Could you tell me of a way to eliminate
this?
Your coupling is probably made in
three pieces, including the sleeve, ring
and a quare piece fitting over the for
ward end of the clutch gear. There are
therefore two places where wear can
occur and cause noise in action-first,
at the Tugs of the Oldham ring and,
second, on the square sides of the
coupling. You should look at these
points and measure the clearance. If
the clearance is sufficiently great to
cause vibration and noise new pieces
should be secured to fit.
Are reIiners a SUGGEST Will one get
enough mileage to pay for their cost?
When is it best to use them, when cas-
ings are good or after considerable
wear?
RelinerS are a success and are used
by a great number of motorists. AS
to the mileage obtained. this will de-
pend upon the conditions under which
the tires are operated. Many find that
the use of reliners in worn castings
gives better results than in new ones.
What are the objections, If any, to
the two throw crank shaft?
The great objection to this method of
manufacturing the crank shaft is that
it would be detrimental to effecting o
proper balance of the reciprocating
parts. Even the use of a counterpoise
would only effect the rotative balance,
and by having it's weight properly ar
ranged only the rotating parts could
be brought into correct balance. The
reciprocating parts. however, would be
arranged In pairs, with all the parts In
the forward two cylinders going up
ward at the time when the parts in the
two rear cylinders were going down.
This would set up a longitudinal rock
ing motion which would entail consid-
cradle vibration at high speed, besides
which there would be Il tremendous
strain Oh the bolts holding the cylin-
ders to the crank case.
What advantage has one type of cool.
NY SySeS"t oNST " kbOI
Pump cooling is, of course, more pos
tive than the thermo-siphon, because
the water is forced through the water
jackets. In the thermo-siphOn system
the hot water rises to the top and so
makes its way to the radiator to be
cooled. The thermo-siphon system is
the simpler Of the two; it naturally is
cheaper and is good practice for small
motors. For large motors a pump is
essential.
Can o tell me of a good compound
that will clean the rust, scum and 9TH
err foreign matter that accumulate in
tho radiator and the cooling system?
Dissolve a half pound Of I've in about
five gallons Of water. Strain this solu-
ton and pour into the radiator and
cooling system. When this is done al
the engine to run about twenty
minutes, which is enough time for the
to do its work. 1t should then
be drained off. The cooling system
should then be washed u several
times with clean water.
In descending a long hill should one
use both tho foot and emergency brake
or just the foot brake?
In descending a hill the driver usual.
ly coasts, controlling the speed Of the
car by the service brakes. 1t is good
practice to equalize the wear on each
brake. The service brake is the one
most used. Therefore when opportuni-
ty offers 1t would seem advisable to
use the emergency brake. The term
emergency does not specifically apply
to cases Of emergency, but Is rather
an extra set of brakes for use should
the service brake fail to act at any
time. The driver must exercise judg-
in the use of his brakes and
should keep both in equally good con-
dition. The main objection to using
the emergency brake in coasting is that
when 1t is set there is nc great amount
Of elasticity to it. In going down a
hill with the emergency brakes set one
often encounters water ridges. which
are apt to snap the brake rods IL set
too tight. When a car hits these ridges
there is more or less e%longation, which
aus the additional strain.
My car consumes too much oil. Could
this be prevented by putting patent
rings on top Of tho piston and drilling
ons-eishth or one-fourth inch hole
through the piston waIIs7 Would
graphite help this any7 There 10 an
oil feed from the precision oiIer lead
ing directly into the lower part Of the
cylinder.
The use Of patent rings will help pre-
vent oil from reaching the combustion
chamber, but we suggest that before
you install such rings you determine
the aus Of the trouble. Perhaps the
cylinders are worn excessively or the
pistons worn too much. under which
conditions 1t would be better to use
larger pistons. Perhaps too much oil
is being fed to the cylinders. The
drilling of holes in the piston skirt also
will help. Graphite Is a good lubri-
cant for the cylinders and tends to all
in the microscopic holes In the metal.
