Montblanc 146, How To Disassemble & Maintain The Piston.

[FPjunkie]

This is an experiment, showing how to disassemble a late 80s Montblanc 146 piston parts using a simple paper clip

Please note that MB fountain pens are expensive and I do not want anybody to damage his/her fountain pen by performing this experiment,

You may need to preheat the upper section of your FP with a hair dryer (set on moderate heat) before using this method, to protect the FP from possible scratches you can also use paint tape to cover either the brass section, barrel or the cap.

So here is how to open the piston section and maintain your MB 146 FP, your inputs are absolutely welcome,

Thank you

Awesome - thanks! I wonder if a similar technique could be used to remove the feeder and nib assembly.

Thanks for the directions with photos.

 

After viewing a video on the internet where they use a special made tool to disassemble a MB 149 I´ve thought that maybe a paper clip should do the same but haven´t tried it.

Thanks so much for the nice comments.

I believe the same method can be used for MB 149 , but I do not recommend it for opening the nib side though, to me it is too risky and can damage the nib feed, specially for vintage MBs.

You all are so brave I would never do it myself!

I would add that the paperclip is less likely to come out of the holes if you close the filler knob onto it before attempting to loosen, or tighten, the brass part. The 'prongs' should be the same length, neither too long nor too short, and the best fit you can make them. Use a fine file to shape them and remove any burrs before starting. If the paperclip buckles on one side when applying force then either choose a thicker paperclip or use a safety pin, which is made from harder steel.

Thanks for posting this very informative article. Your pictures do answer some of the mysteries of the inner workings and setting up the piston stroke following a strip down.

 

On a personal note I only use the tool produced by Francis as I have had a couple of 146/149s were the piston mech was very tight to remove and I could not see the paper clip method working due to the lack of strength.

You have to be comfortable doing it, if you are not, please don't even touch your precious MB, there is always a profassional who can do it for you worry free.

Thanks for the posting,

Thanks so much for the comment,

It definitely help to have the same length prongs, as you can see in pictures the brass section has 2 square or rectangular holes which it would be great if you can use a bigger clip and file the tip of the clip to square shape, it also gives you better torque ( the longer the length the better!), but as Ientioned the clip has to somehow be fitted into the wholes.

Thank you for your kind attention to my posting and I am so glad that you found the pictures usefull,

As a rule of thumb (and as you know better thatn I do),for sure utilizing the proper tool or profassional services are superseding my experiment, also they are highly recommend , I'm not sure how much you have paid for the tool but probably it worth every penny spent , it definetly makes the whole process of maintenance so easy and hassle free.

In my case, I would rather to try other options, I had to chalange this MB's speciallty tool taboo , it was bogging me for a long time and this article is the result of thinking about that, so I decided to share it with our great comminity.

Cheers,

Thank you very much for the information.

It is very useful for all fountain pen lovers. Do the same in the official technical service of MB has a savagery price.

Best regards
