Why does my clutch make a grinding
noise when II 10 pushed out in coast

You probably have a broken bali in
the thrust bearing back Of the clutch
spring. Treat the leather with meats
foot oil and then try roughing up the
matted surface Of the leather with a
small saw blade. See If the springs
under the leather are working salts
factorily. Perhaps they need tighten
ing to make them act against the I'M
der surface Of the leather. If the
leather seems too badly worn the cone
should be refaced.
Would the removal of spring leaves
improve the riding qualities of car?
If so, which leaves, and how many? !
have equipped II with shock absorbers
and keep the leaves well fabricated
without helping IT materially.
1t is not advisable TO remove any OF
the leaves from the springs. These
are designed to carry the load without
being too. stiff, and the removal OF
leaves would not only weaken the
springs unduly. but might spoil the
riding qualities. 81, &.
Can you tell me a way in which to
quiet the valves on my carr They
have Just been adjusted and the clear
ance seems 10 'be correct.
II the adjustment is correct then
thefe,is one other thing which may be
responsible for the valve noise. II the
valve guides or the valve stems. or
both, have become worn there Is a
chance for side play when they are OPP
Grating, thus causing rattle. The best
way to determine this is to take out
the valves and examine the stems for
excessive wear Then the guides which.
are pressed into the cylinder castings
can be removed and examined. You
might be able to inspect them without
removal.
My car was overheated about year
ago, after which il developed a knock.
Have had it takon up but soon after It
was as bad as before. ] would like
advice as to how ! shoul d proceed to
take the motor out of the chassis as
wisho to overhaul it myself, providing
there is no machine workto do. Should
a motor have q knoek or metallic sound
when warpaed uPy tGhhinq fifteen miles
per bopr With FIVE ipessensers, a very
little 3p, sFaas9 rave driven $500 miles
and motor 70 free from carbon. Have
always used a medium oil, winter and
suGTner. f.. AM,
II you want to TAX, TIE motor" out Of
the chassis you can prodetd as follows:
First drain all water from the cooling
system by opening the cock at the bot
tom of the radiator Their, disconnect
.the hose connections between motor
and radiator. There are two Of these.
Take off the radiator by christening
the bolts which hold it to the frame.
Disconnect the spark and throttle con
trolls from the bottom of the steering
gear. Loosen the connection between
the end of the exhaust manifold and
the pipe running to the muftier. Dis
connect the gasoline feed pipe from the
carburetor. If the car Is fitted With
electric cranking and lighting then you
will have to remove the wires from the
electric motor and generator and also
from the horn! Be sure to tag each
wire so you Will know where to replace
it.
The next step is to diSengage the en-
CINE unit from the drive shaft. There
is a means of doing this back Of the
clutch. Take out the bolts that make
the connection. Finally remove the
holding bolts which fasten the real
arms of the engine to the frame mem
bers and then disconnect the front sup
port, and by the use Of an overhead
crane or block and pulley arrangement
the engine should come out of the chas
sis after moving it TO clear the drive
shafting at the back Of the clutch.
A motor should not have knock al
any time, Under the conditions yoI
mention the knock. Is probably cithel
a carbon ignition or gas knock. Yot
may be giving the engine too muci
fuel on ascending grades. or yon ma!
open your throttle too quickly, Re
tard the spark somewhat on hills ant
see II the knock fsnot eliminated.

Would il pay me to set my oarbu
rotor higher, thus lessenine the length
of the manifold, and equip my ca
with vacuum feed system2 The saso
line tank being under the front seat IN
carburetor cannot be elevated Withou
vacuum system.
Anything that VIII aid in the short
ening Of the intake manifold Is a.
4 advantage, and you could probabl.
| get good results with vacuum tani
The less the condensation in the mani
fold the better. and shorter manifold
would give you more power. Besides
It would make the carburetermofe aS

How often Is II necessary 70 chang
he oil in an engine crank case?
Some people change It about ever
thousand miles, and It seems adyisabl
| TO do 1t that often after removing Ga
oil through the plugs at the bottom
