Piston Removal On Mb 344

March 16, 2012

Have also made this post in the repair forum, but maybe someone here can help me in the right direction.

I think it's a 344, but there is no inscription on the pen.

Also it seems a cap from another mb (think 334) instead of an 344 model.

The palladium 4 1/2 nib it also not the correct one on the pen i guess.

Any info on correct model would be welcome.

Second part is about the removal of the piston as posted in the repair section.

Have acquired an 344 with an 4/12 palladium nib today!!!

Will need to make me a tool to remove the niib this weekend and would also like to overhaul the piston/cork this weekend.

Is there anybody who knows to remove the piston assembly from the body?

I know how to do it for an 334/234 but not for this model. Here there is no blind cap, but the knob is directly on the pen itself.

Is it possible that this acts the same way a lamy 99/2000 does? Our do i need to "screw out the threaded part out of the barrel?

any boughts would be welkom to get my new pen going.

Regards,

Adam

Got the pen cleaned and assembled already!!

The piston just got out by warming gently and turning the "ring" on the barrel CCW.

Lubed the system up and put it back in.

Need to say the system is nicely build with some brass components, real quality stuff. Another nice detail is that it isn't a cork anymore, but that it has a rubber ring to seal the system.

This is the tool i've made up to remove the nib on the pen, not a high quality stuff like fountainbel's impressive tools, but a usable diy grade and simple tool made out some steel tubing lying around.

Only thing i still would like to know is with model of pen this could be.

Cheers,

Adam
