1.
Draining the oil sump. Discharge the used oil through
the sump drain hose (attached to the front
of
the engine)
while the engine
is
warm. Drain the used oil completely,
replace the hose in its bracket and replace the end cap
securely.

Always observe the used oil as
it
is
removed. A
yellow/gray emulsion indicates
the
presence
of
water
in
the
oil. Although this condition
is
rare, it does require
prompt
attention
to
prevent
serious
damage.

Raw
water
present
in
the
oil
can
be
the
result
of
a
fault
in
the
exhaust
system attached
to
the engine andIor a
siphoning
of
raw
water
through
the
raw
water
cooling
circuit
into
the exhaust, filling the engine. This problem is
often caused
by
the
absence
of
an
anti-siphon
valve,
its
poor lOcation
or
lack
of
maintenance.
2.
Replacing
the oilfilter. When removing the used oil
filter, you may find it helpful and cleaner
to
punch a hole
in
the
upper and lower portion
of
the old filter to drain the
oil from
it
into
a
container
before
removing
it.
This
helps
to
lessen
spillage. A small automotive filter wrench
should
be helpful
in
removing the old oil
filter.
NOTE:
Do
not
punch
this
hole
withoutfirst
loosening
the
filter
to
make
certain
it
can
be
removed.
Place
some paper towels and a plastic bag around the
filter when unscrewing it
to
catch any oil left in the
filter.
(Oil
or
any other fluid on the engine reduces the engine's
cooling
ability. Keep your engine clean.) Inspect the old
oil filter
as
it
is
removed
to
make
sure
that
the
rubber
sealing
gasket comes off with the old
filter.
If this rubber
sealing
gasket remains sealed against the filter bracket,
gently
remove it.
When
installing the new oil filter element, wipe the filter
gasket's
sealing
surface
on
the
bracket
free
of
oil
and
apply
a thin coat
of
clean engine oil
to
the rubber gasket
on
the
new oil filter. Screw the filter onto the threaded oil
filter nipple on the oil filter bracket, and tighten the filter
firmly
by hand.
NOTE:
The
engine
oil
is
cooled
by

coolant

passages

hOl/sing
assembly
NOTE:
Generic filters are not recommended, as the
material standards
or
diameters
of
important items on
generic parts might be entirely different from genuine
parts. Immediately after an oil filter change and oil
fill,
run
the engine to make sure the oil pressure
is
nonnal
and that there are no oil leaks around the new oil filter.
3.
Filling the Oil Sump. Add new oil through the oil filler
cap on the top
of
the engine. After refilling, run the
engine for a few moments while checking the oil
pressure. Make sure there is no leakage around the new
oil filter
or
from the oil drain system, and stop the engme.
Then check the quantity
of
oil with the lube oil dipstick.
Fill to, but not over the high mark on the dipstick, should
the engine require additional oil.
A
WARNING:
Used
engine
oil
contains
harmful
contaminants.
Avoid
prolonged
skin
contact.
Clean
skin
and
nails
thoroughly
using
soap
and
water.
Launder
or
discard
clothing
or
rags
containing
used
oil.
Discard
used
oil
properly.
