bent water pump shaft

[k. putman]

With the tires spinning, engine RPM's up. Then the car hooked, loading the engine and stressing the belt. It sounds like he has a serpentine, which will have more contact than a vee, at the end of the shaft. So the bearing, and coolant to some extent, supported the stub holding the impeler and allowed the damage at the other end. I would like to know about seal damage and weep-hole leakage if it did occur this way.

Or maybe the shaft is not bent...but the flange that holds the pully was "tweeked" on the shaft because of the same type stress. This may be more likely because there is not a lot of shaft that extends from the housing.

That's why I don't do Autozone...
