LUBRICATION
Instruction on the lubrication of each assembly are given in the Lubrication Chart in the Opera-
tor's Manual. During the assembly of any parts, always coat all wearing surfaces with the lubri-
cant specified in the chart. Except for such installations as taper pins, etc. whose surfaces should
be clean and dry, use sufficient quantities of lubricant to prevent any danger of seizing, scoring
or excessive wear when the assembly is first operated. Failure to provide "starting lubrication"
may result in serious damage.
SERVICE PARTS
IH and Hough Construction Equipment deserve genuine service parts. The best material obtainable
and experience gathered through many years of manufacturing power equipment, enable Inter-
national and Hough to produce quality that will not be found in imitation or "just as good" repair
parts. No serviceman can afford to guarantee a repair job that is not serviced with genuine IH and
Hough parts. No owner should be satisfied with other than genuine parts.
For the correct service parts to be used on a machine, always refer to the Parts Catalog for that
particular machine. The loose leaf parts catalogs are accurate and are continually being brought
up-to-date by the issuance of new pages covering any changes in part numbers.
SERIAL NUMBERS
The tractor serial number plate is located on the front panel to the right of the steering column.
The IH Gasoline Engine serial number is stamped on a pad on the right hand side of the engine
block just below and to the right of the distributor.
The IH Diesel Engine serial number is stamped on a pad on the right hand side of the engine
block just to the left of the crankcase breather pipe.
The Detroit Diesel Engine serial number is attached to the rocker arm cover on top of the engine.
ENGINE
The Model H-30B PAY loader may be equipped with an IH G-263 Gasoline, IH D-236 Diesel or a
Detroit Diesel 3-53 Diesel Engine. Instructions for removal and installation of the engines are
covered in this manual. For detailed information on overhauling and adjusting the IH G- 263
Gasoline Engine and the IH D-236 Diesel Engine, refer to Service Manual ISS-1040.
WARRANTY
International Harvester and Hough make no warranty in respect to the Detroit Diesel engine in the
Model H-30B PAY loader. The engine is warranted by the Detroit Diesel Engine Division, General
Motors Corporation, Detroit, Michigan. Servicing of the engine during the warranty period is to be
handled by the General Motors Corporation distributor or dealer in your locality.

Page 4
INTRODUCTION
If detailed information on the fuel system of the IH D-236 Diesel Engine is desired, refer to the
Injection Pump Manual, ISS-1042.
SHtVICE TOOLS
The design of IH and Hough Construction Equipment machines requires a minimum of service tools
other than those in the mechanic's tool kit. Whenever the application of inexpensive special ser-
vice equipment will facilitate work, it is shown. Otherwise, it is assumed that the servicemen will
select from their tool kits as required. Information regarding special tool equipment is given in
the "Service Tool Manual" ISS-1002. The IH and Hough Construction Equipment distributors have
most of this equipment and are in an excellent position to service these PAY loaders.
GASKETS AND SEALS
Always use new gaskets and seals. When in-
stalling a leather seal, be careful to install it
as specified in the instructions. Be extremely
careful not to damage the seal in any way
during installation.
Do not "roll" and "0"- ring during installation.
To correctly install the "0"-ring, position the
ring at one point and using a blunt, narrow tool,
stretch the "0"-ring into position (refer to Fig.
I-4). Do not stretch the "0"-ring any more
than is required for proper installation.

Correct "O" -Ring Installation.
RECOMMENDED BEARING PROCEDURES
NEW BEARINGS
Keep bearings in original cartons or wrappings
until ready for use. If package is opened and
bearing is not used immediately, protect it by
re-wrapping.
Before wrapping and packing, bearings are
carefully cleaned by the manufacturer and are
thoroughly coated with a protective lubricant,
Keep bearings clean and away from moisture.
Handle bearings with clean hands and use clean
tools. Handle bearings as little as possible.
Finger marks are hard to wash off and perspir-
ation starts corrosion.
Don1t wash the oil or grease out of a new bear-
ing.
Don't take new bearings aparL They were
assembled correctly in the first place.
PRINTED IN UNITED STATES OF AMERICA

