This incidence really upset me and my other half advised me to send the pen to MB boutique shop for servicing in Germany, which may cost me between £40 to £80 and it will take 3 weeks to get my pen back. Since I have about 9 MB pens in my collection, it would be more cost effective if I could service by myself in the long run. I put Temporary Pace Maker Wire to patient's heart at work when their heart beat is not fast enough to maintain their Blood Pressure and Circulation. I thrive on challenges!!. I also enjoy DIY for my hobby such as Radio Control Model Helicopters, which needs high maintenance. Each helicopter costs around £2000 to £4000 and if it is not well maintained, they will crash, like a full size counterparts...( Please do not misinterpret that I am boasting about me, I am a humble servant of God and Most grateful that he gave me live saving skills and I do not do any private practice. Money is not the end of the world and the quality of life is more important to me and my family. )
After reading and studying MB Piston Topic which was posted by Niksch which was pinned at the start of the Forum and Harri's Article on MB146 and 149, I ordered MB Nib and Piston Filler Removal Tools from "Fountainable" from this FTP Network member. Thank you very much Francis to produce such a wonderful precision instruments and without your innovation, we are not going anywhere except to Montblanc Service department.
I have attached some pictures and it was a very enjoying experience to service by myself. Dried ink inside the barrel and less elasticated Piston can cause ink leak backward toward the Filler cone.
The Tools come with an instruction from Fountainable. I am also very grateful to Niksch and Hari for their posts on this Forum. Pen is not leaking anymore and write really well and ink flow is fantastic. I do not need to remove the Nib and Feeder on this occasion as the problem is at the back end. Not at the front!
While the piston was out, I have cleaned the Nib and Barrel with Ultrasonic Cleaner and therefore I did not need to remove the Nib/Feeder section on this occasion. I also use DE-ionized water to clean the pen rather than tap water because of Calcium Contents and small particles from the water pipes. I also soaked the Brass component in Ammonia solution to experiment whether ammonia can dissolve any dried ink residue and the answer was Ammonia could not remove any dried ink and this experiment made me believe that what MB said was right and not to use any soap and chemical detergent for their pens. They could dry out the Elastomer piston ring which is self lubricating material.
This statement may upset some forum members who advocate soap and chemical to clean their pens, nevertheless, nothing stop you from using these agent if your experience is excellent and every experiment has some draw back perhaps I did not soak long enough to remove the inked stain on the brass component!
If I upset anyone, please accept my apology. But healthy debate is good for the interest of maintain good MB pens, the pens we admire so much. In my profession, everything what we do is evidence based and it is open to scrutiny.
So , the choice is yours!!! Best wishes. Htin
