DESCRIPTION

MAINCOMPONENTS

The TD-I4A Crawler Tractor is a full

track-laying type tractor. The principal com-

ponents of the tractor are the engine, engine

clutch, transmis sion, steering clutches,

sprocket drives and track assemblies.

Diesel Engine

Engine power is supplied by a full diesel,

four-cylinder in-line engine. Features of the

engine are; a five-bearing, Tocco-hardened

crankshaft, replaceable cylinder sleeves, pre-

cision-type bearings, full pressure lubrication

system, and a thermostat-controlled, centri-

fugal water pump cooling system.

Engine Clutch

The engine clutch is a heavy-duty, IS-inch,

single-plate, hand-operated, over-center type.

The release mechanism has an automatic clutch

brake to facilitate fast shifting of gears.

Transmission

The transmission is the selective spur-

gear type providing six forward speeds and two

reverse speeds.

There are three forward and one reverse

speeds in the low range, and three more for-

ward and one reverse in the high range. Shift-

ing from one range to the other is controlled by

the Hi-Lo gearshift lever.

The gearshift lock provides positive hold-

ing of the sliding gears of the transmission and

is ideal for operation under heavy load condi-

tions and frequent gear shifting.

Steering Clutches and Brakes

Steering is accomplished through two

multiple dry-disc, spring-loaded steering

clutches by means of the two spring booster

hand operated steering levers.

Steering brakes, operating on the steering

clutch drums, make very sharp turns possible.

The steering clutches transmit engine power

from the bevel gear out to the sprocket drives.

These clutches, with brakes, can be adjusted or

replaced without disturbing adjacent units.

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 and sprockets are ball-bearing

mounted on the stationary pivot shaft.

Sprockets are reversible, making

possible

to use both sides of the teeth.

Track Assemblies

Track assemblies consist of track chains

and shoes driven by sprockets. The chains

travel forward over two track idlers and

around the front idlers. Five track rolle;rs

on the bottom of each track frame carry the

weight of the vehicle. Sprockets and idlers

are also mounted on the welded channel-iron

track frames.

DruSEL FUEL SPECIFICATIONS

The best guide to follow when selecting

fuel for use in the International diesel engine

is the set of fuel specifications prepared and

recommended by the builder.

Most refiners now market fuel oil desig-

nated 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 con-

tain sufficient quantities of the lower ignition

catalytic crack/ed distillates to make it unsatis-

factory for use in the International diesel engine.

Some refiners are marketing one grade of

fuel for both diesel and burner use. This fuel,

when within the specifications shown below, can

be safely used. However, maintaining the

quality and suitability of these fuels for Inter-

national diesel engines is definitely the respon-

sibility of the supplier.

Diesel fuel for high-speed diesel engines'

is now obtainable in the U.S.A. in two grades,

namely No. l-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 specifications on the next page:

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 lower viscos-

ity. Its use may result in loss of power and/or

increased fuel consumption and shortened in-

jection pump life. However, No. I-D fuel may

be required in sub-zero weather in order for

the pump

maintain an adequate flow of fuel.

Fuels lighter than kerosene will not give

satisfactory performance in International

diesel engines. Although some fuels meet the

No. 2-D specifications, their composition may

be such that unsatisfactory engine wear and ex-

cessive deposits may result unless high addi-

tive lubricating oil is used. Knowledge of the

fuels in your area and the types of crankcase

oils required for satisfactory performance with

these fuels will avoid service problems. When

in doubt, see your International Industrial

Power distributor or dealer.

Water and sediment will tend to clog the

filters.

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 be-

cause the fuel is less likely to become con-

taminated. 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 re-

duce condensation. Drain the water trap daily.

Following these rules will pay dividends.

OPERATION

BEFORE STARTING A NEW TRACTOR

1. Make a complete inspection of the

tractor for any damage that may have occurred

while in transport. Check to be sure that all

component units are securely mounted to the

engine.

Refer to the "LUBRICATION GUIDE"

and

completely lubricate the tractor, including the

air cleaner.

a. Tractors shipped to destinations in the

United States, Canada and Mexico are filled

with oil before leaving the factory. The lubri-

cant in the crankcase, air cleaner and injection

pump of diesel engines, when shipped from the

factory, is for snipaway purposes and is not

suitable for use in regular service. The ori-

ginal oil should be drained immediately from

the crankcase, air cleaner and injection pump

and replaced with the required amount of

fresh oil having the physical properties and

proper viscosity for the prevailing air temper-

atures and type of service.

h. All oil is drained from the crankcase

and air cleaner of tractors shipped for export.

