INTRODUCTION

Machine start-up.

• Never run the engine in confined spaces that are not equipped with adequate ventilation for exhaust gas extraction.

• Never place the head, body, limbs, feet, hands or fingers near rotating and moving parts.

Hydraulic systems and fuel injection systems

• A liquid leaking from a tiny hole may be almost invisible but, at the same time, be powerful enough to penetrate

the skin. Therefore, NEVER USE HANDS TO CHECK FOR LEAKS but use a piece of cardboard or paper for this

purpose. If any liquid penetrates skin tissue, call for medical aid immediately. Failure to treat this condition with

correct medical procedure may result in serious infection or death.

• In order to check the pressure in the system use suitable instruments.

Wheels and tires

• Make sure that the tires are correctly inflated at the pressure specified by the manufacturer. Periodically check the

rims and tires for damage.

• Stand away from (at the side of) the tire when checking inflation pressure.

• Do not use parts of recovered wheels as incorrect welding brazing or heating may weaken and eventually cause

damage to the wheel.

• Never cut or weld a rim mounted with an inflated tire.

• Deflate the tire before removing any objects that may be jammed in the tire tread.

• Never inflate tires using inflammable gases, as this may result in explosions and injury to bystanders.

Removal and installation

• Lift and handle all heavy parts using suitable hoisting equipment. Make sure that parts are sustained by appropriate

hooks and slings. Use the hoisting eyebolts for lifting operations. Extra care should be taken if persons are present

near the load to be lifted.

• Handle all parts carefully. Do not put your hands or fingers between parts. Wear suitable safety clothing - safety

goggles, gloves and shoes.

• Avoid twisting chains or metal cables. Always wear safety gloves when handling cables or chains.

• Damaged or bent chains or cables are unreliable. Do not use them for lifting or towing. Always use suitable pro-

tective gloves when handling chains or cables.

• Chains should always be safely secured. Make sure that the hitch-up point is capable of sustaining the load in

question. Keep the area near the hitch-up point, chains or cables free of all bystanders.

• Metal cables tend to fray with repeated use. Always use suitable protective devices (gloves, goggles, etc.) when

handling cables.

SHIMMING

For each adjustment operation, select adjusting shims and measure individually using a micrometer, then add up

the recorded values. Do not rely on measuring the entire shimming set, which may be incorrect, or the rated value

indicated on each shim.

ROTATING SHAFT SEALS

For correct rotating shaft seal installation, proceed as follows:

• before assembly, allow the seal to soak in the oil it will be sealing for at least thirty minutes

• thoroughly clean the shaft and check that the working surface on the shaft is not damaged

• position the sealing lip facing the fluid; with hydrodynamic lips, take into consideration the shaft rotation direction

and position the grooves so that they will deviate the fluid towards the inner side of the seal

• coat the sealing lip with a thin layer of lubricant (use oil rather than grease) and fill the gap between the sealing lip

and the dust lip on double lip seals with grease

• insert the seal in its seat and press down using a flat punch, do not tap the seal with a hammer or mallet

• whilst inserting the seal, check that it is perpendicular to the seat; once settled, make sure that it makes contact

with the thrust element, if required

• to prevent damaging the seal lip on the shaft, position a protective guard during installation operations

O-RING SEALS

Lubricate the O-RING seals before inserting them in the seats, this will prevent them from overturning and twisting,

which would jeopardise sealing efficiency.

SEALING COMPOUNDS

Apply one of the following sealing compounds on the mating surfaces marked with an X: RTV SILMATE,

RHODORSIL CAF 1 or LOCTITE PLASTIC GASKET. Before applying the sealing compound, prepare the surfaces

as follows:

• remove any incrustations using a metal brush

• thoroughly de-grease the surfaces using one of the following cleaning agents: trichlorethylene, petrol or a water

and soda solution

COTTER PINS

When fitting split cotter pins, ensure that the pin notch is positioned in the direction of the force required to stress the

pin. Spiral cotter pins do not require special positioning.

