How do you take apart a Pelikan Go pen? Mine is leaking from the barrel, and I suspect it's coming from the piston knob. The leak showed up outside the ink window when I flushed and cleaned the pen.

I've gotten as far as taking off the nib, but I wouldn't want to take the piston without expert advice. Any suggestions?

I didn't even know you could take off the nib! Could you explain how?

That's my only issue with the Go, which is otherwise a wonderful pen - they seem hard to disassemble and flush.

There is absolutely no reason to disassemble a Pelikan GO to flush it....
You flush it out just like you would any other piston filler, but filling and emptying with clear cool water....

I know you can do that, and I do, but when I change colours completely - like from red to green, I often take out the nib and soak it separately; with cartridge fillers (like the Pelikano) I'll sometimes soak the nib section and flush it separately as well. It just bugs me that I can't do the same thing with the Go. Yes, I realize this is compulsive behaviour

Dry the nib and your fingers with a thick paper towel. Twist the nib a little bit using your fingers and pull when there's a little play. If your fingers slide off, you can use a dry paper towel to grip it.

Thanks gregoron. I hope you get an answer to your original question. I'm afraid I'm as much in the dark as you are on that one.
