CAPACITY OF ENGINE SUMP
The
engine lubrication system
has
a total capacity of 9 quarts
Ofl
oil,
with
the
oil
filter accounting for 1 quart of that total. The engine
oil
sump
(crankcase)
has
a capacity of 8 quarts. The engine must
not
be
operated with less than 5 quarts
in
the sump. For extended
flights, the engine
oil
level should
be
at
8 quarts.
OIL AND OIL FILTER CHANGE
After the first
25
hours of operation, drain
the
engine oil sump
and
replace the filter. Refill sump
with
straight mineral
oil
and
use
until a total
of
50
hours
has
accumulated
or
oil
consumption has
stabilized; then change to
ash
less dispersant oil. Ashless dispersant
oil
(and
oil
filter) should then
be
changed
at
time intervals set forth
by
the
engine manufacturer.
NOTE
During
the first
25
hour
oil
and
filter change, a general
inspection of
the
overall engine compartment
is
required.
Items
which
are
not normally checked during a preflight
inspection should
be
given special attention. Hoses, metal
lines
and
fittings should
be
inspected for signs of
oil
and
fuel
leaks,
and
checked for abrasions, chafing, security,
proper routing
and
support,
and
evidence of deterioration.
Inspect the intake
and
exhaust systems for cracks, evidence
of
leakage,
and
security
of
attachment. Engine controls
and
linkages should
be
checked for freedom of movement
through their
full range, security of attachment
and
evidence
of
wear. Inspect wiring for security, chafing, burning,
defective
insulation, loose or broken terminals, heat
deterioration,
and
corroded terminals. Check the alternator
belt
in
accordance with Maintenance Manual instructions,
and
retighten if necessary. A periodic check of these items
during subsequent servicing operations
is
recommended.
