Pelikan M(2/)400 Cap + Pelikan 140 (?) Barrel/section

[teuneu]

Hello people!

I was wondering whether any of you could tell me how well a Pelikan 140 barrel/section with a Pelikan m200/m400 (I don't know exactly what it is) connects? I can buy a Pelikan which clearly has the back end of a 140 (or 400NN), but a different cap (not the pointy cap like the 400NN, but the newer m400). Since the price is half the normal price and I don't really mind the 'completeness', since it is a writing instrument. Thus, it should be used. As long as the parts work together well, I'm fine with it. I have a 140 already and like the nibs a lot.
Thanks a lot in advance!

Best regards,

 

Toni

400nn cap on a 140...not well fitting. The cap threads only turn 1/3 of a turn. Feels a bit loose.

 

A M400-'90's fits better....no big difference. Same lots of turn on both pens.

 

The 400nn's cap fits even worse on the M400 than the 140.

Thanks a lot for the answer! It is not a 400NN cap (not pointy), but a m400 cap, I think. Thanks again.

I just received the pen. I bought it for 17.50 euros and I think I have a 400NN in my hands now (based on my ownership of a 140, which feels and is a bit smaller). It contains a '90 m400 cap. I tried my 140 cap on the pen and it does ~ 1 rotation (maybe a 300 then?). The barrels is approx. 5 - 7 mm longer than the 140. Does anybody have an idea? Purely based on amount of rotations for both pens, the best combination would be to interchange caps (but I don't want that for the 140).

It contains a KF nib in relatively good condition (I have to clean it, center the feed). The piston filler seems to be stuck, since I can screw off the piston knob. I have no idea how easy this is to repair (and how expensive, student alert ;-)).
The inside looks clean, since I can look easily through it. I think this is an old pen, cleaned from the inside and stored. I first have to clean the nib and feed and then start to think what to do with the piston filler system.
Until now it is an interesting buy for me. I know have to look for a 400/300/<whatever it is> cap, since the m400 cap won't go very far, with respect to rotation, as stated by Mr. Olson above.

Soak the whole pen in water and see if you can get the piston to move.

I just did a bout with a 400nn with a cap that had bad threads.

When I measured the barrel it turns out that Pelikan uses a 4 split thread.

What I think happened is someone tried to put the Pelican cap on a Parker pen.

The Parker has a 3 split thread and the mismatch damaged the threads.

I needed a chase tool and ended up making one.

I made it based on the barrel threads of the 400nn. 10.8mm diameter X .7mm pitch.

Since it is a 4 split, it becomes 2.8mm pitch.

I made the tool and used it to clean up the threads, and am happy to say it worked.

 

During this adventure I thought about the split thread concept, and it is quite brilliant.

Reduces the chance of cross threading, gives you more thread engagement with less turns. If your cap turns ¼ turn it is effectively engaging a full turn of thread. it makes it faster to cap and uncap.

It also might explain why you find your 400 floating around in your shirt pocket. It is the pitch of the thread that determines the retention friction. Less pitch, less friction, the easier it comes off.

I have had mine come off but I call that... User error!

Funny fact,

If you take your 400nn and put your finger nail in the thread and slowly turn the pen, tracking a single thread, you will find there is only one turn.http://www.maryhatay.com/Mark/Mark-Mixer/i-rc7WzvD/0/M/Cap%20tap-M.jpg

 

Well I love my Pelikan, it’s my favorite daily writer.
