Verio shutter problem

[didden]

Working on this shutter and noticed a end of spring loose around the cocking lever so removed the cocking arm and main spring and found the loose spring. I am only guessing but maybe it is broke a little bit and also guessing that it goes on the center hub and then to the other 2 nubs but not sure if broke or can be put back on. Either way which way does it really go and will a new one need to be made? Hope the pictures help tell what I am asking.
Next problem never had a main spring out and have no idea how to put the lever and spring back in so need help with this also!

Well as a SWAG, it appears that it's not an original spring. Springs like that usually have only one loop. It looks like a cocking lever.
Anyhow if the loop fit over the pin it's resting near in the second picture, it should have a straight or slightly curved section that pushes against the smaller post so it pushes the latch away from the post

Ok thanks think I got now I think but for the big one I have no idea how to put the main spring and cocking lever back in....help needed with this.
Thanks

Hi Dennis, repaired lots of shutters but not a Vario. When I was working I was repairing mostly modern professional equipment.
With a decent picture or two I think I'll be able to explain how to replace the mainspring though.
If you need to replace a spring let me know - it's not very hard to make one.

Here are a few pictures of the main spring and really have no idea how to put it back in. Not sure the pictures will help but anyway they are there.

The loop connects to the small rectangular tab on the cocking lever, in the top pic if you rotate the spring 180 degrees I think it will be correct. Try that & set it in place on it's post the orientation may become obvious(or not).

Hi Dennis, usually the easiest way is to mount the spring on the collar of the cocking lever with the hook of the spring in the notch. Locate the straight end of the spring and while holding the centre of the spring to prevent it coming off the collar you rotate the assembly to tension the spring and then lower the collar onto the shaft.
Sometimes you can lower the collar so it's only just on the top of the shaft and pull the straight end of the spring round to its location before lowering the collar fully.
If you can't manage it another way you could try is to make a loop of very thin strong wire (spring wire), loop it over the hook of the spring and use the wire to pull the hook around the collar to the notch while the assembly is already in place on the shaft.
It gets easier with practice.
Good luck.
