Disassembling Eversharp 10000 Word Section/nib/feed

[PDW]

I have a 10000 word pen that is good to look at, but it dries up within minutes of attaching a cartridge. I've flushed it and soaked it in ammonia solution enough times to know that it really needs taking apart and a complete clean, and possibly a nib flossing and tine gap adjustment.

 

Has anyone disassembled the nib and feed from the section on this model? It looks as though the nib/feed ought to push out towards the back of the section but I'd like to hear of experiences before I try it myself and possibly break something in the plastics.

 

Edit: I've had another look at the pen, and the nib has 'wings' which are wider than the hole in the section so it cannot come off by being pushed in. Using a good light I can see the black cartridge piercer at the back of the feed sticking out of a hole in the section moulding inside the pen, so it looks as though it ought to come off forward as well. But does it just push out from the back or is it a screw or other non-friction fit?

Answer to this question for future reference.

 

After a dip in the ultrasonic cleaner, I put my fingernails behind the wings on the nib and pulled forward, almost-but-not-quite gently. The tubular nib and the long feed (somewhat like a P45's) came out, leaving the cartridge piercer tube in the section. The nib slides off the feed.

 

To put it back, put the nib back on the feed and push the assembly back where it came from.

A-mazing. As someone who just realized he needs to own a couple three of these pens, so grateful for my forbears with the courage to explore repair and maintenance.
