axle drive gear to see if it is properly
adjusted?

battery depend on the size and number
Of plates?
6. What are small springs around
rim of cone clutch for?

lubricants and tell where used?
s. What evil results from a too
a driver prevent too rich q mixture?
g.. Give three things that may cor
rect over-heating of motor?
10. What is the least number of
gears o can have in a differential and
| still operate properly?
II. In a differential of the bevel
gear type which way are the differen-
tial pinions revolving in the spider
when the car is turning to the left?
IL. What prevents shifting of two
gears at one time in the selective
type?
13. What argument would you make

IA. Where is the auxiliary air valve

parts that will wear on a generator
w. H., Jr.
1. insufficient oiling. high and
thrust. bearing too tight, excessive
crankshaft vibration.
! 2. Get underneath with oil pan re-
moved and use a jack operated slowly
to lift crankshaft through play de-
veloped.
3. 1 do not know of any system
| that does not employ a cut-out or cir
cult breaker. or similar means to dis
connect the battery from the generator
when the engine is idle.
4. l would put a thickness guage
between ring gear and pinion and see
if the backlash is correct. 1t should
be from .OO3 to .OO5 inch. If you
mean the driving pinion. I would check
not only the backlash but also the
position of the pinion with respect to
the ring gear. The heel of the pinion
should as near as possible be on a
level with the edge of the ring gear.
that is, the pinion should not stick out
beyond the ring gear very much mot
over 1-16 inch). i
5. Area of plates and number OF
plates is correct.
6. To effect easy management OF
the leather thus preventing grabbing.

different body may be used for lubri-
eating purposes on the car. Grease
may be used for heavy loads such as
exist in spring shackle bolts. wheel
bearings or for places where oil is
likely to run out quickly. Graphite may
be used where grease is used. or 1t
may be mixed with grease and used
whenever a non-lubricant is needed.
s. Using the choke too much is
likely to score the cylinders because
the gas cuts the oils around the PTS
tons. Where adjustment is provided
the driver may cut down the amount
of gasoline fed. Where a non-adjust-
able carburetor is supplied the driver
can do nothing.
8. This will be taken up in an arti-
Gle of mine on overheating scheduled
for publication within the next fort
night.
10. We can get along without a diff
ferential on some cars. Where a diff
ferential is used We can use a two
pinion spider, two axle shaft gears
making four and the ring gear and pin
ion making six.
II. Clockwise on their axis.
II. There are two shifter forks and
only one can be engaged by the end of
the gearshhift lever.
10. 1t is cheaper to have brakes re-
paired than it is to have doctor bills.
a wrecked car or perhaps a suit in
court for damages. due to collision,
property damage or liability.
II. Modern carburetors do not use
auxiliary air valves. Some have them.
They are part of the instrument and
begin to feed air after the primary air
intake has reached its capacity.
Is. A worn valve stem permits air
to leak into the combustion chamber,
may cause the valve to slap or mis-
firing because of air leakage.
IS. Loss of compression, perhaps
misfiring and loss of power.
II. There is no such thing as the
one most important part. All main
units. (~engine, clutch, transmission and
axles) are equally important.
IS. The bearings, brushes and com
mutator.
