how do i get a bolt seized inside those metal bushing sleeves out? i already cut off the head of the bolt. but it wont budge.

 

what bolt/bushing sleeve are you talking about?

 

What jadmt wrote. In general, there are a variety of techniques to remove a sezied/stripped/broken bolt, and it depends a great deal on where it's at, how it's damaged, and how accessible it is. It looks like you may have posted a picture because of the space your post takes, but it's not showing to me. Regardless, here are some general ideas that may help ...

• Soak it with PBlaster. Let that work its way in for a while, and maybe even give it a couple extra squirts during that time.
• Use an "easy-out". With these you drill a small hole in the center of the bolt, large enough to fit the easy-out. Then you thread the easy-out into that hole (it's reverse threaded). As you thread it in, when it bottoms out, continue gently turning and it should (hopefully!) start to back out the stubborn bolt. Be very careful, especially with smaller easy-outs. I use "easy-out" generically--there are actually quite a variety of them and I don't recommend any in particular. They are very, very hard metal, quite a bit more brittle than the bolt, and if you break one, very tough to get out. Buy a quality product, not some cheap import.
• Grind a horizontal line across the top of the bolt--basically making it a slot for a screwdriver. Then use a screwdriver to back out the bolt. If you damage the area around the bolt hole, it may be necessary to fill that in with weld, then use a tap or thread restorer to fix the damage to the threads.
• Weld something to the top of the stubborn bolt that you can grap with pliers, wrench, whatever. Then use the appropriate tool to turn the bolt out.
• If the bolt is stripped and accessible from the backside, it may prove possible to drive it out with a pin punch.
• If the hole threads were damaged, use a heli-coil set to repair: Drill a larger hole, tap, then insert the appropriate heli-coil.

 

X2 What location are you working on. If you cut the head off I would think you are trying to push through the sleeve/bushing and not working on a threaded hole. In which case it probably isn't 'seized' but a force of weight or twist of a component needs to be eliminated.
After all is figured out make certain any damage caused by cutting off the bolt head is repaired or we'll be hearing about the rust problems to follow.

I would STRONGLY suggest you stay away from easy-out type extractors. Being a machinist, I have people bring me tons of real expensive parts with broken easy-outs in them. Easy-outs cannot be drilled out once they break. They are as hard or harder than drill bits. Essentially, you ruin whatever part you're trying to fix. If you cannot extract the bolt using Mark's other suggestions, which are all good, I suggest you seek professional help. Yeah, it's going to cost you but it's better than ruining something that's going to cost an arm and a leg. Good luck with your project.

 

Assuming you're talking about a bolt that's seized to a metal sleeve in a rubber or poly type bushing, I don't know of a way without separating the sleeve from the bushing, which effectively damages the bushing. Quite likely, you will have to remove the entire bushing from it's outer casing and replace it. Maybe someone knows another trick for this...
