Well I thought I had it tightened, put everything back together and it all loosened up in 2 miles so I limped back home. Guess I will have to take it out of vehicle get woodruf key and tighten it better. That or get a rebuilt alt. Thanks for info. One good thing to come out of this, the upgrade for fan and clutch will be a cinch. Any tips to take alternator out or just a matter of unhooking battery and electrical connections and 2 bolts holding it on.
