Sailor Realo Disassembly & Maintenance

[VillersCotterets]

[...] Why do people still think pistons are made from brass and clearly not stainless steel [?]

Because Pelikan advertise their high end Souverän M800 and M1000 as piston fillers made out of brass.

im not sure if brass is suitable with ink... seriously why do people still think pistons are made from brass and clearly not stainless steel.... especially in the VAC 700 and custom 823

 

Rods in both may be SS but threads/ mechanisms are brass because it is much more expensive to machine SS.

Ink does not contact the metallic parts of the piston mechanism, on well designed pens like Pelikan, Montblanc, Pilot etc. On the 823, the filling is plunger type and the metallic shaft is in continuous contact with ink and has to be of a non reactive material like SS316/317.

How important is it to be able to re-grease or re-lubricate the piston? I'd rather not mess with it if I don't have to. I haven't gotten my 823 yet but will within a few months (2 Falcons and an CH912 interrupted my plans to get an 823). I don't mind a little ink left behind in the pen and wouldn't feel the need to disassemble the pen just to get the last bits out, but, I am concerned that the pen would need some piston maintenence let's say some 5 years down the road. Couldn't I just send it back to Pilot and let the competent pen meisters there do it?

well this is a more sound logic... seriously... its like saying a full metal piston filler pen (no bindes but bare naked metal touching the ink most of the time)... (I havent seen one but if I see one that doesnt corrode call me fancy) Edited May 27, 2015 by Algester

Only very rarely do I have to pull out the nib/feed if the feed is really clogged or the piston needs lubrication. But it really isn't that difficult with modern Japanese pens.

I also think that part of the reason that the threads are made of brass is that two brass parts can slide against each other.

 

"Metals such as brass are often chosen for bearings, bushings, and other sliding applications because of their resistance to galling, as well as other forms of mechanical abrasion."

My questions is how to disassemble the Realo, not if you, personally, prefer to pay someone to do it for you.
