Pelikan M400, Sticking Plunger? Disassemble?

[pe2dave]

How (easy) does the M400 disassemble please?

the filler is sticking quite badly and needs a touch of silicon grease to ease it.

You unscrew the nib and use a toothpick to apply the grease from the nib end.

Depending on how old the pen is, it may be a good idea to soak the whole pen in water overnight to get rid of any ink on the top of the piston.

Immerse the pen in water and empty and fill it under water. You will be surprised at how much ink comes out the piston end.

Once cleaned, get the grease as far up the barrel that you can and work the piston up and down.

Flush the pen with warm water afterwards to get rid of any excess silicon.

Couple of years old.

A have an ultrasonic cleaner which will do the cleaning.

Lousy design that it can't be cleaned / disassembled. At least I won't try now, thanks.

Most Pelikans require little maintenance, so other than taking the nib out for cleaning, they aren't high maintenance.

If the nib doesn't unscrew easily, leave it all to soak to get rid of the dried ink.

Every now and then work the piston and change the water a few times.

The ultrasonic cleaner helps loosen the old ink, but it still takes time to get rid of old dried up ink.

While you're at it, put the cap in as well.

The older 120/140 models use the same kind of piston and very seldom have a problem with the piston.
