help to save Zorki 4K shutter

[chris_zeel]

Thanks for the advice people!

I'll check as soon as I get home.
I don't think it's a piece of film, since it has been album two years since I last ran a film through.

The selftimer pin is a good possibility. I also noted that the curved arm (located behind the sprocket spool) was a bit wobbly.

I'll send an update as soon as I did some testing.
Many thanks again!

Okay, it's not the pin of the self-timer that is causing trouble.

The pin that comes from the shutter button just won't retract to it's position and to relax the shutter release spring.

How can I best fix this?

I already went through the CLA stickie to some extent, so I'm prepared for something.

It seems that the collar round the shutter button is not positioned upright totally. Can you grab it and pull it up by turning it clockwise or counter clockwise?

Good suggestion, but it does not seem to work.
I tried till my fingers started to hurt and I thought of getting pliers, which I didn't do.

I guess that this would be similar to what Murray suggesting by flicking the shutter button.

I guess I'll have to do a CLA, at least with the shutter button and components working of the shutter release spring.

Any tips to get underway (using the CLA sticky on the forum).

I have to dismantle the top cover and get straight over to the shutter button?

Would that be the best way to go?

Zorki 4K not always cocking shutter

Zorki 4K not always cocking shutter

When I wind on my Zorki 4K my shutter doesn't always cock, I lost an entire roll of TMax with it. I thought I'd fixed using a release cable and it was ok for a while so I thought I'd risk a roll of Acros in it, but it's now doing the same again. Again I've managed to release it and as far as I'm aware the film is ok with maybe a couple of frames have been lost. Any help would be gratefully received as the camera was a present and the bin isn't really an option.

Thank you for moving my post, there's a lot here for me to work through.

If you follow the CLA sticky, take the top cover off and dismantle the shutter release mechanism. I agree that it is not returning to "advance" mode, this is most likely caused by dried-up grease in the rods and spacers under the shutter button and release collar.

It's not difficult to get at it after removing the top cover, just read very carefully about the 4k's winder spring and be careful to do exactly as the CLA directs you.

EDIT: just noticed it's a resurrected thread!

I think the cogs are turning. I have to check when I'm at home but I think that the light metal spool is turning, but the two notches visible in this picture are just missing to touch each other:

How should does this normally work?

Just out of interest - the photograph here illustrates what is wrong......the flat spring should be engaged with shaft, under the sprockets, rather than sitting on top of it, as it is here.

That's what I meant by #16.🙄
