DESCRIPTION
AND FUNCTION - The purpose of a
distributor
is to provide
current
to the
primary
winding of the ignition.coil
at
the prop
er
time
and
also to
distribute
the high tension voltage to the
proper
spark
plug.
The
br
eak
er
contacts of the di
stributor
are
connected in
the
coil
primary
circuit
so
that
the rotation of a cam opens
the
coil circuit
at
the
proper
instant
to gener-
at
e a
spark
. The
distribut
or cap
and
rotor
ar
e
arranged
so
that
the
high
tension
voltage is connected to
th
e
corr
ect
spark
plug
for
firing
each cylinder.
The
distributor
provided is of the
dust
proof type,
with
a centrifugal type
spark
advance,
and
requires little
att
ention exc
ept
to add a few drops of oil every
sixty
hours
to the oil cup as indicated by
arrow
(1)
on
the
side. At
the
same time,
the
low tension
wir
e as indicated by
arrow
(2) should be checked
for
tightness
at
the
terminals
and
for
wear
of the insulation. The high tension leads should also be.
checked to see
that
they
are
firmly
in th
eir
places on
the
distributor
cap as indi-
cated.by
arrow
(3)
and
on
the
plugs
and
in
the
coil.
250 HOUR
INSPECTION
-
After
every 250
hours
of operation,
or
twice a year,
the
cap
should
be removed and examined
for
cra
cks
or
corroded high tension terminals.
If
cracked the cap should be replaced and if
the
terminals
are
corroded they should
be cleaned
with
refined "CARBON
TETRACHLORIDE."
DO NOT
FILE
THEM.
At the same time the
rotor
should be checked
and
if cracks
are
present
it should be
replaced.
