Kiev shutter problem

[Peter_Jones]

If this pic works, this is what happens to my Kiev shutter at all speeds below 1/500.

Basically the second curtain does not "land" parallel to the first 🙁 Any suggestions would be appreciated (other than use fast film and only 1/500 and 1/1250) ?

Looks like one ribbon might have broken?

Concur with previous posters- shutter ribbon replacement is needed.

Seems to be plenty of info on the interweb about changing ribbons - That'll keep me occupied 🙂

Peering inside, the ribbon seems to be in situ. I cannot however remove the casing, the top right screw fouls the top of the body and will not come free. Time for a subtle modification 🙂 I will definitely get the correct Arsenal ribbon, life's too short to do botch jobs. Might as well attempt a CLA while I'm in there.


Thanks everyone for the very quick answers 😀

Edited to say ; the ribbon appears to be OK, but the curtain is catching on something, fingers crossed this could be a (relatively) easy fix ?

The top plate needs to comes off before the shutter module, you will see why when you remove the top plate. The screw will just clear then.

The interference you have is probably the synch switch, it seems to be getting above the 1st blind 'wing', if you have a dentist mirror you might be able to confirm, otherwise it is strip out the shutter module.

The synch switch can get out of position but I've not seen it give this symptom so it may be film or other foreign object and you might be able to remove film (without a strip) with tweasers and care, though the shutter run path slit.

Lock the shutter securely if you try tweasers in situ & Good luck

P.S. If you have to bend the shutter 'wing' take care it will snap real easily

Thanks, Noel. I dislodged a "bit", definitely a foreign object (not a Kiev part), and fired the shutter several times at each setting , fast to slow, all seemed OK. Then I fired the shutter loads of times at each of the speeds. Problem has not shown itself, and the shutter speeds seem closer to what they should sound like on the slower settings (they were much slower before)
Don't know if I've warmed up some lubricant (my fingers are certainly warm after all that winding - approx 150-200 shots) but will leave it to cool and keep testing.


Fingers crossed AND touching wood 🙂

Good news Peter - certainly looked like a broken ribbon in that pic! You should be able to remove the film gate by lifting that top RH screw up as far as it will go and then sliding the casting down a bit.

Did you remove an object if not you still have a large film shard, a broken off synch switch actuator (the wing in my previous post), or a detached synch switch, floating loose, any of these cas cause more damage or jam the camera.

If the actuator or the switch is damaged you need not repair but you have to remove any loose bits.

If you do decide to leave the camera as is when you shoot vertical keep the rangefinder window high and the viewfinder low...

It takes me a weekend to strip and reassemble the camera, sorry

I'll have a nosey in there anyway, might do a rudimentary CLA (what I can get to without too much difficulty). Been firing off shots today at random speeds in various positions (the camera not me) and so far so good.

Thanks, everyone, for your advice.
