Pelikan Piston Knob Not Sitting Flush With Barrel



Keyless Works

Recommended Posts

Keyless Works

I have a Pelikan M600 (M400 size) and the pen functions just fine however the piston knob does not sit flush with barrel. I received the pen this way and I noticed that the piston was quite stiff and by lubricating the piston it now moves smoothly.

 

Perhaps when the piston was stiff the mechanism backed itself off of the barrel.

 

I am uncertain what I would need to do to get the piston knob flush with the barrel.

 

Please let me know if you have any tips or suggestions before I send it off to a professional. Also if you have recommendations for someone who could do this job quickly and affordably that would be appreciated.

likely a simple fix with the right tool, which would screw in the piston mechanism (i know that MB has tools that do that for the 148/9).

 

see the following video of someone disassembling the M1000-you'll see the tool....

 

 

hopefully professor propas will chime in......

Contrary to the modern Pel 800 and 1000 fountain pens, the Pel 600 piston assembly does not screw in the barrel.

Instead its fixed using a sort of snap-fit feature, using thin axial and radial ridges on the piston housing which grip/snap behind mating ridges in the back barrel entry.

Drawback is that these ridges easily deform -and even shear-off ! - after diss-assemling the piston unit a few times.

Once this occurred the piston unit easily pops partly out when the piston backs-up at the end of its down stroke.

You can restore its original position after screwing the piston fully backwards, holding the barrel firmly in one hand and then knock firmly with the palm of your other hand on the filling knob.

Be aware that the piston may easily pop out again when turning the piston completely down.

When the problem reoccurs you could decide to secure the filler unit with shellack in the barrel, or install a new piston housing.

Contrary to the screw in piston units of the Pelikan 800/1000, I would strongly recommend not to disassemble the piston units of the other Pelikan pens.

The snap fit fixation - being rather fragile - is surely not designed to do so.

Francis you are a genius! That worked perfectly! Thank you!

You're welcome.

Simple but one has to be aware of the piston unit fixation method.

Glad i could help you out !

      Not sure if this has been suggested already but would a setting for localized regions or chapters in FPN be helpful? I don't know if there is a way to find local FPN members who would be nearby. I don't know if we want to be discoverable but a setting to know how many members are in 25, 50, or a 100 miles of each other might be helpful. We can create a regions specific network like Craigslist where people could use that to connect with nearby members, conduct in person sales, arrange FPN meetups

      Hi again all, I forgot to tell y'all that I made the post about Sweden ink PIF. Most have probably found it long ago, but here's a link, anyway:

      I read your blog post and all the replies with much interest. I'm a FP user in Australia. Been part of this forum for years but rarely post. I did come across your ink sharing thread and considered participation. For me it's not lack of interest but lack of time to play around with FP and inks. I'd feel bad to put my hand up for the box and just have it sit until gosh knows when...   I also think that the FP community in Australia is smaller, and I wonder how many in the community are

      Even so, you'd end up with a fragmented list, and it becomes an O(N²) process for each prospective requestor to check what is available: effectively recreate the list of currently active servers (without any reliable up-to-date info upfront about the inks and number of samples on offer in the thread) from the sequential list of posts, which may be spread over two or even more pages, and then query each server independently to check what is currently on offer.   It comes down to not hav

      If one wanted to do this, one could just use the "About Me" field which appears to be unlimited in size.  And if a bunch of people wanted to cooperate, the Member Title field (or signature) could be used to this end - "Ink Giver" (or some such) could be used by those with inks to give...  No software edits required.
