Hey there guys- my first post although if overcome some issues reviewing earlier posts.

Rebuilding a ‘71 350 K3. Learning by making mistakes. Today while installing fork seals (which I achieved) I thought disassembly was achieved by removing the small Phillips head screw at the underside of the fork where it sits on the axel.
I had to use an impact driver to lose that screw - seems that was a stupid idea- the screw broke free but now turns freely without coming out.

I don’t know what I’ve damaged but I can tell that this fail will cause a leak - what is the solution… is there further disassembly still required or should I have that place where the screw is welded over; I’m at a loss - can anyone help?

Screw doesn't need to come out to take apart the early forks. Remove the fork tube and you will need to fashion a tool to hold the piece that the screw goes into while you remove the screw. Clean the screw and tube up. There should be a copper compression washer so don't lose it. You can use a small amount of sealant on the screw. Using the tool you have made hold the interior piece while tightening the screw .... I would use a battery powered impact.

If you have a battery powered impact you may get lucky by short power pulses on the screw while it is assembled by it would be a shot in the dark. Not going to work by hand.
