book

are

operating

and

mainte-

nance

instructions

for

the

Farmall

Cub.

This

material

has

been

prepared

in

detail

in

the

hope

that

it

will

prove

helpful

to

you

in

providing

a

better

understanding

of

the

correct

care

and

efficient

operation

of

your

tractor.

If

you

should

need

information

not

given

in

this

manual,

or

require

the

services

of

a

trained

mechanic,

get

in

touch

with

the

International

Harvester

dealer

in

your

locality.

Dealers

are

kept

informed

on

the

latest

methods

of

servicing·

tractors.

They

carry

stocks

of

IH

parts,

and

are

backed

in

every case

by

the

full facilities

of

a

nearby

International

Harvester

District

Office.

The

illustrations

in

this

manual

are

numbered

to

correspond

with

the

pages

on

which

they

appear;

for

example, I/lusts. 7

DESCRIPTION

Instruments and Controls

A variety of special

equipment

is

available for use with

the

Farmall

Cub. The instruc-

tions

Location of controls.

Brake

Pedals

These

pedals

are

used

to

stop

the

tractor,

to

hold

the

tractor

in

a

stationary

position,

or

to

assist

in

making

sharp

turns

as

outlined

below:

To

stop

the

tractor,

latch

the

pedals

to-

gether

so

both

brakes

will

operate

simul-

taneously

when

the

pedals

are

pressed

down.

To

hold

the

tractor

in

a

stationary

posi-

tion,

latch

the

pedals

together,

depress

and

lock

them

in

this

depressed

position

by

using

the

brake

pedal

lock.

To

assist

in

making·

a

sharp

turn,

the

pedals

must

be

operated

individually, de-

4

pressing

the

pedal

on

the

side

toward

which

the

turn

is

to

be

made.

The brake

pedal

latch {located

behind

the

left-

hand

brake

pedal)

is

used

to

latch

Qoth

brake

pedals

together,

causing

the

brakes

to

operate

simultane-

ously.

The brake pedal lock (Illusts. 4

and

48B) is

used

to

lock

the

brake

pedals

in

the

depressed

position.

This

prevents

the

tractor

from

!]loving.

Clutch

Pedal

This

pedal,

when

depressed

Before

Starting

Your

New

Tractor

Lubrication

Lubricate

the

entire

tractor,

using

the

"Lubrica-

tion Guide."

Check

the

oil

levels

of

the

engine

crankcase,

air

cleaner,

transmission,

belt

pulley

housing

and

all

gear

cases

to

see

that

they

are

filled

to

the

correct

levels

with

the

proper

grades

of

oil

for

the

prevailing

temperature. Refer

to

"Lubrication Guide"

and

the

specifications of lubricants

on

page

17.

Tractors shipped to destinations

in

the United States

of

America, Canada and Mexico

are

filled

with

oil

in

all

parts

before

leaving

the

factory.

Engines

·are

filled

with

a

light

engine

oil.

However,

this

is

for

·

preservative

purposes

only

and

is

not

suitable

for

regular

service.

The

original

oil

should

be

drained

from

the

crankcase

and

air

cleaner·

and

replaced

with

the

required

amount

of

fresh

oil

for

the

prevailing

temperature.

Tractors packed for export have

all

oil

drained

from

the

engine

crankcase,

air

cleaner

and

all

gear

cases.

Beforestarting the engine, for the

first

time,remove.the

spark

plugs

and

put

about

one

teaspoonful

of

crank-

case

oil

into

each cylinder;

replace

ilie

spark

plugs

and

crank

the

engine

to

distribute

the.

oil

over

the

cylinder walls;

This

assures

positive

1U:brication

of

the

cylinders

and

pistons

immediately

·~i-tet

starting

and

eliminates

the

possibility

of

scoring.

.

·,

Pneumatic

Tires

Before

moving

the

tractor,

check

the

·air_pressure

in

the

pneumatic

tires arid inflate

or

deflate,the

front

tires

to

20

lbs.

and

the

rear

tires

to

12

ibs. Refer

to

the table

on

page

.54

for

more complete information.

Engine

Cooling

System

The

cooling

system capacity is

approximately

9¾

U.S. quarts.

Be

sure

the

drain

plug

underneath

the

radiator

is closed.

See

I/lust.

26.

Fill

the

radiator

to

a level slightly belovy the

bottom

of

the

filler

neck.

Filling.

the

radiator

to

this level

will

allow

for

expansion

of

the

coolant

under

normal

.

operating

conditions.

Use

clean

water;

soft

or

water

is

recommended,

as

it

have

the

OPERATING YOUR TRACTOR

Before

attempting

to

start

or

operate

the

tractor,

be

sure

that

you

have

checked

·

over

the

instructions

for

a

new

tractor

and

thoroughly

familiarized

yourself

with

the

instruments

and

controls.

Operating the Engine

When

starting

the engine

in

a

barn

or garage, keep

the doors wide open

as

the exhaust gas from

internal-combustion engines contains poisonous

carbon m~noxide

which

is

odorless, tasteless

and

colorless.

Fuel

System

Check

the

fuel

tank

to

make

sure

it

is

full;

also

see

that

the

shut-off valve

on

the

fuel

strainer

under

the

gasoline

tank

is

open.

To

assure

against

leakage

or

seepage

when

the

valve is

in

its full-open

position,

be

sure

to

screw

out

the

needle

stem

(shut-offvalve)

until

the

seat

on

the

stem

is

tight

against

the

stop.

Be

sure

the gearshift lever

of

the

is

in

neutral

LUBRICATION

The

life

of

any

tractor

depends

upon

the

care

it

is given.

Proper

lubrication

is a very

important

part

of

that

care.

General

Engine

Lubrication

The

engine

has

a pressure-feed

lubrication

system. A gear-type

oil

pump

circulates

the

lubri-

cating

oil

under

pressure

to

the

crankshaft

bearings,

connecting-rod

bearings,

camshaft bearings, valve

mechanism,

timing

gears,

and

governor,

thereby

assuring

positive

lubrication

of

all

parts.

Oil

Pump

The

gear-type

oil

pump

in

the

crankcase

has

a

screen

attached

to

the

oil

intake

which

stops

large

dirt

particles

from

entering

the

oiling

system.

Clean this

screen

whenever

the

oil

pan

i~

removed.

Oil

Pressure

Indicator

1

The

oil

pressure

indicator

shows

whether

the

oil

pump

is

working.

_

The

oil

pressure

should

hold

the

indicator

in

the

white

section

of

the

gauge

at

approximately

100

r.p.m. above

slow

idle speed.

Should

the

indicator

not

register,

stop

the

engine

at

once

and

inspect

the

oil

system

to

find

the

cause

of

failure.

If

unable

to

find

the

cause,

consult

your

International

Harvester

dealer

before

operating

the

engine.
