Mb24 Piston Repair

[mitto]

Is the piston on this (grey) MB24 repairable. The piston knob has detached from the filling assembly and the piston is stuck/frozen, I asume because of the dried ink.

The piston knob screws back to the barrel.

Yes, it can be repaired, and maybe you will not need any replacement piece. You need to disassemble that piston. It is a pressure fit piston. You need to:

 

1- Put the pen in water for at least 24h

2- unscrew the section and make sure you clean all ink remains from inside the barrel as much as you can

3- give gentle heat to the lower part of the barrel where the piston is and with a dowel push from inside to take the piston out.

4- make pictures of the seal and parts that are still inside the barrel and show us to see what you need to do next.

 

It is not a hard repair, but requires patience and do not force too much as those plastics break very easily.

 

I have replacement parts for the piston parts and seal, but I do not have a barrel to replace you if you break that, so be careful with it

 

Hope it helps. Any questions, feel free to post them here!

I agree with Piscov.
