Cleaning A Mont Blanc 145 Vintage 1982

[Erik Dalton]

It's not something I've ever done myself, as I don't have any 144 pens. Obviously the push on pull off cap uses some sort of an internal clutch in order to stay on. It's possible that clutch might use the gold plated band as the pressure point for the clutch, but it won't use the nib itself..

Yes, they have a plastic inner cap. It’s not uncommon for them to split, making for a loose cap to barrel fit. The snow cap unscrews. The snow cap has a stud on it that extends down into top of the inner cap which has a threaded brass top to it. Once you get the snow cap off, the inner cap comes right out.

Roller balls also have a similar inner cap, look similar, but it is not interchangeable with the FP cap. Use caution buying parts.

Heres what it looks like broken down.

You can actually break it down further. The grip unit consists of 6 or 7 parts. I'm able to do this by holding the metal threads and firmly unscrewing the golden ring on the top. Can post a picture later today.

here is what it looks like. I was lazy and didn't take the feed and nib out


Once you take the nib and feed out you can remove the ring (I have a spare grip section without the feed and nib)

Use caution, go slowly. The components in the section can get brittle and are easy to damage in older pens.

Great info and thanks for the pics! The instructions in the pic I posted suggested using "heat" to help get the nib collar safely out. Is that part of your method as well?

Also, I assume the nib and feed are friction fit?

Very good point. My pen is fairly new (I think 90s) but even then I was extremely careful. I was wearing latex gloves which gave me a slightly better grip against the plastic/metal components.

Yes, they are friction fit.

Also, I assume the nib and feed are friction fit?

 

 

I had this pen soaked in warm water the first time I did this to clear a clog. So may that was enough. I was afraid of over tightening these when I put it together so it does NOT require a lot of strength to take apart now. Had inked it and it did not appear to leak, so maybe what I did works!

Thanks for all the info folks...this is very helpful!

 

Going back to the subject of cleaning and using a pen flush...are there any pens you should not ​use pen flush in? I read somewhere on Richard Binder's site the ammonia in some flushes can cause damage to certain pens. I just purchased a vintage 144G and want to ensure it's safe to use before giving it a proper cleaning.
