Drive Belt
Belt Tension
The fan drive belt should be properly adjusted at all times.
1. Install the belt tension tool on the drive belt and check
the tension.
A loose drive belt can cause improper generator, fan and
water pump operation. A belt that is too tight places a
severe strain on the water pump and the generator
bearings.
A properly tensioned drive belt minimizes noise and also
prolongs the service life of the belt. Therefore, it is
recommended that a belt tension gauge be used to check
and adjust the belt tension.
Any belt that has been
operated for a minimum of 10 minutes is considered a
used belt, and when adjusted, it must be adjusted to
the used tension shown in the specifications.
2. If adjustment is necessary, loosen the generator
mounting and adjusting arm bolts. Move the
generator toward or away from the engine until the
correct tension is obtained. Remove the gauge.
3. Tighten the generator adjusting arm and mounting
bolts. Install the tension gauge and recheck the belt
tension.
