yup--heat n freeze!
I've used my wood stove to warm up tapered roller bearings used on Tecumseh cranks--I put the crank in the snowbank or in the freezer for awhile,then after 10 minutes or so when the oil in the bearings start to smoke,you can just drop them right on the cold crankshaft---90% of the time no persuasion from a hammer is ever needed..works slick!..
I find the stove to be a kinder,gentler heat than a torch is,and is less likely to draw the temper out of the bearings..but torches work too,if your carefull..
I once sold a customer a new wheel bearing for a big oil delivery truck --he called me back,said I sold him the wrong one--it was at least .010 smaller in I.D. than the axle it had to slide over..but when I matched the numbers off his old one,they were exact,it WAS the right bearing!..
I had him call Bower/BCA's "Tech Hotline",when I could offer no explanation...
They told him to put the bearing on a 100 watt bulb for 20-30 minutes and try again...after telling them to stuff their 100 watt bulb idea up their butts,he had no better ideas,so he tried it--and much to his suprise, it slid right on!..

..guess those things expand a lot with a little heat...we both learned something that day!..
