Konica C35 rangefinder adjustment and repair manual – step by step

After I’ve repaired the metering I realized that the rangefinder has problems too. The rangefinder only reacted on settings in the close range. When I kept on turning the lens barrel into the farer range (about 3 meters till infinity) the split image just stopped moving.

First I tried to adjust the rangefinder through the screw that is accessible through a little hole under the back door which is covered by a screw that has to be taken out first.

If you open tha film chaber door you find a little screw right below the viewfinder. This has to be screwed out completely to access a tiny screw that adjusts the rangefinder.

Here you can see the adjustment screw. This screw adjusts the complete range from close to far in a whole. Later I will show you which screw adjusts the relation between far and close – it is very unlikely that this has to be adjusted.

If this does not help the top cover of the camera has to be removed – don’t be afraid, it is easier than you might think. You can read this article where I described how to remove the top cover.

After you removed the top cover come back here to see how to continue.

 

Remove the three green marked screws, now the whole rangefinder assembly can be removed from the camera.

On the bottom of the rangefinder unit I removed this large headed screw because the brass arm was a bit stuck. It did not move back completely when the black lever was pushed and released afterwards. I put a tiny drop of lube and retightened the screw.

I’ve also put a tiny drop of lube under the brass lever. There is a little outtake where the lube can be placed at. In this picture you also see the adjustment screw that can be accessed through the film compartment described in the very beginning of this article. It is in the top right corner of this picture. It is also possible to adjust the rangefinder now.

But still the split image got stuck so I went on looking what could be fixed.

If you take off the black paper cover from the rangefinder unit – it is hold in place by two very tiny screws – you will find this red marked screw. Don’t touch this screw, it adjusts the relation between close and far focusing. This should normaly be no problem.
The green marked screw adjusts the vertical alignment of the rangefinder. On the Konica C35 automatic it can be accesses through the hot shoe without disassembling the top cover of the camera.
Anyway if the rangefinder is stuck like mine it may help to add a tiny drop of lube to this screw.
When I loosened this screw the vertical alignment wen’t completely off and it could not be readjuster by tightening the screw. I pushed with some force on the base besides the screw and the alignment was spot on again.
I fixed the screw with loctite.

I hope this description can help you a bit and would be very happy about a comment.
