The heat has to be quick and localized so the aluminum is not damaged. I would imagine that the shaft could be pressed out of the lower tripleclamps (and then pressed back in) to lever the race up/off but that might be a last resort.

mcman56 Posted February 24, 2009 Report Share Posted February 24, 2009 I have used carbide end mills in a milling machine to cut a groove in the inner race. Once the wall thickness is very thin, it will split with a little force. It was surprising how easy the races machine with carbide tools.

Once the wall thickness is very thin, it will split with a little force. It was surprising how easy the races machine with carbide tools. I was surprised how easily it split too, I ground it down with a small cutter on my air compressor, then when it was thin, used the flat edge id ground out to get a grip on it. and bobs your real dad, it cracked =] Thanks for the help Tom Quote Link to comment Share on other sites More sharing options...
