Kreisch... FH Seilzug gerissen.. was nun ?

Hi, guys!

I could cry... just the rope pull from the left rear el.FH is torn !!!!
My question...
Is the rope pull mechanism separable from the engine or is there only a combination of these?
How can you change this? You have to remove the window frame, too, don't you?

Oh, man...
