Disassembly Of A Mb "4" Safety Filler

[farmdogfan]

I am attempting to change the nib on my Mb "4" safety filler, but i can´t unscrew the mechanism, i tried with some heat but it does´nt move, any tips or tricks will be appreciated.

From memory and it's a vague one, the helical rod which holds the nib is pinned to the filler knob, once this is removed the rod comes out allowing access to the nib. I serviced one going back a few years ago but can't be sure of the exact procedure. Look for the pin first as this may give you better direction

Thank you Slippery, yes there is a pin, but it is probably corroded or something because it does´nt move, i will try again though.

Well, the pin came out but the filler knob does´nt move.

I wish I could be of more help but it was some time back that I did the service/repair on my safety filler which I no longer have.

I have decided to leave it be as it is, but thanks for your effort, i appreciate it.

I tried again today, and this time i was lucky, i managed to take it apart and change the nib ( the old one has a tiny crack, that i will get fixed by a goldsmith ) i was going to change the cork, but it looked good, so no need to do that ( it was´nt leaking either).

Nice job. Well done!

[farmdogfan]

Thanks, now i can use it again.

 

 

BTW, it´s not a crack on the barrel in the first pic, it´s just a small string of paper towel.

Glad to see you've had success. I very much like the design behind safety pens
