answers to Last Weeks Questions.

Answers 10 Last weeks questions.
IA grinding noise in the rear
axle when the car is in motion in
dictates too deeply meshed gears
or lack of lubricant at these parts.
Gears out of alignment as the re-
suit of a wreck will also create q
grinding sound.
1.-THE radiator of a thermo-sy-
phOn cooling system usually diff
fers from that of the forced cir
culation system in the construction
of the small tubes or water pas
sages Of the radiators. That of the
thermo-syphon system is usually
constructed with passages of larger
volume than that of the forced cir
culation system.
3.-Electric light troubles can be
told by the dash indicator as fol-
lows: If the indicator reads dis
charge" with lights turned off and
motor not in operation, the usual
cause is a short circuit at some
point ia wiring, such as barred wire
in contact with Trace or other met
al part of the car; when the indi-
Gator does not show "charge" with
engine speeded up, but reads dis
charge" when the engine is ut
rest and the lights are turned on,
the generator is at fault and is not
producing sufficient current. When
the indicator does not show dis
charge" with lights turned on and
engine not running, and does not
indicate "charge" when the en-
CINE is accelerated there is an open
circuit, such as a broken wire, a
loose connection, loose or corrod-
ed battery terminals or a poor gen.
orator connection.
A unit electric system Is a
system which performs the func-
tons of starting, lighting, charging
and igniting without one motor
generator. 1t has a timing and
current distributing device for ig-
hitting the gas charge in the cyl
inders. AS a motor this unit cranks
the engine: with the engine in OPP
GRAFTON it is driven as a generator
the storage battery sup
plying current for the lights and
by means of a timer and distrib-
utor igniting the gas charge in the
cylinders.
5.-Brakes which continue to slip |
when applied after being frightened
to remedy the condition have eth |
err worn fabric, oil on the brak-
Ing surface or the heads of the riv-
cts, which hold the braking fab
rio to the brake band, are flush |
with the surface of the fabric and |
prevent 1t from gripping suffl- |
GENTLY.
6.-Some common causes Of rat
ties beneath the car are wear in
he radius or torque rods, loose
oraking bands or rods, worn con-
nection in gear shift levers or rods,
Or play at the spring shackles.
End thrust on a bearing
means the force exerted parallel
o the shaft on which the bear
ng is carried.
S.-A knocking or clicking sound
n the universal joint is caused by
wear in the connecting pins on
which the two members of the
universal oscillate or move,
9.-The cause of a heated plan
,tary gear case is lack of oil be-
ween bearing surfaces of the
transmission or by either binding
n slipping brake bands.
10.-Gear ratio of the rear axle
AN be ascertained by dividing the
lumber of teeth in the large ring
rear of the differential by the
lumber of teeth of its pinion.

reading on the am
meter of an electric system?

he engine is all right?
9.-Name six causes fir expl-
ions in the inlet pipe or carbu-
eter.

ermined?