3. Check to be sure that the drain valve

on the lower left side of the radiator is closed

and that the drain valve on the left side of the

crankcase is closed. Fill the cooling system

with clean water (soft or rain water

pos-

sible) to a level slightly below the bottom of

the radiator filler opening.

4. Check the tension of the fan belts. The

tension is correct when the belt can be de-

pressed by thumb pressure 3/4 to I inch mid-

way between two pulleys.

the belt tension is

not correct, adjust

outl tned on pa~e 43.

5. If the tractor is equipped with a start-

ing attachment, be sure that the battery cable

terminal is clean and bright; then connect the

braided ground strap to the battery,

Illust.

Connect the generator field cable to the "F"

terminal on the generator,

Illust.

4. Cor-

rectly polarize the generator to the battery by

placing a jumper lead momentarily across the

"BAT" and "GEN" terminals of the generator

relay. Check to be sure that all electrical

terminals are clean and securely fastened.

Check the level and the specific gravity of

electrolyte in the batteries.

Illust.3

Battery and battery cables.

Check to be sure that the magneto is

securely mounted in place and that it was not

damaged or cracked in shipment. Check the

spark plug cables to be sure that they are se-

cure1y connected in the magneto distributor

cap and at each spark plug.

Illust. ~

connected to terminals.

OPERATING CONTROLS AND

INSTRUMENTS

The operator should be thoroughly

familiar with the location and the use

of all controls and instruments on the

tractor before trying to operate

it.

Re-

gardles s of previous experience as a

tractor operator, carefully read this

section before attempting to operate

the tractor.

Compression Release Lever

This is a short lever located in

the upper left corner of the dash.

See

Illust.

6. Pulling down on this lever

converts the engine from the diesel to

the gasoline cycle for starting pur-

poses. When placing the compression

release lever in the gasoline position,

be sure

latches securely. After the

engine has operated on gasoline for

about one minute

minutes for

severe cold conditions), switch the

engine to diesel operation by pushing

the compression release lever all the

way up. Leave the compression re-

lease lever in the diesel position (up

position) after the engine has stopped.

The choke lever assists in starting the en-

gine when the engine is cold. Turning the

choke lever clockwise shuts off the air to the

carburetor, giving a rich mixture. After the

first few revolutions of the engine, turn the

choke lever counterclockwise

a point where

the engine operates without missing. After

the engine has operated a short time, turn the

choke lever counterclockwise all the way.

set in a given position, maintains a uniform

engine speed under variable loads. Moving

the lever upward increases the engine speed,

and moving it downward decreases the engine

speed.

Engine Clutch Hand Lever

This is the long lever extending up from

the left side of the platform in the operator's

compartment.

See Illust.

is used to en-

gage or disengage the engine from the trans-

mission. Pull the lever all the way back, or

until a definite over-center action is felt, to

engage the clutch, and push the lever all the

way forward to disengage the clutch.

Gearshift Lever

This is the short lever extending at an

angle from the gearshift housing in the oper-

ator's compartment.

See Illust.

is used

to select the various gear ratios provided in

the transmission. There are three forward

speed positions and one reverse speed posi-

tion. A total of six forward speeds and two

reverse speeds is available by using the Hi-Lo

gearshift lever.

The gearshift lock provides positive hold-

ing in engagement of the sliding gears on the

transmission.

heavy load conditions and frequent gear shift-

ing.

Hi-Lo Gearshift Lever

It is the short lever located directly to the

left of the transmission gearshift lever.

See

Illust.

controls the high and low speed

range of the transmission. When the lever is

in the downposition (forward), the transmis-

sion gearshift lever can be used to select low

speeds in reverse, first, second and third

gear. When the lever is moved to the up po-

sition (backward), the tractor can be shifted

high speeds in reverse, fourth, fifth and

sixth gears.

Steering Clutch Hand Levers

These are the two long hand levers located

directly in front of the tractor seat on either

side of the transmission gearshift lever.

See

Illust.

6. Pulling back on the left lever dis-

engages the left steering clutch which cuts

off power going to the left track. All of the

engine power is then applied on the right track,

causing the tractor to turn to the left. Pull-

ing back on the right lever causes the tractor

to turn to the right. A minimum of effort is

required to operate the spring booster, hand

operated levers.

Steering Brake Pedals

These are located on either side of the

operator's compartment, coming up through

the platform.

See Illust.

6. Normally, when

pulling a load the use of the steering clutch

levers will turn the tractor. Steering brakes

are used to make sharp pivot turns. To make

a sharp turn, pull all the way back on the

steering clutch lever and press down the steer-

ing brake pedal on the side toward which the

turn is to be made.

