The belt isn't just getting loose; the pulley halves actually rotate
with respect to each other. I verified that by making some matchmarks
with a felt pen last time. Once it loosens up, I can take up the slack
in the belt by turning the pulley halves by hand, and I don't think
the pinching bolts were loose. Of course, I still need a pair of big
wrenches to properly tighten the belt after the slack is gone. I don't
have the special compressor pulley wrench yet, but I've managed to get
the bet tight enough (until the pulley slips again) with big ol'
channel-lock pliers.

I'll look into that next time I work on my truck. If it looks like
that's my problem, maybe I'll be able to fix it without needint to
remove the pulley (which looks like it'll be difficult or impossible
without removing either the radiator or air compressor).

I don't know. It's the belt that was on the truck when I got it, and
I'm not the first civilian owner.
