ENGINE LUBRICATING OIL
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.
NOTE:
Thread size for the lube oil drain hose capped end
is JI4NPT.
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
qualified 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 absence of an anti-siphon valve, its
poor location or lack of maintenance.
1.
Replacing 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 from it into a container before removing it. This
helps to lessen spillage. A small automotive filter wrench
should be helpful in removing the old oil filter.
NOTE:
Do not punch this hole without jirst loosening the
filter to make certain it can be removed.
Place some paper towels and a plastic bag around the
filter 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. Keep your engine clean.) 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 filter
bracket, gently remove it.

When installing the new oil filter element, wipe the filter
gasket's sealing surface on the bracket 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 on the oil filter bracket, and then tighten the
filter firmly by hand.
NOTE:
The engine oil is cooled by engine coolant flowing
through passages in the oil filter bracket housing assembly.
A
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.
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 jilter.
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 engine for a few moments while
checking the oil pressure. Make sure there is no leakage
around the new oil filter or from the oil drain system, and
stop the engine. 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.
