svnt442,
thx a lot for you help,
I gave up on the "let-make-it-original" and welded a tension pulley on the bracket..

after 14 years my olds waited she is now riding!

thx for you help, without you it would have taken me ages..

You are welcome. I'd still like to see what you did for your solution.

 

Hi

I tried to take some photos and even make a short footage,
but the light is very dark, so I will do it next time the car will be lifted.

in general, we welded another pulley just to make the belt away from the pump.