Steering Brake Locks

The locks are located underneath each

steering brake pedal.

See Illust.

6. To lock

either brake, push down the pedal and raise

the lock rod. This action engages a pawl in

a ratchet on the pedal and locks the brake.

To unlock the brake's, push downon the pedals

and release the lock rods.

Oil Pressure Indicator

is located in the upper right corner of

the dash in the operator's compartment and

it indicates the pressure of the oil circulating

through the engine.

See Illust.

8. The in-

dicator needle must be in the white sector of

the gauge when the engine is operating and oil

pressure is normal.

the indicator needle

remains in the red sector, stop the engine

immediately and investigate the cause of oil

pressure failure.

you are unable to find

the cause, consult your International Industrial

Power distributor or dealer before operating

the engine.

Ammeter

This instrument (part of the starting and

lighting attachments) is located in the upper

right corner of the dash, just

the left of the

oil pressure gauge.

See Illust.

Choke Button

This button (part of the starting and light-

ing attachment) is located in the right-hand

portion of the dash in the operator

s compart-

ment.

See III ust ,

8. The choke aids in start-

ing the engine when it is cold. Pulling out the

choke rod restricts the flow of air to the car-

buretor, enriching the fuel mixture. After the

first few revolutions of the engine, push the

choke button in half way, or to a point where

the engine runs without missing. As the en-

gine gradually warms up, push the choke

button all the way in.

Electric Starter Button

This button (part of the starting and light-

ing attachment) protrudes from the dash at a

point directly above the right-hand steering

brake pedal.

See III ust.

8. Depres sing this

button completes the electrical circuit between

the battery and the cranking motor, and causes

the cranking motor pinion to engage the flywheel

ring gear, thereby cranking the engine. Stop

pressing the button the moment the engine

starts. Donot operate the cranking motor for

more than 30 seconds at anyone time. Allow

the cranking motor to cool 2 or 3 minutes and

repeat the starting operations.

Primer Button (Special)

is located directly to the right of the

choke button.

Se(3 Illust.

8. When starting the

engine in cold weather, the engine should be

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 upon the tem-

perature.

OPERATING PRECAUTIONS

NOTE:Operate a new tractor with a light

load for the first 30 to 36 hours at a governed

speed from 1450 to 1500 rpm.

1. Do not attempt to start the engine by

towing or coasting the tractor. To do so may

cause serious damage to the engine and trans-

mission.

2. Do not run the cranking motor (special

attachment) for more than approximately 30

seconds at anyone time.

the engine fails to

start, allow the cranking motor to cool for 2

or 3 minutes and then repeat the starting

operation.

trouble is experienced in starting on

gasoline in cold or damp weather, the spark

plugs should be removed and wiped off, re-

moving any condensation. At the same time,

check the spark plug gap, which should be

.023 inch. After drying the spark plugs, in-

stall them in the engine: then start the engine

in the usual manner.

4. When cranking the engine by hand,

stand in a position that will eliminate any pos-

sibility of being struck by the starting crank

there is a reversal of the direction of the en-

gine.

See Illust.

19. Crank the engine by using

quick upstrokes; do not spin it.

5. CAUTION:Never fill the gasoline tank

when near an open flame, or when the engine

is operating. Keep the funnel, used for pour-

ing in the fuel, in contact with the metal of the

tank. By so doing, you will avoid the possi-

bility of an electric spark igniting the gas. Do

not light matches near gasoline as the air

within a radius of several feet is permeated

with a highly explosive vapor.

See Illust. 14;

Illust. IlJ

Correct method of

pouring gasol ine into the tank.

6. Be sure that the vent holes in the caps

for the fuel and gasoline tanks are kept open

at all times to assure proper flow of the fuel.

See Illust.

15.

7. Do not 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

pouring the water slowly into the radiator.

8. Do not apply the steering brake until

the steering clutch is fully released as exces-

sive heating and rapid wear of steering brakes

will result.

9. When pulling a load, it is not necessary

to use the steering brakes except to make

sharp tur'ns ; the load acts as a brake. Do not

use the brakes unless it is necessary to do so

in order to make the required turn.

will result in excessive wear on the brake

linings.

11.

Improper use of the steering brakes

when making turns will cause the tractor to

jerk. Try to avoid this by using the steering

control lever intermittently with only a slight

pressure on the brake pedal when making any

turn except a pivot turn. This method of turn-

ing gives you a more even turn and does not

subject the tractor to sudden impacts.

12.

The drawbar should be free to swing

at all times unless it is absolutely necessary

hold it in one position.

13.

