Vacation time, so camera repair time
Before starting to disassemble the Exa original that Attila was so kind of sending me, I've started to try to fix the two non-working EXA500 that I own, to get a feeling on how the Ihagee engineers work.
Later on I'll put some pictures on how to disassemble the EXA500. It's quite laborious, but there are no reversed screws (as in the Spotmatics).
It took me a couple of hours to have both cameras fully naked. (Photo porn below, so please go on at your own risk ).
The two cameras have similar mechanics (but not the same).
By comparing the two, is easier to spot faults. See the folded lever at the right one:
When opening the second one, a screw head fall into the table...
By comparison, it's easy to spot where it comes from:
Now, looking for info on the curtains. I don't understand yet how they work. But I love the vertical design instead of the more common horinzontal one.
More to come...

Thanks Bill, maybe yours is a more recent one. Mines are serials 352629 and 320518 (the serial# can be seen in the bottomside of the body, once the cover opened). Even being the same design, both have different mechanisms in some places.
Exakta was the "pro" line whilst Exa was the consumer one. And the EXA500 was the last produced so maybe the marketing guys decided to rename it in some moment to give it more appeal...

Luis,
First try to fix the "parts" camera. Maybe is not so damaged.
I've been able to open two EXA500s and I've stopped before the shutter mechanism. Both have it broken, one is wildly stuck with a folded lever (brute force approach of the previous owner) and the other one is wildly broken. I'm waiting for a couple of service manuals. Arriving there is not difficult but the shutter mechanism working (in the EXA500) is not evident.
Which models are you trying to fix?.
Good luck in your quest!

I'm sorry to hear of your problem.
You do need parts. Perhaps these can be made from brass ?
Mine are VXIIb's, and also, maybe, the experience will help in CLA of a VX which is in better condition. _________________ I like Pentax DSLR's, Exaktas, M42 bodies of all kinds, strange and cheap Japanese lenses, and am dabbling in medium format/Speed Graphic work. |

@ Luis:
The VX, Varex IIa, IIb and VX 1000 are all very similar to each other mechanically and if you manage the IIb, you'll manage the VX.
Removing the mechanics from the body is virtually identical for all these models although there are three things you must remember:
1. When removing the lens mount, watch out for any spacers/shims located behind it - sometimes they/it can be paper. Take note of where they go and keep them safe if your camera has them.
2. Cock the shutter before removing the cocking arm - you can refit it once the top plate is removed. Don't release the shutter without the arm being fitted as you may find that various parts will fling themselves wildy in all directions....
3. After cocking the shutter, fully wind the slow speeds dial - this is pretensioned so don't remove the knob with it unwound as it will wind down further and it will be very difficult to refit it later. Again, don't release the shutter until you refit the parts you remove.
I can show you where all the screws that you need to remove in order to separate the mechanics from the body shell are should it be necessary.
Something else to consider is that because the mechanisms can be separated from the body, if you have a scabby looking body with good curtains and mechanics and a mint body with poor curtains, you can swap them over as long as both bodies are the same model. If you intend to use the camera, check the focusing at the film plane if you do that though as it may be affected. |

Miles Upton is highly respected in the Exakta field so buying his manual would be a very good start - I have reprints of the original factory manuals for the Varex IIa and VX 1000 but in German and so was considering buying his manual myself.
If you need shutter curtain material, I can recommend Aki Asahi - he also does light seals and camera covering materials:

I've never had occasion to work on an Exa, but in general I have found that stiff shutter curtains are a common problem in East German SLRs of that period (Exaktas, Pentacons, Praktinas etc). There's a pretty good chance that the camera will run better with fresh curtains....
Thanks for posting those photos by the way, they're great!

Hi Rick, thanks for the advice. These seem to have the shutter curtains in good shape. I can exercise them by turning the corresponing sprockets, and they show quite fine.
The problem with both of them is the mechanism to wind the curtains and load the firing spring. In one case it's stuck, in the other just broken.
I've ordered reprints of the original breakdown and repair manuals, so I'm waiting to receive them to be able of progressing (without damaging anything).
I'll keep posting as sonn as I get some progress.

Regarding shutter curtain condition, it can be a bit of a lottery although I've found that of my collection, it's been the newer VX 1000 that has been more consistent in this.
I have the following:
VX - shutter fires OK but curtains starting to crack.
Varex VX - curtains excellent with no cracks, stiffness or pinholing.
Varex IIa late - curtains excellent with no cracks, stiffness or pinholing.
Varex IIb x 2 - curtains badly cracked on both.
VX 1000 x 3 - curtains excellent with no cracks, stiffness or pinholing. |

I got my new VXIIb for "parts", and, unfortunately, it is in wonderful shape. So I got a "user" not a "loser". Its in much better shape than my old VXIIb. The shutter curtain is perfect, the only things wrong I can see is that it sticks a bit on winding (though that works) and it won't cock when the speed is set to 1/60.
The curtain on this one seems like ordinary fabric, while my old VXIIb is rubberized. _________________ I like Pentax DSLR's, Exaktas, M42 bodies of all kinds, strange and cheap Japanese lenses, and am dabbling in medium format/Speed Graphic work. |

We have a pretty busy and cheap local photo shop. Relative easy to find eastern block products just need to visit frequently they are not sitting much time on shelfs. Before I establish this site they kept plenty of good lens for months without buyers. People would buy only Nikkor etc. Now it is dramatically changed, thanks for all of us!
