Les,

Whether you get shields or seals, they don't keep crud out of the bearings
for very long. I've gone to using Abec 1s and simply replacing them after so
many hours. The roar does get quite a bit louder. I was using 4 PCs at one
point, rotating them through the rebuild bench on a regular basis. Enough to
make one want a Perske or Columbo.
