Broken bolt extraction tips

[LongGone2saskatchewan]

I noticed a few broken bolts on my loader frame on my 3316 mahindra. The leftover pieces are located in a very hard to access area and drilling is not really an option. Does anyone have any experience with hard to get bolt extractions. I might try to weld a rod on and see if I can twist out but I would try other things first. Torching isn't a good idea either. Any suggestions would help.

Can you post a few pics so we can see what you mean by "very hard to access" ? Steve

I have always had good luck with welding a nut on whats left of the broken bolt if it is flush or a little higher. But with out any pictures, it is hard to help you out. Do you have a quick attach loader, how hard is it to get things out of your way to access the bolts. Some times tearing down something to make it easier to get to helps you out in the long run on a fix. LUTT

Was checking my loader manual and it doesn't seem too bad to remove the parts. The frame is actually several pieces so it shouldn't be to much trouble. Probably will save time if I Do it the hard way. As always. Thanks to all.

Soak the bolts down with some "Knock 'er Loose" for a few days prior. That has always helped me.

Your welcome, sometimes the hard way really is not the hard way if you know what I mean. LUTT

there is a tool that sears has i used one and was really impressed with it.. it looks like a socket but has a course heft hand bur in it ..if any of the bolts are sticking out this tool will work

lets see pics. if there is no room to drill.. there may be less room for welding.. etc...

The bad thing about welding, something on a broken bolt is that if it does not come out, then you have a real problem because the welded part is going to be harder than heck.
Even if you are going to weld on it soaking it down and center punching it, will help a lot.
Drilling completely threw then putting in a penetrating oil, sometimes I would hook up the welder threw an easy out and let it heat the piece up, then when it cools off, an hour later remove it.
good luck!

the welding usually isn't an issue with hardnedd. if you weld a nut to the stud and it doesn't come out.. the weldment usually snatches a piece off the top of the stud anyway..

I have never had that issue welding a nut on something on countless numbers of equipment that I have done over the years, more than likely, if the bolts are a large size, they wont be hard to get out anyway. LUTT

whether you weld a nut on or drill it for an easy out, try applying some Beeswax around the threads when it is hot. Don't know why but it worked for me.

I have heard of that trick, never have tried it . I think I am gonna have to. LUTT

We weld nuts on as well if its not broken too deep below the face of the base material. The fast heating of the broken bolt really seems to help break it loose too.

When there broken flush then I drill them with Left handed bits. Most of the time they will thread themselves out with the bit.
