You probably done want to hear this, but how about a hammer??

O.K., will it feel better to call it a mallet?

Default Protect those studs before applying a hammer

Before any hammering is done on them, make a tool to protect those studs. Take a piece of 1.5" or 2" diameter round aluminum stock. Cut it about 3 inches long. Now drill (about 1" deep) and tap (a bottom tap works best) into one end so that you can screw this protective "cap" over the stud to be hammered on. This way you won't damage the ends of the studs.

The assembler has to use a hammer to install the studs. You will need to use a hammer to remove them. Do not hammer directly on the threaded end of the stud unless you plan on replacing them. Also be sure you pick the thru bolts to hammer on and not the case mounted bolts.

I have a tool I made exactly as Charlie describes, except I made mine from steel. You drive the thru bolts down with a hammer, and finish driving them thru with a brass drift.

There is a .000 to .003 interference fit for the studs, and really the only way to check the fit is by how easy they drive thru the case halves. The middle of the stud is tapered, so you only have to drive them about 1-1/2" or so before they will fall out. If you find any loose ECI makes oversize studs. Sometimes swapping the studs between locations will take care of any loose fits.

Default it is separated

I just separated the case. I removed the 4 through bolts by putting large washers on the studs and then drawing them out with the nut that goes on the stud. They were tight but came out fairly easily. As soon as I pulled the four studs out I tapped the case with a rubber mallet and it essentially separted with one light tap. The seal on the nose of the engine held the nose of the engine together. It required some coaxing. I just used something soft to pull down on the seal once I had room. If you have to do this remember the rear through bolts are not really through bolts. They are anchored or screwed into one side of the engine. No need to remove them. Thanks for all the help.
