Lubrication Troubles.

the fact that when tho engine runs

except when the harm has already

that the latter two are operating, and
the only way to know ia by watching
them.
ID The illustration shows the course OF
the oil In what IN known as the CON
stunt level splash system, u system
used more than any other. Other sys
TENS may vary from this. by having
nn arrangement OF tho piping SOFAS to
have the oil flow direct TO the main
bearings. while stiil others have a
hollow crank shaft, thru which the
oil flows from the main bearings TO
course of the oil up To the bearinge,
however, Ia the same on most cars as
that shown In tho illustration.
You will note that the oil In the

oil reservoir, first passes thru the
screen, then goes TO the pump. from
which II Is pumped TO the sight gauge
on the dash, from which Il flows by
gravity TO the main bearings or direct
TO tho troughs, from which II In then
splashed about by the movement OF
the crank shaft, NO as 10 get on all tho
parts which require mbrication.
We first encounter the oil In the
crank-case or reservoir. into which
II In poured thru the breather tube
Here your only problem In TO have
the oil nj tho proper level, Cars are
equipped with one OF two means to
tell this. Some cara have gauge
which will indicate the level of the
oh. Sometimes these gauges. by
sticking. will not sink with the oil.
and 30 will indicate that there is more
oil In the crank lease than there really
In. Tho gauges are practically always
actunted by float. and sometimes
this float will become puncturcd and
partly filled with oil. The result win
be that the gauge will Indicate that
there In too little oil when there is
plenty. The writer has seen many
cases where people spent considerable
money trying to overcome a smoking
engine. and the using up Of too great
an amount of oil, when tho trouble
was that they fed the oil too fast be.
cause OF being deceived by tho gauge
While many cars are equipped with
causes as above. others simply have
two pet-cocks In tho side OF tho
crank.csAe, The oil must never come
so low as not TO flow out Of the bot
tom one of these when II is opened,
nor 50 high as TO flow out OF the ton
one.
After the reservoir comes the
screen. The purpose of this is to
screen out dirt. Every particle of dirt
which does not go thru Il viii gather
on II, and In time 40 much will have
gathered az 20 prevent the oil passing
thru. In nine out of ten cases when
the oil does not circulate properly the
screen is at fault. IL should he taken
out and cleaned at least once IN every
10000 miles, and In the older cars, In
which II generally is smaller than In
the newer, oftener, In many cars tu
get at the screen Il is necessary to re-
move the bottom crank case
Next after the screen comes tho
pump. While parts Of this will some
times break, making II imperative. Il
Is ON the whole very reliable piece
OF mechanism.
After the pump comes the pressure
gauge, or sight glass. which will be !
found on the dash II you have the !
pressure gauge you should study n |
and know just what the pressure Is |
for the various speeds, ana should !
the pressure come lower. instantly |

be the screen II you have the sight !

the oil as II passes thru Il for the /
various engine speeds just as the !
pressure gauge must be watched and !
you must watch the condition Of the |
oil, When tho Oh becomes extremely |
black-pnd looks more like dirty water |
than oil, the oil In the crank case !
must be drawn out (thrre is plug |

this purpose and fresh oil substituted |
for Il.

In one thing drivers especially the !
older ones, are liable TO be negligent:
that Is In draining the old oil out Af
