LUBRICATING
OIL
DESCRIPTION
The lubricating system
is
a pressure feeding system using
an
oil pump. The engine oil
is
drawn from the oil sump by the
oil pump, which drives the oil, under pressure, through the
oil
filter, oil cooler and various lubricating points
in
the .
engine. The oil then returns to the oil sump to repeat the
continuous cycle. When the oil pressure exceeds the
specified pressure, the oil pushes open the relief valve
in
the
oil pump and returns to the oil sump, keeping the oil pressure
within its specified range.
Oil
Pressure
The engine's oil pressure, during operation,
is
indicated
by the oil pressure gauge on the instrument panel. During
normal operation, the oil pressure will range between 25 and
85
psi.

1.
Draining the Oil Sump. Discharge the used oil through
the sump drain hose (attached to the front
of
the engine)

NOTE:
Generic filters are not recommended. as the mater-
ial standards

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 oilfilter.
3.
Filling the Oil Sump. Add new oil through the oil filler
cap on the top
of
the engine. 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.

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.
2.
Draining the Oil
Filter.
Back off the drain plug until oil
flows from the drain (into an appropriate container). After
draining, remove the filter and wipe off any excess oil.
Tighten the
drain
plug.
When installing the new oil filter element, wipe the
filter's O-ring gasket's sealing surface free
of
oil and
apply a thin coat
of
clean engine oil to the rubber O-ring
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.
