me srease cups on q car should bs
divided into families according to the
speed Of the bearings they are supposed
to oil. There Is sfrst the slow moving
bearing. such AZ Is found on the sprihg
ehackles. Each joint has its grease cup
and they shoyid be looked after regu-
another family which is found on the
front axie-the steering knuckles and
steering gear. Then there Is still another
,, kind, the high speed family. These are
found on the fan. pump and generator
drives and on the transmission system,
with special emphasis on the clutch COL
lar grease cups.
Instructions Ignored.
Most manufacturers send out nicely
laid out fabricated charts which are
sometimes followed by fond and careful
owners, but are finally mislaid and for.
gotten. even by them, while the easy
going driver never pays any attention
, to these instructions in the first place.
In these charts we find perhaps a large
| number Of arrows pointing to the spring
shackles family and the instruction
reads, turn grease cup down every 400
miles. Another arrow points to the cups
otling the brake control bearings and a
| similar instruction Is given. Still
another set Of arrows points to the
clutch and motor family Of grease cups,
but the instruction reads, turn down
every nifty or seventy-hve miles. The
average man does not see the difference.
He treats the high-speed, bearings as
| ne does the spring shackle cups. Two
OF the most neglected grease cups on
any car are the clutch collar and uni
versai joint cups. This is SO largely
because they are under the footboards.
To turn down grease cup does not
mean toEturn it as far as possible and
torce every bit OF grease in the cup into
the bearing at once. It means to turn
u. down suniciently to cover, the bearing
SURFACE with grease. This can usually
oe done in turn or turn and half
Of the cup. When filing cups it is
usually well to turn the cup down as
| iar as it will go, then remove 1t and fill
| IT, turning it down far enough to cover
all the threads. on the lower half Of
the cup A grease cup should never be

on the threads. Most novices make this

smeary mess all over the grease cup and
the operators hands, and as likely as
not one or two threads Of the cup will
be. DESTROYED The threads in a grease
cup are not deep and they are meant to
be turned on about three complete
