My window no longer twitches, because the rope hoist has jumped off the roll and he did so because the intake of the Bowden train has broken. Since it is quite time-consuming to get to the place and smart can no longer supply spare parts, I had first attached a beer lid, which could actually replace the defective recording for some time (picture 01). Meanwhile I got a printed spare part. But now I fail to replace it. How do you solve the old roll, which is so unfavorably installed behind the welded side impact protection (pictures 02 and 03, from diagonally below)?
