a moment. as this may remove a small
obstruction in the strainer or oil
pipes. II this does not remedy the
trouble. the operator should start sYs-
tematically to examine the various
points where trouble may occur. II
gear type pump is found to leak
within, the trouble may usually be
remedied by reducing the thickness
Of the pump housing by rubbing II on
emery cloth. The thickness of the
housing should be reduced to a point
where the pump can just be turned
freely with a screwdriver.

be remedied by locating and remov-
ing the cause.
INDICATION OF FAILURE
In constant level splash systems
in, which a sight feed gauge Is
provided on the dash to show the
flow OF oil, failure of the oiling
system is usually Indicated by a
diminution or cessation in the flow
OF oil through the gauge. The
burning out or overheating Of one
of the main bearings OF an engine
with simple splash oiling system
may be due to the oil collecting
wells that direct the lubricant to
the bearings becoming filled with
dirt or gummed oil. Where an ad-
justment is provided to vary the
oil level. over or under fabrication
may be due to an improper adjust
ment of the overflow pipe. - &c
There are a few cars which have
oiling systems differing materially
from the usual types. One OF these
is the Ford. In the Ford engine
the flywheel dips into the oil con-
tanned in the bottom OF the fly
wheel housing. When the engine
is running the flywheel picks up oil
and. due to centrifugal force, throw,
Il into a pipe which conducts II e
the front Of the crankcase. There
are troughs under each cylinder and
| the oil flows back from one trough
to another until IL eventually fndi
it's way into the flywheel housing
again. The connecting rods dill
| into the oil in the troughs ant
throw 1t to all parts of the engine
There are two cocks on the lowe
! part OF the flywheel housing I,
show the oil level. The crankcas
should be filled until the oil run
out Of the upper cock. The oil
level should never be allowed TO fal
below the lower cock. II the engin
shows signs Of insufficient lubrica
ton, then the oil pipe for conduct
| ing oil to the front OF the crank
case may be clogged up. As there
no sight feed oil gauge on the Fore
| engine, there is no warning OF sucl
a stoppage until the engine start
TO overhead or show other signs o
| insufficient fabrication.

Gated by overheating and noisy opera
