This is enlightening and interesting.
I copied your response over to this specific thread I opened on the topic:
- WHY would a hydraulic belt tensioner be any quieter than a mechanical belt tensioner?
Where the three related questions are asked:
- Is the bearing loading any different between hydraulic & mechanical tensioners?
- Are the bearings themselves any different between hydraulic & mechanical tensioners?
- Is the problem only related to the alternator tensioner or does it also apply to the AC belt tensioner?
