Lubitel 166B T-22 lens repair

[tck]

Hello

I have recently obtained a Lubitel 166B TLR with a non-working T-22 lens.

Tripping the shutter does not cause the shutter blades to move at any speed, including bulb. Otherwise the shutter "sounds right" at different speeds.

I have removed the taking lens and finished partial disassembly. I have found two problems:
1. There is a dislodged spring.
2. The sub-assembly that causes the shutter blades to open and close does not stay in proper postition. The shutter blades will cycle open and closed if you hold the control arm in the proper position.

I do not know if these two problems are directly related or not (do not want to make any assumptions).

After this first inspection, it is not obvious where, if at all, the loose spring contacts the control arm (no obvious wear marks or connection points).

Does anybody have any info on disassembly/reassembly of this lens? If not, where to obtain repair manual/info. Pictures of a "healthy" inner workings would be most helpful.

thanks,
TCK

1)Can the control arm be held in position by the spring?
2)Is the spring sitting around a post or screw head?
3)Is it a coil spring that stretches & puts tension on something when it's pulled? Or is it a "hair spring" that has a circular section and one or two hooks on it? The hooks can have a sharp curve or a very gradual curve.
It is possible that an end or hook has broken off with wear. If you can get music wire of a similar diameter you can de-temper it & make a duplicate and re-temper it.
Springs aren't usually installed in a shutter just for fun so it has to have been dislodged from something.

I would also love to know, my Lubitel 166B is also slightly... Broken? It seems like such a simple fix.

Thanks for the input.

The errant spring is wound around a post that holds down two subassemblies, and ... another spring!

I do not want to start further disassembly without recommended sequence of disassembly and reassembly.
I was hoping someone could provide photos of the inner workings, reference to a service or repair manual for this lens, & etc.

I do not posess a digital camera, so I cannot provide photos of the two issues I listed in original question.

Thanks,

That there is the inside of the camera, but not in working order, they fixed it, but the lens won't go back on it now... Now I am scared to disassemble mine without proper instructions...
