Broken Pinch Bolt Help

[mike]

I had this not so long ago, the way I resolved it was…..

1.Snap the head off (you’ve done that bit already)
2.Heat the bolt “tube” to a nice red colour
3.Use an impact wrench on the remaining nut which will pull the remains of the bolt out, with spacers once you run out of thread.

On the other side I ran out of gas and didn’t get it hot enough so the impact wrench sheared the bolt. Then the whole lot had to come off, once in the vice I used a saw (might have been grinder) to cut sections out of the bolt leaving smaller bits which are easier to remove. ie cut 10mm out of the bolt, drift the remaining bit inwards so you close the 10mm gap up, cut again to get another 10mm gap and repeat. Once the two end bits are out you can do the same for the middle bit. It’s a pain but you’ll get there eventually.
