CHANGING THE ENGINE OIL
.The engine oil should be warm. Remove the oil drain hose
from its attachment bracket and lower it into a container and
allow the oil to drain, or attach a pump to the end of the
drain
hose and pump the old oil out. Make sure the oil
drain
hose
is properly secured in its holder after all of the qld Qil has

A
WARNING:
Used engine oil contains harmful
- ~
contaminants. Avoid prolonged skin contact. Clean skin
a~d nails thproughly using soap and water. Launder or
discard clothing or rags containing used oil. Discard
used oil properly.
Always observe the old oil as it
is
removed. A yellow/gray
emulsion indicates the presence of water
in
the oil. Althqugh
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 te.$tilt
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.

THE
~IL
FILTER
Wh~nremoving
the used oil filter, you may find it helpful to
·'puifCll
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
~ould
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
~talling
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 finnly by hand.
NOTE:
Use genuine WESTERBEKE oil filters. Generic filters
. are
not recommended. • •
REFIWNG 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!
Mter 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 {>eriod
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.
