Nikon S2 Repair Information wanted.

[ZorkiKat]

Hello. Would anyone have diagrams or repair instructions for a Nikon S2? A friend gave me her late father's old Nikon. It had been badly stored for years, and the tropical climate caused the foam lining it was wrapped in to turn into goo which enveloped the camera. I have managed to repair the camera to shooting state (reset the focus, replaced shutter straps, etc) but there were three parts that I could not fix properly.

One is the frame counter- the one on this camera does not work.

Second is the flash synch circuit. It looks that someone had already modified the wiring on the synchronising mechanism on the top plate.

And third, the slow speed dial. The 1/4 sec setting is slower than it should be. The connecting gear which links the slow speed mechanism to the closing shutter is similar to the one in a Leica. Using the Leica configuration for this gear does not seem to apply for the Nikon.

The camera is able to shoot now, as/is, but I would prefer to have a working counter and a fairly usable slow speed range. 🙂

Jay that is amazing. I recall the before photo well. You've really excelled yourself this time. 🙂

Hi Jay 🙂

There is that page :

The frames counter is a basic geared thing. It takes a step on every wind motion. It must be that some gears are disconnected or totally stuck. The counter disk is a friction thing which you manually reset to 0.

But : there is a long copper spring inside the main wind shaft : if it's broken or unhooked, the frames counter won't work. Speaking of the spring visible on the photo below.

The flash sync. is quite delicate, there are wires, cams, shims and flat springs involved, so that the sync. delay can be adjusted by turning the dial around the rewind crank :

The slow speeds will benefit from a complete cleaning of everything being at the bottom of the camera : slow speeds escapement (remove it and clean it with an ultrasonic tube) and gears being under the black cover located below the shutter.

Good luck ! And congrats already. 😉

Hi Brett. Thanks! It's battle-scarred, but it shoots! 🙂

Hi H61,

Great to hear from you again! This time with a Contax-looking, but really a Leica within camera. 🙂 I should have known that that page was yours. Thank you for the information.

I took out the upper assembly of the advance lever. The Nikon S2 is really a charm to take apart- everything goes easily. Under I found this:

This part apparently needs to turn to actuate the frame counter. It has wheel shaped base with a toothed gear inside.

Removing this part reveals this:

It appears that a small part is missing. The one which transfers the movement of the eccentric shaft to the toothed wheel which moves the counter disc.

Regarding the slow speed dial, I've already taken out the slow speed mechanism and washed it, and then applied new on its pivots. In Leicas, the gear which links the slow speed mechanism to the closing shutter's spring roller. The slow speeds are almost OK, except at 1/4 sec, which behaves more like "T".

I wonder if the position of the pin of this linking gear matters in the Nikon? I know that this critical with Leicas, but with Nikon S2, how should this pin be positioned with the shutter in a fired state?

Jay

Looks like you've gone way further into a Nikon S2 than what I did !

Ah, and, no, Nico van Dijk's page isn't mine. I just mentioned it because it still exists and was enough for me so far, given what I had to do on my own Nikon S2... 😉

It was easy to go there. 🙂
I would really need an exploded diagram to see how that missing part looks like. 🙂

It may be identical to what is inside a Nikon F if the S2 frames counter is basically a Nikon SP/S3/F frames counter with manual reset.
