Just fitted a new alt/aircon/pas belt and noticed that the sprung self adjusting pulley is bouncing up and down on tickover. Is this normal?
If you watch the video, you can see that the the nearest pulley is obviously steady and shows a clear edge, but the small one between that and the crank pulley is bouncing. Not easy to make out I know ,but it's doing it, and also is making that slight "wrrrrrrr" sound. It clears when the revs increase, but I only have two hands, so can't demo that.
