Allen head bolt stripped in rear bearing cassette , how can I get them out ?
Only do this in aluminum or cast iron because the weld will not stick. Also as soon as you are done welding, pour lots of water on the red hot nut. It will shrink the bolt enough to loosen it up. I have done this a lot of times. Works better than easy outs.get a nut larger than the stripped allen head and weld it to thru the center,,, just get correct socket size of the nut and spin it out...it works most of the time,,,,
