How to wind the spring of a Bolex B8?

[joelpierre]

I have completely disassembled a Bolex B8 to clean and lubricate it.

After complete reassembly the camera, I have a problem with the spring: I can not wind the spring that only a quarter turn before it is blocking, and of course, the mechanism works only on of this quarter turn spring wound (about one second, which is very little).



I have certainly done something stupid, but I do not know what. Could it be the relative position of the gear spring should be respected?

But which one? Anything else?

I lubricated My B8 some years ago but didn't disasemble the spring. There are youtube videos on how to oil a B8 without doing it although I suppose the spring may need some kind of lube as well.

How did you disasembled the spring? I could not do so :oops:

The spring seems relaxed. It only works for a second.
