I have the FSM. The bolt on the bottom has a Phillips head, but won’t come all the way out. I’ll see if I can get it back right. I tried the slide hammer technique, but maybe just need to try harder!
I just did this...
Meaning I just loosened the JIS screw on the bottom because I though you needed to - but you don't. It has nothing to do with fork disassembly on the CL (external spring) fork.
To get it tightened back down, I cut a piece of heavy duct tape and placed it over the bottom end of the fork tube and punched a hole in the center. When you slide the tube back into the lower the tape will hold the conical piece firm enough to tighten the screw back down. It needs to be snug or it will leak. I tested mine by filling with water overnight, and it was fine.
To remove the conical piece completely, and replace the crush washer, a member here used a 12pt socket on a long extension held tight down on the conical piece for removal and installation.
Once the large snap ring is removed you can remove the tube. You are unseating the seal as you remove the tube - that's where the resistance comes from. There's nothing else holding the tube in the lower.
