I can NOT recommend heating the anything ina oven when doing bearings.
Just warm it with a heater, not a torch.
I have had problems with loose bearing fits after I did this. I can't
prove that it was caused by heating the parts too hot (oven once, propane
torch the second time), but I'll be more careful next time.
That much heat is not needed anyway.
