430 deisel stuck crank and pistons scrap or not ???

Gear shift cover assembly, choke cable, light switch and generator and maybe fenders, I will have to compare numbers.

DCTom and others have described taking an old spark plug and breaking out the ceramic and welding a pipe nipple or other similar threaded device so you can hook a hydraulic pump to it to get pressure on top of the piston. I would do this first before I would do the burning gas trick. Gasoline is very explosive and its explosive fumes make this a very dangerous operation.

I would fashion the hydraulic pressure adapter and use another hydraulic source like another tractor or maybe you have a small hydrauilc hand pump.

Drop the pan and crank. (You will do this anyway on a rebuild) then screw in your spark plug adapter and start adding pressure on top of the piston. This should break them free. Same proceudure for all pistons. Obviously you will need to put the head back on to do this, I am guessing you still have the reworked head off. See if you can get this done with the old head gasket and liberal coating of Permatex to help the old gasket seal for this operation. This way you won't ruin a new head gasket trying to free up pistons.

If Tom reads this he can give better intructions than I, I am just going from memory of his answer to an old post.
