Use an electric fan heater. Set it up to blow into the front of the crankcase from a minimal distance. Leave for 20 to 30 minutes. No flames, nothing to hold, no risk of overheating anything and you'll be amazed not only how hot the crankcase gets but how easily the bearings come out. As said above, don't glue them in when you reassemble.
