incredibly stuck bolt

An incredibly stuck fender / stabilizer brkt bolt has apparently formed a molecular bond with the rear axle housing (MF35). (see photo)

It doesn't respond to beating with a sledgehammer, twisting with a wrench, driving in a wedge, or cussing. Is there a way to hook a lightning rod to one of these?

1. Grind bolt end where it's been hammered so it is smaller than the hole.
2. Jack up tractor 1/2", put another jackstand under bolt, and lower slowly.
3. Soak in PB Blaster
4. Go away for the weekend.
5. heat with a torch until PB starts to smoke.
6. Wait 2 minutes and apply more PB. Rap smartly with hammer.
7. Repeat 5,6,7 until totally frustrated. Then repeat 3 and 4.

You can get them out without heat but it will take a long time. If you decide to drill cut the bottom of the bolt as close to the casting as possible first, and be sure to center punch. Also, once you have drilled up past the lower casting ear, try the heating trick again.

Stuck bolts stink.

Think I'll have to try that ammonia trick that was suggested.

Set up your hydraulic jack on that side to jack on the bottom of the bolt. Leave your jack stand in place or better yet, place some blocking under the axle to be safe. Jack the axle up several inches where there's plenty of weight on the bolt. Then apply some heat to the housing pad around the bolt--try your best to keep the heat off the bolt. Once you get the housing heated up a little and the bolt doesn't move up (actually the rear axle will move down to the blocking) try hitting the housing with a 2 # maul with sharp raps. If you need more power, use an 8 or 10 # maul, but I would recommend an oak block to soften the blows--don't want to crack any housings here...If that doesn't work then make two cuts in the bolt in the center area so that there's at least a 1" gap. The lower half should then push up and then you'll only have the top half to deal with. Now you can place a pin through the lower hole and set up the jacking method the same way. As a last resort you can always burn the bolt out.

Another (slower) method is to drill the bolt out but that'll be a lot of work. We won't go there unless you want to...

Say a prayer or two to keep up your patience and ask for some wisdom too...

later days mate,
