RADIATOR AND COOLING SYSTEM
Capacity: 6-1/2 quarts
The thermo-syphon system does not require
the use of a water pump but it is extremely
important with this system that the water
level in radiator never falls below the intake
where it enters radiator. Should this take
place, the water will cease to circulate due
to the break in continuity of water flow.
Overheating will result with possible damage
to the engine.
Radiator
The pressure radiator permits the use of a
higher operating temperature. The cooling
solution (pure water) will not boil in the
pressure radiator until a temperature of
230°F is reached. CAUTION: Do not re-
mOYJethe cap when the temperature is above
212 F as the cooling solution will break into
a violent boil which may splash on person
removing cap.
11
With the therIYXl-syphonsystem. it is unneces-
sary to provide thermostat, radiator shutter
or temperature gauge because the tempera-
ture is automatically controlled reducing
the possibility of condensation and corrosion.
Fan Belt
To adjust:
Loosen the generator adjusting screw and
move the generator away from cylinder block
until about 1'1 free movernmt at "A'lis obtained.
If fan belt bottoms in either of the sheaves the
belt should be replaced.
Extreme tightness will reduce the life of the
belt, generator bearings and fan shaft bearing.

down and continue turning to left until cap is
released. The pressure cap and vacuum valve
should be periodically checked for proper
functioning.
]f soda is used, mix with water thoroughly
before placing in radiator. Operate engine
about 2 hours. Drain and flush thoroughly
with clean water.
NEVER pour cold water in a hot engine.
Clean rain or 501t water should be used in
the cooling system if available. Hard or al-
kaline water will form scale which will impair
radiation if allowed to build up in the cooling
system. The use of washing soda will help
dissolve this scale. Where only hard water
is available washing soda should be used at
frequent intervals and before the accwnula-
tion of scale becomes heavy enough to scale
off and stop up the radiator passages.

STANDARD CAPPRESSURE CAP
open drain plug located on water inlet elbow.
This drains both the radiator and cylinder
block. Caution: Be sure to drain in freez-
ing weather. Loosen radiator cap to prevent
system from air locking which will retard
draining. Before and during freezing weather
it is advisable to fill cooling system with
anti-freeze. Because of the higher operating
temperature, alcohol should not be used,
Ethylene-glycol or its equivalent should be
used.

OILrNG SYSTEM
It Pays to Pay a Little More for Quality Lubricants.
Replace when oil begins to darken. Replace-
ment is usually necessary after 200 hours.
When adding new filter add one extra pint of
oil to oil sump.
The filter el~nt consists of a metal contain~r
packed witha special long thread filtering yarn.
Oil Filter
Insure your engine life by regular replacement
of filter. The oil filter is a highly efficient
unit for the purpose of filtering abrasive
particles from the crankcase oil.
CAUTION: Install only a new element which
is machine packed, to a specific density and
supplied by the Allis-Chalmers Mfg. Co. for
added, I extra pint must be added to oil sump.
Drain plug is located on bottom of oil sump.
o
For temperature above 90 F. use S.A.Eb 30;
for lowest expected temperature of 32 F.
Use S.A.E. 20: for lowest expected temper-
atures of 100 F. use S.A.E. 20W; for temper-
ature below 100 F. use S.A.E. lOW. Drain and
refill withfresh oil each 60hours of operation.

In addition to using high quality oils, it is also
necessary to use oil of proper viscosity. Oil
that is too heavy cannot reach all points to
be lubricated, therefore, it will cause undue
wear and engine sluggishness. Oil that is too
light will not form a protective film between
moving parts. For best results and to assure
lubrication between snug fitting parts, refer
to lubricants l!'ecommended in Lubrication
Guide.
Generally the oiling system needs no special
attention, except to change the oil regularly.
It is, however, advisable to remove the oil
sump once a year to clean it and the oil pump
screen.
Capacity 3 quarts. Maintain oil level to full
mark on oil gauge rod. When new filter is
Oil Sump
It has long been recognized that the life of a
tractor is largely determined by the kind of
lubrication it receives. Therefore, always
use oil and grease of high quality, manu-
factured by a dependable oil company that
has established a reputation for quality
products and whose success depends on main-
taining such quality.