INTRODUCTION
Page 5
iEMOVAL
Wash off bearing housing; take care to prevent
loose dirt from entering the housing.
Take a few moments to study the assembly.
Determine the best way to undertake bearing
removal.
Be careful and avoid damage. The bearings
may be good enough to use again.
The best tool for removing a bearing is usually
an arbor press, Most field work however, is
done with some type of bearing puller. Where
required, this manual will refer to the correct
tool to employ. Use it for speed and safety.
To remove a bearing, press or pull only on the
race that is tight.
Press or pull straight and square to keep the
race from cocking and scoring the shaft or
damaging the bearing.
Never press or pull against bearing shields or
separators.
Keep the press table a11d support blocks clean
and square, Provide some means to keep the
shaft from falling on the floor. Protect the end
of the shaft with a pad of lead, copper or other
soft metal or a hardwood block.
Use pullers properly, Set them up so that they
will push or pull straight and square, Take care
not to damage shaft threads, keyways or
shoulders in the process.
With proper care, bearings may be removed
quite safely with improvised methods when the
right tools are not available,
A vise may do in place of an arbor press and a
drift can take the place of the press ram, If the
shaft is held in a vise, protect its surface with
copper sheet or hardwood blocks.
A suitable block, placed over the end of a tube
type driver, will allow the hammer blows to be
struck in dead center. This will prevent the
bearing from cocking.
If bearing fit does not permit the use of a bear-
ing puller or arbor press the bearing will have
to be cut ofL th( outer rnce and ball re-
tainer with an acetylene torch. Burn the inner
race only part way through. This wi.11 protect
the shaft. Crack the race the rest of the way
with a hammer and chisel, using care to pre-
vent personal injury from flying parts.
CLEANING
Don't judge the condition of a bearing until after
it has been cleaned.
Don1t spin dirty bearings. Rotate them slowly
while washing.
Don't spin any bearings with an air hose.
Rotate one race by hand, when using air, to
expose all parts of the bearing.
Bearings with a shield or seal on one side only
should be washed, inspected and handled in the
same manner as bearings without shields or
seals.
Bearings with shields or seals on both sides
should not be washed, Wipe them off to k.eep
dirt from working inside, Smooth turning bear-
ings may be coated with protective lubricant
and then wrapped and stored or used in thei.r
original application.
If a small tank and wire baskets to soak and
wash bearings are not available, a clean grease
can or bucket filled with solvent may be used.
Let the bearings soak long enough to loosen the
grease and dirt. This m.ay require several
hours or longer. Then slosh the bearing around
near the top of the container, giving it a turn
now and then untH it is clean. Rinse in a clean
container of clean solvenL
A short, clean bristle brush from which the
bristles will not come out or break off is a help
in removing dirt, scale or chips.
After bearings have been thoroughly cleaned,
inspect them immediately.

