Some years back, in another lifetime, I worked part time for a good
friend
who owned a service station. Learned a trick from him about the pressed
on
alternator pulleys used by Chrysler. When doing alternator work that
required removing the pulley, when it was time to reinstall it, he would
put
the alternator in the ice dispenser for a while, then put the pulley
itself
on an electric hotplate for about five minutes. Get alternator from
freezer,
pick up pulley with channelocks, voila! Pulley falls right on, no need
to
press it on. Once the temperatures return to normal, shaft has expanded
&
pulley has contracted, now it will require a puller to remove it again.

Except for the fact that the water on the alternator might do it's own
negative magic to future performance, that is a better way to do it
anyhow.
It removes the danger of overstressing any bearings via the press
procedure.

Only "water" involved was whatever small amount of condensation could occur
on the alternator after it was removed from the freezer. To clarify, the ice
"dispenser" was one of those big chests with bagged ice in it. Pay the
cashier, open the door and take the bag out. Occasionally got a strange look
if someone went for their bag while an alternator was in there.

Those on the cutting edge bleed a lot.
