The outer shell is pressed on over the two big o-rings- pull the right angle tab back- and use another old shell to place over the top and bridge it with a good piece of oak two by four and give it one good wack with a 10 pound hammer and it pops right off- then I sand down all the sealing surfaces and clean them and re-oil them and put the shell back on and line up the other side of the shell and put the oak bridge across it and one good wack and the shell is back on...pretty easy if you have an old shell......already off the compressor.......
