You missed the fact that bearing failure is most unusual on a modern

when this last happened to you or yours?

one went in the series III alternator just after I sold it to the

Quite. Just like an electric motor. And probably the most likely bearing
to fail on any engine part after the water pump. Neither of which are fed
from the engine oil system. So an electric oil pump would be absolutely no
help there.

It was relatively common in turbochargers..

Have they got pressure fed bearings?
