After adjusting the second curtain my camera stopt.
I can wind it but when I fire the shutter nothing happens. (just a click)
The mirror moves only when I press it with my hand. (without the lens)
One curtain is in the mirrors way, and stops it from moving.

What I can see is that the bar that holds the second curtain is blank.
You can see on the next photo what I mean.

Is it suposed to do this? And how can I get the curtain back in position?

Thanks in advance

Hi,

had a look at my 3M. Not sure if that is what you meant with a blank bar - but see below. The rod that runs down at the right hand side of the mirror (seen from the front) is always blank. The curtains does not spool on that one it runs behind it.

3m detail

I have modified the image you linked to - I hope that this was OK.

Between the rod and the curtain a flat piece of metal should be visible.

Shutter speed dial: IIRC the shutter speed should not be changed with the 3M (and similar Russian cameras with a dial that rotates when cocking the shutter). Don't force anything there.
Sorry can't help more for the moment.

Regards
Martin

Sorry,
wanted to say the shutter speed should never be changed when the shutter is uncocked.

Ok, the rod must be blank.
On the other side of the mirror, the curtain is winded on an other rod.
There the curtain sits loose around the rod. I mean not tight winded.
(this curtain comes against the mirror)

When I cock the shutter, and press the shutter nothing happens with the curtains. They don't wind or move anything.

(It's ok to modifie my pics)
Thanks in advance.
Stan.

Hi,

the curtain should wind tightly on the left hand side of the mirror (seen from front) The mirror should not touch the curtain. With cocked shutter there is a gap of approx. 1mm between the drum and the side of the mirror.
I have never taken that kind of shutter apart but here are some links which might be helpful:

Text is German only but good photos

Might also be useful (in English)

Here a link to Jay Javier's site - disassembly of a Fed is shown but the shutters are very similar so might be useful as well

Sorry, cannot help better than that.