Place the transmission gearshift lever

into the desired speed position before putting

the tractor into motion.

14.

Do not operate the engine under load

until it 'is thoroughly warmed up. Never op-

erate the engine at more than the regular

governed speed. Excessive speeds are harm-

ful.

16. Be sure to replace the lubricating oil

filter element and to clean the air cleaner at

the regular specified intervals.

CAUTION:

Because of fire hazards and in-

surance regulations, we do not recommend the

use of gasoline for the cleaning of parts, es-

pecially not when service is performed inside

of buildings. A less inflammable fluid than

gasoline should be used, such as Stoddard sol-

vent or kerosene.

OPERATING

THE DIESEL ENGINE

Four steps are necessary in operating this

diesel engine:

Starting the engine on gasoline.

Changing to diesel operation.

Changing the engine back to gasoline

operation before stopping the engine. This

facilitates the next starting.

After stopping the engine on gasoline,

push the compression release lever up into

diesel position. This action permits the start-

ing valves to coolon their seats.

The above steps are fully explained in the

following pages.

Shifting Gears

Always completely disengage the engine

clutch when shifting gears. To disengage the

engine clutch push the engine clutch hand lever

all the way forward. This action disengages

the clutch and applies the clutch brake in the

same operation. To shift gears, apply forward

pressure on the clutch hand lever and, at the

same time, move the transmission gearshift

lever

the correct position for the speed de-

sired.

See I

tuet; 21.

OPERATION

Engine Clutch Brake

The clutch brake

(see Illust.

22)

consists

of a stationary disc that is actuated by the

clutch release mechanism, and a disc with

frictional facing that is attached to the clutch

release bearing carrier. Forward pressure

on the clutch hand lever forces the stationary

disc into contact with the spinning friction disc

and slows down the speed of the clutch shaft.

This action in turn slows down the revolu-

tions of the transmission gears and allows

faster shifting. No adjustment of the clutch

brake is necessary.

Hi-10 Gearshift Lever

The high and low speed range of the trans-

mission is corrtr-oIled by the Hi-Lo gearshift

lever.

See Illust.

20.

Moving this lever for-

ward places the transmission in the low speed

range, and moving it backward selects the high

speed range.

When the Hi-Lo lever is in the

"down"

po-

sition (forward), the tractor can be shifted, by

using the transmission gearshift lever, into

low-reverse, first, second or third speeds.

When the Hi-Lo lever is in the "up" position

(backward), the tractor can be shifted to high-

reverse, fourth, fifth or sixth speeds.

Steering the Tractor

The direction of travel of the tractor is

controlled by two steering clutch levers.

1. Turn

the right or left by pulling back

the steering clutch lever on the side toward

which the turn is

be made.

2. To make a sharp turn, use the steering

brake on the side toward which the turn is to be

made'. For example: To turn sharply to the

right, pull back on the right steering clutch

lever and then push down on the right steering

brake pedal.

See Illust. 23.

pulling back on the steering clutch

lever does not turn the tractor enough, and

pushing the steering brake all the way down

turns the tractor too much, press down gently

on the steering brake pedal until the desired

turn is made.

Steering Downgrade

1. When going downgrade with the tractor

pulling the load, stee:-ing ~hould be done in the

usual manner.

2. When going downgrade with the load

pushing the tractor, the steering clutch op£ra-

tion is reversed. Disengage the right steering

clutch to turn left, and disengage the left steer-

ing clutch to turn right. Do not apply the

brakes.

Operating Over an Obstruction

When driving over a log or ditch bank, use

the steering clutches instead of the engine clutch

to the tractor. Both steering clutches may be

released slightly until the tractor moves for-

ward at an angle, over and down.

the load

is light, it might be necessary to use the

brakes.

Steering Brake Locks

Each steering brake pedal has a locking

device. To lock either brake, push the brake

pedal down and lift up the ratchet pawl,

Illust.

24.

This engages the pawl in the ratchet and

locks the brake pedal.

OPERATION

Do not use the brake pedals as footrests;

this would cause undue wear on the brake parts.

Illust. 2~

Left brake pedal in locked position.

Stoppingthe Tractor

Push the engine clutch hand lever all the

way forward to disengage the engine, and move

the transmission gearshift lever into neutral

position.

necessary, push down on both

steering brake pedals to halt the tractor.

the tractor is to be parked on a slope

where there is a possibility of rolling, apply

the brakes and lock them by raising the brake

locks.

NOTE::

the tractor is to be parked on a

slope during extremely cold weather, secure

the tractor with blocks instead of locking the

brakes. Condensation of moisture may cause

the brake bands to freeze on the drwns.

