DIESEL FUEL SPECIFICATIONS
The best guide to follow when selecting
fuel for use in International diesel engines is
the set of fuel specifications prepared and
recommended by the builder.
Most refiners now market fuel oil des-
ignated as diesel fuel to distinguish it from
burner fuel. Although similar to burner fuel,
the diesel fuel is usually made from the
straight run distillates, while the burner fuel
may contain sufficient quantities of the lower
ignition, catalytic-cracked distillates to make
it unsatisfactory for use in the International
dieseI engine.
Some refiners are marketing one grade
of fuel for use in both diesel and burner ap-
plications. This fuel, when within the specifi-
cations shown below, can be aafelv used.
However, maintaining the quality and suit-
ability of these fuels for International diesel
engines is definitely the responsibility of the
supplier.
Diesel fuel for high speed diesel engines
is now obtainable in the U.S.A. in two grades,
namely No. I-D (light fuel) and No. 2-D
(heavy fuel).
No. 2-D fuel gives the most satisfactory
performance in International diesel engines
.when the physical properties are within the
limits of the following specifications:
Gravity - minimum 30 API
Elash point - minimum 125 0 F., or legal
our point - 10 0 lower than minimum
anticipated temperature
d point - preferably no more than
10 . h h . t

ulphur by weight 0.5% maximum
~etane number 40 minimum
.i)pper strip corrosion ..:: 3 hr. at 2120 F.
iIo r , 3 NPA maximum
When No. 2-D fuel conforming to the
above specifications is not available, the No.
I-D (light) fuel may be used. However, this
lighter fuel has a lower heat content and low-
er viscosity. Its use may result in loss of
power and/or increased fuel consumption and
shortened injection pump life. However, No.
I-D fuel may be required in sub-zero weather
in order for the pump to maintain an adequate
flow of fue 1. _
Fuels lighter than kerosene will not give
satisfactory perforinance in Inte rna tiona 1
diesel engines. Although some fuels meet the
No. 2-D specifications, their composition may
be such that unsatisfactory engine wear and
excessive deposits may result unless high
additive lubricating oil is used. Knowledge of
the fuels in your area and the types of crank-
case oils required for satisfactory perform-
ance with these fuels will avoid service prob-
lems. When in doubt, see your International
Industrial Power distributor or dealer.
Water and sediment will tend to clog the
filters. If water passes through them it will
corrode the pump plungers and other highly
finished parts in the pump and nozzles, thus
greatly shortening their lives. The fuel must
be free from water, sediment and residue.
Buy clean fuel and keep it clean. Store
fuel in tanks equipped with hose and nozzle
because the fuel is then less likely to be-
come contaminated. Do not use funnels, cans
and drums because they are difficult to keep
clean. Handle the fuel as little as possible.
Always fill the engine fuel tank at the
end of each day to reduce condensation.
Drain the water trap! daily.
Following these rules will pay dividends.

