Unfortunately this part was porous and broke during assembly ...

Very nice pictures. Interesting to note the STOD mark on the end.

 

BTW, The part that broke: the feeder case, was available on ebay the last time I checked. That is a fragile part and nowadays I rarely remove the feeder case unless the pen is leaking from that joint. I prefer to knock out the nib and feed with the punch inserted directly through the end of the barrel. YMMV.

 

Best

Hari

 

PS: Generally, the vintage 146s refer to the celluloid models from the 50th and earlier. Those had the wonderful two stage telescoping piston mechanism and cork seals.

This pen had problems writing and several leaks. The channel for the ink was clogged with dirt.

 

This is when tightening that the part broke.

 

Today I look for this part but I have no access to the corner sale on the forum. I do not know why...

 

I contacted Fountainbel and Maxpens but they have not the part

Xavier,

 

The part is available on ebay:

Good luck!

[ocedare]

I ordered it but I'm not sure compatibility of the part. The slots are not 180 degrees, it is a recently part and I have not the tool.

 

It will serve for another 146 I have.

[hari317]

Xavier, that really does not matter. I would just tighten the feeder case back without the tool. Once the part arrives, check fitment of nib and feed in the case and the case to the barrel. Remove the nib and feed. Apply sealant to the feeder case threads and screw the feeder case into the barrel: finger tight. once it is set, insert the nib and feed.

That's what I thought at the reception to the part, thanks

 

But if I can find the original part, it will be even better.

very nice 146 enjoy your pen

Ocedare and Hari, thank you very much for your posts on this and on the disassembly of a MB 149. Compulsory reading for all MB lovers. Love it. Thank you.

 

Pavoni.

Thank you :embarrassed_smile:

[daenghafez]

Thank you for sharing the 'exploded' photos of the 146. It must be an ardent tasks to dismantle it all.

[ocedare]

Mix an old body and a new case feeder, it is not possible.

 

Sorry my English is not good enough to explain so here are some pics:

We must replace the body and the case feeder together. At a minimum ...

Or find an older case feeder.

 

I have nothing to check but it is possible that the notches on the body change on the new body. If so, we must also replace the tube just above the case feeder (in the last pics).

Quite an interesting issue on hand.

I maybe overlooking potential problem with my suggestion below so kindly call it out.

 

If you ground off ~3mm from the threaded end of the feeder case (FC) it maybe possible to screw it in all the way. The biggest assumption being the outer diameter of the middle portion of FC is less than the inner diameter of the barrel tube. If not then you may try grinding it down to make it fit.

Now this is a very crude solution but something to make it functional again.

Thank you for sharing with us. Very exciting and educative topic Cheers.! . Htin

[hari317]

The newer feeder case seems to have a slightly bigger OD as well, can you measure that? very interesting. No wonder MB simply fits the old nib into a new body on pens sent in for service.

@xavier (or anyone who knows):

 

How did you disassemble the feed and nib out of the feed holder (or what ist the name of this part?)? And why did you break your feed holder – in other words: how do I avoid cracking it?

 

I tried it a lot to disassemble this part by soaking it two days and give it several hot water showers. But the nib and the feed stuck in the feed holder without moving.

Xavier may reply, but this thread is over 3 years old, so I'll step in, in the interim.

First of all, thanks to Xavier. Great post. Glad to see it resurrected

 

The nib and feed have to be knocked out of the feed sleeve. (aka feeder case, feed holder etc etc)

It's a friction fit.

 

As Hari points out, this can be done from the far end of the pen (once the piston is removed).

I'd recommend his suggestion. The feed sleeve seems to be the weakest part of the 146. I have broken two, over the years. Maybe it's the materials used, or maybe the it's fact that they spend much of their life soaked in ink - but, if you do decide to remove it (tool required), take great care.

 

Good luck

Thanks for the instruction!

 

After all, I'd better keep my hand off this! I had a problem with the ink flow and solved it by bending the nib a bit. So there is no nead for this anymore.
