.
If you have a large enough arbor press, that would probably be the way to go, since you'll have a better feel for what's happening to the bearing.
