b.
The
slip
ring
end
head
provides
the
mounting
for
the
rectifiers
and
rectifier
mounting
plate,
output
and
auxiliary
terminal
studs,
and
the
brush
and
holder
assembly.
The
slip
ring
end
head
contains
a
roller
bearing
and
outer
race
assembly
and
a
grease
seal.
c.
The
rectifiers
used
in
these
units
are
rated
at
150
peak
inverse
voltage
(P.I.V.)
minimum
for
transient
voltage
protection.
Three
positive
rectifiers
are
mounted
in
the
rectifier
mounting
plate
while
the
three
negative
rectifiers
are
mounted
in
the
slip
ring
end
head.
Each
pair
of
rectifiers
is
connected
to
a stator
lead
with
high
temperature
solder.
The
stator
leads
are
anchored
to
the
rectifier
mounting
plate
with
epoxy
cement
for
vibration
protection.
d.
The
stator
contains
a special
lead
which
is
connected
to
the
center
of
the
three
phase
windings.
The
stator
has
been
treated
with
a
special
epoxy
varnish
for
high
temperature
resistance.
e.
The
rotor
contains
the
slip
ring
end
bearing
inner
race
and
spacer
on
the
slip
ring
end
of
the
shaft.
The
rotor
winding
and
winding
leads
have
been
specially
treated
with
a
high
temperature
epoxy
cement
to
provide
vibration
and
temperature
resistance
characteristics.
High
temperature
solder
is used
to
secure
the
winding
leads
to
the
slip
rings.
f.
The
drive
end
head
supports
a sealed,
prelubricated
ball
bearing
in
which
the
drive
end
of
the
rotor
shaft
rotates.

OVERHAUL
OF
ALTERNATOR.
When
repairing
the
alternator,
complete
disassembly
may
not
be
required.
In
some
cases
it will
only
be
necessary
to perform
those
operations
which
are
required
to
effect
the
repair.
However,
in
this
section,
the
complete
overhaul
is covered
step-by-step
to
provide
detailed
information
on
each
operation.
In
actual
service
practice,
these
operations
may
be
used
as
required.