DESCRIPTION
The International TD-24 is a full track-
laying tractor powered by a 6 cylinder. diesel
engine. The principal components of the
tractor are the engine. engine clutch. trans-
mission. planet power drives. sprocket
drives, track frame and suspension assem-
blies, and hydraulic controls -,
Engine
Engine power IS supplied by a 6 cylinder.
4 cycle, valve-in-head diesel engine. Fea-
tures of this engine are: a counterbalanced 7
beaeing Tocco-hardened crankshaft, replace-
able cylinder sleeves, precision bearings,
full-flow "no-drain-back" pressure lubri-
cation system, and closed cooling system
with thermostatic controls.
Transmission and Clutch
The synchromesh transmission is moun-
ted on the front of the heavy steel rear main
frame. Dry sump pressure lubrication elim-
inates the power loss of gears churning in oil,
Two filter strainers clean the oil. The trans-
mission is a 4 speed gear box. with separate
lever for forward and reverse. The planet
power drive provides an instant high-low
range shift for each transmission gear. The
transmission is coupled by universal joints
to an enclosed 16 inch, 2 plate, hand operated.
over-center clutch attached to the flywheel.
Planet Power Drive
The hydraulically controlled planet pow-
er drive arrangement gives the tractor finger-
tip ease of steering. Hydraulic pr'essure for
__' the steering control is developed by an engine
driven hydraulic pump. The pressure is
stored in an accumulator with a heavy spring
piston, enabling the pump to run without load
most of the time. When pressure irithe ac-
cumulator falls, due to use of the steering
control levers. the pressure regulator will
open and allow the hydraulic pump to rebuild
-the pressure in the accumulator.
The high-low range planet power drive
units are in effect 2 compact heavy duty in-
dependent transmissions which can be shifted
.... instantly on-the-go under full engine power.
The planet power' drive consists of a
drive bevel gear bolted to a center hub, and
on each side are bolted housings containing
the planetary cluster gears. These cluster
gears mesh with the high and low range Sun
gear assemblies and discs. Also the sprock-
et drive pinion shaft gears mesh with the
planetary cluster gears and are splined to
the drive pinion shafts for distribution of
power.
The pivot brake disc assembly is held in
place on the sprocket drive pinion shaft by a
splined shaft and hub, and is used in braking
or holding the tractor in a firm position, or
for use when making a right or left pivot
turn.
The 3 brake discs on each side are
actuated by finger-tip hydraulic control,
there being 1 control lever with 3 different
positions for each side. With th_e2 levers
all the way forward the high range brake
discs are applied; with both levers in the
middle position the low range brake discs are
in action; and with levers all the way back the
tractor is stopped with both pinion shaft
brakes engaged.
Instant shift up of 1 gear is made by
pushing both steering levers forward from
the middle position. Shift down 1 gear is
made by pulling both levers back to the mid-
dle position.
To change to a pivot turn it is merely
necessary to pull the lever (in middle posi-
tion) back slightly when a "feathering" ac-
tion takes place; 'and to change to a full
pivot turn pull the lever all the way back.
To make a gradua-l turn with both tracks
pulling, the lever (on the side toward whrch "
it is desired to turn) is placed in the middle
position with the other lever forward. The
outside track will then travel 27% faster
than the inside track, making a gradual turn.
The spiral bevel gears, planetary clus-
ter gears and brake discs are located in a
large cornpa.rtrnent in the tractor rear main
frame. Planetary gears are amply lubrica-
ted by pressure and splash .

DESCRIPTION
Engine Speed Control
The engine speed control lever secures
governed speeds from 500+50 r.p:m. (low
idle) to l5Z5 ± 30 r.p.m. (high idle). With
the engine operating at 13.75r.p.m. full load
speed, the t rave Ling speed range is from
approximately l-l/Z to 8 m.p.h. forward, and
from l-l/Z to 8 m.p.h. in reverse. The syn-
chromesh transmission makes possible a
quick change from forward to reverse by
disengaging the engine clutch arid shifting the
left-hand lever: forward to go ahead, and
backward for reverse.
Track Frames
The track frames are 1 piece welded
steel construction. Regular tracks have 6
lower rollers and Z upper idlers on each
side. The large bearings and the new type
seals allow high tractor traveling speeds and
long periods between track roller lubrication.
A series of saucer-like bellville springs in
an enclosed cylinder permits the front idlers
to recoil under heavy shock but holds them in
position against full load track pull when the
t ractor travels in reverse.
Sprocket drive gears are mounted on
sleeves independent of the track frame pivot
shaft. Shock loads on the track frames,
therefore, do not affect gear alignment.
Track frames are relieved of leverage loads
and track alignment is maintained by the
same arrangement that has been so success-
ful on smaller sizes of International crawler
tractors.
Sprocket Drives
The sprocket drives consist of sprocket
drive gears and pinions which provide a fixed
gear reduction and transmit power out to the
tracks. Gears arid vs procke t s are roller
bearing mounted on sleeves. Sprockets are
reversible, making it possible to use both
sides of the teeth.
OR1ENTATION
Throughout this manual the use of the
m.s "left" and "right," and "front" and
"rear," must be understood to avoid con-
fusion when following instructions. Left and

DESCRIPTION
INSTRUMENTS AND CONTROLS
The operator of this tractor should
thoroughly familiarize himself with the in-
struments and controls provided for opera-
tion. There are important differences be-
tween various tractors; therefore, regard-
less of previous experience with other ma-
chines, the operator should fully understand
what each control is for and how to use it,
before starting to operate this tractor.
Starter Button
Pressing this button completes the eIe c-
trical circuit between the battery and the
starting motor, causing the starting motor to
crank the engine. Release the pressure on
this button as soon as the engine starts.
Never operate the starting motor more than
30 seconds at a time. If the engine fails to
start in 30 seconds, allow the starting motor
to cool 2 or 3 minutes and repeat the start-
ing operations.
Choke Control Rod
The choke aids in starting the engine
when it is cold. Pulling out the choke re-
stricts the flow of air to the carburetor,
giving a rich mixture. Avoid over choking,
as excessive use of the choke will flood
the engine and make it hard to start. Af-
ter the fir st few revolutions of the engine,
push the choke in half way or to a point
where the engine operates steadily. As the
engine warms up push the choke all the way
in.

