I don't have a link, but have done it several times. It's pretty straight forward. If you check savvysurvivor he has some photos for some of the tear down.
-Field strip as usual
-Remove safety selector (remember to lift the the retaining spring in the sear assy and shift to one side). This will free the sear assembly.
-Drive hammer assy roll pin out. Then the hammer assy and spring will be free.
To re-assemble, it's handy to have a 3rd hand to compress the hammer spring via the hammer to align the holes while you place a punch, or nail, through the holes. Then drive the roll pin back through, pushing out the punch/nail as you go to maintain alignment.
It's really easier than it sounds with my poor description. I need to make sure I take some step by step photos next time I do this so I can post them. There won't be any small parts or springs flying around when you do this. Now the trigger group, or sear disassembly is another matter......
Hope this helps a bit. If you have any questions, please feel free to ask.
