What is the approximate saving in
current when using the two headlights
switched on as DINNERS instead Of
switched on full2
This all depends on the method OF
dimming used. If the lamps are dim
med by connecting them In series then
the current consumption is cut IN half
If the resistance In the wires Is neg
lected. and since this IS small it may
be. If two bulbs are used In the head
light, a large one In focus for country
driving and q small one out OF focus
for city driving, the saving may be
much greater, the small bulb taking
about a fourth the current Of the large
one.
am troubled with fire coming from
the exhaust cut out underneath my
car when running rapidly and shutting
off quickly, also when pulling hard. II
10 not the regular exhaust from tho en-
CINE, but a large blaze like gasoline fire
which comes clear to the ground and
spreads out several feet each way. Can
you explain it7
1t is difficult to say exactly what Is
causing this trouble without seeing the
car. However, It may be that the
valves are improperly timed or the mix
ture may not be correct. If the valves
have been reset lately it would be wise
to make certain that the timing Is cor
rect, but II they have not been reset
they probably are all right. If the
mixture is at fault 1t Is n simple mat
ter to adjust the carburetor. Possibly
there is carbon in the exhaust pipe or
1t may be that you are running with
the spark too late.
My front axle Is bent about one and
one-half inches from the spring seat
to the outer end of the axle, a dis
tance of about ten inches. How should
il be Strengthened?
This axle should be heated to a cher
~ red heat and then Strengthened. The
heat should be applied at the bend
only, and as this Is ten inches from the
king pin bushings there Is no reason
why the latter should be heated and
therefore no danger of them becoming
enlarged. In fact, 1t Is doubtful
whether they would be enlarged even
II exposed directly to the heat. 1t is
necessary to give the axle any heat
treatment after it Is Strengthened.
Does it make any difference how
many tooth are In a bevel gear in re-
lation to the gear it works in?
The relation of the number Of teeth
on the driving pinion to the number
on the large gear gives the ratio be-
tween the number Of revolutions the
motor makes as compared with the
number the wheels make when the car
is travelling or high gear. Any change
in either the pinion or bevel gear
alters the ratio.
What 10 the cause Of inner tubss bs.
eementsd or fastened to tho
casing 90 Il 10 very difficult to remove
This Is caused by ~neglecting to use
enough tire tale between tube and cas-
Ing. Whenever a tube Is placed into
a casing always sprinkle tale over the
inside Of the tire. Tale is a white
powder. which is cheap. and may be
bought at any supply store.

If only slightly worn bearings may
be adjusted by removing shims or by
fling the bearing caps. II the bear
are scored or worn out Of round
or If new bearings r put In the sur
faces must be scraped.
II the bearing surfaces are In good
and not worn out Of shape a
slight adjustment should be SUFFICIENT
to make them tight. There are usually
shims under the bearing cap,
and by removing these n by n the
looseness will disappear. Remove only
enough shims to make the bearing a
snug but not a tight at. When shims
are not used the lost motion may be
removed by placing the bearing cap in
q wise and filing down the surface. In
case too much material 10 removed 4
copper or paper SHIN or shims should
be inserted to make the cap at In
ding the fat surface Of the bearing
cap should be preserved. the file not
only being held nat against the sur
face. but the movement Of tho tool
being carefully executed.
II the bearing II scored. new or worn
out Of round 1t will need scraping.
This should be done by an experienced
man. Connecting rod bearings may be
scraped without tearing down the mo
tor. but II the main bearings require
scraping the motor must be disassem-
bled and the crank case placed upside
down with the crank shaft and ny-
wheel still IN position. The main bear.
ing caps are removed, and the crank
shaft bearing surfaces are painted with
q solution of Prussian blue. After ro-
tating the crank shaft a few times and
