Removing bottom cover on Zeiss Contina II

[SalveSlog]

The film won't turn the sprocked weels, so I think the mechanism needs cleaning and lubing. At least I want to have a look inside to see what I can do. But I'm stuck on how to remove the film advance wheel..

The two holes in the wind knob suggest they are for a spanner so assume hold the shaft from inside the body and unscrew the knob, much like 35mm SLR rewind lever removal.

The 2 holes couples to a wheel in the everready case. I don't think they are for removing.
The only possibility I can see is to remove also the top cover to take out the spool. Then try to make a tool that goes through the hole for the axis of the spool in the top to the inside of the wheel. I suspect that that can be turned clockwise to remove the weel. I'd be able to make a stick of ebony that is allowed to be 6mm thick but if that will be strong enough, I don't know. At least it won't scratch anything.

Did you find this page? Talks about jam ups, top plate removal.

Looking at the image you provided- I would think the cover on the right should come off, might be held in with some glue, or even grime. Is there anyway to use a thin screwdriver to give a gentle pry? I would expect screws to be underneath it. Somewhat like covers I've seen on the Retina.

Thank you, but mine is not the IIa model. It's the plain II (and the same as Ikonta 35 later named Contina I). The film advance is different on mine: a wheel at the left bottom.

Zeiss Ikon Contina II:

On the Kodak Retina II with advance Knobs and Rewind Knobs: The advance Knob is Reverse Threaded, so unscrews in the opposite direction. Drove me nuts until I read that. I just don't see from the photo what else is holding it in.

 

[SalveSlog]

I can get it loose clockwise but after 2 turns the rewind release button in its center seems to hold it.

The only other thing I can think of is that the metal ring shown in the interior photo can be unscrewed. You might send an Email to Rick Oleson, look up his website.

Several years ago I purchased a repair manual for Compur 00 shutter from Photobooks. The cover of the manual matched the listing, a reprinted National Camera Repair manual. On the first page it stated "overhaul of the shutter was covered in the previous manual and this one is concerned with the attaching mechanisms found in cameras it is used in. I have never given Photobooks a second thought since as the operator does not know cameras or how to repair anything. I have seen other errors in their listings that made me wonder what information was actually contained under the cover.
Search engines have changed to show what the programmer thinks you want by the terms you search for. Gone are the excellent search that Google provided when they started that would show you the exact term hits. A anyone's search for Zeiss Contina II get 99% hits for the IIa.

I attempted to purchase a Kodak Shutter Repair on DVD, Joyce said she could not find a good copy so I ask for a printed version. After 7 business days and never receiving an invoice for the manual I requested a cancellation which she immediately accepted. Good luck getting a copy if its the correct manual.

I got excellent service from John when he was alive.

Try sending an Email to Mike Elek. He did an incredible job on my Contax II. Worth a try.

I know this is an old thread as I came looking for an answer to the same question.
Thanks to melek and a service manual for the Contessa (533/24) I was able to take the bottom off
- The film advance wheel has the clutch button in the middle
- The button can be removed by unscrewing it (using soft pliers)
- There is a hidden set screw underneath
- Film advance wheel unscrews (L threaded)
- Carefully remove the 4 screws and remove the bottom. Take pictures as some pieces might come out or drop
