Is IT possible for trouble to develop
l inside the axle but having nothing
to do with the gears? The reason I
ask this is because there is a peculiar
noise coming from the rear axle and
I looked at the gears through the
cover plate and they are all right.
What else is there in there that could
cause an awful noise like broken
gears slipping around3-H. L. Poison.
Appears to me as though one Of the
axle SHIFTS is at fault and the real
trouble due TO a broken spine II thar
construction is used or a worn end
II the shaft has a squared connec-
ton with the inner gear.
I have not been accepted for ser
vice and since I am a good mechanic
on high speed engines, would like
to know where I can connect with
one OF the race drivers who Is look
ing for a man like me. ] have had
quite bit Of experience and can work
out some good ideas have I am
good lathe man and understand fine
work.-T. Williams.
Send your request to the American
Automobile association, sol Fifth av-

trolls racing and Is in constant touch
with the drivers.
How long should It take to grind in
a set OF valves on a six2 Is 1t usual
to have TO replace valves after 5000
miles use2 How much do tungsten
valves cost and do you think they
viii do what Is claimed for them. that
is, last longer than iron ones and
not need so much grinding?-K- B.
Cadman.
/. Depends on the condition Of the
valves and seats and the aggressive
ness Of the workmen. It may require
five hours and again ten.
2. II Is not usual. N the engine has
been properly cooled. Run without
water many times and the valve heads
viii warp. Poor metal IN the valve
heads is the cause OF much warpinE
8. They cost about four times more
than the iron ones. They can with
stand more heat and wear and do not
need grinding so often
wonder Il YOU have formed any
opinion about the steam cars on the
market now. If they DO everything
that is claimed they certainly have
got It all over the gas car. but surely
there would not be only two steamers
and hundreds OF makes Of gas cars.
II there was not something up their
SLEEVE Bruins.
The steam car OF today is a highly
developed type and exhibits few
weaknesses, but please rememb Der
that this does not mean that there are
no troubles connected with the run
ming OF a steamer. There are. but
little is said about them You should
not question the reliability Of the gas
car nor its return in service per dol
lar expended. because Il has shown
what IL can do in actual service. The
steamer may be able TO perform a
bit nicer than most gas cars (run
slower, climb hills better. etc.l. but I
should say that performance charac-
teristic alone do not determine the
value OF a car.
VIII special piston rings stop leak
ing OF oil in most cases2 How many
do you have TO put on a piston and
win K help 70 put them on II the CYL
inder Is worn out OF shape?-V. A.
Waldeck
II the cylinder IS worn oval the
rings viii help little. There are
some very good special rings on the
market, but I should make sure that
the oil pumping IS due to poor rings.
One on each piston viii do, II the
condition Is not very serious.
