d. Alternator and fan belt adjustment
Refer to 2-1; Para. 8 for belt adjustment instructions.
NOTE: Replace fan belts with a matched set.
e. Electric Governor System Adjustment
The magnetic pickup and control box have critical adjustments which can affect engine performance
and generator output. Actuator-to-fuel control lever adjustment can also affect engine performance.
The engine should be equipped with a separate overspeed (overtemperature, or
overpressure) shutdown device, to protect against runaway or damage to the
engine, with possible personal injury or loss of life should the mechanical
governor, or electric control, actuator, fuel controls, driving mechanism, linkage,
or the controller device fails.
When the complete system is to be checked, and /or adjusted, a definite sequence of procedures
should be followed:
First - Check or adjust actuator linkage.
Second - Check or adjust magnetic pickup.
Third - Check or adjust electric control box
