My issue with the bearing is that the one side of the bearing had the retainer 
ring broke and fell off.  Im sure I could get another ring from a replacement 
bearing which Ill do.  But for now I ordered two other full sheaves from US 
Tower.

Have you tried squirting it with WD-40 or a similar elixir to see if you can
