GENERAL INFORMA TION
The Model HD-4 Crawler Tractor is powered by a
4 cylinder, 4 cycle, oper.. cOll1bustion chamber,
direct injection ALLIS-CHALMERS Model 2200
Diesel Engine.
Engirue power is transmitted through a torque con-
vertor. Torque is multiplied to a 2. 15 to 1 ratio,
by the convertor and transrnitted to the power
shuttle clutch and to a constant mesh helical gear
trans::.nission. Frolll the transmission, the power
is transmitted to the spiral bevel gear and from
the spiral bevel gear through the multiple disc
steering clutches, to the final drives and the track
sprockets.
Forward and reverse direction, in any speed
range, is obtained through the power shuttle
clutch.
The transmission provides 3 forward speeds and
3 reverse speeds. In f01--wardt ranging froID 1. 81
MPH in I st gear to 4.88 MPH in 3rd gear. In
reverse, ranging froD} 2. 09 in 1st gear to 5.63

LUBRICANTS AND FUELS
MOTOR OIL
Motor oils are designated by code letters as
follows: DG - DM - DS.
The letters denote the type of service for which
the unit is used.
DG - Diesel General Service
DM - Diesel Medium Service
DB - Diesel Servere Service
OIL USED IN THE ENGINE CRANKCASE SHOULD
MEET THE AMERICAL PETROLEU1v1 INSTITUTE
(API) DIESEL CLASSIFICATION OF DS SERIES
3 DIESEL OIL.
Heavy duty oil of the DS classification provides
the most satisfactory lubrication for ALLIS-
CHALMERS Diesel engines. These oils use ad-
ditives to lower the pour point and to protect the
engine from corrosion~ They help to keep the
engine free from varnish
J
sludge and deposits ..
Unless the oil has the proper additives, fuels
with a high sulphur content cause excessive
piston ring and cylinder liner wear, excessive
oil consumption and piston ring sticking.
If a fuel with more than. 50/0 sulphur content
must be used
t
the oil change interval should be
shortened.
Oil designated DS SERIES 3 contains certain ad-
ditives to increase film strength, to be COr-
rosion resistant
l
to carry contamination in sus-
pension and as pour point depressants, etc.
The fact that the oil has the ability to carry
contaminants in suspension rather than deposit
them in the engine, causes the oil to discolor
rapidly. Thus, the color of the oil cannot be
used to determine when to change. (Follow the
interval given in the Lubrication and Service
Guide).
FUEL SPECIFICATIONS
FOR ECONOMY AND PERFORMANCE USE
FUELS SPECIFIED FOR YOUR ENGINE.
Fuel used in the ALLIS-CHALMERS Diesel en-

NUMBER 2 HIGH SPEED DIESEL FUELS GEN-
ERALLY MEET THE ABOVE SPECIFICATIONS.
Some of the more desirable high speed diesel
fuels do not have a low enough pour point for be-
low zero operation and cause filter plugging,
which in turn causes hard starting. In this event1
a winter grade fuel of the same type should be
obtained
4
Pour point of fuel must be at least lOaF. below
prevailing atmospheric temperature for satis-
factory fuel flow through lines and filters.
API gravity of fuel varies with its specific grav-
ity* Low API fuels are desirable because they
have high specific gravity and more heat units per
gallon.. HOVlever, the higher the API gravity, the
better ignition quality of fuel will be.
Ignition quality of fuel is expressed as a Hcetane
numberll. Higher cetane number: higher quality
of fuel. Higher cetane fuel shortens ignition dela y
period to facilitate starting and improve com-
bustion~ Diesel index number, which is a close
approximation of the cetane number, is a field
nu"!thod to represent ignition quality.
Distillation 90% point and end point are impor-
tant. High volitility is required to enable com-
plete vaporization of fuel, clean combustion and
low residue fonnation.
Flash point of fuel has no quality significance,
but is important with respect to safety in fuel
storage and handling.
It is important fuel be within specified limits for
ash, carbon, water and sediment content, etc. to
prevent excessive wear and darnage to engine
par ts.
It is also important fuel has lubricating properties
so fuel injection pump and fuel injection nozzles
are adequately lubricated.
NOTE: Sulphur content of diesel fuel should be
as lOW' as possible; fuel should not contain sulphur
content of more than 1/2 of 10/0.
HANDLING OF FUEL
No fuel is satisfactory for use if it is dirty. A
few small pieces of dirt can cause costly damage
to the fuel injection pump, which is built of
closely fitted precision parts.

