Hello, I’m new here in the forum and a beginner in things “on the scooter rumbasteln”. although today I desperately tried to solve the mother of the variomatics. Since the mother is so bomb-proof and I didn’t get a piece of it turned, I gave it up last end and screwed the Vario lid in again. After I was done with it, I put myself on the pc and googled how to solve the mother best without ruining anything. while I read that we nn one pulls the nut too tight (i.e. without torque key), that one can damage the crankshaft. Then of course I thought “damn!, this could be the case with me now”. Now my question as already written above: How do I recognize if my crankshaft is damaged? Or what are signs of a broken KW? mfg Scooter Super 8
