Lubrication Some New
Suggestions.

In spite Of the inslstence Of motor
car manufacturers and service men on
the vital importance OF fabrication as
it affects the life Of the vehicle. 1t is
doubtful IL the average car gets all
that 1t really needs in this connection.
Nor Is the reason far to seek; we
have upward Of a million new car
owners in this country every year.
and they must learn the lessons that
the preceding motoring generation
has come to take as a matter OF
course. Further. we are learning all
the time in every branch Of the auto
mobile industry and the science of
fabrication is constantly developing.
SO 1t Is that the wise motorist reads
all that he can find in regard to lu-
IRRIGATION, and here are q few sug-
gestions that may help him:
To begin with, let us address a few
words to car owners wo are still
using grease In the transmission. Oil
is the proper lubricant for the gear
set. The gear teeth cut a path
through the heavier lubricant and
then proceed to revolve In thin air.
to their great detriment. In addition.
grease has the unfortunate charac-
teristic of carrying dirt and foreign
matter of any kind into the gears or
wherever else 1t may be used. In
cold weather grease Is simply impos-
sible. After the gearset has been in
operation for a short time the grease
becomes packed against the walls Of
the housing, and the gears them
selves get no fabrication whatever
So make this your first fabrication
law: Use transmission oil of the prop
er grade in this part Of the mechan-
ism.
Not many years ago grease cups
were used in all parts of the me-
chanism for lubricating bearings.
etc. Now grease is not the best
lubricant for this location. because
it has characteristic of getting
hard in the cup. so that the latter
cannot be properly turned down.
hence that part does not get ade-
quate fabrication.
1t is for this reason that more
and more cars every year are being
fitted with oil cups in many loca-
tons. though the familiar grease re-
ceptacle still persists on many parts
OF even the best cars. The owner
who really understands his car
toiu lHdl Oll
is better than grease, but perhaps
he does not know that il he so de-
sires he can substitute oil cups for
the grease variety. Within the
past year or SO a number of very
ingenious oil cups have been placed
on the market. embodying systems
of gradual feed whereby the oil is
permitted to leak out gradually in
stead of running away in a single
day. as used to be the case. That
was always the trouble with oil
cups; you had to keep filling them
up each day. Some OF these new
cups have CONSTRUCTED passages
which permit only a slow flow of
oil. while others have what are
known as wick feeds. wherein a
wick picks up the oil from the cup
and allows il to reach the part to be
fabricated gradually. Some of these
cups need replenishment only once
or twice in a running season. An
other advantage of the wick feed is
that. since il operates by capillary
attraction, ii does not carry dirt or
foreign matter to the bearing sur
face, even II it is present in the
cup. As a matter of fact the wick
feed cup is probably the nearest
thing to having the parts running
in oil.
Naturally. the different parts of
the mechanism require different
grades of lubricants or better say
oils. For the gearset. differential
and rear axle a heavy oil is the
proper lubricant. Other parts of
the mechanism do better on the
ordinary cylinder oil. For the aver
age car two grades of oil will prac-
