If it's any help, I watched a well reputed Bike mechanic change a wheel bearing on my old DR600 once.
He heated up the hub carefully with a blow torch wearing thick glove's, turned the wheel over then the bearing just fell out. He then quickly turned the wheel back over then dropped the new bearing in place before the hub cooled. Job done in minute's, no damage to the hub or wheel & everything all worked fine with no problem's.
