SAFETY PRECAUTIONS
f)
Many hours of lost time and much suffering is
caused by the failure to practice simple safety
Tules.
IT IS TOO LATE TO REMEMBER WHAT SHOULD
HAVE BEEN DONE AFTER THE ACCIDENT HAS
HAPPENED.
1. Do not fill fuel tanks when engine is hot or
while using a lantern or when smoking.
2~ Do not attempt to oil or grease a machine
Or tractor while it is in operation~
3~ Do not wear loose fitting clothing that may
be blown into nloving parts.
4. Keep all shields and guards in place.
5. Place gear shift lever in neutral position
when starting engine or dismounting from tractor.
6. Machinery should be only operated by those
who are responsible and delegated to do so.
7. Only one person - the operator - should
be permitted on tractor when it is in motion.
8. The rate of travel on hillsides or curves
should be regulated so there is no danger of
tipping.
9. Do not remove radiator cap when engine
teITlperature is above 2lZoF.
10. Steering brakes and clutches should be pro-
perly adjusted.
11. Do not drive too close to the edge of a ditch
12* Never operate your tractor in a closed gar-
age Or shed.
13. When tractor is hitched to a stump Or other
heavy loads, always hitch to drawbar and never
take up slack in chain with a jerk.
14. Always keep tractor in gear when going
down steep grades.
15. Do not leave the engine running unattended
when anyone is adjusting or repairing a driven

GENERAL INFORMATION
The standard Model tractor is available with either a gasoline
engine, H4, or a Diesel engine, HD41 which are naturally
aspirated, open combustion chaInber engines. Power from the
engine is transmitted through the torque converter and to a
constant mesh helical gear transmis sion. From the trans-
rnission the power is transmitted to the spiral bevel gear and
from the spi ral bevel gear through the multiple disc steering
clutches to the final drives and the track sprockets. The trans-
mission provides 3 forward speeds, 1.81 M.P.H. in 1st; 2.81
M.P.H. in 2nd and 4.88 M.P.H. in 3rd; and 3 reverse speeds
of 2.09 M.P.H. in 1st; 3.24 M.P.H. in 2nd and 5.63 M.P.H.
in 3rd, at rated engine speed of 2100 RPM, and 1 to 1 converter
ratio~
The standard tractor is equipped with electric starting and
panel lighting equipment, suction type cooling fan mounted in
center of tractor, muffler, dry type air cleaner
t
torque con-
verter J neces sary gauges and sending units ~

LUBRICATION &. SERViCE INSTRUCTiONS
To prevent minor irregularities from developing
into serious conditions that might invo lye shut-
do'h'11 and rna.jor repair, several other checks and
services must be included at the same intervals
as lubrication. These checks and services will
reveal the need for adjustment or change due to
normal wear
1
which if neglected could result in
failure and shut-down. Refer to Lubrication and
Service Instruction Plate and the illustrations
and instructions in this Topic for points to be
serviced and their relative locations.
Thoroughly clean all fittings, caps, plugs, etc ~
before servicing to prevent dirt from entering
while performing the service.
Lubricants should always be at operating tem-
perature when draining fcr oil changes.
Oil systems equipped with an oil level gauge rod
having 1I0perating Range
ll
marks, are safe to
operate when oil level is anywhere within the
1I0 pera ting Range
l1
~
After refilling systems at oil change intervals,
the oil level should be checked after engine has
been run at low idle speed for a few minutes to
insure that engine clutch, heat exchangers~
filters, lines, etc. are fully charged before oil
level check is made.
NOTE: Oil levels will rise higher within the
II Operating Range

LUBRICATION & SE~VICE GUIDE
1. ENGINE COOLING SYST EM
Check cooling system every day for propel'
coolant level. The level should be obtained so
the coolant is visable in the radiator neck. Do
not over fill, as it is necessary to have space
for expansion when coolant is at operating tCtn-
peratures. If over filled, as coolant expands
J
it will be forced out through over-flow pipe ..
PRESSURE RADIATOR
The pressure radiator permits the use of a
higher operating temperature. The cooling so-
lution (pure water) will not boil in the pres-
sure radiator until a tctnperature of 221°F. is
reached.
To remove the radiator cap, tUrn to the left
until it stops. Push down and continue to turn
to the left until cap is released ..
f)
- Do not remove the cap when the temper-
~ ature is above 21ZCF. as the cooling solu-
. tion will break into a violent boil which
may splash onto person rernoving cap.
Never pour co ld wa ter in a hot engine. Clean
rain or soft water should be used in the cooling
system if available. Hard Or alkaline water wiU
form a scale which will impair radiation if al-
lowed to build up in the cooling system.

