recently expounded upon. Now
comes to hand the care Of truck.
In many instances the require
ments are the same. Such care
may interest only truck owners,
it would seem on the surface, but
every motorist and pedestrian Is
interested to the point that the
trucks are in good order and can
be kept from hitting him.
According to George H. Dow,
service manager of one Of the
large truck companies, the fol-
lowing advice is given
Oil should be changed from a
heavier to a lighter grade. For
heavy-duty operation in Summer
a grade of oil of S. A. E. viScosity
No. SO should be used. For nor
NAL conditions, a lighter grade
should be used. Oil should be
drained more often in Summer, as
it's body breaks down more rap
idly due to the higher tempera-
ture.
The truck should be creased
thoroughly from stem to stern.
Where there is plenty of grease
there is little wear. In case light
er grease and gear oils for gen.
eral fabrication Of the truck have
been used during the Winter
months, these should be changed
to slightly heavier grease in the
wheel bearings, transmission as
sembly, differential assembly and
universal.
The radiator and water system
should be thoroughly flushed to
be sure that all anti-freeze Solu-
ton, rust and other deposits are
removed. All hose connections
and water pump should be thor
oughly checked and the fan as
sembly adjusted to insure against
any lost motion.
Guard Against Heat.
Every precaution should be
taken against over-heating the
engine. A lever adjustment of the
carburetor should be made; gas
lines, sediment bulbs and screens
thoroughly cleaned to remove dirt
and water.
The ignition system should be
thoroughly inspected and the en-
CINE properly tuned up in this re-
Spect. The generator should be
regulated for a reduction in out
put during the Summer, when the
days are longer and the lights are
used less and when there is less
drain on the battery because Of
easy starting.
watch tire pressure carefully.
While it is vital that tires be kept
inflated to recommended capaci-
ties, yet due precaution should be
taken against over-inf1ation due
to the air expansion from the heat
generated by road friction in hot
weather.
Cleaning the chassis thoroughly
and repainting the running gear
or any part of the truck which
shows the effect Of operation dur
ing the Winter weather is phase
of truck maintenance which
should not be overlooked. Clean
illness should be insisted on under
the hood as well as without. Mod !
ern motor trucks, because of their |
beautiful lines and generally at
tractive appearance, are recog- |
nized as advertising mediums of |
definite merit. Because of this, |
vehicles should be kept looking
their best.
Long life is built into trucks by |
the use of the best and most suit |
able materials and by careful and
accurate workmanship in assem-
bly,. Important repairs should be !
taken care Of Immediately by
those possessing the proper skill
and equipment. The value Of reg
ular inspections and Of prompt |
ness in taking measures to avoid /
breakdowns and costly |
repairs cannot be over-estimated. |
AS with human beings, the pre-
vention of ills is always wiser, |
safer and more economical than |
the cure.
