If you fail to lubricate your car, you

AT the Chalmers factory we have

1t is not hard to keep car prop
Fly oiled and creased. A little system
i'll insure that every part which needs
brlcation receives 1t regularly. Here
re- the principal parts of a car which
Fquire attention.
Once each day, or about every one
undred miles, the crankcase should
examined to insure that oil comes
p to the level of the top try-cocll.
IMPLY add new motor oil whenever
he oil level falls below this point
he steering gear knuckle grease cups
nd steering cross rod grease cups,
hould each receive one complete turn.
aulty fabrication of the steering
ear is absolutely suicidal and it re-
uires only the simple turning of
rease cup each day practically to in
ire that you will never be placed in
anger from the failure of your steer
hg mechanism to operate. All spring
olt grease cups should be given a
ouple of complete turns each day.
he springs take the entire jolting
the car. Squeaks develop in them
cry rapidly, so their fabrication IS
ighly important. The speedometer
irving gears should also receive at
fntion daily. The speedometer be-
bmes useless if the driving gears bind
Fom undue friction through INSULT
ent fabrication. The wheel hubs,
hich must work hard whenever the
pr is in motion, should receive from
least ten to fifteen drops of motor
! per day.
About twice a week, the fan hub
hould be given a few drops of motor
rease cups and steering gear grease
ups should be given two complete
lrns. During this inspection, see
bat the steering wheel and steering
plumn each receive ten to fifteen
rops of motor oil.
Every week give the spark and
hrotle shafts a few drops of oil. In
he weekly inspection see that the
transmission case has enough oil to

Once a month, or about every one
housand miles of driving, the crank
hse should be thoroughly drained,
be oil screens and filters should be
eaned thoroughly with gasoline and
be oil well should be filed with mo-
pr oil to the top try-cock. During
ne monthly inspection, the spring

me of this monthly inspection, give
articular attention to the universal
bints. The strain carried by the uni
ersals is very heavy and to prevent
ndue wear, the universal joint cas-
hg should be filled half full with cup
rease. without fail, every one thou

At the end of every two thousand
hiles, the differential housing should
opened and about three pints of
Kle compound added. At this time.

| have found that the best system
going over the car thoroughly. is
have regular semimonthly in
bection day. There are eight main
ems which should be gone over thor
ighly in this semimonthly inspection.
First, test the compression of the
Flinders. Inspect the motor thor
lghly for possible compression leak
ge around the inlet and exhaust
hlves.
Second. go over the ignition system
1oroughly. Examine all Of the wir-
g, terminals, and spark plugs. See
lat all connections are tight and that
here are no defects in the insulation
cause short circuits.
Third, examine the water circula-
on, being sure that there are no
AXIS about the pump and it's connec-
ons. See that the fan is operating
erfectly and that the fan belt is tight
Pc that there are no'leaks about the
ater connections of the carburetor
Fourth, give particular attention l.,
pe gear shifting mechanism. See that
Il the gears move freely and that
here is no possibility of their failure
work in an emergency.
Fifth, look to the brake adjust
lent. 1t is most essential to the
lfety of both car and passengers that
be brakes work well. Examine both
ITS of brakes and be sure that they
ull equally. You want to keep the
fakes sufficiently tight to stop the
ar readily, but you also want to be
ire that they do not drag. Dragging
fakes reduce the pulling power of
