Disassembly of Parker 25's cap

[AceNinja]

Hi all, I've looking up and down online for ways to disassemble the cap of my Parker 25 fountain pen.  You see, the capping 'feel' of the pen feels a bit loose.  And the pen keep evaporating my ink.   For example I have a full ink of parker cartridge.  After maybe 1-2 months of barely using it, I can find the ink level is almost empty.  And the ink colour is super duper dark on page.  It doesn't dries out, still wrote on the first stroke, but the ink still evaporated.

 

So I've been thinking want to disassemble the cap in order to remove the inner cap.  To see if something can be done to improve the cap seal.  But I seems to can't find any info on it.  Also I'm not sure if there's even a inner cap for this pen, still in my research phase.

I have no experience with that but according to his FPN thread you can push down the coloured plastic tassie/button on top of the cap and that should release the inner cap:

AceNinja,

 

After disassembly, you may find a hole in the inner cap. Some have, others don't. If it's there, you can try to cover it with a small piece of cling film to see if that solves your problem. Chance is that closing the hole results in your pen pulling out the inner cap if it's not tight in the cap. I guess the hole is intended to prevent just that, but since other P25 without that hole uncap fine, the hole might be superfluous.

Thanks for your info!  really great!  and yup its relatively easy!  And yes I saw the hole you're talking about.  I think maybe I'll just cover up that hole, and also try to make the mouth of the inner cap tighter with some cellophane tape (I did that with Safari's inner cap with great results).  Now I'll report back later if this does helps on my issue.  Gonna be a while cause its testing by the months.

Thanks for the pictures, these are helpful for future reference. Does the inner cap alone (not mounted in the cap) clicks snugly onto the pen or is it also a loose fit?

[Shaughn]

Joss, inside the inner cap are three small notches that should click fairly snug in the rim of the metal band on the shell.

Thanks. My thought was that if the inner cap still snug fits by itself than the encountered problem may arise from the outer cap.
