Pelikan 400 Piston Mechanism Won't Come Out

Hello, everybody.

 

I am new to Pelikan, and my question concerns removal of the piston mechanism on a Pelikan 400 from the mid 50s.

 

The problem with the pen is that the sleeve in which the piston moves has lost a big piece including nearly half of its threads. The turning knob can therefore not be tightened and the sleeve obviously has to be replaced.The piston irself seems OK and moves effortlessly up and down.

 

From what read on various internet sites, on this 400 model, the mechanism is of the friction fit type and should be removed by pushing with a suitable rod from the front towards the rear after the nib and feed are out. Is this correct, or is it possible that it is threaded?

 

Assumig it is friction fit, I removed the nib/feed asssembly (no problems), gave the barrel a thorough soaking, and then pushed a tight fitting rod into the barrel. I then gave the barrel some heat and tried knocking the piston mechanism out as instructed. But no matter what amount of heat or what amount of knocking, the sleeve sits put.

 

Is it possible that the barrel has shrunk and somehow "bonded" to the sleeve?

 

Any ideas on how to proceed so as not to destroy the barrel in the process?

 

And furthermore, if/when the mechanism comes out, where should one go to purchace a new mechanism? Do other Pelikans, for example 120 or 140 have the same mechanism, or the modern versions?

The piston is out.

 

It just needed a wee bit more force than I dared to use on my first attempts. The plastic (or resin or whatever the Pelikan barrel is made of) is tougher than I thought.

 

Thank you!

 

The next step is to find a new piston assembly.

All the best on finding a new piston assembly.

Maybe you can find one here in the classifieds too.

 

Best,

Arvind.

Best regards,

      I have the Sailor Naginata and some fancy blade nibs coming after 2022 by a number of new workshop from China.  With all my respect, IMHO, they are all (bleep) in doing chinese characters.  Go use a bush, or at least a bush pen.

      It is the reason why I'm so keen on the idea of a personal library — of pens, nibs, inks, paper products, etc. — and spent so much money, as well as time and effort, to “build” it for myself (because I can't simply remember everything, especially as I'm getting older fast) and my wife, so that we can “know”; and, instead of just disposing of what displeased us, or even just not good enough to be “given the time of day” against competition from >500 other pens and >500 other inks for our at

      Agreed.  And I think it’s good to be aware of this early on and think about at the point of buying rather than rationalizing a purchase..

      Alas, one cannot know “good” without some idea of “bad” against which to contrast; and, as one of my former bosses (back when I was in my twenties) used to say, “on the scale of good to bad…”, it's a spectrum, not a dichotomy. Whereas subjectively acceptable (or tolerable) and unacceptable may well be a dichotomy to someone, and finding whether the threshold or cusp between them lies takes experiencing many degrees of less-than-ideal, especially if the decision is somehow influenced by factors o

      I got my first real fountain pen on my 60th birthday and many hundreds of pens later I’ve often thought of what I should’ve known in the beginning. I have many pens, the majority of which have some objectionable feature. If they are too delicate, or can’t be posted, or they are too precious to face losing , still they are users, but only in very limited environments..  I have a big disliking for pens that have the cap jump into the air and fly off. I object to Pens that dry out, or leave blobs o
