pilot con-40 full assembly and disassembly

 So we have a con-40 here. There's ink behind the piston, and you want to remove it. a complete disassembly is in place, but how?

Here's the end result you want:

Of course, this is the other end result you want too: 

 Components:

i'm just going to define these components so that it is easier to guide later. 

the ball gate

 the 4 balls:

the piston:

the c-clip:

the metal ring:

the converter body:

the twist component:

Dis-assembly:

usually people start with dis-assembly, but since dis-assembly is an exploratory and classified as a destructive process, i rather do a detailed assembly process. Thus, please reverse the sets from the assembly to dis-assemble the converter.

of course, there is a minor insignificant reason that i did not document this process and is too lazy to do so. I will just insert foot note to take care of during dis-assembly. :p

Assembly:

you insert that piston from this direction: 

[Dis-assembly: push the piston out from the front. it is not to be extracted from the back.]

then you insert that c-clip in. note those groove inside the converter body and align the clip's groove accordingly:

[Dis-assembly:Nothing it dis-assemble here....move on...] 

then, use the twist component and push the c-clip in. make sure the c-clip goes straight to the end.
[Dis-assembly: remove the twist component, swing the piston left and right and pull a little. the c-clip will slow move up and out of the converter body.]

then, push the twist component in. you should hear a click. it means the groove has gone into the drain.
[Dis-assembly: note that the twist component is turning on the drains on the converter body. the converter body holds onto the twist component like jaws, upper and lower portion. to remove the twist component, gently bend towards the upper jaw and pull a little so as to dislocate the twist component out of the lower jaw drain, then do the same for the lower jaw. be careful as the converter body is plastic, no big movement, just gentle nudge. the bend is to be just enough to clear the drain.] 

next, put on that metal ring. just push it in and you should hear another click.
[Dis-assembly: get a grippy material, hold onto the metal ring, turn it. then pull] 

lastly, put those 4 metal balls in, and insert that ball gate.
[Dis-assembly: get a 2 legs pincher, leg in the 2 holes, turn, clamp and take out.]

Done!
