INSPECTION AND MAINTENANCE
Generator Drive Belt
The generator drive belt has the function of transmitting engine driving force to
auxiliary equipment in order to operate each mechanism.
When a bad quality belt is used as a replacement, a trouble such as abnormal
noise generation, engine stop and insufficient battery charging may be caused due
to belt rapid wear or belt breakage. When replacing the generator drive belt, it is
recommended to use the "Isuzu genuine parts".

CAUTION
The V generator drive belt is used for this engine. Inadequate tension may
lead to belt squeaking, belt breakage, or bearing damage to the water pump
or generator. When the generator drive belt is cut, electricity is not properly
generated, and it becomes a cause of overheating, so check the tension of the
generator drive belt extremely carefully.
[Cautions for belt adjustment]
Initial stretching takes place for any new belt after installation. Also, to fit
the belt into the pulley groove, adjust the belt by following the adjustment
procedure below regardless of whether performing a new installation or
reusing a previously used belt.
Adjust the belt tension in accordance with the specified procedure.
Start the engine and allow it to idle for at least 5 minutes in order to fit the
belt in.
Stop the engine, and adjust the belt tension to the standard value again.
