Hi, Jim. We tried WD-40 and grease. (Just
kidding). Belt dressing works for the forklifts, but didn't seem to help
for the big Cummins diesel engine belts. Paul Conner

Paul,
Have you tried squirting a bit of
Belt Dressing on them while they're squealing? Opening the hood and
Squirting some on them before you start? Anything like that?
Quite often that will overcome the moisture ... Jim S.

Yes, and also caused by improper tension,
especially the alternator belt. When all the clearance and marker lights are
turned on (both tractor and trailer), it puts a heavy load on the
alternator, and if the belt is not tensioned properly, causes it to
slip. It is very humid here in Mobile, AL. In the mornings when
we first start the trucks, many of the alternator belts will squeal until
the batteries are brought up to full charge, and the belts dry off
(overnight moisture). Then the squealing stops. Then they are
fine, but while they are slipping due to moisture and heavy alternator
drain, they are also wearing. If you tighten them so much that they do
not squeal when wet and batteries are not fully charged, you put too much
side tension on the pulley. Can't win. Just replace the belts
more often. Paul Conner ----- Original Message

Paul and all,
My girlfriend's brothers have
over the road trucks and do their own maintenance. They
tell me that most of their belt problems are caused by poor pulley
alignment (Even on new
Trucks from the factory)........FWIW
