c) Checking Belt Tension
CAUTION
Checking the tension and changing the serpentine belt should only be performed with
the engine off.
Check belt tension every 1000 hours, or once year, whichever comes first. A belt that is too tight is
destructive to bearings of the driven part. A loose belt will slip and cause inefficient operation of the
part being driven as well as wear to the belt.
CAUTION
Inspect and replace the belt if it has unacceptable cracks, is frayed, or has pieces of
material missing.
Belt tension may be checked by hand. To do so, manually depress the belt with an index finger to
determine the amount of belt deflection obtained. When a force is applied at a point halfway between
pulleys on the longest span of a belt, there should be no more than 1/2 inch of deflection attained.
Refer to the engine manufacturer’s operation manual for checking belt tension and changing worn
belts.
