Looks like wax did it

Sunday late afternoon I got done raking some second cut and one of the U-joints on the back of my old JD 640 fell apart. Yesterday AM I pulled it up to the shop to pull the drive shaft out and what a battle it gave me. I finally resorted to my flame wrench, and it still took three heat cycles. After the 3rd heat up and a few good hammer blows it was still not moving. I got my wax and applied it for 15 to 30 mins, and then the BFH started to move it. It is possible that it was going to give up anyway, but this is my second situation like this.
 
If I suspect a battle, the flame wrench comes out, and the candle wax. I've still twisted off a few things, but amazed at the difference between heat and wax and no heat and penetrating oil. I would not be with out the oxy/acetalyn torch. gobble

It appears that one factor is the incompatability of heat and penetrating oil. At a temp where the oil will instantly evaporate the wax says liquid.
 
When I first got my current feed grinder, it had sat outside a few years, and the PTO shaft was rusted tight. It took hours of soaking and heating to get it to slide apart without beating the U-joint ears out of round. Lots of time followed to wire brush the shaft and splines, even a custom-built long-reach drill mounted brush.

Fast forward to Saturday, I go to hook up to the grinder and the shaft won't move again!! GRRR. I got it to extend just enough to hook up and get the load ground. When finished, I unhooked the grinder but left the shaft on, and used the tractor to "gently " pull them apart. I really didn't want to destroy the back end of the tractor, or bend the jack over, so it was pretty light pressure. It came all the way out eventually, along with a bunch of corn and the remnants of a mouse nest!! Must be the mouse urine was acidic enough to rust the splines inside the casing. It's out now, and getting cleaned again. Looking for some steel wool/caulking to block the entry next time.

No acid in urine, it is urea which is corrosive.
