This is good practice for the crank pulley bolt lol. Did you get it "red" hot? If youre using propane give up, youll be there forever and risk damaging the bearing from heating everything else up, MAPP is a bit better. when i run into these problems
I get it hot (not red), then spray it with penetrating fluid. repeat a couple times.
make my own penetrating fluid with some ATF and some sort of solvent, it creeps well.
heat it up and melt paraffin wax on it (the threads) it creeps well too.
since that nut is obviously going to have to be replaced, an air hammer on one of the hex's hammering to the left and down..also what might help is hitting the axle nut socket socket dead on, try to break it, hit again repeat..
what worked the last time i had a really stubborn nut was heating it with mapp for a good 5 mins, having the air pressure maxed out and the tank full and short 3 round bursts, also having the gun oiled..after it broke i let it air cool naturally, the threads on the axle wire brushed, they were bad. (oh i also use a 3/4" hose, the regular hoses choke HD air tools it seems)
the crank pulley bolt that gave me hell, i did the jack stand, extensions, the 3 foot breaker bar and a 5 foot pipe,got everything lined up and seated well with a little tension then walked it back, turned over and pulled while sitting down, that break bar looked like an arrow bow, and finally it SNAPPED like a gun shot (i thought something broke besides the bolt) it was a joyous occasion lol.
when you reassemble make sure you take a booger sized dab of grease or antiseize and put a film on the axle threads, youll appreciate it next time..
if things were really bad, id even give using the engine power to break it a try....
or goto a tire place that does semi tires, and have them use their 1" extended anvil gun to break it free,tighten it back down and finish up at home. they should have a 36mm socket too.
