Montblanc Chopin 145 Nib Removal

[penhand]

I ran across a Chopin 145 recently that needed some nib work. How does one remove the nib from the Chopin 145? I don't have the pen in my possession, so I can't post pictures. I did a search but couldn't find any information. Thanks.

I have a 144 and would like to know as well.

Here is a great thread (with some pictures) on how to do the removal on a MB 144.

Can someone verify that the 145 is identical?

The 145 isn't identical to the 144. Nibs are not easily removable from any Mb FP's. You need a special tool, plus you risk breaking the feed or the nib or both. It's best to leave it to an expert

My recollection is that the 145 nib and feed pull straight out together. I just wiggled it a tiny bit while pulling.

Thanks, PenHand. I have wanted to know that for years.

Hi,

 

It's odd, but I've seen 20+ MB 144 pens from different time periods and pulled many many 144 nibs for repair, I've never seen one with that dent that you see in the linked thread. The nibs are always straight when they come out of the sections. Anyway, the nibs do pull straight out, but it is very easy to damage the bottom feed fins in the process since they are quite delicate and fine in modern MB pens which increases the ink capacity of the feed. A few companies use this type of design for the feed fins where the feed fins are not a radial design but are like plates hanging off the top of the feed. I think it is a good design. If you look carefully, most all modern MB pens have a notch in the bottom of the feed that is reinforced and serves as the point where MB's tools fit and allow for safe removal of the feed and nib. Chrissy is right in that there is a special tool to pull them. I don't recall much about the feeder cases of MB 144 and 145 pens since it's usually a bad idea to remove things that don't really need to be removed since there is a risk they could get damaged. In the case of the 146 and 149, there is more reason to remove the feeder cases if the pen is being serviced, but this isn't really necessary with the 144 and 145. In my experience, it is also better to reinsert the nib and feed with one's fingers if one doesn't have the proper nib tool that MB has. This can prevent all sorts of damage from happening to the nib and feed. Many of these pens also have keyed nibs, and one has to take care to insert them in the right way or the feeder case can be damaged.

 

Nowadays, if it is not necessary to remove the nib, I've developed processes using very specific abrasive formulas and sequences that allow me to do a lot of important work on the nib when it is in place in the pen. I often use these processes when working with MB pens to avoid damaging other parts. Of course there are many times when the nib and feed must be pulled, but in some cases, I think it is better to avoid the risk.

The only times I have pulled a nib and feed was when the section broke. In one case the old model plastic section broke at the threads going into the barrel. I happened on a new style section and put the nib and feed into that new section.

 

I bought a 144 where the new section turned out to be broken. Later on I bought a blue section from Speerbob and put the nib and feed into the blue section. It looks odd in a red pen, a converted rollerball.

 

I don't think you should just pull nib and feed out unless there's a good reason, but they are your pens.

I have dismantled my 145 and the nib just pulls out with gentle persuasion and no tools required. I got this far and am waiting to see if the remaining piece is glued into the threaded connection or does actually come apart. All this to try and sort out a flow problem that may be due to something else (but hopefully not).

Gregjam how did you get on with your 145? Did it dismantle OK?
