Need Help With Disassembling Waterman Section

[doyleniemann]

I have two Waterman E’Talon pens, which I have really enjoyed, plus an extra section and point. Problem is they all leak around the half ring clutch that secures the cap. I was able to dissemble one of the sections and believe the problem is the o-ring that fits above that ring (it’s red/orange). I’m thinking of using silicone to try to create a seal there.

 

But that’s not the problem that is driving me crazy. I can’t dissemble either of the two other sections. I’ve tried hot water and physical pulling, but it won’t com apart. From the section I have apart, I know they do not screw, but push on. I am assuming there’s some kind of adhesive involved.

To clarify, I can pull out the nib and feed, but the plastic piece that hold then won’t come out from the black plastic grip section. That, in turn, will not pull out of the metal piece that the barrel screws on to and that secures the offending clutch half ring.

Any ideas about loosening things up?