Remove bowl, gasket and felt element. Note
which side of the element is up and be sure to

To clean the filter, shut off the fuel supply.
Loosen the bowl retaining nut and move bail

Check daily, clean when necessary.
For economy and performance use fuels
specified for your engine. For average loads
use 60 octane gasoline or higher. For con-
tinued heavy loads use 70 octane or higher.
The fuel filter is provided for the purpose of
keeping dirt and water from entering the car-
buretor. However, the best results are ob-
tained by using adequate fuel storage and hand-
ling facilities. 1£the fuel is kept free of dirt
and water by use of clean containers and
proper handling, the filter will have little

Fuel Filter:
Properly caring for the fuel system pays in
the long run. The cleaner you keep fuel
containers, tanks, lines, filter and carburetor,
the less time will be lost because of some
one part being plugged. Then too, because of
prevalent gUIn content in most higher octane
fuels, every drop of fuel should be drained
from both fuel tank and carburetor if the
tractor is not used for several weeks at a
time. 1£this is not done, the gum content will
form a shellac-like coating that will plug or
at least partially plug the fuel system, es-
pecially the jets in the carburetor. Your tank
wagon man can no doubt give you some help-
ful suggestions on the storage of fuel.

atmospheric conditions for idling speed.
1. To regulate idling speed of engine,
have engine thoroughly warm and ad-
just the idling stop screw on the throt-
tle shaft. The idle speed of engine
should be approximately 500 r.p.m.
2. For correct fuel mixture of idling
speeds of engine, adjust the idling
screw located on top of carburetor.
Turn adjusting screw inward for richer
mixture and outward for leaner mixture.
Normal setting is approximately one
and one-half turns out.
3. The main jet is not adjus table and
is fixed at a pre-determined size to
give economy and pe rformance.
Air Cleaner:
Clean and refill oil cup. Fill to level mark
using motor oil of the same viscosity as used
in oil sump.
A clean air cleaner adds life to your engine.
Service the air cleaner as mentioned in the
lubrication guide. Use the same viscosity
oil as used in the engine oil sump according
to the prevailing temperature. Keep the oil
cup filled to the proper level at all times.
Do not dilute oil or use used crankcase oil.
The efficiency of the cleaner depends on the
proper viscosity of oil. Under extreme dusty
conditions service air cleaner twice daily.

CLEANER
Each season remove the entire air.-cleaner
and clean main body and element thoroughly.
Keep all connections air tight.
The air cleaner should be removed at least
once every year, cleaned with solvent and
inspected for leaks. Air leaks will allow
dirt to enter. A plugged air cleaner will
cause excessive fuel consumption and lack of
power.

placing thumb in spark plug hole. Crank
slowly until air is forced past thumb. The
mark on fan drive pulley will be very near
inspection opening. Turn until centered.

cover should be in place and tightened snugly
to prevent battery from being damaged by
vibration. (Be sure that wood spacer is be-
tween top of battery and cover.) Any non-
insulated metal across top of battery will

Battery:
By taking frequent readings with hydrometer,
it is possible to keep generator charging
rate so adjusted as to have battery fully
charged, but not over charged. Whentaking
the reading, return the electrolyte to the
cell from which it was taken.
Incold weather, add water only immediately
before runningthe engine so that the charging
will mixthe electrolyte and water and prevent
freezing. A fully charged battery will not
freeze in very cold temperature, but if
onlypartly charged, will freeze and be ruined
at much higher temperatures. Weekly read-
ings of each battery cell should be taken
with a battery hydrometer. The readings
indicateas follows: 1.260, full charge; 1.220,
half charge; LlSO discharged.
Keep battery clean by using a stiff bristle
brush -- not metal. If terminals are cor-
roded or if the battery is acid soaked, wash
witha soda solution (1/4 lb. of soda to one
quart of water). Vent plug must be kept in
place when cleaning battery. After washing
battery check gas escape holes in vent caps
making sure they are open. If the battery is
removedfrom tractor, discoIU'lectthe grounded
positive terminal first. Whenreinstalling bE:
sure the ground cable is installed last and
connected to the positive post. Battery box
Due to the infrequent use of tractor in cold
weather and the extra amount of electrical
energy required by starting motor, it is
usually nec;.B-6saryto use a higher charging
rate than in summer, to keep battery fully
charged. Refer to instructions on light switch
for charginginformation.
Donot allow lighted matches or an open
flame of any kind to come in proximity to
battery cell covers. The need for frequent
~dition of water to battery, indicates the
charging rate maintained is too high.
The starting and lighting system uses a six
~lt battery, designed and built to meet the
requirements of the tractor.
Check the electrolyte (solution) in the bat-
tery at least once each week to see that it
is at the proper level. This level should be
maintained to lower edge of filler tube (which
is about 1/4" above top of separator). The
battery supplied with your tractor has a lead
washer type valve in the filler tube to prevent
over filling. Never add anything to the
solution except DISTILLED or RAINwater.
Boiledwater will not do. The supply of water,
should be kept in clean, covered vessels of
glass, china, rubber, or lead.

