INSTALLATION
AND
STORAGE
1. PREPARATION
OF ENGINE
FOR INSTALLATION.
Before installing
an
engine that has been prepared
for storage, remove all dehydrator
plugs,
bags of dessicant
and preservative
oil from the
engine. Preservative
oil can
be removed
by removing
the bottom
spark plugs
and turning
the
crankshaft
three
or four revolutions
by hand. The
preservative oil
will then
drain through
the spark
plug holes.
Draining will be
facilitated if
the
engine
is tilted from
side to side during
the above
operation. Preservative
oil which has
accumulated
in the sump can
be drained by
removing the oil
sump plug.
Engines that
have been
stored in a cold
place should
be
removed to an
environment of at least 70°F.
(21°C.) for a period of 24
hours
before preservative
oil is drained
from the
cylinders. If this
is not
possible, heat
the cylinders
with heat lamps
before attempting
to drain the
engine.
After the oil sump has been
drained, the plug should be
replaced and
safety-wired.
Fill the
sump or external
tank with
lubricating oil.
The
crankshaft should again
be turned several revolutions
to saturate the
interior
of the engine
with the clean
oil. When installing
spark plugs,
make
sure that
they are clean,
if not, wash them
in clean petroleum
solvent.
Of
course, there will be a small
amount of preservative oil remaining
in the
engine,
but this can
cause no harm.
However, after
twenty-five hours
of
operation,
the lubricating
oil should
be drained
while the engine
is hot.
This will remove
any residual preservative oil
that may have been present.
CAUTION
Do not
rotate the crankshaft
of an
engine containing
preservative
oil
before removing
the spark plugs, because
if the cylinders contain any
appreciable
amount
of the mixture,
the resulting
action,
known as
hydraulicing,
will cause
damage to the
engine. Also,
any contact nf
the
preservative oil with painted surfaces should be avoided.
