Taking one of the nuts off, the stud broke.
I welded a nut to the end of the stud so I could get a socket on it, but she doesn't want to turn. Feels like it will break again. So I've been hitting the stud with PB Blaster. I could heat it with a torch. Hopefully it will come loose, but I may end up having to drill the thing out and tap the hole for a step stud. Grr, right before WCR (IMG:style_emoticons/default/headbang.gif) Any suggestions? |

Arr! The bastard put up a fight, but I won. Well, at least the first battle so far...
So, welding the nut to the stud didn't end up working... It just twisted off. That stud was stuck tight. And being so small, I couldn't get enough welding surface to have any success with the welded nut idea. So.... Welded a piece of flatbar along side the stud. That way I could get a good weld on both sides of the stud to the flatbar and get some real power on it. A crescent wrench can grab the flatbar.... Then my only problem would be if it just broke the stud again. I was prepared to drill and tap at that point. BUT... First, use technique... Heated the head around the stud with a mapp gas torch. Sprayed PB Blaster at the threads. Started to twist... Not just try and unscrew the thing - it's seized too tight for that. But... back and forth a little (as Len mentioned). It began to move. Each time, as starting to unscrew more it would bind more. So, more heat, more PB Blaster, more twisting back and forth. As it freed up, kept working it out. Done! Now on to installing new studs. |
