I cumulates on the oil strainer in the
lower crankcase, and may retard cir
culation of the oil, in which case seri-
Gus damage TO the engine is almost
| certain to follow. This sediment may
collect in the oil pipes and passages,
thus preventing adequate flow of oil
TO the various bearings.
Road Dust
Some dust is always present in the
air, and where dusty roads are en-
countered the amount is, of course,
greatly increased. All engines are
equipped with crankcase vents or
breathers through which dust-laden air
is drawn into the crankcase and mix
ed with the oil. Where vehicles move
slowly, dust going into the engine be-
comes a very serious factor affecting
fabrication and if carried to the bear
ings, will cause excessive wear. Dust
also assists in the formation and de-
post of sediment around the oil pump
strainer.
water is one of the products of
combustion in every gas engine. This
is frequently evident from steam and
drops of water emerging from the end

when operated in cold climates.
"On the power stroke, a portion of
the water vapor may be forced past
the piston into the crankcase where il
will condense and mix with the oil.
Metallic Particles
Even when correctly fabricated it
is impossible to entirely eliminate
wear of the bearing surfaces. There
fore minute particles of iron, steel,
babbitt and bronze, the result of veal
become mixed with the oil.
while the heavier metallic parti-
cles will settle to the bottom of the
oil, the lighter or smaller ones will be
carried into the bearings, causing
rapid wear. They also mix with the
] carbon and road dust to form sediment
Necessity For Draining Crankcase
~"Conceding that the oil in the en-
CINE has it's ~lubricating value impair
ed by the effects of engine operation
it is apparent that to overcome this
the old old must be drained from the
crankcase at frequent intervals n a
supply of fresh oil put in.
Proper Method of Draining
when the mileage covered or the
condition of the oil in the crankcase
indicates the necessity for fresh oil,
J the old oil should be drained. This
should be done Immediately after the
engine has been running for sometime
and the oil is warm. The oil being
warm, less of it will adhere to the
inner surface of the ~crankcase and the
solid matter in suspension will have
less time to settle and remain in the
dip troughs and stump.
THE drain plug should be replaced
and the proper quantity of some flush
ing agent poured into the ~crankcase.
The engine should hen be run under
it's OWL power (for from n to two
minutes) in order to carry the flushing
J agent to all surfaces inside the crank
tease where sediment is liable to col
lect and to all bearing surfaces with
sufficient force to wash and carry
away any foreign substances. Old oil
and sediment will thus be dislodged
from the oil, pipes, passages and dip
troughs and carried down to the low
e rsump, to be drained when the plug
is again removed. Whenever the de.
sign of the engine permits, the ssfeen
or strainer through which the oil pass
es should be removed cleaned and re,
placed.
During this operation the old oil
film will be washed from the bearing
surfaces and unless the flushing agent
possesses sufficient lu%bricating quail
ties within itself to overcome this de.
ficiency, serious damage to the bear,
ings may result. Also, a certain
amount of the flushing agent will re.
main in the engine after draining and
will hn fniynA with trash lnhriPDtinp
oil. The lubricating value of the fresh
oil will be reduced if an impropre
flushing agent is uesd.
kerosene as a flushing agent is
open to both these objections and
should not be used for this purpose,
