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 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.

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.

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

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.
