To tackle q valve replacement singlehanded
when you have not a valve lifting deyics Is
not anything TO look forward to. There Is .
way Of getting around the difficulty. Simply
interpose a piece OF packing. almost anything
will do, between the valve cap and the valve
head; reAx the valve cap sod the packing viii
prevent the valve rising To Hft the spring
and take out the cottsr is not hard now.
'-' Spring Clips.
The snail clips that are frequently mounted
on the outer ends Of the Leaves of seIni-eIli7-
teal springs must always be kept drawn up
tightly. The function Of these clips is to pre-
vent the leaves from getting out Of alignment
and they also act even as shock absorbers by
bringing the outer leaves into action on the
rebound, while they likewise increase the frie-
ton between the leaves.
Rim RustIng.
When a rim has had some of the paint
Knocked off, take the precaution Of applying
some graphite paint at once. not only for the
looks sake but to prevent the formation Of rust.
Corroded Terminals.
Battery terminals that have become eoroded.
may be cleaned best by a strong solution Of
washing soda. After they have been dried.
a light coating Of yaseline will serve to protect
them against . return Of the trouble.
In Realizing 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 later may be. But
If 50 much OF the water has been lost that the
tops Of the cylinders are uncovered, the engine
should be allowed to cool of before the water
system Is filed The reason Is obvious IL cold
water is poured directly on the hot cylinders,
where they are exposed, there is danger OF
cracking them, owing to the contraction due 10
the npid cooling effect Of the water.
Keep Planetary Gears Tight.
1t Is a wise precaution to occasionally go
over the bolts which secure the several sections
Of q planetary transmission. TO see that no
lOoseaess has developed. While the loss Of a
bolt or 30 might not be enough to allow the
gear TO separate entirely. there is danger that
it might weaken the fastenings 50 to permit
the gears to work slightly out Of mesh, or
that the remaining bots might be sheared on
~ . result Of being overloaded.
Lubricating Pump Spindle.
In repackfng the gland Of q water circulating
pump, use ulenty of graphite with the packing.
The spindle is seldom Adequately lubriczted
and the graphite will go a long way toward
making up for this Incidentally the use OF
glycerine in the cooling water as an anti
ton Of the pump spindle.
Replacing spark Plugs.
Two things are TO be avoided iR replacing
spark plugs one being too tight an adjustment
in a hot cylinder. which makes it almost i'm
possible TO remove the plug afterward and the
other is the breaking Of the porcelain insulation
In plugs Of that type through contact with the
wrench. Socket wrencheA IL made too narrow
in the neck will often cause fracture Of the
insulstor unless held perfectly in line.
Determining Polarity.
About the simplest way Of determining which
Is the negative and which the positive wire Of
the battery is by dissol7ing a few grains OF
iodide Of potassium q bit Of blotting paper
moistened with water. When the paper 50
treated is touched with the two wires, the
positive wire will form q black stain. Iodide
Of potassium may be purchased in any drug
shop.
Separating Gear Case Parts.
When separating sections Of gear boxes or
crank esses. it will sometimes be found thst
the parts stick together after the bolts have
been removed. Care should be taken in sep
arating them. especially If the parts are OF
aluminium. Driving a chisel or scrow-driver
between the two sections may make q nick,
which will spoil their, oiltightnss, or may
raise 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 q number Of places. after the
stuck parts have been tapped all around with
a light hammer. win usually separate them with
out damage
Loose Cheek Nuts.
Loose check nuts on the rods in the braking
system may become the canse Of serious mis-
hap. II they are not remedied in time. When
the check is removed from the turn-buckle or
other adjustment. the tendency Of the vibration
il 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 eonsidsrstion