INTRODUCTION
INSPECTION
RECOMMENDED BEARING PROCEDURES
BEARING INSTALLATION
A little tarnish, stain or corrosion on the out-
side surfaces of the races is not detrimental to
the operation of the bearing and need not be
removed.
Bearings are inspected by holding the inner
race so that its axis is vertical (bearing is then
horizontal), and turning the outer race slowly.
Bearings should not be rejected because they
feel slightly rough or have a tendency to stick
at certain points when rotated by hand until the
bearings have been re- cleaned. If bearings still
feel rough and/or have a catch, inspect them
closely to determine the cause.
The following defects are common causes of
bearing rejection:
Broken or cracked races.
Dented seals or shields.
Cracked or broken separators.
Broken or cracked balls or rollers.
Flaked areas on balls, rollers or raceways.
Bearings that have been overheated. These
bearings are generally darkened to
brownish blue or blue- black color.
Bearings whose raceways are indented or
"brinelled" by ball or roller impressions
in the races.
An anti-friction bearing, properly lubricated,
should not wear unless dirt or abrasive foreign
matter gets into it. If dirt is allowed to enter a
bearing it mixes with the grease or oil and
forms a lapping compound that will quickly lap
down the balls or rollers.
The load carrying surfaces of anti-friction
bearings are finished with extreme care and
will sustain very heavy loads unless the sur-
faces are damaged by abuse in handling or by
foreign matter which may be abrasive or cor-
rosive.
Clean shafts and bearing housings thoroughly.
Remove all dirt from keyways, splines and
grooves. Remove burrs and slivers.
Clean and oil bearing seats.
Press bearings in straight and square.
Press only on the tight fitting race.
Press bearings until they are seated against the
shaft or housing shoulder.
Bearing installation is just the reverse of
bearing removal. Use an arbor press if avail-
able. Press the shaft into the bearing, support-
ing the inner race on blocks or a suitable press
adapter to prevent bearing damage. Be sure the
blocks or adapter does not scrape the shaft or
threads.
If the distance between the end of the shaft and
the bearing seat is fairly short, hold the shaft
in a vise or suitable support and press the
bearing onto the shaft with a clean tube. This
may be done either in an arbor press or by
tapping with a hammer. Cover the end of the
tube with a suitable soft metal or hardwood
block. This will allow the hammer blows to
strike the tube dead-center and avoid cocking
the bearing.
Do not leave bearings exposed in partial assem-
blies. Cover the bearings until ready to com-
plete the assembly, to prevent damage by
moisture, dirt or other foreign matter. Any
clean cloth or paper will do as long as the
bearings are well covered.
HEATING BEARINGS FOR INSTALLATION
The inner bearing race, in some applications,
may be shrunk on the shaft. This is a very
simple operation consisting of heating the
bearing in clean oil (Fig. I-5) or temperature
controlled oven to a temperature of between
200° and 250°F. This expands the inner race
sufficiently to allow it to slip over the shaft to
the bearing seat. DO NOT OVERHEAT THE
BEARING OR IT WILL LOSE ITS HARDNESS.
PRINTED IN UNITED STATES OF AMERICA

INTRODUCTION
Page 7
RECOMMENDED BEARING PROCEDURES
Do not keep the bearing in the oil or oven after
the correct temperature has been reached.
CE-95121
Figure 1-5
Expanding Bearing in Heated Oil.
If expanding the race is not enough to get it on
the shaft, freeze the shaft in dry ice for approx-
imately 30 minutes. This will shrink the shaft
and allow bearing installation.
ADJUSTMENT
Certain types of ball bearings and most dual-
purpose bearings with tapered or barrel shaped
rollers require adjustment in assembly. Speci-
fic instructions covering bearing adjustment
are contained in this manual where required.
If a bearing is set up too tight it will heat up and
fail. Loose bearings will pound and fail or cause
component parts to fail. Be sure to follow the
bearing adjustment procedures carefully.
LUBRICATION
Each assembly in this manual is supplied with
a lubrication chart that specifies the kind of
grease or oil to be used and how much. Opera-
tors Manuals specify the lubrication interval.
Follow instructions. Use only grease where
grease is specified and oil where oil is speci-
fied. Be sure to use exactly the kind of lubricant
the instructions call for.
Store grease in clean containers. Handle grease
with clean paddles or grease guns. Keep grease
containers covered.
Don't overfill. Grease or oil will ooze from
overfilled housings past seals and closures,
collect dirt and thereby lay the groundwork for
bearing failure. Too much lubricant will also
cause overheating. This is particularly true of
bearings running at high speeds where the
churning of the lubricant will cause the bearings
to run excessively hot.
Don't let any machines stand idle for months
without turning it over once in a while so that
bearing surfaces will be covered with lubricant.
Oil tends to drain down off a standing bearing.
Moisture condensing in the housing is then free
to corrode the un-coated bearing.
Be sure to inspect seals and vents regularly.

