GENERATOR
PERIODIC SERVICE
The generator does not require periodic lubrication.
The rotor shaft is mounted on ball bearings at drive
end and roller bearing at slip ring end, and each has a
permanent grease supply which eliminates need for
periodic lubrication. At periodic intervals, check mount-
ing bolts for tightness and belt for proper alignment,
wear and tension.
CA UTZON: When applying belt tension, apply pressure
at center of generator, never against either endfiame.
SERVICE PRECAUTIONS
Since both the generator and regulator in the standard
system and the C.S.I. generator-regulator in the
integrated circuit are designed for use on only one
polarity system (negative ground) the following precau-
tions must be observed when working on charging
circuit. Failure to observe these precautions will result
in serious damage to electrical equipment.
