ENGINE OIL CHANGE
Engine Oil Change
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.

THE OILINTO A
SUITABLE CONTAINER
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. Call a com-
petenf 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 a siphoning
of
raw
water through the raw water cooling circuit into
the exhaust, filling the engine. This problem is often
caused by the poor location of or the lack of an anti-
siP,ho~
yalve ..
2. Replacement of the
Oil
Filter. When removing the
~
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 style automotive fil-
ter wrench should be helpful in removing
the
old oil filter.
NOTE:
Do not punch this hole without first loosening the filter
to make certain it can be removed!
Place some paper towels and a plastic bag around the fil-
ter 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. Please keep your engine clean.) Inspect the
old oil filter as it is removed to make sure that the rubber
sealing gasket came off with the old oil filter. If this rub-
ber sealing gasket remains sealed against the engine
block, gently remove it.
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 nipple, and then tighten the filter firmly
~y
hand.
3.
Filling
the Oil Sump. Add new oil through the oil filler
cap on the top of the engine or through the side oil fill.
After refilling, run the generator 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 sys-
tem, and stop the generator. 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.

NOTE: Generic fil.ters 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 fi/.ter 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.

Oil Pressure
The engine's oil pressure, during operation, is indicated by
the oil pressure gauge on the instrument panel. During
nor-
mal operation, the oil pressure will range between 35 and 55
psi.
NOTE:A
newly started,
co~J
engine can have an oil pressure
reading upwards of 60 psi. A warmed engine can have an oil
pressure reading as low as 35 psi. These readings will vary
depending upon the temperature of the engine and the load
placed on the generator.
