Need Help: My Kiev Knob Has Shifted Position.

[ruben]

I have been working with my Kiev 4AM, and before closing the top casting I made a series of speeds checkings, involving of course speed change.

I have made something wrong, which I am not aware of, as a result of which all the speeds are OK, but the real point signaling the speeds on the winding knob has changed from the mark, to some 1cm closer to the viewfinder. In other words, all speeds continue to work, but the camera is asking me to change the original speeds arrow upwards.

How do I correct this ?

Cheers,

This Kiev 4am is dancing me the sadist tango of my life.

The easy way is tippex and nail varnish.

The shutter when it fires resets itself by winding all the gears back to their origional settings, only the winder knob does not spin back. You should not have dismantled the cogs...

And the hard way ?

b) what are the "cogs" (English problem. According to babelfish "cog" = teeth. But it is the Kiev who is dismantling my tooth, not vice-versa)

Babel fish is correct, a gear wheel has teeth rather than a rubber tyre, i.e. cogs.

I cannot do the change you need to do from memory, nor have I stripped a 4am.

The speed knob alters the escapment controls and the shutter gap width, you will have to look at the mechanism as you turn the speed selector. You will then have to adjust the positions of the cogs to get the speed dial correct. If the camera is worn the speed may be dependent on setting before or after winding.

It is not obvious how the cams control the escapments. I have spent hours looking at an intact camera... It had a frozen escapment part, but I could not tell which part was faulty, so I lubed each in turn, and nudged gently with a dentist pick...

I normally clean the shutter mechanism in situ to avoid the pain of resetting everything. Kiev maintenance is so easy because you dont need to strip the shutter module even to replace ribbons.

Note unlike Dave who tends to enjoy your problems I'm real sorry.

Could it be that one "cog-wheel" had slipped a few teeth relative to another wheel? The movement of the shutter speed knob is transfered by so many "cog-wheels" to the upper curtian drum, that it might had happened... or am I completely wrong? not sure...

The knob continues to shift. This may be good or bad news. I am prong to think I left something unadjusted in the process of re-assembling. So I will have to open again and inspect.

if I succeed i will buy myself from Alex one of those medals to stick on the coat. If I fail i'll send myself into my fridge.

Did you mark it with nail varnish or is it shifting a lot?

Does the shutter do all the speeds?

BTW: one broken sprocket (cog) on a wheel could cause this...

PS: I hope you have large enough fridge... 🙄

... or a chest broad enough for that medal.

Hi Folks,

Look, I propose that we wait until this weekend, since I have still not re-opened the camera due to lack of time. Formerly I have felt quite disillusioned, since I have been working in this camera a lot, and have achieved a great rangefinding.

I think all is due to not having correctly fixed some scres regulating the overall height of the top casting. Nothing has been broken, something is not in proper position or adjustment.

All the speeds continue working but I will stop winding and firing since from time to time the knob continues shifting.

So let's wait and I will see. Since it is not a classical jam it will be rather hard for you to advice until I reopen the camera and find something clear to deal about and then I will come back.

Cheers,
Ruben

The funny thing is that I have some good seven Kievs, that since I became aware of the tecnicalities - all need some or other fix. :bang:

Mystery unveiled


After hour and half of looking at the gears immediately below the knob, and telling myself "it is impossible", I learned that nothing is impossible via deception:

The only shifting part of the knob was the plastic upper part with the speed marks, that went unglued. Due to the accuracy of its fit to the chrome basis it doesn't fall, I had to use a needle to push it up.

Now you vote: the medal or the fridge.

Cheers,
Ruben

Ruben--
It's the results that count. Get the medal.
