g. WA you answer INC fOI10WIng
question? ! have C---) stor-
nge battery installed In my car. [ wish
To Know II there is danger Of this bat
l'Iy lIocHlng, and, II sO at what tenn
pefature? | have been informed thar
a battery fully charged will not freeze
" thls be true, then at what point Of
dlschalge Is there danger Of frccz
ing? w q n
a. The freezing points of a storage
DaitcIy are rs follows:
specific gravity l.I2O (dischargcd)
at 20 degrees above zero.
specific gravity I.1GO uhrcc- -fourths
uischhrgrd), at zero.
Spcciiic gravity 1910 (onc-half dis
chargch), AZ 20 degrees below zero.
SPECIFIC gravity 1880 Zone fourth
dlschargcd), at 90 degrees below zero.
From the above IL would seem that
me danger from freezing i small, vet
~c Jars of many batteries arr, ruined
D~aiisc of freezing. In the winter,
the engine Is liable To start hard. and
many people make the mistake of
using the current from the battery TO
drive the startcr-motor for IA long
lime, sometimes five and SIX minutes
at stretch. and 80 very quickly dis
chargc their battery. If owners will
prime their engines with raw gasoline
before using the starter, there viii be
practically no danger IN respect to the
battery freezing.
9. ] am working on the differen-
tial of II 1914 Ford car that had a
bumming in it, The thrust plates
yere almost worn out, so | put a new
fsct in and now II has Il louder hum
ming than before. Can you suggest
something eles to do? A. l.. ii.
a. II Is quite likely that the ball
Al La A. "a
thrust bearing are also worn, and so
allow the pinion 10 he pushed toward
thc front of the car. Before YOU re-
placed The thrust washers on the axle
shafts the drive gear was pushed to
the left, probably the same amount
the pinion Is pushed forward, and so
while the pinion and gear not mesh
ing deep enough, causing the hum.
their setting aS regards pitch relation
was little changed. the large ends of
the teeth OF the drive year mcshing
win the large ends of the teeth of the
pinion. Now that YOU have put in the
new washers, the drive gear has been
held in position more 10 the right,
but the piniOn is sim forward. ana ~
the large ends of the drive gear teeth
arc meshing away from the ends oi
-thc pintOn, or where the teeth and
spaces between the teeth are slightly
" the gear j. badly worn. replacing
the thrust washers or bearings. will
not eliminate the hum, but rather
tend To increase il.
q. NV 1911 car will not pull good
on low or intermediate gear Began
TO fail last Saturday. man said the
rings were worn out. w. Il.
\. You give me little information
so j Will give n list of the things which
might cause an engine 10 lose power.
First OF all loss of compression, due
possibly 10 leakage past the rings.
which Will be often indicated by
Kissing, sort of steam engine exhaust
sound when the car is laboring on
hil; valves leaking; or leakage past
the plugs or compression cocks. Bad
mixture viii mean loss of power. and
rs your troubles dCyclopcs with the
cold weather, perhaps here is the
source of the trouble. II the lack of
power il only noticed when YOU first
start out. the cold Is To blame. The
mixture can stand, hCiug richer in the
winter than In the summer
q. In my 1915 four-cylinder g
car, carbon is constantly causing the
motor to knock. DO you think (XxX)
carbon remover safe to use, causing
no damage to the cylinders or is
there any method OF removing the
carbon without damage to the engine,
other than taking it apart. What is
the advantage of mixing Elycerine
with alcohol in the radiator

express an opinion either for or
or against special devices or COM
pounds. About the hest way To have
