6.5.7.8 RE-TENSIONING OR REPLACING THE
GENERATOR SERPENTINE BELT
The generator is driven by the engine using a serpentine
belt. This belt will generally not need replacement during
the service life of the generator system. However, over
time it become loose and need to be tightened. The
proper tension can be determined by using a tension
tester to measure the deflection from a given force.
Proper alignment of all pulleys on the
serpentine belt is crucial. A chirping or
squeaking sound after replacing the
belts may indicate an alignment problem.
Always inspect and replace the belts as
recommended in the maintenance
