Have you tried spraying a lubricant like PB BLASTER down the thread shaft? Is the top half bottomed out on the bottom half? There is a grease Zerk on the adjusting arm/leveling crank to keep the threads lubed. The problem with grease is it is a magnet for dirt. Once dirt gets onto threads, it makes it hard to crank. If the crank hasn't been greased in along time, the grease has hardened and turned to wax. A tell-tale sign of that is when you try and pump grease in with a grease gun, you get resistance and it won't pump. Try spraying a penetrant oil onto the thread shaft several times a day and then maybe use a good pair of Vise Grips and/or a large set of Channel Locks to try and separate the two halves. I'd try this before attempting to remove the entire lift arm. I do not like whacking things with a hammer -a good way to crack or break things. Propane is not hot enough to heat steel castings. You'd need a good welders torch.
