SECTION 7
CORROSION
PREVENTION
IN ENGINES
INSTALLED
IN INACTIVE
AIRCRAFT
Corrosion
can occur,
especially
in new or
overhauled
engines,
on cylinder
walls
of engines
that
will
be inoperative
for periods
as brief
as
two days.
Therefore,
the
following
preservation
procedure
is
recommended
for inac-
tive
engines
and
will be
effective
in
minimizing
the
corrosion
condition
for
a period
up to thirty
days.
NOTE
Ground
running
the engine
for
brief periods
of time
is not a substitute
for
the following
procedure;
in
fact, the practice
of ground
running
will
tend to
aggravate
rather
than minimize
this corrosion
condition.
a. As soon
as
possible
after
the engine
is
stopped,
move
the aircraft
into the
hangar,
or other
shelter
where
the
preservation
process
is to
be performed.
b. Remove
sufficient
cowling
to gain
access
to the
spark plugs
and
remove
both
spark
plugs
from each
cylinder.
c. Spray
the
interior
of each
cylinder
with
approximately
(2) ounces
of
corrosion
preventive
oil while
cranking
the engine
about
five (5)
revolu-
tions
with the
starter.
The spray
gun nozzle
may be
placed
in either
of
the spark
plug holes.
NOTE
Spraying
should be
accomplished
using
an
airless
spray gun
(Spraying
Systems
Co., "Gunjet
" Model
24A-8395
or equivalent).
In the
event an
airless spray
gun is
not available,
personnel
should
install
a moisture
trap
in the air
line
of a
conventional
spray
gun
and be certain
oil
is hot at
the nozzle
before
spray-
ing cylinders.
d. With
the
crankshaft
stationary,
again spray
each
cylinder
through
the
spark
plug
holes
with
approximately
two
ounces
of corrosion
preven-
tive
oil.
Assemble
spark
plugs
and
do
not turn
crankshaft
after
cylinders
have
been
sprayed.
