Any hints on how to do the repair? Where do I stick that screwdriver?
That body has probably not been used at all
With the screwdriver I removed the bayonet (5 screws). Here are some hints;
-Behind the bayonet (and the black plastic ring), you'll see two flat springs. One on the top, for the exposure correction clicks. And one bottom right, for locking the film speed.
Take a good look at how the springs are positioned (or make a photograph), then it will be easy to put them back in the end. They are not small so no worry that you might lose them.
-in my case, the metal behind the spring on the top was a bit corroded/ dirty, so I cleaned it with a bit of alcohol. If it is not clean, obviously the correction ring will not turn smooth. I think it is ok to lubricate this part with a tiny drop too, but I didn't do that.
-I also removed the asa dial to see which part on the camera is actually moved when it is turned; it is a lever that is located on the right outer side of the
lens opening. This lever is what links the asa dial to the light meter. If you push that lever up and down, on the inside of the lens opening you can see that the lever moves
yet another ring. I thought this ring had a bit too much friction when moved, so I put a tiny bit of WD40 (with cotton stick) onto that ring -where it touches the non moving surrounding- to reduce the friction
and put everything back together.
When putting things back together;
-on the inside of the asa dial there is a empty space that holds the lever; make sure the lever is indeed fitted in when placing back the dial. If it is not in, the ring won't move at all but gets stuck.
-Take care the flat springs don't get trapped in between the black ring and asa dial, but stay on their place. If a spring partly gets in between no harm will be done but the bayonet simply won't fit tight. When placing back the black plastic ring; on the backside of it there is a little empty space to contain/ hold the 'film speed' spring in place. Again, if the position of the ring is not right it all simply doesn't fit well.
-There is actually a third really big circular spring (brass coloured) that attaches to the back of the bayonet, to 'hold' the lens. Its position is very obvious so I didn't give it attention, but when attaching the bayonet make sure it is positioned ok.
So except for the screwdriver you need some common sense, a little patience, alcohol, a cottonstick and perhaps a drop of wd40 or other lubricant. After assembling I moved the iso dial up and down a few times (8-6400 asa) and everything is working smooth again.
