will you please toll mo how TO line
- the front wheels Of . car?
In lining up the front wheels the first
Ching IL to make sure that the wheel
hearings are properly adjusted. They
should be Just tight enough so that
1Aero Is no side play in the wheels; but,
- the other hand, they should not be
- tight that the wheels bind and do
not turn freely. This done, take long
sick or rod that will reach from the
inner edge Of one rim across to the In
,n< edge Of the other. Then measure
the distance between the rim edges
AprizOntally back Of the center Of the
wheel Mark this distance on the stick
;snd then try 1t on the rims horizontally
In front Of the wheel centers. The
front distance should be one-fourth
fnch to three-eighths inch less than the
distance across the backs Of the hubs
II you find these distances are not cor
rect you can get the proper adjustment
by taking up or letting out on the
steering cross rod, which parallels the
axle and runs across just back Of IT..
First loosen the lock nut at one Of the
ends, then take out the pin that goes
through the steering arm and yoke and
screw the yoke out or in, as the case
requires. Then check the wheel align
ment again and tighten the lock nut.
What 10 the object Of clutch brake?
a clutch brake is "a device to check
the momentum of the clutch while
changing speeds. Usually when the
clutch Is thrown out or disengaged
It tends to spin for some time, due to
the momentum it received from the
engine. The clutch brake rubs on the
clutch or clutch shaft in such man.
ner as to slow it up so as to make
quiet gear shifting without having to
wait for the gears intended to be
meshed to assume approximately the
Aame speed.
When taking down my car ! put the
eyiinders into solution Of caustio soda
- remove the old paint and have found
~&5sax the solution acts as an excellent
carbon remover. Il scales the carbon
right off and leaves tho surface cleaner
than after scraping. Could you tell me
~ it would harm tho motor to inject
St into the cylinders and let It stand
Tor q day or two, then start up The
motor to blow the carbon out through
-sho exhaust? If some Of It went by the
s4istons would Il have any effect on ths
fabrication? Does Il attack iron?
Your suggestion regarding removal
~ carbon is very interesting, and It
should cause no difficulty provided

havoc may result.

1t Is dangerous to use this solution
when the crank case is aluminium, as
some Of the liquid might leak down

IN using an alcohol and water mix

when first mixed, the percentage of
alcohol remaining in the solution?

What is the difference between direct
current and alternating current?
In direct current the electrical cir.

alternating current the electrical cir
