two
field
coils are held in place by two pole
sh
oes
which are attached to
the
field frame by
large
screws.
See figure 10-13
.
The
generator is
suspended
on a bracket on
left side of cr ankcase and is
driven by
the fan
belt. The
method
of
mounting permits gen era-
tor to
be moved
in or out to adjust t
ension
of
fan
belt.
The
high output
r
at ing of the
generator
used
on all series eliminat es the need for special
service
generators except for certain police in-
stallations where unusual low speed perfor-
mance is
required.
Delco-Remy has
available,
through United Motors Service, a generator
package suitable for this kind of installation.
