The fabrication of the automOh;,.
engine Is simple, and there is no az

OF its principles. On the average +vr.
there is space provided in the hotto,

Plentiful Supply Assured.
Inc troughs beneath the connecting
rods are arranged so that the oil over,

level; this method of pumping more oil

ply. The lower end of the connectinc
ROD is furnished with a small scoon or
other device for picking up the RIGHT
amount OF oil and splashing it around
INSIDE the engine. This action also
creates fog of oil, which deposits
film OF the lubricant upon parts which
would not be reached by the direct
splash.
Practically all Of the working parts
OF the engine which require fabrication
are located under the crank case or in
passages which open into it, and prac-
tlcally all engine fabrication is taken
care OF by this system. 1t can be re-
NED upon to give good results, provided
OIL IS kept in the case and the latter
is cleaned out at regular intervals n
order to maintain a proper level in the
stump it is necessary to add oil fro
quently, and at the end of each 100o
miles all oil should be drained out.
Wash With Kerosene
The crank should then be washed out
,horoughly with kerosene and new oil
be put IN. This renewal is necessary
Tor these reasons: Part of The gasolene
taken INTO the combustion chamber is
forced past the piston ring on the COM
preston stroke in the form of vapor.
When this reaches the crank case il is
recondensed into gasolene and mixes
with the oil, thinning it finally to
point where it has little lubricatlng
value. II allowed to continue for any
length OF time the engine would be
running with gasolene as its lubricant.
Also there is some wear OF the parts.
which means the grinding off Of fine
particles of the metal TO mix the oil
and be fed back into the bearings and
make them wear more rapidly Hard
carbon forms on the inside Of the piston
mead and drops into the oil, the effect
of which is obvious.
To clean the lubricating system. re-
move the plug from the bottom of the
crank case and drain out all the oil.
Clean the screen at the pump and re-
place it, and also the plug, and then
pour in about two quarts of kerosene
through the filler opening. Turn the
engine over with the selfstarter. or
under Its own power, for not more than
thirty seconds, and this will wash all
parts. Drain out the kerosene. and
with the plug open run through another
quart Of kerosene, following by pinr
Of lubricating oil to force OUT the last
of the kerosene. Then replace the plug
and refill with new oil to the proper
level.
Use Old Oil Again
1t IS not advisable to use the old
OIL again, even though it Is carefully
screened, as its lubricating qualities
nave been destroyed to a certain extent
Some persons recommend filtering the
Ola OIL and using it over in mixture
w WI. new OIL, but l cannot recommend
TINS. OIL is expensive. but it also is
expensive to replace bearings, and the
pest OIL IS none too good
Parts not taken care Of by the lubri-
eating system are the fan, which re-
qulres lew drops of oil every 100
miles, or turning down the grease cup
where one Is provided In some cases
the timing gears are located in
separate chamber and require sepa-
rate fabrication. Heavy oil is prefer
able IN this case. 1t should be in
spected every 500 miles and oil re-
plenlshed as needed. Very often the
water pump shaft will be provided
with a grease cup, which should be
allied with heavy grease and be
turned down every 100 miles. The
lgnltlon timer needs few drops OF
oil every 500 miles, and the electric
generator and starting motor require
the same attention
Attention to Steering Gear
Where overhead valves are used it
is necessary to supply few drops
of oil or turn down the grease cups
on the rocker arms every 100 miles,
unless automatic fabrication is pro-
vided. The ignition advance linkage
and throttle linkage each require 8
few drops of oil on their bearings
every 500 miles.
Although it IS not a part of the en-
CINE, the steering gear is located un-
der the hood with the engine aud
requires attention every 1000 miles.

cleaning out the crank case somr-
times is a dirty job, and calls 70
