My S2’s problem is the “2” seems to tight and can’t restore to proper position.

Do you have any suggestion for fixing this part?
I don't think you would need to adjust 1 or 2 in the photo. Instead, I suggest moving the actual slow speed governor a little backwards/forwards/left/right.

Thanks loads Jonmanjiro!!!

I read this thread with interest a few weeks back but really did not think this would work... I had a very beat up S2 that I was just about to put up for sale for spares with this exact problem (and a few others....!) I really didn't think I would be able to get those slow speeds going again without removing the front cover (which I can't easily as a previous owner has messed up that bottom left screw on the front panel) to get at that slow speed governor..but I followed this exact method and the slow speeds are now running fine!! Having fixed a couple of old Leica's I was convinced I would need to get into the camera more to fix the this issue!

So, slow speeds are fixed, the sticky wind on has been fixed too (with a bit of lighter fuel) and the stiff helical is improving also (with a bit of lighter fuel)....I now 'almost' have a camera I can try out! The one thing that is missing is the 'catch' on the helical to lock the lens...has anyone ever had a go at making one of these before?!

I've heard that the "catch" of a Kiev does fit.

I normally use ethyl alcohol, but many people seem to use lighter fluid.

Just picked up a Nikon S2 that is in beautiful cosmetic condition with a very nice 50mm f2 lens. But there's a shutter issue.

The left side of the final image gets properly exposed, but the right side is way dark. Seems the shutter timing is off. Does that sound like a lubrication issue (have no idea when the camera was last used), or a more complex (have to take the whole shutter mechanism apart) issue?

Thanks for any and all input.

Best,
-Tim

No, this is no lubrication issue, but this is shutter tapering. One of the curtains does not have the correct spring tension. A repair is best left to a competent repairman.
In any case: do not put oil in your camera, never.

I think mine's had this for a while, I just tested it
It's kind of cold in the house but not unreasonable
I remember a couple years ago taking night skyline photos
I decided that the low speeds were too low - maybe they were just effectively
Set to B

click on the photo to play the linked video, I'm not good enough to embed it directly

Calling Dr. Manjiro

Here's mine (S2 Silver Dial), note it's a little different on the right side, Jon's seems to have an extra piece

Anyway, I cleaned the little spring as best I could, I didn't diassemble anything, but still no love. the spring has a little play in it, but it's near impossible to clean the
lower paet where the cam rests when the shutter is cocked, as above.

any ideas ?

The Slow speeds still function like "B"

Marc.

Hi Marc, is your photo pre or post cleaning? If it was taken post cleaning, you still have some more cleaning to do!

Hope you don't mind me using your photo, but you need to clean the surfaces on parts number 1 and 2 as indicated by the arrows so they're both completely free of any grime. I use Q tips dampened with ethanol. You need to clean the surfaces in both the shutter cocked and uncocked positions. When the shutter is fired, part 1 slides against part 2, so any grime on either surface is going to mess that operation up.

The extra piece on my my black dial S2 prevents the flash from firing when the shutter release is pressed but the shutter is uncocked. Silver dial S2s fire the flash when the shutter release is pressed regardless of whether the shutter is cocked/uncocked, and this extra part fixes that on the black dial S2s.

Additional Clue - I seem to get working slow speeds when I ever so slowly depress the shutter
until it fires, if I push it normally all the way down, it operates like "B".
If I gently push it until it just trips the shutter, I get the slow speeds

seems like I should take off the top...


Edit 1 - Well before taking off the top, I fired the shutter on slow speeds 10-20 times "gently", just enough pressure to release the shutter

then I tried my normal shutter action and, what d'ya know, it works now

maybe I cleaned enough or loosened the action by firing it gently...

Edit 2 - Working better but not 100%, I will probably open the top and see what I can see

Probably no need to IMO. Most slow speed related components are in the bottom of the camera anyway. Ensuring that surfaces 1 and 2 (as I marked in your photo) are very clean is most likely all you need to do, and I do mean "very clean" as the slightest amount of grime there can cause the slow speeds to hang. The amount of grime I wiped off to fix my camera was tiny. Good luck, Marc!

My S2 has been suffering from this for a while. I opened up the bottom and saw the stuff on the spring, but couldn't determine if it was gunk or corosion. Wht I did see was the screw at the top is an eccentric, turning it less than 1/8th of a turn relieved tension on the spring and the slow speeds returned.

Hello.
After few days the problem returned.
Clean and clean again but nothing.
So the resuls are: slow speeds dont work and i check the shutter courtains and i see the 1/1000 speed there isnt work.fire but very quickly with no gap between coutains.
If i set the speed selector slightly left from 1/30 sometimes fire at slow speeds. Also if turn the camera up side down fire the slow speeds and fire at 1/1000. I suppose the problem is not at the slow speeds but at the main speeds.maybe an axle will be little out of position.Any opinions?thanks in advance

As I mentioned above, at some point I realized that how I pressed the shutter button impacted whether I got 1/30 or B style action

I think there's something out of kilter in the stem from the button to the slow speed escarpment trigger under the bottom plate - but beyond this intuition, I don't really know

My silver dial S2 has the same issue, and a thorough cleaning of the parts described by Jon hasn't helped. Which eccentric screw is being referred to here?

Had the same issue with an S2 I picked up a couple weeks ago. On any of the slow speeds, when you press the shutter, as long as you hold the shutter button down, the shutter stayed open. When I released the shutter button, the shutter timed whatever it was set at, then closed (i.e. 1/30, 1/15, etc).

Kept firing the shutter for a couple days, shot a roll of film with only the higher shutter speeds, then eventually the shutter started working properly, IF I HELD THE CAMERA UPSIDE DOWN! It was bizarre. Worked great upside down, not at all right side up. After another day or two using it, started working properly if the camera was on it's side, either one, but would not work properly right side up. Finally, after about a week of use, it started working fine no matter what position the camera was held in.

I think for my S2, it was dried/gummy lubricants, and the fact the camera hadn't been used in many years.

Best,
-Tim

Figured it out - it's the screw next to the right angle of the spring, next to item 2 in Jon's photo above. A very slight tweak of mine is all it took.

Now, I just need to find my pointy tweezers so I can try running lens paper on the back side of the RF prism without pulling the top plate. Where did I put them? Lol