INTRODUCTION

PROTECTING THE ELECTRONIC/ ELECTRICAL SYSTEMS DURING CHARGING OR WELD-

ING

To avoid damage to the electronic/electrical systems, always observe the following:

1. Never make or break any of the charging circuit connections, including the battery connections, when the engine

is running.

2. Never short any of the charging components to ground.

3. Always disconnect the ground cable from the battery before arc welding on the combine or on any header

attached to the combine.

• position the welder ground clamp as close to the welding area as possible

• if welding in close proximity to a computer module, then the module should be removed from the combine

• never allow welding cables to lay on, near or across any electrical wiring or electronic component while welding

is in progress

WARNING

Battery acid causes burns. Batteries contain sulfuric acid.

Avoid contact with skin, eyes or clothing. Antidote (external): Flush with water. Antidote (eyes): flush

with water for 15 minutes and seek medical attention immediately. Antidote (internal): Drink large

quantities of water or milk. Do not induce vomiting. Seek medical attention immediately.

Failure to comply could result in death or serious injury.

W0111A

Always use the jump stud posts installed on the machine to jump start the machine or to charge the batteries.

Refer to the Operator's Manual for more information!

NOTICE: If welding must be performed on the unit, either the combine or the header (if it is attached), the battery

ground cable must be disconnected. The electronic monitoring system and charging system will be damaged if this

is not done. Refer to the Operator's Manual for more information!

Remove the battery ground cable. Reconnect the cable when welding is completed.

General information

• Hydraulic connections require a minimum assembly torque in order to provide zero leakage at rated pressure with

adequate fatigue resistance. Over-torquing of a hydraulic connection can also lead to leakage or failure. For some

connections, NEW HOLLAND requires a different torque value than is listed in the ISO and SAE standards.

• The torque values in this document should be used whenever possible or applicable.

NOTICE: Always follow the instructions in this manual for specific torque values when you service components.

The information in this section is for general guidance only when a procedure contains no specific torque value.

Tolerance

• The tolerance for all torque values is ± 10 %. This tolerance must include all assembly variation, not only the torque

wrench repeatability.

Lubrication

Application of grease or other lubricants to hydraulic connectors should be avoided. If clean hydraulic oil is already

on the connection, it is not required to remove the oil. Generally, application of grease:

• May cause a significant change in the torque required to properly tighten the connection.

• May reduce the connection’s resistance to vibration.

• Excessive grease may displace an elastomer seal during tightening.

• Grease extrusion when connection is tightened may be mistaken for leakage.

NEW HOLLAND products generally use O-Ring Boss (ORB) connectors that have Teflon™-coated O-rings, eliminat-

ing the need for O-ring lubrication during installation. For connections which are made into aluminum manifolds or

with stainless steel connectors, it may be required to apply a lubricant to prevent galling.

Use of LOCTITE® and other thread-locking compounds is prohibited. These compounds:

• May cause a significant change in the torque required to properly tighten the connections.

• Reduce the serviceability of the joint.

• May prevent the O-ring from properly sealing if the compound gets on the O-ring.

Chain Wear

The individual joints in a roller chain articulate as they enter and leave the sprockets. This articulation results in wear

on the pins and bushings. A material is worn away from these surfaces the chain will gradually elongate.

ZEIL10GH0003A0B

Chains do not "stretch" - material is removed from pin and bushing.

(1):

2x pitch

(2):

2x pitch + wear

(3): elongation due to pin and bushing wear.

Elongation is normal and may be minimized by proper lubrication and drive maintenance. The rate of wear is depen-

dent upon: the relationship between the load and the amount of bearing area between pin and bushing, the material

and surface condition of the bearing surfaces, the adequacy of lubrication and the frequency and degree of articulation

between pins and bushings.

The latter is determined by the quantity of sprockets in the drive, their speeds, the number of teeth and the length of

the chain in pitches.

