T case bolt stuck BAD 89 FJ62

[julianramirez1005]

Anybody else have these bolts get seized in their case as bad I am experiencing? Suggestions? This is after days of soaking in liquid wrench and a few attempts at removing.

Thought I felt it moving so I kept pushing and here we are.

Do you have access to a welder? Weld a nut to it and it should come out. There’s a good amount of it sticking out so you’re lucky there. I like to use the same size nut or a size bigger. Grind out the threads with a carbide burr. Put it over the broken bolt and weld it up. Let it cool naturally and slowly move it back and forth. I do it like that frequently with success. If no welder you might be able to put a little heat to it with mapp gas or propane and get some vice grips on it. Heat it until your spit balls up and sizzles on it. Be very careful not to over heat though, very careful.

100% agree, I’ve never had success with easy outs. Mig welder and a nut

And also hold the nut with the ground clamp of the welder. Do not ground to the housing.

Ok heard. Yeah I do have a welder, gonna attempt a snap on extractor my dad swears by and then give that a go.

Stud extractors are for when you snap a bolt while tightening. They are not for removing seized studs. Either weld onto it (having the hardened stud extractor in there won't help) or drill it perfectly centrally, and drill out until the shank of the bolt is gone and you can get the threads out. Worst case, drill it out and put a thread insert in there.

Noted, thanks

At this point, you have three options: Weld something to it, sit there for a lonnngg time with a carbide grinding bit, or bring it to a machine shop.

If you go the weld route, I recommend putting a washer down first, and then welding the washer to the broken bolt and extractor. Then weld a nut to the washer. It's much easier to get a better weld that way.

If the weld technique does not work, you will have to bring it to a machine shop or grind it out with carbide. You will not be able to drill the extractor out - it's essentially just as hard as any drill bit you may have. So you will have to use a carbide grinding bit in a die grinder (or dremel) and slowly grind the extractor out. If you're feeling confident, you could probably slowly grind the inside of the bolt away to the point where you can just yank it out.

If that doesn't work, you will have to bring it to a machine shop, and they will use carbide endmills or a plunge EDM and remove the extractor.

Got them out. First one I drilled out from the other side until I hit the extractor and punched it out. Then I drilled bigger and bigger until there was a thin layer of bolt left. Then when stepping up the size it broke the bolt loose and i unscrewed it from the back. 60% of the threads are fine and the other 40 is a little wider than factory but I think it’s fine.

Went with the weld method on the second. Let it cool and worked it back and forth until it came out clean.

Thanks for the help
