3 to 5 drops of medium engine oil every 50 hours.
Every 50 hours of operation,
the oiler
on the side of
the distributor
base should have 3 to 5 drops of me-
dium engine oil added and the grease cup given one
complete
turn.
Use a high melting
point
grease.
Every 100 hours apply 3 to S drops of medium engine
oil to the felt
in the top of the cam sleeve.
Do not
over-lubricate.
CHARGING
SYSTEM
Engines can be equipped with a 10 amp, 25 amp, or 30 amp
flywheel alternator system or a 37 amp belt driven alternator.
Instructions are located in rear of this manual.
FIRING
ORDER
The firing
order of the cylinder
is 1-3.-4-2,
and the
magneto and battery
type distributor
rotate
at one-
half engine speed, as is the case with conventional
'in line'
engines. The intervals
between the firing
of
the cylinders is 180 o. No. 1 cylinder is the one near-
est to the flywheel in the leftbank
of cylinders,
when
viewed from the flywheel
end of the engine.
No. 3
cylinder is the other cylinder in this bank. No. 2 cyl-
inder is the one nearest
to the flywheel in the right
bank of cyiinders
and No. 4 is the other cylinder
in
this bank. The cylinders
are numbered from 1 to 4 on
the air shroud near the spark plugs. See Fig. 1. The
flywheel
end of the engine is designated
the front,
and the power take-off
end, the rear of the engine.
SPARK PLUGS, Fig.

Incorrect
gap, fouled or worn spark plug electrodes,
will have an adverse affect
on engine operation.
Re-
move spark plugs periodically,
clean, regap or replace
if necessary.
Thread size is 18 mm.
Spark plug gap - 0.030 of an inch.
Replacement plugs must be of the correct
heat range,
like
Champion No. D-16J,
AC No. C86 commercial.
Tighten spark plugs, 25 to 30 foot pounds torque.
RESTORING COMPRESSION
In a new engine or one which has been out of opera-
tion for some time, oil mayhave drained off the cylin-
SET GAP
ders so that compression will be weak, causing diffi-
culty in starting.
To remedy this
condition,
remove
the sparkplugs
andpour about a fluid
ounce of crank-
case oil through the spark plug hole into each cylin-
der. Turn engine over several
times with the hand
crank to distribute
oil over the cylinder
walls.
As-
semble
spark
plugs
and compression
should
be
satisfactory.
HIGH TEMPERATURE SAFETY SWITCH
As a safety
precaution
against
overheating,
engines
can be equipped
with
a high temperature
switch
mounted to the cylinder
head at the No. 2 spark plug.
When cylinder
head temperature
becomes critically
high, the safety switch will automatically
stop the en-
gine by shorting
out the ignition
system. A waiting
period of about 15 minutes will be required before the
switch has cooled off sufficiently
to re-start
the en-
gine.
An overheated
engine will score the cylinder
walls,
bum out connecting
rod and crankshaft
bear-
ings,
also warp pistons
and valves.
The cause of the
overheating
condition
will have to be remedied before
the engine is re-started.
See Engine Overheats para-
graph in Troubles,
Causes and Remedies section.
KEEP ENGINE CLEAN - PREVENT OVERHEATING
(Agricultural and Industrial Engines)
This engine is cooled by blasts
of air which must be
allowed to circulate
all around the cylinders
and cyl-
inder heads to properly
cool the engine and thereby
keep it in good running condition.
If dust,
dirt
or
chaff is allowed to collect
in the cylinder shrouding
or in the V between the cylinders, it will
retard the
flow of air
and cause the engine to overheat.
Keep
flywheel
screen and rotating
screen clean,
so as not
to restrict
the intake of cooling air.
With reference
to Fig. 17; follow
the cleaning
and
maintenance
instructions
pointed
out,
to obtain
trouble free and satisfactory
engine performance.