INTRODUCTION
LOCTITE AND LOCQUIC DATA
LOCTITE
Loctite is a lock or seal for metal parts. It is
furnished as a liquid plastic. Contact with air
keeps it liquid. When confined between mating
parts, the exclusion of air causes the liquid
Loctite to set by chemical action.
LOCQUIC
Locquic is a priming rinse used to speed the
setting of the Loctite sealant and also must be
used on zinc or cadmium plated parts for sur-
face preparation to enable the Loctite sealant
to completely set. Locquic Grade "Q" is avail-
able in six ounce pressure spray cans.
Use Loctite Grade "B" (yellow color) on all
threaded connections with the exception of the
following:
L Exhaust pipe mounting hardware.
2. Elastic stop nuts.
3. When lock washers are used.
4. When bolt or nut retaining lock plates
are used.
5. On items requiring frequent service (500
hours or less), such as filler caps, adjusting
screws, wheel stud clamp retaining nuts, etc.
6. On brass pipe plugs and fittings in air
systems and all other pipe fittings.
7. All stud applications.
PART PREPARATION FOR LOCTITE
PLAIN, PHOSPHATE COATED, OR PLATING
OTHER THAN ZINC OR CADMIUM: Clean the
surfaces where Loctite is to be applied to
remove heavy coating of oil, grease and dirt
(rust or light oil film are not detrimental),
Normal shop practice of cleaning or degreasing
is adequate. Allow surface to dry before apply-
ing Loctite. Care must be used on blind tapped
holes to remove chips and oil.
ZINC OR CADMIUM PLATED PARTS OR FOR
QUICK SETTING: To assure setting of Loctite
on zinc or cadmium surfaces and quick setting
on other surfaces at least one of the mating
surfaces should be sprayed with Locquic Grade
"Q. " Locquic Grade "Q" is an effective rinse
for oily parts. Allow surfaces to dry before
applying Loctite Grade "B" sealant.
LOCTITE APPLICATION
BOLT THREADS: Fill the first two or three
leading threads in area of engagement with
Loctite Grade "B. "
PIPE THREADS: Use Loctite pipe sealant.
ALL STUD APPLICATIONS: Use Loctite plastic
gasket.
SETTING
NORMAL TIME: Three to four hours.
WITH LOCQUIC GRADE "Q": Fifteen minutes.
REMOVAL
Parts difficult to remove can be pre- heated to
approximately 500° prior to removal.

GENERAL SAFETY PRECAUTIONS
A deal of material contained in this serv-
ice ffv,m1.ml concerns itself with the removal
and installaUon of exceptionally heavy items.
the time these operations are being
carri.ed out, safe working conditions and pro-
cedm:es are mandatory, to not only insure
safety but the safety of others in the
aTea, The following items are listed as a
;:c::n1bder of basic shop safety practices, too
often ~wglected in day-to-day operation.
rcotsts n1·1c:t be of sufficient capacity to lift
the he;;rder units (i.e. engine, grille, fuel
have an ample safety margin.
;Je clean and dry. After draining
be sure all spillage is cleaned up.
c.orcds and wet floors make a
·:rn1bfnation.
sturdy step ladders to mount and dis-
n.t0lff1t from the engine compartment; do not
clt.'11b on tireso
Be sure items are properly supported
hoist or floor jack before removing
rr,embers from tractor.
Have sufficient service personnel available
when removing or installing large heavy items
in order to maintain control at all times.
If a heavy item begins to fall, let it fall; don't
try to catch it.
Bucket and/or boom must be resting on ground
at all times during machine servicing and
periods of idleness.
Do not start an engine indoors unless adequate
exhaust ventilators are provided. Once an
engine is running, move the machine outdoors
as soon as possible. Be sure air pressure is
sufficient to provide positive brake application.
Keep hands, feet, clothing away from rotating
engine parts.
As a machine is being moved, the operator
must face the direction of travel.
Think before you act. Carelessness is one
luxury the serviceman cannot afford.