Stoppingthe Engine

I. Turn on the gasoline supply by opening

the shut-off valve.

2. Place the engine speed control lever in

the starting (shut-off) position and at the same

time place the compression release lever in

the gasoline (starting) position.

3. Allow the engine to operate on gasoline

until the exhaust is clear; then stop the engine

by placing the compression release lever in

the diesel position (do not move the engine

speed control lever).

4. After the engine stops, leave the com-

pression release lever in the diesel position to

permit the starting valves to coolon their seats.

5. Close the gasoline shut-off valve.

Towinga Disabled Tractor

At times it may be necessary to tow the

tractor. However, if the power train or the

tracks are damaged, the tractor should be

transported to avoid further damage. To tow

a tractor:

Attach a towing cable to the front of the

tractor or, in an emergency, to the drawbar.

2. Be sure that the steering brakes are re-

leased before towing the tractor.

3. Use the steering clutch hand levers to

assist in steering the towed tractor.

4. Never tow the tractor when the tracks

are damaged.

OPERATING

IN COLD WEATHER

order to start and operate the tractor

with a minimum of difficulty in temperatures

of 32°F. or lower, observe the following pre-

cautions:

Starting the Engine

lust. 25

Priming the engine when starting.

Continued on next pa~e

OPERATION

During cold weather, and when the engine

is cold, set the choke lever nearly closed and

prime the engine with the primer button,

equipped with primer attachment. In zero

weather, give the engine 6 to 8 primes.

In temperatures 10

to 20

F., give the

engine 3 to 5 primes.

In temperatures 30

to 40

F., give the

engine 1 to 3 primes.

Then crank the engine in the usual manner.

Fuel System

Use only a high=tes

winter-grade gaso-

line for starting. Keep the supply in a closed

container to prevent the more volatile portion

of the gasoline from evaporating. Fill the

gasoline tank and the diesel fuel tank at the end

of each day

s run to prevent moisture from

collecting in the tanks.

Lubricating the Tractor

Lubricate the tractor completely with

winter-grade lubricants

as outl ined in the

"LUBRICATION GUIDE" on pages 2~ and 25.

Cooling System

When the temperature is likely to be 32°F.

or lower, there is danger of the water freezing

in the cooling system. To prevent this, either

drain the water from the cooling system at the

end of each run, or use a recommended anti-

freeze solution.

IMPORTANT!

Before filling the radiator in

freezing weather, cover the entire radiator

and start the engine; then put in the water

IMMEDIATELY.

This prevents the water from

freezing during the warming up period.

NOTE:

Never operate the engine without

water or antifreeze solution in the cooling sys-

tem. Do not start a cold engine and operate

dry while driving the tractor to the source of

the coolant.

This is most apt to cause cyl inder

head failure, overheat the piston rings and (in

wet sleeve engines) destroy the rubber seal

ring. Carry the water t9 the tractor.

The capacity of the cooling system is 19

gallons.

the tractor is equipped with a

radiator shutter and heat indicator, close the

shutter when starting; then regulate it as re-

quired to hold the needle of the heat indicator

in the high side of the "RUN" range.

Using Antifreeze Solutions

The table below shows the amount of anti-

freeze solution required for various temper-

atures.

NOTE:

Use only one type of antifreeze solu-

tion. Do not mix solutions, as this would make

it difficult to determine the amount of protec-

tion given to the cooling system.

Never use any of the following as an anti-

freeze in the cooling system: Honey, salt,

kerosene, diesel fuel, glucose or sugar,

calcium chloride, or any alkaline solution.

Do not use alcohol as an antifreeze if other

solutions are available, as denatured alcohol

boils at 173

F. However, if it is necessary

to use alcohol, the use of a low boiling point

thermostat is recommended.

See "SPECIAL

ATTACHMENTS" section.

Check the solution fre-

quently to be sure that the cooling system is

adequately protected against freezing.

Servicing the Batteries

(If

Tractor is

Equipped with Starting and Lighting

Attachment)

The efficiency of batteries decreases

sharply with lowering temperatures and

be-

comes practically nil at minus (-) 40

F. Do

not attempt to start the engine, if the batteries

have been chilled to _20

F., unless the bat-

teries have been heated. Immersion in warm

water to within an inch or two of the top of the

battery case is a satisfactory means of warm-

ing a battery. Check the specific gravity of

the battery electrolyte at frequent intervals,

and keep the batteries as fully charged as

possible.

Checking the Spark Plugs

trouble is experienced in starting, re-

move the spark plugs and wipe them off to re-

move any condensation. Then check the spark

plug gap, which should be .023 inch.
