just put a new alternator in last Thursday, not even 100 miles on her. on my way home from work just now I hearing loud rattle like a fan blade hitting plastic. I got out and checked, all good except a whining noise coming from the side where my oil filter is and oil pressure is all good. 3 mins later *clunk* and belt wrapped around the fan and I'm missing a bolt from the bottom of the bracket and the pulled is snapped but still attached. WTF?! I'm def getting another alternator under warranty and new belt. but what was that whining? someone help bc I was I an accident with my other car and have to buy a new car so I need to fix this immediately!! thanks guys

 

....and there's black grease coming out of the alternator.

 

You get it from AutoZone?

 

Sounds like a catastrophic failure inside the alternator, I wouldn't worry about it since you're replacing it.

 

How tight was the belt, could you play banjo music on it?
Try this next time:

 

Take it back apart, feel all the pulleys. All should be perfectly smooth, with about no play. See if you see any sign that the rubber part that makes the crank pulley a two piece deal , is messed up. It's aligned with no rubber sticking out.

"and there's black grease coming out of the alternator." That alternator should be cast back into the chasm from which it came. Get one that leaks nymphomaniacs or cocaine or something. The only thing that could do anything remotely like that is the bearing.

Check for play in ihe ideer pullay.

 

Your rebuilt alternator had a **** bearing put in it. Get a refund not a replacement and go get one from somewhere else.

 

You notice he didn't answer post #3.

 

Busy fixing jeep maybe? LOL

 

like it would matter if he did

 

bc I was in fact busy fixing my jeep. not helpful.

 

exactly

 

all the pulleys are spinning smoothly (idler pulley is good) new alternator installed and not too tight. I got it from auto parts international (new vendor I use for the my shop) and if this one ****s out I'm just going oem. plus I'm painting the owners rigid Harley so he's refunding me everything and gave me a new one. ride home went smooth though. temp gauge a lil higher than normal, lil over 210. hmm
