Thanks to everyone who gave me answers to the trans flush, now new problem has come up. Last night I went to take off my wheel on the JD 70 diesel. When I loosened the inside bolts on the axle wedge, one of the heads snapped off. I have about a half inch of the shank sticking out of the center and of course the wedge is now off. Since it does go in the cast center, I don't want to mess it up. What would be the easiest way to take it out?( I have tried heating it and backing it out to no avail)
 
Weld a nut on it, use high amperage to put a lot of heat into it. When the color disapears out of the nut start workin it back and fourth. It may take a few tries.
 
Drill it out. Just try to get it as close to on center as possible. Then you have to get a tap to clean up the threads.
 
Drill through the center and borrow a torch if you don't have one. Cut it on one side then the opposite side and bump it out. The cast iron won't heat up enough to hurt the threads.
Done that many times.

The next best plan is to drill a small hole in it as close to the center as you can then drill the hole bigger in stages till you are almost to the threads. Things drill a lot easier this way. Use an set of torches to burn the last shell of the bolt out. Crank the oxygen presure up to around 50psi so its a fast forcefull cut.
 
Try heating it with a torch and then put a candle on it or just some wax. The wax will suck between the bolt and the threads and make it easier to come out. Don't get nervous about heating the cast. I would heat the cast not the bolt. You are working against yourself by heating the bolt. Then the bolt expands and makes it tighter. If you heat the cast the laws of physics are on your side. the cast should expand a bit and make it move away from your bolt. then put the wax against it and try turning the bolt with a vice grips or tap on it with a chisel.

Hope this helps. Has never failed me yet.
 
The problem with heating the casting is that it is such a large mass you can't heat the area around the bolt fast enough to have a great deal of effect on the stuck bolt. If you heat the bolt by welding a nut on the bolt epands and then shrinks as it cools, the metal in the casting holds the heat longer than the broken bolt and remains in an epanded state while the bolt cools and shrinks. I have even put ice on the nut to srink it faster. The wax trick does does help.
