TWSBI Go Lubrication

[Dip n Scratch]

I definitely need to lubricate the piston of my Go after the present fill of ink is used. The piston is becoming a little stiff in the bore that the spring pressure alone will not return it to the top.

Is the pen capable of being dismantled and lubricated? I note they did not supply any toll to dismantle the pen.

Jetpens has a page on disassembly of Twsbi GO.  Quite detailed.  In it it shows how to remove the plunger, which, you can then lubricate it.

I binned a Go recently without realising the plunger knob had an opposite thread.

Fixed my other Go inside 3 minutes. The piston was bone-dry.

an efficient way to lubricate the piston of the GO. It should not be done if there is no need, the plastic can  be brittle and break with no apparent reason.
