Issue with Zenit E shutter disassemble

[Nedugo]

Hi ! *new here*

I'm working on a Zenit E and I want to remove the top part, I followed a manual I found
But I'm stuck with the shutter, I can't remove *part 103*, it's a left-hand thread but the part doesn't unscrew, it turns by making odd clicks, I don't want to force on the mechanism.
So if someone can explain to me what I did wrong and how I'm supposed to deal with it, that would be great.
Thank you by advance

Are you bearing down too hard as you turn it?

Try to cock the shutter first to prevent part 103 from turning

The threads are likely sealed with thread locker, use Acetone to dissolve it.

Okay, I will try these solutions, thank you !
