COrrOded Terminals.
Battery terminals that have become
| corroded, may be cleaned best by a
strong solution Of washing soda. Aft
! er they have been dried, light coat
| ing of vaseline will serve to protect
! them against a return of the trouble.
In RefIIIinE Water system.
In the main there is no danger in
pouring cold water into the cooling
system OF the engine, no matter how
| hot the latter may be- But II so
much OF the water has been lost that
| the tops of the cylinders are uncov-
cred, the engine should be allowed to
cool of before the water system Is
filled. The reason Is obvious; II cold
water IS poured directly on the hot
cylinders, where they are exposed,
there is danger Of cracking them, oW-
ing to the contraction due to the rap
id cooling effect Of the water.
Keep Planetary Gears Tight.
1t is 4 wise precaution to occasion
ally 90 over the bolts which secure
the several sections Of planetary
transmission, to see that no looseness
has developed. While the loss Of a
bolt or so might not be enough to al
low the gear to separate entirely,
there is danger that il might weaken
the fastenings so as to permit the
gears to work slightly out Of mesh, or
that the remaining bolts might be
sheared off as result OF being over
loaded
LubricatIng Pump Spindle.
In repacking the gland OF a water
circulating pump. use plenty OF
graphite with the packing. The spin
die is seldom adequately fabricated
and the graphite will go long way
toward making up for this. Incident
ally the use Of glycerine in the cool
ing water as an anti-freeze precau-
tion, seems to assist in the fabrication
of the pump spindle.
Replacing spark Plugs.
Two things are to be avoided in re-
placing spark plugs. one being too
tight an adjustment in a hot cylinder,
which makes it almost impossible to
remove the plug afterward and the
other Is the breaking Of the porcelain
ensulation in plugs Of that type,
through contact with the wrench.
Socket wrenches, II made too narrow
in the neck will often cause fracture
OF the insulator unless held per-
fectly In line.
Determining Polarity.
About the simplest way OF deter
mining which is the negative and
which the positive wire Of the bat
terry is by dissolving a few grains Of
iodide OF potassium on a bit OF blot
ting paper mOistened with water.
When the paper so treated is touched
will form a black stain Iodide OF
potassium may be purchased in any
drug shop.
Separating Gear Case Parts.
When separating sections Of gear
boxes or crank cases. it Will some
times be found that the parts stick to-
gether after the bolts have been re-
moved Care should be taken in sep
arating them, especially IL the parts
are OF aluminium. Driving ehisel or
screw driver between the two sec
lions may make a nick. which will
spoil their oil-tightness. or may raise
a burr, which will prevent the parts
from coming together properly. The
application of too great force may
cause the parts to spring. Gently
prying at number Of places, after
the stuck parts have been tapped all
around with light hammer will usu-
ally separate themSwithout damage.
Loose Check Nuts.
Loose check nuts on the rods in
the braking system may become the
cause OF a serious mishap, IL they are
not remedied in time. When the
buckle or other adjustment. the ten
dency Of the vibration is TO loosen
the adjustment OF the bands AS this
may occur when the car is running.
the chance Of having the brakes fail
through slack adjustment, IS worth
taking into consideration.
OWNERS SERVICE DEPARTMENT..
The crank case relief pipe OF my
Harley-Davidson motorcycle, does not
spray any oil upon the chain drive.
What is the cause OF this condition?
". Hitchon.
It does not matter that no oil IS
sprayed on the chain as oil coming
through this relief pipe is simply eX-
cess from the crank case. When
there is no excess in the crank case
the chain gets none and you will have
to oil the chain in the usual way.
have been using boiled water in
my storage battery and it seems to
me that I detect some deterioration in
the action of the battery. Could this
be caused by the water I am using,
or is It due to some other eause?-
Boiled water is not satisfactory for
use in refilling the storage battery.
Distilled water, that is water result
ing from turning water into steam
and then condensing it again, must |
be used. Soft water, that is perfectly
clean rain water or water made by |
melting absolutely clean snow. may |
be used.
Can recharge or otherwise revive |
a dry cell battery that has gone dead2 /
a friend tells me that by using some /
sort OF acid the battery may be made /
as good as new.-Jess-
Your friend is wrong. No acid will /
revive q dead battery, except for |
little brief activity, which is not l
worth gaining, except rs an emery /
ency measure. Even vinegar will /
galvanize a dead battery into brief 4
action for emergency purposes.
I am hang a lot OF trouble with /
overheatiur Of the cooling water in /
my 1915 roadster. What is the cause? /
p. J. S.
Your question is too vague for pre-
else answer. as there are many causes
Tor overheating and unless 1 know
some OF the attendent symptoms. I
cannot hope to diagnose the trouble.
Corban in the cylinders viii produce
)verheating, so will incorrect mix
-ure, an obstruction in the radiator.
Incorrect timing of ignition or valves.
First try giving the engine as lean
mixture as it will stand without mis-
firing. Test the spark. X the en-
CINE has a tendency to backfirins,
with loss Of power, you may be sure
hat carbon is the trouble. Finally |
zee that the fan belt is tight enough
10 operate this part at full speed. II
rour trouble continues, write me more
detailing symptoms as
we'll as effects.
How many storage batteries can
.harge from a lighting circuit such as
S used in the shop? How is it done?
-Edmonds.
In the first place the light circuit
urrent must be direct current other
wise a rectifier will have to De placed
n the line as only direct current can