ZEIL10GH0015A0A

Measurement of Chain For Wear Elongation

Relatively accurate wear measurements can be made by using the above illustration. Measure as closely as possi-

ble from the center of one pin to the center of another. The more pitches (pins) contained within the measurement

increase the accuracy. If the measured value exceeds the nominal by more than the allowable percentage the chain

should be replaced.

The maximum allowable wear elongation is approximately 3 % for most industrial applications, based upon sprocket

design. The allowable chain wear in percent can be calculated using the relationship: 200/ (N), where (N) is the

number of teeth in the large sprocket.

47956065 17/05/2016

INTRODUCTION

This relationship is often useful since the normal maximum allowable chain wear elongation of 3 % is valid only up to

67 teeth in the large sprocket. In drives having fixed center distances, chains running in parallel or where smoother

operation is required, wear should be limited to approximately 1.5 %.

For example, if 40 pitches (40 pins) of a #40 chain were measured and the result was 523 mm (20.6 in) or greater

(using 3 % as the maximum allowable wear), the chain should be replaced. Anything less than 523 mm (20.6 in)

would still be acceptable by most industrial standards.

Shimming

For each adjustment operation, select adjusting shims and measure the adjusting shims individually using a microm-

eter, then add up the recorded values. Do not rely on measuring the entire shimming set, which may be incorrect, or

the rated value shown on each shim.

Rotating shaft seals

For correct rotating shaft seal installation, proceed as follows:

1. Before assembly, allow the seal to soak in the oil it will be sealing for at least thirty minutes.

2. Thoroughly clean the shaft and check that the working surface on the shaft is not damaged.

3. Position the sealing lip facing the fluid.

NOTE: With hydrodynamic lips, take into consideration the shaft rotation direction and position the grooves so that

they will move the fluid towards the inner side of the seal.

4. Coat the sealing lip with a thin layer of lubricant (use oil rather than grease). Fill the gap between the sealing lip

and the dust lip on double lip seals with grease.

5. Insert the seal in its seat and press down using a flat punch or seal installation tool. Do not tap the seal with a

hammer or mallet.

6. While you insert the seal, check that the seal is perpendicular to the seat. When the seal settles, make sure that

the seal makes contact with the thrust element, if required.

7. To prevent damage to the seal lip on the shaft, position a protective guard during installation operations.

O-ring seals

Lubricate the O-ring seals before you insert them in the seats. This will prevent the O-ring seals from overturning and

twisting, which would jeopardize sealing efficiency.

Sealing compounds

Apply a sealing compound on the mating surfaces when specified by the procedure. Before you apply the sealing

compound, prepare the surfaces as directed by the product container.

Spare parts

Only use CNH Original Parts or NEW HOLLAND Original Parts.

Only genuine spare parts guarantee the same quality, duration, and safety as original parts, as they are the same

parts that are assembled during standard production. Only CNH Original Parts or NEW HOLLAND Original Parts can

offer this guarantee.

When ordering spare parts, always provide the following information:

• Machine model (commercial name) and Product Identification Number (PIN)

• Part number of the ordered part, which can be found in the parts catalog

INTRODUCTION

Protecting the electronic and/or electrical systems during charging and welding

To avoid damage to the electronic and/or electrical systems, always observe the following practices:

1. Never make or break any of the charging circuit connections when the engine is running, including the battery

connections.

2. Never short any of the charging components to ground.

3. Always disconnect the ground cable from the battery before arc welding on the machine or on any machine

attachment.

• Position the welder ground clamp as close to the welding area as possible.

• If you weld in close proximity to a computer module, then you should remove the module from the machine.

• Never allow welding cables to lie on, near, or across any electrical wiring or electronic component while you

weld.

4. Always disconnect the negative cable from the battery when charging the battery in the machine with a battery

charger.

NOTICE: If you must weld on the unit, you must disconnect the battery ground cable from the machine battery.

The electronic monitoring system and charging system will be damaged if this is not done.

5. Remove the battery ground cable. Reconnect the cable when you complete welding.
