How To Disassemble Conklinetta Sr?

[SpecTP]

I posted this in the USA pens forum, but it didn't get any response. I'm reposting here in the hopes that there is some knowlegeable individual who can help me. I have a Conklinetta Sr that has a leak somewhere. I'm not sure if it's through the feed, but every time I ink it up and use it, my fingertips are always stained. I have tried to disassemble it but I can not figure out how to access the sac.

The sac is in the barrel assembly (the top piece). You removed the nib unit from the section and, in spite of the projection for piercing cartridges, there really is a sac in that barrel. You need to put the nib unit back in the section at the front of the barrel and remove the entire section as you would for a vintage pen. What you will probably find is the sac has separated from the section nipple. For whatever reason the new Conklins with sacs (the Conklinetta and all the Crescents) attach them to the section with a wire instead of shellac. Those wires have a tendency to come loose, allowing the sac to leak at that connection. Your pen is probably leaking from the joint between the section and the barrel. Mine did the same thing the first time I filled it (I also had ink coming out of the hole for the filling button) and a detached sac was the culprit. If the pen is still under warranty contact YAFA about sending it back. Or you can try to take the section off yourself and reconnect the wire. Although I have resacced hundreds of pens I sent mine back rather than risk voiding the warranty with my own repair.

 

Good luck.

My problem is how to remove the section from the rest of the barrel. I don't see a seam where the threads are located. I've tried a bit of force to twist the section, but it's not working. That's why I was thinking that the barrel + section was one piece and the only way to access the sac was removing the nib unit. It may be that the section is adhered to the barrel and not easily removed without applying some heat or other method.

There is a seam there. The section is screwed into the barrel. Mine comes out with a little twist using fingers, no section pliers required.
