Here is the way I do it.
To get the rear cap off you need to loosen the four setscrews untill they are almost out of the manifold. Then just gently pull the rear cap off with a bit of a twist past the internal O-ring.
At this point I recomend that you pull the internal manifold O-ring out and remove all four setscrews. Clean out the setscrew threads and the rear chamber of the manifold along with the rear cap threads and O-ring groove with lacquer thinner letting them all dry fully. I did this the first time because I found some aluminum chips in the grease on my rear cap and I'm paranoid. Use half a drop of blue Loctite on each setscrew and start the setscrews in the manifold half way in. Clean and lightly relube the O-ring but only reuse it if it's not visibly damaged in anyway. Install the rear cap gently pressing the cap in as you rotate it to get it past the internal O-ring.
Once the rear cap will seat fully (which indicates that the O-ring is seated in the rear cap O-ring groove), turn each setscrew in one at a time stopping when the rear cap starts to feel at all tighter. Repeat the setscrew tightening for the three setscrews at the 9:00, 12:00 and 3:00 positions. The fourth setscrew at the 6:00 position is bit longer than the others and needs to extend out of the manifold slightly to help locate the bolt/manifold assembly. The rear cap needs to turn smoothly and freely to be assembled correctly.
While the four manifold setscrews used to retain the rear cap are captive once the bolt/manifold assembly is installed there is the potential for the setscrews to work their way out and lock the bolt/manifold assembly in the bore of the marker body. This is the reason I suggest a touch of removable Loctite on the manifold setscrews to keep them from coming out and scoring or locking the bolt/manifold in the body.
Hope this helps!
