I am on my 3rd Oriellys Optima 95 mustang alternator. Wires are hooked up correctly, pulley is in perfect line but they keep blowing the bearings out. The last one lasted 10 minutes, am I missing something or just chalk it up to Chinese parts? TIA.

If you feel the bearings are just junk, you may try swapping it out for a 6303 bearing from Fastenal. About $4 -
Good to know, it is popping the bearings and trashing the pickups every time.Comment

Dude, I put 4 GM alternators on a car a few years back, all tested good on the bench, but didnt work in the car. Once you tension-ed the belt they quit. it was stupid."If I asked people what they wanted, they would have said faster horses." - Henry FordComment

In my experience, this usually is the result of an really overly tight belt. And add to that a shitty chinese reman alternator that typically will be more susceptible to premature failure.
Pro tip: If you want a rock solid 3g/4g/6g alternator, take your failed unit to Auto Start on Main St. in Lewisville. If you don't live in the area, it's worth the drive. Or make arrangements to ship. I did the off the shelf reman thing once back in the day. No bueno. A buddy of mine that worked at a local repair shop at the time said they send their customer's bad alt to Auto Start and they never had a customer call or come back with a alt problem. Therefore, over the years I've had Auto Start do a rebuild on a failed OEM alt. on 3 different vehicles. Never had a alt problem since. Check your belt size, especially if you are bypassing the smog pump. Consider going up in size (e.g., .25") with a good grippy belt, like the Goodyear Gatorbacks. Those Auto Start guys are gurus on both auto and marine applications. I think I paid them $120 for the OEM 4g on my '03 Procharged GT. It had bearing and regulator problems.Comment

Well good news is I used the Summit tuff stuff 150 amp and it took me to goodguys and all around town with no issues. I did see a few boardmembers rides (all looked great!) but couldn't find anyone. If this one fails I will hit up the gentleman recommended, thank ya again ya filthy animals!Comment

The key is to get an American-made alternator with American-made bearings. I would not recommend getting larger than a 130amp model.Magnus, I am your father. You need to ask your mother about a man named Calvin Klein.Comment
