Seen I different thing today , a 753 alternator locked up the rear bearing and spun the back half the alternator sheering the 4 small diameter bolts that hold the two halves together and ripped about 10 of the wires in the wiring harness which runs right next to the alternator , have have never seen this one before and it was a sight to see , with the cab up and the motor running the back 1/2 the alt was spinning around , was able to disconnect the harness from the engine and get enough slack under the cab the splice in some new wires ----------I thought it should have flung the belt before that happened , any body seen that one before

Holy crap! i have never seen that before and i never would have thought it could happen. The bearing is only quite small and the 4 bolts i figured would be quite strong. Its rare for a bearing to lock up like that too, sure they go gritty but very rare to simply lock up, especially when moving. On items that were exposed to the weather for some time i have had this happen but not to that extent.
I could see the belt being able to hold enough force to do the damage if its the correct tension, its a shame it didn't just slip or break, it could have saved you some money and heart ache.
Hope it didn't cost too much to fix.

It was $165 for the alternator from dealer , which isn't bad as the local starter shops charge $125-$150 to rebuild one , a new belt and 20 butt connectors and a roll of wire , under $200 parts and 2.5 hours labor , not bad I thought for a real disaster , when I first looked at it I thought oh no!

You're lucky it didn't do more damage to the wiring, i have a new respect for the newer machines after i saw just how much wiring they have compared with my old clunker!
Did you get any piccies of it at all? i know its not something you really thought about, i know i'd be uttering a few 4 letter words at it and just wanting to fix the rat next of wiring that was now attached around the alternator.
That price seemed pretty reasonable indeed for a new alt.
If you service your own you can do it pretty cheap. Bearings are about $5 for the pair, reg and brushes are about $30. Easy!

I would think this is quite rare, being that the bearing is applying torque (when they seize) on a much smaller diameter circle then the the bolts are on.
I needed one rebuilt and my local starter shop said we don't fix those. (refering to the Korean Mondo) and handed me a Delco that bolts right on for $65.
However I did have to install a diode in one wire because the current was back feeding to the fuel solinoid on the 853 and the engine would no shut off.

When I was a equipment rental service manager I use to hunt down alternative solutions at lower cost , but find now on my own that time is money and sometimes it's better to just get bite the bullet for the quickest fix , the travel time running around gathering parts sometimes exceeds the time spent making the repair ----------I really like my job , it gets frustrating at times as it all comes at the same time and you can't do everything , you fix other peoples nightmares all day and go home and take care of your own , it's kinda like a cross between CSI ( troubleshooting ) and McGiver ( infield repairs )--------and now it's turning into The Matrix ( high tech electronics)

I know what you mean, but we had alot of delco alternators, I have retrofit several more, and I keep rebuilt one on the shelf. So if ones dies and I have time, I'll make a delco fit if I can
