I had forgotten that I did not use all the parts in the kit.
Did not use the regulator nor diodes.
The life of such components is measured in 100s of years.
There are those that maintain a "quality" rebuild requires such
be replaced. I don't. Proof so far is that my alternator is still working
after a decade.

As far as the bearings go? Well a decade is not bad for a package that
has more than one language on it. Oh well, you mileage may vary.
Just make sure to inspect them (spin them) before installing no matter
what supposed quality you think you're buying.

It's really not hard to fix these alternators.
