MOTOR QUESTIONS

4 @. Is n possible for a differential
10 start humming IL the wheels are
not running true2 II appears on my
car that axle shaft alignment can
Affect dihferential alignment because
there 10 only the wheel support and
diffsrential support for the shafts.
Under these conditions couldn't the
above condition exist?
) A. II can, in q floating axle, be-
cause II the wheel bearings are bad
ly, worn the axle shaft moves with
the wheel and since there 10 no In
ner support except the differential.
the latter will be affected. The con.
dition will be aggravated IL there Is
the least play In the differential as
o unit.
Q. My car has been run over IT,
900 miles with practically no atten-
ton. Now have nothing to COM
plain about either in power-speed
or 80 on. but the local garage ad-
vises me to have the carbon re-
moved. the valves ground and a lot
OF other work. Do you think II ad
visable to have any work done IL
the car runs we'll?
A. II you are satisfied with the
running Of the car and 1t seems to
have no symptoms OF trouble, why
go TO the expense and bother of
grinding valves and doing other
work? Leave It alone. so far as re-
pairs are concerned: simply lubri-
cate all parts well.
o. Can q modern steam car travel
i as fast as q gasoline ear? / mean
standard cars. Does a steam car hold
tn a vvorld,u hnaed rRcord7
A. The modern steam car can be
beaten by dozens Of gasoline cars OF
standard make. A gasoline car holds
the worlds speed record for all
distances
@. I recently removed the. eyIin-
der head Of my engine and ground
the valves and cleaned out the car
bon. put the head back right. but
now there is misfiring. which q
friend of mine says is caused by
water leaking into the cylinders be-
cause the gasket doesn't Mt just
right. Is this possible? 1t seems so
to me because I touched nothing but
the valves and not the tappets.
A. 1t is possible that a water leak
due to a poor gasket is the cause
Of the trouble. II the leak Is small
you will notice the mfsfiring at low
speeds aud not SO much at high
speeds. Remove the head and in
stall a new gasket: don't try to
straighten out kinks in the old one.
@. What is your opinion Of the disc
steel wheels? Do you think they are
better than the wire wheel or the
wooden wheel?
A. I cannot pass an opinion on this
matter because I have no records of
actual tests made on disc steel wheels.
Most Of the new wheels are bought be-
cause OF their appearance.
@. NV car Is ftted with an Auto
Lite generator, which does not seem
to generate enough current. The
ammeter hand shows five amperes.
and II used to show ten amperes. ]
know there Is something wrong with
the generator because the battery is
low most of the time and | do little
night work. How do you adjust the
generator?
A. The trouble may be caused by
dirty brushes. dirty commutator. q
shifting OF the third brush. poor con-
nection or worn generator bearings.
I would clean the commutator. dress
the brushes and see that they do not
arc and then see IL the condition
| changes. II not 1 would shift the
third brush by means Of which the
output Is regulated. Read your In
struction book, and II you do not
| know much about electrical appar-
atus I would advise you to take the
car to the service station.
