well according to my take on that photo, the bearing has already moved!
that photo is from bergoroadracer AKA 'takis the greek'. He has so much money that he has one foot in the back door at the factory and this is a mod that was recommended to him by the works.
i don't do it, i bond mine in with a proper bearing agent. the bearings are a VERY tight fit in the cases anyway. on reflection this was done before everyone knew some of the answers.
