the chasis frequently in order to see
that these adjustments are maintained.
THE wheels should be removed ana
the ball and cones inspected. If the
bearing surfaces of the cones are rough
or considerably worn or II any OF the
balls are chipped they should be re-
placed. as the cost will be slight COM
pared to the possibility of trouble de-
veloping on the road. The old grease
should be removed from the hubs anc
replaced with new. In replacing the
wheel see that it has no side play what
soever and tighten the adjusting cone
as much as possible without causing the
wheel to bind. This can be determined
bv spinning the wheel, and II 1t comes to
rest with the tire valves directly under
meath the hub it is obvious that the bah
bearings are not binding.
How to Tighten Wheels.
The rear wheels should be frightened by
setting up the lock-nuts on the axle
shafts as close as possible without strip
ping the threads, so that the wheel hups
will be tightly wedged on the tapered
ends of the axle-shafts. 1t is advisable
to remove the hub caps occasionally
throughout the season to see that these
adjustments are maintained. II this Is
not done, play may develop which will
in time cause trouble.
"It is we'll to pry the spring leaves
apart near the ends with a screwdriver
and force lubricating oil or graphite be-
tween them. This has a tendency TO
make the springs more flexible. The nuts
on the spring clips. spring perches. spring
tie-bolts, spindle arms, and spindle polts
should be frightened and eotter-pins put
In so that the nuts cannot work loose.
In fact, it is a good idea that the en-
tire car be gone over at this season and
all bolts and nuts tightened.
THE circulating system should ne
flushed out by disconnecting the inlet
and outlet water connections and allow
ing water under ordinary pressure 20
enter the filler neck, flowing down
through the tubes into the bottom tank
and out Of the radiator. The water pas
sages in the cylinder castings may be
cleaned out in like manner by How
Of water from the cylinder head to the
side inlet connection.
The carbon should be removed and
the valves ground. as after season. s
efficiency OF your engine can be i'm
proved by cleaning the carbon and grind
Ing valves.
How to Drain Dirty OIL.
"The dirty oil should be drained from
the crank case and the case cleaned by
the following operations: Remove plug
and drain off oil. Replace the plug and
pour IN a gallon of kerosene oil through
the breather pipe. Turn the engine over
by hand fifteen or twenty times so that
the splash from the oil will thoroughly
cleanse the engine and transmission parts.
Remove the plug and drain off the oil. In
order to get all the kerosene out of the
depressions in the crank case the car
should be pushed up a little incline about
the height of an ordinary street curbing.
This operation should he repeated ap-
proximately every 1.OOU miles
The spark plugs should he removed
and the points cleaned with gasoline.
After cleaning, the points should he ad-
justed SO that the gap between them is
one-thirty-second of an inch. that it.
about the thickness of a smooth dime.
Examine the cOmmutator and replace
the case and fibre assembly if the con-
facts do not appear in good condition. II
the roller Is badly worn. that part should
also be replaced If the Commutator is
dirty. or ii there is CONCEALED oil on the
parts. it may be cleaned with gasoline.
THE wiring should he carefully in
spected to see that insulation is not badly
worn and that there are good connections
at all the terminals. If the wiring does
not appear to be in proper condition 1t is
best to replace it. .
The sediment bulb underneath the gas
tank should be drained to remove any
water or foreign matter that may have
accumulated.
"If the engine is in such condition as
to require extensive adjustments it will
be advisable that such work be left to
an experienced mechanic"
