[Shotimes] RE: Re: Alternator

[Carl Prochilo]

I replaced the belt yesterday after I inspected all the pulleys, which all
(idler, AC and ALT) spin freely.  Car started right up and ran fine.  AC
blows cold, system was charging from best I could tell.  At some point
yesterday, the new belt jumped off again!!  No visible signs of damage.  I
had one guy take a quick look at it.  He came up with the same
observations I had about the pulleys spinning freely.  So either I didn't
tighten the belt enough, possible since I didn't have a tension
measurement tool handy, or there's something else amiss like the crank
pulley might have an issue that I can't detect.
