Engine Oil Change (to include filter)
1.
Draining the Oil Sump
Discharge the old oil through the sump drain hose
(attached at the front of the engine) while the engine
is still warm. Drain the old oil completely, replace
the hose in its bracket, and replace the end cap
securely.
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 to prevent serious
damage. Call a competent mechanic should water
be present in the oil. Raw water present in the oil
can be the result
of
a fault in the exhaust system
attached to the engine, and/or water siphoning
through the raw water cooling circuit into the ex-
haust, filling it up into the engine.
2. Replacement
of
the Oil Filter
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 into a
container before removing it. This helps to lessen
spillage. A small style automotive filter wrench
should 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 left in the filter.
(Oft or any other fluid on the engine reduces the
engine's cooling abnity. Please keep your gener-
ator's engine clean.) Inspect the old oil filter as it is
removed to make sure thatthe rubber sealing gasket
came off with the old oil filter. If this rubber sealing
gasket remains sealed against the engine block,
gently remove
it.
The replaceable cartridge-type oil
filter requires no cleaning inside, so it may be
proper1y disposed of.
When installing the new oil filter element, wipe the filter gasket's sealing surface on the engine block 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 stub, and then tighten the filter firmly by hand.
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 normal and
that there are no oil leaks around the new oil filter.