Primer Button (H Used)
In cold weather the engine starts easier
if primed. A few strokes of the primer
button, which sprays raw gasoline directly
into the intake manifold, is usually sufficient.
The number of strokes will depend on the
atmospheric temperature.
Radiator Shutter Control Rod (H Used)
This control rod is used to regulate the
radiator shutter attachment, which is closed
tight when starting, opened wide in normal
operation, or set in any intermediate posi-
tion (pa~e 97).
Compression Release Rod
This control rod is used to convert the
engine from gasoline to diesel fuel operation
when starting, or from diesel to gasoline
when stopping. To place the engine in the
gasoline cycle for starting, pull the rod back
toward the operator; be sure the rod latches
securely in position. To switch the engine
from diesel to gasoline operation, push the
rod all the way in.
Engine Speed Control Lever
This lever controls the speed of the
engine from low idle to maximum. When
set in a given po s.i ti on it maintains a uni-
form engine speed under variable loads.

DESCRIPTION
INSTRUMENTS AND CONTROLS - Continued
Move the lever upward to increase the
speed.
Ignition and Light Switch
To start the engine, turn the switch
clockwise and hold in position approxi-
mately 5 seconds after the engine starts;
then release the switch. To operate the
lights, turn the switch counterclockwise.
The fir st position is for all lights including
the head, tail and dash lights; the second
position is for the head and tail lights only;
the third position if for head lights only.
Gearshift Levers
The forward and reverse gearshift
lever is on the left side of the operator. To
go ahead shift this lever forward arid for re-
verse shift it backward. It is always used
regardless of the speed selected. The se-
lective gearshift lever is on the right side
of the operator. It has 4 speed positions.
Using these levers in conjunction with the
hydraulic control unit (which is equipped with
high and low speed ranges) makes 8 forward
speeds and 8 reverse speeds available.
Engine Clutch Lever
This lever is used to engage and disen-
gage the engine from the transmission. Al-
ways completely disengage the engine clutch
when shifting gears. Disengage the engine
clutch by pushing the lever all the way for-
ward.
Brake Pedal and Lock
The brake pedal is used for slowing
down or for stopping the tractor. It has a
locking device for use when park ing the
tractor on a slope. To lock the brake, push
the pedal down and lift up the lock lever,
which engages a pawl and ratchet. To un-
lock, push down on the pedal and release
the lock.
Hydraulic Controls
The two hydraulic control levers apply
the brake discs of the planet power drive
mechanism and thus steer the tractor and
determine the high or low speed range.
Each of the 2 levers functions in 3 positions
as shown in Ll Lus t , 7 -- "A" (forward)
controls the high range brake disc and sun
gear; "B" (middle position) controls the low
range brake disc and sun gear; "C" (back-
ward) controls the pivot brake disc and hub.
Only I ofthe brake discs on each side is

applied at any time; the other 2 are turning
free.
The high speed range is in operation
when both levers are in the forward posi-
tion "A." The low range is secured when
both levers are in the middle position "B."
To make a gradual right turn with the
levers in high range position, pull the right-
hand lever into the low range position. To
make a gradual right turn with the levers in
low range, push the left-hand lever into
range. For a left-hand turn, reverse this
procedure.
To make pivot turns, the levers are
first placed in the low range position "B"
and then the lever is pulled back into the
"C" position on the side toward which the
turn is to be made. However, when the
lever is pulled back slightly a "feathering"
action starts, enabling the operator to make
a gradual or full pivot turn; this feathering
action continues until the "c" or pivot po-
sition is reached.
Heat Indicator
This instrument indicates the tempera-
ture of the liquid in the cooling system. The
indicator hand should be in the high side of
the "RUN" range when engine is operating.

Fuel pressure rind icator ,
Fuel Oil Pressure Indicator
This indicator, located on the injection
pump, registers the pressure of the fuel oil
from the prirnar y pump through the final
fuel filter to the injection pump. With the
engine operating (either gasoline or diesel
cycle) the pointer should be in the white area
or "OPERATING RANGE." If the pointer
remains in the red or "CHANGE FILTER"
area, the auxiliary or final filter element
heeds replacement.
Engine Oil Pressure Indicator
The indicator hand should be in the

Transmission Oil Pressure Indicator
The indicator hand should register pres-
sure in the white area for normal operation.
(The indicator will not register pressure
when the engine clutch is disengaged.)
When the engine is first started the
indicator hand will move into the red area;
as the oil in the transmission warms up,
the hand will gradually enter the white area.
If the hand remains in the red area after
the oil has warme d up, the transmission and
planet power drive oil filters should be
cleaned. If the hand still remains in the red
area or fails to register pressure, stop the
engine and refer to your International
Industrial Power distributor or dealer hefore
operating. the tractor.
Ammeter
This instrument indicates the charging
rate of the generator or the rate at which
the battery is being discharged. The am-
meter should show charge whenever the en-
gine is operating at a speed faster than low
idle speed. If it shows discharge continuous-
ly .whfl.ethe engine is operating at any speed
above the idle speed, the cause should be
investigated to avoid completely discharging
the battery and possible darna.ge to the
generator.