withbattery lead terminal in upper right hand
corner, have drain hole down. Rotate distribu-
tor in the opposite direction of rotor rotation
or counter clockwise until points just break.
Clamp distributor in this position with clamp
screw. Remove rotor, replace dust shield,
rotor and distributor cap. Place II 1 wire
directly above roto r. Proceed around dis-
tributor clockwise 113,1/4,112. Place coil
wire in center.
Point Gap: The point gap should be .02011 and
is set by turning engine until the points are
at their widest position or arm is on highest
side of cam. IT not .020" (determined with
feeler gauge) loosen the two screws in the
fixed point and turn CaInscrew until this gap
is obt<).ined.After tightening screws recheck
the point gap.
GENERATOR CHARGE RATE &LIGHT SWITCH
Light Switch and Generator Control
The generator has two charging rates. These
are controlled by the light switch.
Whenthe light switch is pushed all the way in,
the lights are off and the charging rate is about
3 aInperes. When the switch is pulled out to
first notch the lights are on and the charging
rate remains about 3 amperes. When the
light switch is pulled all the wayout the lights
are off and the charging rate is increased to
about 10 to 13 amperes. This latter position
should only be used when through some ab-
rormal condition the battery is in partially
discharged condition. In most tractor oper-
ation the trend will be to overcharge the bat-
tery.
Ammeter:
The ammeter indicates the charging or dis-
charging rate of battery. IT ammeter should
register discharge with lights off, discon-
nect the battery cable, to prevent the dis-
charge of battery, uritil the difficulty is
is located and corrected.
The cut-out relay, attached to generator case,
prevents the battery from discharging through
the generator when generator is idle.
Fuse
The light circ uit is provided with a fuse. 18
This fuse is located on the instrument box.
Coil:
The coil is mounted on switch box bracket
and should be kept clean and dry and con-
nections from switch to coil and coil to dis-
tributor in good condition.

Spark Plugs
Incorrect plugs are shorter lived and cause
poor engine performance.
Spark plug gap should be set properly; gap
too wide will cause missing on heavy loads
and lack of power •
Gap too narrow will cause missing, }foor
idling and engine to die at slow speed.
The spark plugs should be removed ever-y
200hours of operation, cleaned and the points
respaced. The point gap should be set at
.02511• Make this adjustment by bending the
outside electrode. Never bend center elec-
trode.
Use AutoliteAN7,AC45or Championj8 plugs.
The spark plugs and cables should be main-
tained in good condition and free of dirt and
grease. In the event of ignition difficulties
they shouldbe checked before openingup dis-
tributor.
Generator:
The generator charging rate is controlled
by a resistance unit built into the light
switch. This resistance unit limits the amowrt
of current allowed to flow through the field
coils of the generator.
The tractor is shipped with the field wire
on the generator disconnected. This wire
must be connected in order to coxnplete the
circuit. IT the battery is removed and the
engine must be operated without the battery

stopped, the ammeter will show "discharge."
Disconnect the battery ground cable until the
difficulty is located.
For best results, remove the generator and
have it checked by an author ized service
station.
If the ammeter fails to show a charging rate
one of the following may be the cause:
1. Loose or corroded wire connections.
2. Broken wire s.
3. Faulty ammeter.
4. Oily or gummy generator brushes or
commutator.
5. Worn generator brushes.
6. Cutout failing to close circuit.
Lock clutch pedal downwhen in storage.
The proper clearance of 1/16" must be main-
tained between clutch release levers and the
clutch release bearing not measurable from
outside except at pedal.
This adjustment is made externally on the
clutch throwout rod at anchor pin. This
should be adjusted so that the clutch pedal
has approximately 1" of free pedal travel.
Screwing in on nut brings throwout bearing
closer to fingers.
To Adjust Brakes:
The brakes should be adjusted as evenly as
possible so that the brake latch may be en-
gaged and still be effective. IT the brake is
adjusted too tight the latch cannot be engaged.
To adjust brakes, raise rear wheels off ground
and block under axle housing. Start with left
brake as it has lock. Before remQving rod
loosen locknutto keep rod from turning. Turn
rod in until a slight drag is felt on wheel at
1-1/2" pedal deflection. Adjust so both pedals
are equal. Whenends of threads are reached
the lining will be worn to rivets necessitating
replacement. Insert rod in pedal from left
side.

The cutoutrelay provides a switch for closing
the generator circuit. If the points in the
cutout fail to close the ammeter will remain
at zero. Do not operate the tractor in this
condition as damage to the generator will
result.
in place, disconnect the field wire to prevent
damage to the generator.
The generator very seldom causes any dif-
ficulty, however, if it does it is usually
caused by a dirty or oily commutator. To
clean, remove the band over the brushes.
Use grade "DO" sandpaper. With the engine
running hold the sandpaper against the com-
mutator. Do not use emery cloth or paper
as emery will cause short circuiting.
