A couple of weeks ago I bought my first Kiev (a 1974 4A), and it seems to have rather rudely pushed its way to the front of a queue of a couple of dozen other cameras that were waiting patiently for their turn on the repair bench!
It has obviously suffered some sort of liquid accident and much of the mechanism is quite badly rusted. It's certain that anything less than a full strip-down would be a waste of time. With the aid of the excellent Kiev Survival Site I have removed the shutter mechanism without mishaps, and I'm now moving into areas for which I can't find any instructions.
I've marked the mesh of all the gears, let down the blind tension, and removed the blinds complete with spindles. There is noticeable friction in the spring-spindle, so I want to detach the ribbon ends (preferably with their rollers so I don't have to reglue them) and detach the opening blind so that I can attempt to give the spindle a good clean. The blind isn't a problem - if I can remove the rollers it will slide out after moving a spring clip. The question is: how do the rollers come off?
At the moment they will pull out a small distance but remain attached to their springs. They each have a little brass countersunk screw. If I take out the screw I see what looks like a steel screw-thread which remains fixed to the roller if I pull it outwards. The screw seems scarcely long enough to act as a clamp on to the screw-thread, but I can't see what other purpose it would have.
Does anyone know how to get these off? It appears that each roller, and the centre section to which the blind fixes, have their own separate springs. If I take the rollers off, will I have a problem re-attaching them in the correct position so that the spring tensions are correctly balanced? Is there a cross-sectional diagram of this spindle anywhere?
Thanks,
Steve.

I'd get this if I were you
http://www.amazon.co.uk/Zeiss-Conta...=sr_1_1?ie=UTF8&s=books&qid=1273655096&sr=8-1
it's reasonably cheap, has great diagrams and instructions, and should be useful for your Kiev too. Good luck with your repair!

Thanks, Ludoo. In fact I ordered the book yesterday, but I don't expect it for a few days. Very glad to know that you rate it as useful! Steve.

I now have the book ludoo mentioned (Zeiss Contax Repair Manual by Peter Tooke). It gives a good description of how to dismantle the spindle and I've gone most of the way there. However, on the Kiev it looks to me as though it is impossible to detach the inner ends of the springs without the near certainty of doing them permanent damage, so I am going to have to attempt to clean and polish the bearing surfaces with the springs and bearings in place, which won't be easy, but better than scrapping the camera by trying to be too clever!
I'd say the book looks generally very useful, by the way, and worth getting for anyone doing more than a minor clean-up.