The following rules should cover the handling of
fuel before it reaches the fuel injection pump~
1. Do not handle fuel in open containers where
dust is blowing around.
2. Do not use waste or Hnty rags around fuet
containers or injection equipment.
3. Clean all st,,"zlge tanks at regular intervals.
4. If pumps are used to bring fuel from storage
tank to tractor, keep covered with dust proof
covers when not in use.
5~ vVhen clnptying a d rum or storage tank,
agitate as little as possible and leave appI·ax.i-
II
matelyone inch of fuel in bottom of tank or drum.
6. Keep all fuel handling equipment such as
measure, ftUmele, containers. etc. scrupulously
clean and keep thell1. covered when not in USe.
Cleanliness prevents difficultYa
IMPORTANT: The lubricant distributors and/or
suppliers are to be held responsible for the re-
sults obtained from. their prOducts. Procure
lubricants from. distributors and/or suppliers of
unquestioned integrity, supplying knowr.. and tested
products. Do not jeopardize your equipment
with inferior lubricants. No specific brands of
oil are recorlli--nended. Use only products quali-
fied under the following oil viscosity specifica-
tions and classifications and recolnmended by
reputable oil com.panies.

FUEL STORAGE
The importance of proper fuel storage cannot be
too strongly stressed. Storage tanks, dl'UlnS or
portable service tanks must be free from rust
scale, sedimen.t, or any other foreign ITlattel:'
which will contaminate the fuel. COEtaminated
fuel will clog the fuel filters and eventually
damage the fuel injection pump and fuel nozzles.
The most practical fuel storage seems to be an
elevated tank. wit'h an open sided roof: high enough
for air to circulate tank. This protects the fuel
tank from rain or snow and hot sun rays.
The fuel storage tank should be installed so that
one end of tank is slightly lower and equipped
with a drab: valve at the lower end for draining
off the sediment and water. The tank should also
be provided with a hose: equipped with a self
closing nozzle to pr event the entrance of dirt6
A portable storage tank provides the best method
of storing fuel on the job. Since all storage tanks
are subject to condensation, it is very iITlportant
that sediment sump be provided in the bottom of
the tank so that water and sediment can be drained
daily.
A portable storage tank should be provided with a
pump, so the fuel can be pwnped into the tractor
fuel tank witi1 a minimum of handling. Draining
fuel fror::1 supply tank into bu.ckets or other con-
tainers, then pouring it into the crawler tractor
fuel tank is not considered a good method of
handling fuel.
Fuel should be allowed to settle as long as pos-
sible i1: a storage container, before it is used in
the fuel ta..'Ll.: of the crawler tractor. This will
allow the sediment and water to settle to the
bottom of the storage container and permitting
cleaner fuel to be used in the crawler tractor
fuel tank.
Where conditions are such that drums must be
used to supply fuel, it is advisable to have enough
d rUITlS to allow sufficient time for the fuel to
settle before being used. It is also advisable to
use a pwnp and pltlnp the fuel from the drunl or
co:r:.tainer, rather than drain it from the bottom of
the fuel container.
The fuel thus left in a number of drwns can be
collected into one drwn and used after the usual
time allowed for settling. In this manner the
sedime:ct and foreign matter will be disposed of
and no fuel will be wasted.
¥lbenever drums are used for fuel storage. they
should be covered, or placed under shelter so
that the fuel will not become contaminated by
water, which will enter through the filler plug
when it rains, even though the plugs are tigbt.
The fuel tank of the crawler tractor should be
filled at the end of the day(s run. rat..."0er t:'1.an at
the start of the dayls rur... This will reduce the
water content of the fuel , as a full tank is less
subject to condensation.
