I got it, here is how you do it. The steps are to work with the female bolt first before the male, the female side is the side that has the non serrated blade, which I recommend taping so you don't cut yourself.
1) Use a small C clamp to hold the plier as shown in the picture 1, you have to open it this way to get the plier hole best aligned.
2) Then take a wood dowel about 3/16" and jam it in the hole until it gets past the first spring and into the plier head. This aligns the holes.
3) Then take your needle nose and depress the leaf spring that touches the plier head so that it is flush with the plier head by grabbing the edge of the spring and the edge of the middle of the plier head's back, hard to explain but theres a raised edge to the plier's back where it sits between the two inner springs.
4) You remove the wood dowel and then jam the female sex bolt (
) / shoulder bolt into the hole where the wood dowel was, this will look like picture 1.
5) Now you are at picture 2, use a c clamp to hold the sides together.
6) put a tiny bit of loctite on the male threaded bolt, then insert into the file and then tighten the screws also as shown in picture 2.
7) fold the blade and the file into the tool.
8 ) adjust the tension with the two screws until desirably stiff.
9) i heated it with a hair dryer to warm the loctite and then oiled it, the heat helps the oil flow in.
10) open and close it a few times to move the oil around then wipe off the excess
Time wasted about 4 hours.
. Now that I know the secret I could do it in about 5 minutes.
Also I have to applaud leatherman on their insanely tight tolerances! I tightened it up and its perfect now but the reassembly is so tricky I strongly recommend the average person NOT take it apart.
