ENGINE

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.

Wbyn

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.

CHANGING

THE

ENGINE

OIL

The

engine

oil

should

be

wann.

Remove

the

oil

drain

hose

from

its

attachment bracket

and

lower it into a container

and

allow

the

oil

to

drain,

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.

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

if

water

is

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 through

the

raw

water

cooling

circuit

into

the

exhaust, filling into

the

engine.
