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 ililirl, 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 old oil has
been drained.

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.
Always observe the old 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 t<;>
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.
INLET FUEL FILTER
To ensure clean fuel into the fuel lift pump, there is a small
in-line fuel filter connected to the fuel module. This filter
should be replaced every 250 hours of operation.

When removing the used oil filter, you may find it helpful to
punch 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 should be
helpful in removing the old oil filter. Place some pll,per 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 tlie 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. Generic.filters
are not recommended.
REFILLING THE OIL SiJMP
Add fresh oil through the valve cover. After refilling the oil,
run the,engip~
for a few moments while checking the engine's
oil presslire. Make.•sure there is no leakage around the new
oil filter or from the oil drain system, and then stop the
engine. Then check the quantity of oil with the lube oil
dipstick. Fill to the FUlL mark on the dipstick.
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 pe1iod
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.
