I have an issue with my MontBlanc 146 LeGrand Solitarie, piston gets stuck at the bottom of the barrel.

[Humberto]

I bought this MontBlanc fountain pen a few weeks ago and it was all full of dried ink. I cleaned it and I think I forced the piston mechanism, as I could unscrew it and I took it apart. Now when I try to suck ink from the reservoir, the piston gets stuck at the bottom of the barrel. Any tips on how to fix this issue? Thank you very much.

It sounds like you need to lubricate the piston head. Can you post pics?

Yes, I can, which pics should I specifically send? Thank you

Maybe you accidentally broke the helix rod ? the dried ink can prevent the piston to move easily.  If you can separate the bottom cap from the pen, it is most surely broken.

Fortunately, it is reparable, the best is to send it to someone who repairs Fountain pens, ask before hand if they do that repair on Montblanc, OR send it to Montblanc, it will be a standard reparation, should cost around 100-110 € / USD

What is a helix rod?

Sorry, I am pretty new to Montblanc pens

This little plastic with a shape in helix or DNA like (coming out of the know on the picture) , make that when you turn the know, the piston goes down or up. This is usually what breaks.

I'll attach you a pic of mine and tell me if you think it is broken, because it seems like it looks the same way as yours but I am not sure
