<p>This is just a thought. I always have some liquid nitrogen
around for freeze branding maybe if you could hold something like
a Styrofoam cup around the bolt and fill it with liquid nitrogen,
then wait until the nitrogen is evaporated and the bolt comes
back up to room temp. It is possible this would shrink the bolt
enough to break it loose from the cast iron. If you could lay the
entire assembly flat then stick the bolt through the bottom of a
Styrofoam cup, this might get the bolt cold enough without the
cast iron. just a thought. Before I had liquid nitrogen, I used
liquid propane very carefully.. <br>

The only real reliable solution is to use an acetylene torch(gas
axe). That is the only way to get enough heat to handle on the
mass of the cast iron. An alternative would be to slide the whole
wheel assembly off the axle and take the whole assembly somewhere
where there is adequate heat and air pressure. <br>

Subject: Re: [AT] List quiet!! Everyone OK, or just waterlogged???
<br>
<br>
We are certainly water-logged here in mid-MO. Stuck inside again
today because of rain.<br>
<br>
That said, I have been beating my head up against the brick wall
of rusted lug bolts.<br>
<br>
Both of the tires on my '48 JD A need attention, and one of the
wheels has lost a strip of the bead off the rim, so both need to
come off and visit the tire shop. (I have another rim from which
they can cut pieces of good bead to replace the lost sections.)<br>
<br>
But I am having a heckuva time getting the wheels off. The lug
bolts just don't want to come out. With some penetrant, I go the
first one out OK, but it was obvious that the upper part of the
shank next to the head was eroded, so I became concerned I would
twist one off, but I wasn't cautious enough, for that is exactly
what happened to the second one. (There are 9 on each wheel.)<br>
<br>
Since then, I have used more penetrant, heat, hammering, candle
wax (a tip I got off this list, but I don't remember whose its
was), and an impact wrench. I have managed to extract one more,
but, at this rate, the rubber will rot off before I get them all
out. I know that my compressor does not build up a great deal of
pressure. I have been using propane for the heat; I have bought
MAPP gas for further attempts. I have *not* tried the breaker bar
and cheater again because I am afraid of twisting the rest of them
off. <br>
<br>
Patience is a virtue, but I would like to get the job done this
summer as I need the tractor this fall. <br>
<br>
If anyone has any suggestions, I am all ears.<br>
<br>
