Belt sometimes goes off under the rain

Looking at the magnified picture above, it seems that the outer surface of the snubber is not aligned with the axis of the bolt, which would be an indication of a worn out bearing.
Or is it just an optical effect?

Hi. Yes, it is really tight.
Thank you for the tip. Unfortunately I have already mounted back the freewheel, but I note the tip. :wink:

Hello Bietrume,
It is just an optical effect. Sometimes I turn myself into a magician :mrgreen:
