smash it off 
i cut a small nick with the grinder to start the chisle then split it, same as the actual inner of the bearing,
then yer better off warming the new ones up and they drop on nicely

thers a posh extractor tube but i think thers only 2 in existance now, so yer can sweat them on and off, but dont heat them too much , just enough to get them to drop over the ridge,

when yer order the bits get both bearing and sleave , they dont come off well so need renewing, the sleve is a lot softer than the bearing, it "might" tap on with a tube over the 'arf shaft, but a bit of heat helps

I often see the "warm it up" tip but exactly how much do you warm it and with what? I have a little blow torch - will that be sufficient or are you guys talking about blasting it with something much more heavy duty? Do I warm it for a minute try it and if not repeat or do I heat it until it's glowing??

warm it with oxy acet ideally, by heating it up evenly around the outside till its blue gong on red ish purple the sleve will expand enough to clear the tight tollerence of the half shaft, you only get one go tho, as it cools it bites the shaft tight ! by having a second go your heating the bearing and shaft equaly thus not expanding the collar, its stuck .
you can replace these by nocking them on with a scaffolding tube and first lubing it with clean engine oil , but i usualy found they got stuck half way,
its easy once you have done one, trust me

When you heat a bearing race that HOT you will soften the steel,that is harden steel for wear. only need to heat up to about 350 F for it to slip onto the shaft. heat away from the shaft and use pliers to grip to put on shaft.warm it with oxy acet ideally, by heating it up evenly around the outside till its blue gong on red ish purple the sleve will expand enough to clear the tight tollerence of the half shaft, you only get one go tho, as it cools it bites the shaft tight ! by having a second go your heating the bearing and shaft equaly thus not expanding the collar, its stuck .

what works real well for heating bearing races is a chip fryer. set it at high put the races in do your work and when ready you have the basket to lift the out of the oil real simple and works really good
