Have some rusted parts from a disk that need to be freed. I tried pb blaster, liquid wrench, and still they are stuck, real stuck. What is involved with torching it to free the part? Is it guaranteed to free it? The part is a turnbuckle as well as bolts.

On bolts that I could not heat because of their proximity to combustibles, I have found that sometimes several hard hammer blows can jar the rust loose enought to wrench it.

After getting it red hot with an oxy torch, apply some candle wax as it cools. Wax will seep down between the threads and loosen it. Penetrates much better than oil.

 This is my usual process in reply to tractormiallis, 12-21-2006 17:57:00  
Usually in this order, wrench, bigger wrench, bigger wrench with pipe (try not to break anything at this point), heat with torch. If all this has failed then the part is torched off and I feel better. Then I can figure out how I'm going to fix it back. If it's something that's big and probably difficult to replace and I don't need it right this minute I usually try soaking the PB blaster in several days. With patience I have been very successful. It's when my patience is gone that things start to get ugly. I have definitely burned off my share of fairly expensive parts, but I try to have more patience nowadays. You really should be able to get the turnbuckle and bolts loose with the heat. If the bolts can be replaced I usually just torch them and save myself the aggravation. Have fun.

One thing you can try is getting just the outside hot and then while its hot hose it with PB of some type of oil. The heat will draw the oil into all the little crevacise. I think I spelled that wrong

U bolts arent too expensive, I usually just cut the ubolt and replace after a few times of heating and putting sockets and cheater bars on them. Then twisting them off anyway.

Heat them up real good but not to the point of cutting them. Then either let them cool on there own or pour some tranny fluid etc. on them to help cool them plus it helps get the fluid down deeper to do more good. Even then you may or may not get them loosen up. Also work them back and fore if you do get them to turn or you may brake parts
