My Zorki just started misbehaving. The shutter appears not to have cocked properly, as a seam only usually visible during winding on is now visible. The shutter won't fire, lever won't wind on any more. Got a feeling if I could just get the shutter to cock a tad more it may fire and everything will be ok again. Any suggestions?

Mike.

maybe something has gotten stuck in the gears and is blocking it from winding fully. probably needs a disassembly to find out in any case

The basic Zorki shutter mechanism is a tough so and so, but as Rick mentions is prone to getting film chips in the teeth of the bottom gear-set.

Firstly try and rotate the sprocket shaft in the direction of film travel, sometimes this allows the shutter to latch and thus be released. You can also try flushing out the bottom gear-set with Naphtha or Ronsonol. This certainly works on the old Zorki '1', however the 4 is a bit more awkward as the gearing is more difficult to expose.

It is possible to clean the gears of film chips without a major stripdown of the shutter mechanism. A stiff artist's 3/8" flat brush and naphtha will allow you to clean the gear teeth.

If you need help, Rick's site has all the information you may require.

Thank you gentlemen for the info. With the help of Rick's drawings I managed to disassemble the camera, clean the offending gears and reassemble everything afterwards. All seems ok again. Thanks again.

Glad it worked out! Life isn't always that cooperative
