from low to high gear?
When the high gear is thrown in be-
fore there is a proper speed relation
between the engine and the car there
is likely to be a jerk. Practice in shift
ing will remove this action. Speed the
car up on low until it gets running at
eight to ten miles an hour and then let
in the high before the car slows down.
What is the best way to tighten crank
bearings while the motor is in the
chassis7
Having removed the oil In the reser-
voir, take off the lower part of the
crank case or the bottom plate, as the
case may be. Then turn the crank
shaft until the crank throws are as
nearly horizontal as possible, so as to
make it easy to work on them. Most
motors are set up with thin shims be-
tween the bearing caps and the rod
ends. Having determined which of the
bearings are loose, take off the caps OF
these and remove one thin sheet Of the
SHIN material. This is usually a lami-
mated material, and only one thickness
should be taken off at a time. Then
replace the cap, first making sure that
the bearing is smooth and there is no
scoring due to lack OF fabrication.
Then tighten up the cap bolts as much
as possible with an ordinary wrench.
Rock the shaft sharply back and forth
to determine If the bearing is tight
enough. Do not forget to replace the
apttnr ntpo In thu consolidated nI1tc IF
on turning the shaft it appears to be
unduly stiff the bearings may be too
tightly set up. 1t can readily be de-
termined whether this Is the case, for
while there should be no looseness in
the bearings they should not be so
tight that it is almost impossible to
turn the shaft by hand.
Can you tell me the cause of a slight
grinding noise in the transmission Of
my carr 1t is most noticeable in first
and second speeds. 10 it caused by
wear on bearings?
The grinding noise is probably due
to wear in the gears and not to any
bearing wear. If your clutch has
been In the habit Of sticking and not
releasing completely, due to its being
slightly out of order, the gears have
been spinning when the shifts were
made, with the result that the gear
teeth are badly buried and worn. Moth
ing will make a more unpleasant grind
ing noise than old gears under load.
The fact that you do not notice this
noise so much in high Is an indication

is no remedy except replacement for
worn gears.
is there any good method Of telling
that each bearing has the same amount
of friction7
There is no way of determining that
each bearing has exactly the same
degree Of tightness. Experience alone
can dictate the adjustment. While
holding the hand on the bearing have
some one rock the shaft back and
forth. Any looseness can be detected
by this method.
When my car has been run for a
time IL will not come back into high
speed. What 10 The cause7
The trouble you speak Of is due to
slippage Of the clutch when in second
speed. To remedy this condition re-
move the gearset case cover some
times called the transmission cover.
The clutch fingers will then become
visible. These fingers, three in num-
Der, are locked with cotter pins. Re-
move one Of the cOtter pins and turn
the set screw one-half turn. Do the
same with the other two fingers. being
sure that the screws are turned the
same distance as the first one. Then
replace the cotter pins.
10 there anything which can be put
on a cylinder head gasket to prevent
compression from escaping or is a new
sasket required every time the cylinder
head 10 removed2
1t Is customary to use q new gasket
every time the head is removed. but If
the old I'M is in fairly good condition a
coating Of shellac will be helpful. Do
not use too much shellac, so that the
excess will be squeezed into the jacket
space.
Can you tell me an easy way to start
a car in winter?
The best way is to shut of the gaso-
line at the outlet Of the tank and let
the engine run until it sucks out all the
gasoline from the carburetor and sup
ply pipe. When you wish to start it
again simply open up the valve where
the gasoline was shut Off and operate
the starter as in n ordinary case.
Take the best car made. with all
kinds Of starting equipment, and let
1t run a few miles In zero weather.
then let 1t stand in the same atmos-
phere for a few hours without protec-
ton and the carburetor will freeze. 1t
only requires a spicule of ice one-ff-
tieth inch thick to cause the freezing.
Moisture accumulates inside the car

Of a window pane, and this Is what
freezes. 1t Is not water In the gas0-
