Motor Department - The other
night when / attempted TO start the
engine in ny car there was a very
loud explosion in the back of the
car. Ever since then I notice that
the engine, or, 20 be more correct.
the exhaust, makes more noise than
IL did before. 1t sounds almost as
If "out-out" were partly open. What
do you think is wrong? F. L.
The explosion you heard is a com
mon occurrence on some cars, and
IS caused by accumulated gas in the
exhaust pipe and muffler becoming
ignited. Evidently the explosion
loosened the muffer. so that the
noise you hear IS the leaking OF ex-
haust gases. The muffier should be
removed and reassembled in order
TO make a satisfactory repair job.
Motor Departmental a constant
reader Of your paper and the motor
column, I beg for your suggestion on
my theory. l have a 1914 four
cylinder Cadillac. 5-passenger tour
ing car, which is o. K. as can be
expected and am overhauling
same. as I make my own repairs.
I am asking for information which
is somewhat too deep for me. While
/ have it down I though now would
be "A good time. How can I install
double ignition. that is, four more
plugs with the four I now have.
am using the Delco system which
came on the car, 6-volt battery
timer and distributor, starting on
dry cells, then switch over on stor-
age battery. H NJ.
You would have to eliminate the
Delco generator in order to install
a magnetic. Extra spark plugs could
be installed In the other valve caps.
It would be quite an expensive
change and hardly seems advisable.
However. you can better judge the
cost by consulting a Cadillac dealer.
Motor Observation-Disclosures tell me
how to adjust ring gear i'm pinion
on my car to stop the growl. Car
las been run about $4,000 miles. /
Toe gears are apparently in good
tond ition-no Clipped or broken |
teeth or perceptble wear. Any in
forma, % will be appreciated.
A. L.
Adjust pinion so that 1t lines up
with edge of ring gear, then move
ring gear over till it meshes closely |
with pinion and runs quietly. You
viii find the adjustments inside by
removing cover. When properly ad- I
justed a piece of newspaper may be /
run through between the teeth with
out being chewed to pieces.
Motor Experimentation the small /
brass tube which carries the oil /
from the transmission to the front |
end of crank case on a Ford engine /
become clogged? If tube becomes /
stopped up, what eqect will it have /
and how could 1t be known? +. c.
These tubes became clOgged on |
rare occasions and the engine runs |
dry, finally stopping with a seized |
piston or bearing. The upper fly /
wheel housing must be removed |
and a wire run through the tube.
Motor Department have a |
Model 60 Overland touring car. and |
would like TO know how TO take the /.
apart. The crown gear
is Clipped and 1 would like TO re-
place it with a new one. ANY in
formation you may give will be ap-
preciated. OWNER.
Take off the rear wheels and axle /.
housing cover. Loosen the two large /
nuts, one on each side of the diffen- /
tial on the axle shafts. Pull the /
axle shafts out and then by un-
screwing the four bolts that hold /
the caps on the differential hous-
ing, the dinerential may be lifted
out.
