Help! How do I remove a copper coil from a compressor?

I have a big commercial compressor. I have disassembled it but can't get copper coils out of metal housing. Anyone have a trick to get them out? I don't know how to add photos. This compressor is a big o e that bolts together

Some people use a cut off wheel on a grinder and split the casing in half to pull the motor out. There is an art to this to save your blade. I use a torch to split the case in half. It looks like you have all of the oil out of it, first safety procedure. The ones made from cast can sometimes be broken with a sledge hammer.

Until the last year I did not bother and sold the entire unit as an electrical motor. Since prices have been low I started experimenting based on information provided on this site. My system is to split the casing with a torch, put motor in vise, use cut off blade to cut off one end of winding, punch and small hammer to push winding through top opening, flip motor in vise, and remove rest of winding using pry bar, pliers and punch. Some would not believe how quickly this can be done, so I will not post the amount of time I invest in one.

If you do a search in the upper right corner on scraping electrical motors, you will see some of the techniques others use. My way is not the right way, just the way I have found success.

Good luck and tell us more about yourself.

This isn't the typical compressor.i generally cut into them with a grinder but that's not Gona work here. Might try hitting with a sledge.

Beings it looks to be cast, how about score it with the grinder then taking a sledge hammer to it??
