Diy Self Service For Ink Leaking 1995 Mb 146 .

To take a line from a song " and the more I find out the less I know " the silicone grease subject is a large one.

 

I have been told that 100% pure food grade (?) silicone grease is the most safe to use in the lubrication world.

 

I have located a seller and will pass on details if required.

 

Regards

Also my I quickly add that

 

The MB barrel is I believe made from a variant of PMMA and it is quite right that MB does not recommend the use of commercial cleaning products for the pen, as many contain petroleum products and they damage the material.

 

Hello, I think a soapy water and Diluted Ammonia 10% with water is OK to clean the Nib and Feeder. These detergent will remove any residual polish or grease on the nib as every nib is hand made polished and installed by hands.

 

These detergent will remove any grease at the lip of the piston seal and the piston will become dry if you flush the pen with these detergent. I would prefer just soak the nib and feeder in the soapy warm water for several hours and run the nib/feeder unit under warm water to get rid off the detergent. I would not want my pen to fill up with these detergent, unless the nib and feeder unit is removed from the housing and treat with these detergent separately away from the piston.

 

If the pen is slippery due to hand held polish in the nib and feeder, then certainly these detergent will remove these residual polish and the writing quality of the pen will tremendously improve.

 

That is my opinion..

You can get 100% silicon grease from any diving shop, and you can get them quite easily on ebay. Just search 100% pure silicon grease, diving, you should find a seller in UK. I bought mine this way.

 

The petroleum based lubricants will over time make most other petroleum derived thermal plastics (PMMA is one of them) become brittle and discolour. This process only becomes apparent after exposure of the material to the lubricant in quite long period of time. However even with a little lubricant applied, the lubricant do stay on and diffuse onto other parts for a long time to come, and won't go away easily. So I would recommend you to clean the parts in soapy water or diluted ammonia solution again, and make sure all traces of the petroleum lubricant is washed away (you can use a large cotton swab to gently rub the inside of the barrel, make sure to do it gently and not creating scratches). And afterwards apply a tiny amount of silicon grease to the piston seal and work it up and down a bit in the barrel. Note that you should really be applying a tiny amount, (sesame sized lump perhaps), because although the silicon grease is inert, too much can cause a build-up near the section end as the piston pushes the excess grease downward during each filling. If some grease gets into the feed area and blocks one of the channels (meaning pen starting to malfunction), then it will be a pain to remove. The grease is insoluble to anything that won't also dissolve the pen, and the only way you can get it out would be physical (high risk of damaging the delicate feed channel) or using high pressure water (to force it out). So only apply the minimum required for a smooth operation, nothing more. One application of the grease lasts a very long time.

 

Yes, soapy water with diluted ammonia is okay for the nib and feed, and the barrel, as long as you rinse it with clean water after the cleaning.

 

PS: If you decided to polish the tarnished brass, remember that the brass polish must be throughly removed before reassembly. Also note that the "disc" part which will remain visible after the piston retracted may be gold plated, so DON'T polish that part. As you said there is no need to seal the piston housing with grease (though a little may help for ease of future maintenance, prevents the screws to cease up due to possible brass corrosion etc (a light coat of grease also prevents corrosion)). In fact the piston assembly at the back is designed not to be air-tight, otherwise you won't be able to operate the piston.

 

In practice a well cared for and regularly used MB rarely needs to be serviced this way (taking apart etc). The important word is pen hygiene: never let ink dry up inside (fill regularly, never leave small amounts of ink in the chamber for few days etc, and empty/flush the pen if not going to be used for anything longer than a week), flush clean every a couple of fills (more frequent if using highly saturated inks). And basically this is all it requires for the pen to function flawlessly for many decades without any other extra servicing.

Thank you for your good advice. Francis who supplies the MB tools himself is an experience fountain pen restorer and he uses Vaseline for all his pens and I followed his advice and my pen is working well. No ink leak and no skipping and ink flow is so smooth.

 

I also agree with you that no ink should be left more than a week and need regular flushing and the pen will last many years without any problem. No need to dismantle the pen. Thank you. Best wishes. Htin

      I have the Sailor Naginata and some fancy blade nibs coming after 2022 by a number of new workshop from China.  With all my respect, IMHO, they are all (bleep) in doing chinese characters.  Go use a bush, or at least a bush pen.

      It is the reason why I'm so keen on the idea of a personal library — of pens, nibs, inks, paper products, etc. — and spent so much money, as well as time and effort, to “build” it for myself (because I can't simply remember everything, especially as I'm getting older fast) and my wife, so that we can “know”; and, instead of just disposing of what displeased us, or even just not good enough to be “given the time of day” against competition from >500 other pens and >500 other inks for our at

      Agreed.  And I think it’s good to be aware of this early on and think about at the point of buying rather than rationalizing a purchase..
    • A Smug Dill
      Alas, one cannot know “good” without some idea of “bad” against which to contrast; and, as one of my former bosses (back when I was in my twenties) used to say, “on the scale of good to bad…”, it's a spectrum, not a dichotomy. Whereas subjectively acceptable (or tolerable) and unacceptable may well be a dichotomy to someone, and finding whether the threshold or cusp between them lies takes experiencing many degrees of less-than-ideal, especially if the decision is somehow influenced by factors o

      I got my first real fountain pen on my 60th birthday and many hundreds of pens later I’ve often thought of what I should’ve known in the beginning. I have many pens, the majority of which have some objectionable feature. If they are too delicate, or can’t be posted, or they are too precious to face losing , still they are users, but only in very limited environments..  I have a big disliking for pens that have the cap jump into the air and fly off. I object to Pens that dry out, or leave blobs o