OPERATION
~, "' '
BEFORE STARTING A NEW TRACTOR
Inspection
Make a complete inspection of the trac-
tor for any shortage or damage which may
have occurred while being shipped. Make
sure that ali component units are securely
and properly mounted.
Lubrication
Lubricate the entire tractor. Refer to
"LUBRICATION" on pages 38 to Q8.
1. Check the oil levels of the engine
crankcase, air cleaner oil cup, fuel injection
pump, hydraulic system, and all gear cases,
to see that they are filled to the correct levels
with the proper grades of oil for the prevail-
ing temperature. Refer to specifications of
lubricants on pa~es 40 and 42.
2. The transmission and planet power
drive oil filters should be removed and
cleaned. Refer to Note 2, in the "LUBR ICA-
TION GUIDE" on pages Q2 and Q3.
3. The hydraulic oil filte.rs should be re-
moved and cleaned. Refer to "HYDRAULIC
SYSTEM" on page 50.
4. The lubrication procedure above is
necessary only in starting a new tractor or
one that has been idle for a long time. For
procedure in starting a tractor that has been
removed from storage, refer to pa~e 88.
5. Tractor s shipped to destinations in
the United States of America, Canada, and
Mexico have all the lubricant compartments
filled with oil at the factory. The lubricant
in the crankcase, air cleaner, and fuel injec-
tion pump is for preservative purposes only
and is not suitable for use in regular serv-
ice. The original oil should be d ra irie d from
the crankcase, air c Ieaner ; and fuel injection
pump and be replaced with the proper grade
for the prevailing temperature.
6. Tractors for export shipment have
all oil drained from the crankcase, air cleaner,
and fuel injection pump.
7. As a precautionary measure, it is
advisable to lubricate the front idlers and the
track rollers and idlers on a new tractor after
'each 16 hours of operation, and. depending on
the amount of lubricant required, gradually
increase the lubrication interval to that speci-
fied in the It Lubrication Guide II on taees 42
and 43.
8. For further information refer to
"LUBRICATION" on pages 38 to Q8.
Breaking - In Speed
Operate a new tractor with a light load
for the first 30.to 36 hours at a governed
speed from 1450 to 1500 r.p.m.
Fuel System
Check to see that you have an adequate
supply of fuel in both' the gasoline e nd jdi.e seI
fuel tanks; also thai fuel tank shut-off valves
are open. Be sure that all fuel is dependable
quality, clean, and free from water. For
further information refer to "FUEL SYSTEM"
on pages 65 to 71.
Cooling System
1. Check to see that the drain cocks on
the lower right side of the radiator and the
left side of the crankcase are closed.
2. Be sure that the radiator is filled with

clean water. Use soft or rain water and rust
preventive if possible. Be sure radiator cap
IS on tight.
3. Check the tension of the fan belts.
The tension is correct when the belts can be
depressed by the thumb 3/4 to 1 inch, mid-
way between the pulleys. If the tension is not
cor r e.ct, adjust (page 57).
4. If the tractor is to be operated in
freezing temperatures, refer to "COLD
WEATHEROPERATION"on page 25.
5. For fUrther information refer to
"COOLINGSYSTEM"on pages 55 to 58.
Electrical System
1. Be sure the terminals are clean and
bright on the 2 disconnected battery cables at
the starting motor. Connect the' short cable
(negative) to the starting motor and the longer
cable (positive) .to the solenoid.
2. Check to see that the distributor is
securely mounted in place and was not dam-

aged or cracked in shipment. Check the spark
plug cable s to make sure they are securely
connected in the distributor cap and at each
spark plug.
3. Check to see that all electrical termi-
nals are clean and securely fastened.
4. Service the batteries as instructed on
the tag attached. Check the level and specific
gravity of the electrolyte in the batteries
(pa~e 82).
5. POLARIZING THE GENERATOR. Do
not start the engine until the generator has
been polarized. After all cables and wires
have been connected, correctly polarize the
generator to the batteries by placing a jump-
er lead momentarily across the II BAT" and
"GEN" terminals of the regulator. This
allows a momentary surge of current to flow
through the generator and to polarize it cor-
rectly. Failure to do this may result in severe
damage to equipment, since reversed gener-
ator polarity can cause the relay contact '
points to vibrate, arc and burn, can run the
battery down, and possibly can seriously
damage the generator.

