52 A

Coach Ag. · Oct 22, 2009

Ok I have a rather difficult problem. I am an ag teacher and decided to restore a 52 model A in class which has gone well till today. We were removeing the radiator asy. and when removing the nuts from the engine block one of the studs broke off where the nut had rusted together. Anyone have any ideas or suggestions on fixing it?

where are you at?

Is there still some stud sticking out from where it threads into?

If so you're on easy street. Just take a nut larger than the stud, slip it down over the remaining portion and weld it on. There are certain things to be careful about, of which you are most likely already aware.

Good luck, Sam

Precisely the lessons that need to be learned. Restorations rarely happen without a number of broken bolts/studs.
Heat the stud with a torch and let it cool.
If there is some still sticking out, put a larger nut over it and weld it on.
Drill it out and retap the hole.
You might try drilling a hole in the stud and using an "easy" out just to show the class how they don't work worth a hoot.

52 A what. Farmall JD or what. That said you might be able to weld a washer and a nut on it and then be able to remove it. BTDT on an Allis C when I need to change the thermostat and broke both blots off. Welded the washer on then a nut let cool a little bit and out they both came with very little trouble

If you can weld a nut on it, after the nut is welded and has cooled a bit, put the wrench on the nut and lightly twist on the nut back-and-forth just a little bit and gradually twist with a little more pressure as you are twisting back-and-forth. Sometimes I use a vise grip instead of a wrench because the vise grip is absolutely tight on the nut and I have a better feel for whether the stud is coming loose or not. Sometimes the stud turns right out and sometimes it turns a little and stops. You just have to take your time and not get too anxious about it. If you just put the wrench or vise grip on it and start turning it like you would a normal bolt you might twist off the stud again, only it'll be deeper in the casting and harder to get a weld on the next time.BTDT.

If you have to drill it, drill a small hole directly in the center first, but don't drill clear through the bolt and into the water jacket. Then try a left hand bit that's bigger than the first bit. The left hand bit will grab the bolt better if it's merely enlarging the first hole. Good luck and take your time. Jim

You say one of the nuts from the engine block. Were you trying to remove the head or were you trying to remove the block from the crankcase? If either complete the remove process and there should be plenty of stud left to get a hold on for removal. When you try to remove it use HEAT.

Ok guys I appriciate the help. I was going to try the easy out and saw a friend that had a had a craftsman bolt kit. Looks like a dye set but you tap it on with a hammer and turn it off with a wrench. But thanks for the advice. And by the way it a JD
