<VV> Blower bearing oddity

[Rick Norris]

This is not unusual at all given the age of our cars and not knowing if the
previous bearing was replaced properly. I had one do it on my race car
several years ago. One year at the Mitty Spence Shepard had one climb out
so, it's not an unusual problem.

Today I broke a fan belt for the first time in about 20 years, fortunately
just as I was getting home from a grocery expedition. In the replacement
procedure, I discovered that the top of my blower blades were rubbing
against the edge of the turkey roaster cutout, indicating that the blower
bearing had migrated up enough to overtake the clearance there. I'm a little
bemused by this, as I had procured this particular blower bearing from
Clark's several years ago, installed by them in a block cover, and I assumed
that it would hold its position indefinitely.
Reverting to shade tree methods, I gave the bearing shaft a whack with a
large hammer and it dropped enough to clear the engine cover (maybe 1/8").
The engine was at full operating temp at the time, so it didn't take much of
a whack to move it. I'm curious whether this is anything like normal
behavior, or if there's something in the fan belt geometry that I need to
adjust to prevent a recurrence. I thought that the press-fit nature of the
blower bearing would prevent this sort of circumstance. Words of wisdom
would be much appreciated.

Definitely unusual... just watch it for the next 1,000 miles to see if it
moves..