OPERATION
PREPARING FOR EACH DAY'S WORK
Lubrication
1. Change oil in the air cleaner oil cup.
2. Be sure the oil in the crankcase is up
to "FULL" level mark on the bayonet gauge.
3. Check for any leakage from the lubri-
cant compartments.
4. For complete lubrication requirements
refer to "LUBRICATION" on pages 38 to ~8.
Cooling System
1. Remove the radiator cap and check to
see that the water comes up to a level slightly
_, below the filler opening.
NOTE: In moderate temperatures (above 32 0
F.) the engine should never be started unless
the cooling system is properly filled with
water. In lower temperatures refer to·
"COLD WEATHER OPERATION" on page 25.
,
Fuel System
·1. Lift the seat cushion and check to see
that the diesel fuel shut-off valve is open.
2. Check to see that the gasoline shut-
off valve is open (Ll lus t, 6).
3. Check to see that there is an ade-
quate supply of fuel in the fuel tanks. Fuel
tanks should be filled at the end of each
day's operation to prevent moisture from
colle cting in the tanks.
4. Be sure to use a well known grade of
clean fuel. Keep the containers or drums
clean at all times. Carefully strain all fuel.
5. In order to be safe from contam-
inated fuel, do not use the Iast few gallons
out of each drum or storage tank, but pour
this into a separate storage tank and save
it until the tank is filled .. This fuel is
allowed to settle and can then be used down
to the last few gallons; the remainder should
not be used for fuel.

OPERATION
OPERATING PRECAUTIONS
1. SAFETY FIRST. Never fill the
gasoline tank when near an open flame or
when {he engine is operating. When pouring
in fuel, keep the funnel and container in con-
tact witHthe metal of the fuel tank to avoid
the poss1ibllity of an electric spark igniting
the gas. Never light matches near gasoline;
as the air within a radius of several feet is,
permeated with a highty explosive vapor.
',2. Fuel and gasoline tanks have air vents
in the filler caps. These vents should be
kept open at all times to assure proper flow
of the fuels.
3. If difficulty is experi.enced in starting
on gasoline in cold or damp weather, the
spark plugs should be removed and any con-
densation wiped off. At the same time check
the spark plug gap, which should be 0.035 to
0.040 inch. After drying the spark plugs
reinstall them in the engine and start as
usual.
4. Never operate the starting motor
more then 30 seconds at a time. If the
engine fails to start in 30 seconds, allow
the starting motor to cool 2 or 3 minutes and
repeat the starting operations.
5. After the engine starts, check the
engine and transmission oil pressure indi-
cators to see that they are registering pres-
ure. If either of the indicators fails to
register properly in the white area, stop
the engine and investigate the cause of the
oil pressure failure, or refer to your Inter-
tional Industrial Power distributor or
er before operating the tractor.
6. After the engine starts, check the
pressure indicator to see that it is

registering the proper pressure. If it is
not, service the diesel fuel system as
described on ra~es 65 to 67.
7. Never operate the engine under
load until it is thoroughly warmed up.
Never operate the engine at more than the
regular governed speed. Excessive speeds
are harmful.
8. When putting the tractor in motion,
always engage the engine clutch gradually
so the engine will start the tractor without
jerking. This is particularly necessary
when going up a steep hill or climbing out
of a ditch, or if the tractor is hitched to a
heavy or difficult load.
9. Do not ride the brake pedal, as this
will result in excessive wear on the linings.
10. Be sure to clean the air cleaner
(pa~e 51) and replace the lubricating oil
filter elements at regular intervals (pa~e
49) .
11. Remove and clean the filter elements
of the,transmission and planet power drive
oil filters, and of the hydraulic oil filter
(pressure line), as specified in the "LUBR f-
CATION GUIDE" 'on pages ~2 and ~3.
12. Never pour cold water into the radia-
tor if the engine is very hot, unless conditions
make it absolutely necessary. Under such .
conditions start the engine and let it idle while
slowly pouring the water into the radiator.
13. Always take the tractor out of gear
when parking the tractor. When pinking for
any length of time on a hill or slope, be sure
to lock the brake with the brake pedal lock.
