I’m trying to figure out how to repair (or get repaired) and second gen. Rotring 600 Trio Multi-Pen.
The Rotring has been in my briefcase for over a year and not used. When I took it out a few days back, I noticed that the end covering the pens+pencil had fallen off. I thought, no problem, just screw it back on. But, it doesn’t screw on all the way.
I phoned Rotring and they say there is nothing I can do. But I’m pretty handy, so maybe this is repairable?? I’ve been searching on the web and found this forum. So I thought I’d ask a question.
I had that issue, I tried carefully assembling it, but the threads just didnt want to catch. And when it did, it didnt go in all the way.
I solved it by putting a bit of super lube on the outer threads, maybe try that before attempting any expensive solutions
I don’t know this specific model but in pendulum selection multipens the threaded part of the body is generally also tasked with keeping the mechanism inside. It may have moved forward in yours, in which case you can probably feel somme mushiness when knocking (that would be the mechanism moving before the actual knock action engages). If that’s the case, you can try gently pushing the threaded part back inside.
Thank you @Wechselstift. The pencil and pen portions aren’t sticking out far enough and if I superglue it, it will be very difficult to open up again to change a pen or add some lead to the pencil.
Thank you @metal_punching_grip. I think it makes sense that the mechanism has moved. But what I don’t know how to do is take it apart. Just putting it on the table and giving it a rap seems like a recipe to destroy the mechanism.
Does anyone know where I can find an exploded view diagram or instructions for disassembly?
You misread my message, I said super lube, just a brand of lube that I had. The threads might be stuck, so unscrewing, lubing, then screwing them might stop the jam.
Now I think I’ll try the lube first and if that doesn’t work, I’ll try to disassemble. The video is pretty good although it only shows the assembly. I’ll have to be careful so I don’t break it. That would be a shame.
The structure of the one you have is definitely different to the twist-unlock one where it matters. As yours doesnt have twist-unlock, there is no reason for there to be the pins (let me call them that, only one of them is a pin) you see in the video on reddit. Both of these pins exist for the twist-unlock functionality, each grabbing in a slot of a different sleeve that allows for rotation.
So we still don’t know how exactly it is assembled, but at least for the twist-unlock, I guess the only possibile way to pull it out is by the pusher. You cant grab/clamp any other part on which you could pull. Pulling on the sleeve below the knurled part wouldnt work. However, pulling the pusher risks bending and (in this case) breaking the pin.
Yes, sorry if I wasn’t clear: as @Wechselstift said, none of the pens depicted are the same as yours. They were only intended to give an idea of what’s inside (which should be roughly similar, with the exception of the twist-release mechanism). I still think that your best bet is working from the front and trying to move the threaded part without attempting to disassemble further.
