I have a broken starter bolt in a '95 Ford auto trans case I need to remove. I have a nut welded to the end of it and it's been soaking in Kroil for a few days, still no love. The hole is open ended, so I believe the bolt is corroded fast in the tapped hole from road deicer and salt. Next step is to heat the casting to try to release things. It's in a awkward place in a truck and access is limited from underneath, of course. I plan to heat the casting with a torch, and want to use a temp gun to gauge how hot to make it, because I can't just hover my hand over the case to feel the temp and guess at it. If I screw up the case I'll make a major job out of a minor one. Drilling it out would be very difficult because of the location so this is my best hope.
How hot can I make the cast aluminum case without taking all the strength out of it afterwards? I know certain cast heads have a few hundred degree limit before they loose a lot of stability, is this also the case here? In the past I just heated and estimated by feel, I need some digital data for this job.
