be
warm.
Remove
the
oil drain
hose
from its attachment bracket and lower it into a container
and
allow the oil

oil
contains
harmful
contaminants.
Avoid
prolonged
skin
contact.

skin
and
nails
thllroughly
using
soap
and
water.
Launder
or
discard
clothing
or
rags
containing
used
oil.
Discard
used

properly.
Always observe
the
old oil
as

is
removed. A yellow/gray
emulsion indicates
the
presence of water
in

oil.
Although
this condition
is
rare,
it
does
require prompt attention
to
prevent serious
damage.
Call a competent mechanic if water
is
present
in
the
oil.
Water
present
in
the oil can
be
the result
of a fault in
the
exhaust system attached
to
the
engine and/or
a siphoning through the water cooling circuit into
the
.
exhaust,
filling
it
up
into
the
engine.

OIL
FILTER
PN#048078
I;;nll.111:11111:1
THE
OIL
FILTER
When removing the used oil
filter,
you
may
find
it helpful
to
ipunch
a hole in
the
upper and lower portion of
the
old
filter
to
drain
the
oil into a container before removing
it.
This
helps
to
lessen spillage. An automotive
filter
wrench
~hould
be
helpful in removing
the
old
oil
filter.
Place
some
paper
towels
and a plastic bag
around
the
filter
when
unscrewing
it
to
catch
any
oil that's in the
filter.
Inspect
the
old
oil
filter
as
it
is
removed
to
make sure that the rubber sealing gasket
comes
. off with the old oil
filter.
If
this rubber sealing gasket remains
sealed against the oil filter
adapter,
gently remove
it.
When
installing the
new
oil filter element, wipe the
filter
gasket's
sealing surface
on
the oil filter adapter free of oil
and
apply a
thin coat of clean engine oil
to
the
rubber sealing gasket
on
the
oil
filter.
Screw
the
filter onto the threaded
oil
filter
stub,
and
tighten the filter
firmly
by
hand.
NOTE:
Use
genuine WESTERBEKE
oil
filters.
Genericfilters
are
not
recommended.
'
REFILLING
THE
OIL
SUMP
Add
fresh oil through
the
valve
cover.
After refilling
the
oil,
run
the
engine
for
a
few
moments
while
checking
the
engine's
oil pressure. Make sure there
is
no
leakage around
the
new
oil
filter
or from
the
oil drain
system.
OVER-FILLING
CAUTION:
The
oil
sump
on
this generator's engine
can
unintentionally
be
over-filled!
After shutdown, the oil in the engines internal
passages
can
linger and take a number of hours
to
drain back into
the
oil
sump.
Allow at least a
few
hours
for
the
oil
to
settle back into
the
sump before checking the dipstick. An overnight period
will provide
an
even more accurate dipstick
reading.
(Re-starting the engine
is
not a problem
as
the
engine's
internal passages
are
well
lubricated).
Over-filling the engine's sump
will
result in erratic operation,
and/or a smokey white
oil
laden exhaust, hard starting
and
possible
no
start.