Soluble oil is beneficial to the cooling system.
It will not prevent the accumulation of lime,
but will retard such inforlT.ation. This water
soluble oil may be secured from your Allis-
ChalrneTs Dealer.
OPERATING TEMPERATURE
The operating temperature of the e..~gine coolant
is shown on the temperature gauge. The point
should operate in the green portion of gauge,
with a range of 160
0
to 220
0
F. If pointer moves
iYlto the red portion of gauge, the engine is Over-
heated. If engine does become overheated for
some reaSOn or other_ allow time to cool fur a
few minutes~ then add water slowly to radiator
while engine is idling.
Low engine operating terrperatures cause COn-
densatio:!1, sludge and corrosion. Keep engine
hot. The temperature is therrrlOstatically con-
trolled, but to prevent damage to the engine by
cold operating temperatures the engine must be
operated in the operating range on gauge long
enough to boil or drive off the moisture collected
in the initial warm-up period~
Operate engine in the normal range for a period
of time equal to the time it took the indicator
needle to reach the operating range before shut-
ting off engine. This will prevent moisture
from condensmg and damaging vital engine parts.
Under abnormal or cold engine temperature
operation, the oil change interval should be per-
forrned rrore frequently than under normal oper-
ating temperature conditions*

TO DRAIN COOLING SYSTEM
Open the drain cock at left of radiator, ahead of
brake pedals and remove plug on R~ H. side of
cylinder block.
CAUTION: In freezing weather be sure to drain
all places~ Loosen radiator cap to prevent sys-
temfrorn air locking. which will retard draining.
Stay near tractor and make sure system is com-
pletely drained.
2. FUEL SYSTEMS
FUEL SPECIFICATIONS (DIESEL)
The diesel fuel should be a natural distallate
petroleun1 oil and must have certain qual tties in
order to ignite and burn at the proper rate and
temperature. Field experience has shown that
the fuel best suited for this engine closely ap-
proxi.mates the following specifications:

For satisfactory fuel flow through lines and
filters in cold weather, the pour point of the fuel
must be at least 10°F. below the prevailing
atmospheric temperature.

The API gravity of a fuel varies with its specific
gravity. The low API fuels are desirable be-
cause they have a high specific gravity and more
heat units per gallon. However, the highet" the
APIgraY;'ty, t:he better will be the ignition quality
of the fuel.
The ignition quality of a fuel is expressed as a
11cetane nurrb
er
". The higher the ectane number
the higher the quality of the fuel. The higher
c etane fuel shortens the ignition delay period to
facilitate starting and improve combustion. The
diesel index number, which is a dose approxi-
mation of the ectane number~ is a field method to
r epres ent ignition quality.
The distallation 90% point and the end point are
lrnportant. High volatility is required to enable
complete vaporization of the fuel, clean com-
bustion and low residue formation.
The flash point of the fuel has no quality sig-
nificance, but is important with respect to
safety in storage and handling of the fuel •
It is wportant that the fuel be within the specified
linlits for ash) carbon. water and sediment con-
tent etc. to prevent excessive wear and danlage
to engine parts.
It is also important that the fuel has lubricating
properties so that the fuel injection pump and
fuel injection nozz"!..es are adequately lubricated~
In instances where fu e1 with inadequate lubri-
eating properies must be u sed, one quart of
SAE lOW engine oil must be added to every 10
gallons of fuel to provide the necessary lubrica-
tion. Contact the fuel supplier and follow his
recommendations as to whether or not engitlc oil
should be added to the fuel.

