GENERATOR
MAINTENANCE
The
generator
normally
needs little
cate
other
than a
petiodic check of
the brushes, commutator
and collector
rings.
If
a major repai!
job
on
the
generator should
become necessary,
have the
equipment checked by a
competent electrician
who
is
thoroughly
familiar with
the operation of
electric
generating
equipment.
BRUSH
RE PLAC EMENT
Install
trew brushes when the o1d ones
are
worn
to the
dimensions shown
in
Figute 19. Remove the end bell
band and the end cover to expose the brush holders.
Remove the
three
screws holding each brush holder in
place.
Remove
the
old
brushes
and
clean the holders so
the new brushes can move
easily in their
holders. In-
stall
the rlew
brushes
in
the same manner as the
old
ones.
Always use the correct brush
as
listed in
the
Parts
Catalog
Section. Never
substitute a brush which
may appear to be the same, for it may have diffetent
ch aracteri st ics , New
brushes are shaped to fit and
seldom need salding to seat
pfoperly.
If
some
brush
sparking occurs after replacing
brushes, run the
plant
under
a
light load until
the
brushes
wear to a
good
seat.
Collector rings
acquire
a
glossy
btown finish
in
normal
operation.
Do
not attempt to maintain
a bright newly
machined
appearing surface. Otdinary cleanirtg
with
a dry, lint
free
cloth
is usually sufficient. Very
fine
sandpaper (#00) may be used to remove slight
rough-
ness.
Use
only light
pressure
on
the sandpaper, while
the
plant
is operating.
Do not use emery
or
catborundum
paper
or
cloth. Clean
out
all carbon
dust from
the
generator.