CAUTION: The sulphur content of diesel fuel
should be as low as possible. The fuel should not
contain a sulphur content of more than 1/2 of 1%.
Generally speakingJ a No.2 high speed diesel
fuel purchased froIT' a reputable oil company
wilirr:eet the above specifications.
FUEL SPE CIFICAT IONS (GASOLINE)
This engine is designed to burn regular gasoline
having an octane rating (research method) of 89
or higher. Fuel cornpanies provide fuels tailored
to f'reet the existing weather conditions. These
fuels are changed at the start of the predorninent
seasons according to regional weather trends.
Fuels are tailored to give ease of starting in
cold weather and to give a low vapor pressure
to avoid vapor lock. An effort should be made
to purchase fuels in such quantity that they are
not carried over to succeeding seasOns.
FUEL FILTER BOWL - GASOLINE & DIESEL
Check daily and clean when water or sediment is
visable. Clean filter element when necessary.
The fuel filter is located at bottom of fuel tank
and is provided for the purpose of keeping dirt

and water from entering the carburetor,t or fuel
injection pump. However, the best results are
obtained by using adequate fuel storage handling
facilities.
If the fuel is kept free of dirt and water by use of
clean containers and proper handling, the filter
will have little work to perform. Excessive
cleaning of filter indicates dirty fuel.
To clean the filter, shut off the fuel supply.
Loosen the bowl retaining nut and !nove bail to
one side. Remove bowl, gasket and screen~
When installing, a ssemble as shown to provide
the proper seal. Filter screen next to bowl and
gasket next to head.
The element can be cleaned, using a small stiff
brush.
It is advisable to keep extra bowl gaskets on hand
as the gasket is liable to leak after cleaning bowl.
Turning the shut-off valve wide open will seal fuel
from the packing gland and prevent leakage in the
open positi.on~ When valve is shut off, the pack-
ing gland nut Inust be snug to prevent leakage.

FUEL FILTER (HD-4 DIESEL)
The fuel system is provided with a primary and
secondary fuel filter nlounted in one element on
the side of the engine.
The purpose of the fuel filter is to renlovewater.
sediment f$ abrasives from the fuel, before the
fuel enters the injection equipment. The proper
handling and storage of fuels will increase the
life On the filters.
Replace the filter element at each 500 hours of
operation. Poor fuel handling and storage facil-
ities will decrease the effective life of the filter.
In other words, dirty fuel will decrease the life
of a filter. while clean fuel will increase the life
of a filter. Never operate until filter becomes
plugged, or to a point to where a decrease in
engine speed Or power is noticed. SODle dirt
may seE'k its way through the secondary filter and
cause severe damage to the fuel injection equip-
ment.
Each time the filter element is removed, it may
be necessary to bleed out air by remov1t:..g the plug
at top of filter head assembly. Remove air bleed
plug and turn On fuel valve at tank. Operate the
hand priming pump until all air has escaped and
solid fuel is to the level of the air bleed plug
and install bleed plug at top of filter head.
FeEL STORAGE
The importance of proper storage of fuel cannot
be too strongly stressed. Storage tanks, drums,
or service tanks must be free of rust, scale,
sediment, or any other foreig:c. matter which will
contaminate the fuel. Contaminated fuel will clog
the engine fuel filters and eventually damage the
fuelilljection puIl1' and the fuel injection nozzles.
A portable storage tank provides the best method
for storing fuel on the jo b. In such a tank, the
sediment and water can easily be drained and the
fuel can be pumped into the tractor fuel tank with
a minimum of handling. Since condensation will
occur in the storage tank" it is very important
that a sediment sump be pro'vided i1':. botton) of
tank so that water and sediment can be drai:!1ed
daily.
Fuel should be allowed to settle at least 48 hours
i.n a storage container before being added to the
fuel tank of the tractor, It is advisable to use a
pun1p and draw the fuel frorn storage tank, or
barrel, rather than to drain it from bottom of fuel
container. Vihere conditions are such that drums
must be used to supply fuel, it is advisable to
have enough drums to allow sufficient time for the
fuel to settle~ The fuel thus left in a number of
drums CaZ'l be collected into one drum and used
after the usual time allowed for settling. L"1 this
manner, the sediment and fo reign matter will be
disposed of and no fuel will be wasted. Whenever
drums are used for fuel storage, they should be
covered Or placed under shelter so that the fuel
will not becon1e contaminated by water I which
will enter through the filler plugs when it rains,
even though plugs are ti.ght.
The fuel tank of the tractor should be filled at end
of the day's run rather than at the start; this will
reduce the water content
J
as a full tank is less
subject to cor.densati.on.
