    Introduction

    The 1300 Series EDi is a family of engines which have an electronic management system. The engines are

    designed for industrial and agricultural applications from Perkins Engines Limited, a world leader in the design

    and manufacture of high-performance diesel engines.

    Perkins approved assembly and quality standards, together with the latest technology, have been applied to

    the manufacture of your engine to give you reliable and economic power.

    Note: To ensure that you use the relevant information for your specific engine type, refer to "Engine

    identification" on page 6.

    Danger is indicated in the text by two methods:

    Warning! This indicates that there is a possible danger to the person.

    Caution: This indicates that there is a possible danger to the engine.

    Note: Is used where the information is important, but there is not a danger.

    Safety precautions

    These safety precautions are important.

    You must refer also to the local regulations in the country of use. Some items only apply to specific

    applications.

    z   Only use these engines in the type of application for which they have been designed.

    z   Do not change the specification of the engine.

    z   Do not smoke when you put fuel in the tank.

    z   Clean away fuel which has been spilt. Material which has been contaminated by fuel must be moved to a

    safe place.

    z   Do not put fuel in the tank while the engine runs (unless it is absolutely necessary).

    z   Do not clean, add lubricating oil, or adjust the engine while it runs (unless you have had the correct training;

    even then extreme caution must be used to prevent injury).

    z   Do not make adjustments that you do not understand.

    z   Ensure that the engine does not run in a location where it can cause a concentration of toxic emissions.

    z   Other persons must be kept at a safe distance while the engine or auxiliary equipment is in operation.

    z   Do not permit loose clothing or long hair near moving parts.

    z   Keep away from moving parts during engine operation.

    Warning! Some moving parts cannot be seen clearly while the engine runs.

    z   Do not operate the engine if a safety guard has been removed.

    z   Do not remove the filler cap or any component of the cooling system while the engine is hot and while the

    coolant is under pressure, because dangerous hot coolant can be discharged.

    z   Do not use salt water or any other coolant which can cause corrosion in the closed coolant circuit.

    z   Do not allow sparks or fire near the batteries (especially when the batteries are on charge) because the

    gases from the electrolyte are highly flammable. The battery fluid is dangerous to the skin and especially

    to the eyes.

    z   Disconnect the battery terminals before a repair is made to the electrical system.

    z   Only one person must control the engine.

    z   Ensure that the engine is operated only from the control panel or from the operator's position. Discard used

    lubricating oil in a safe place to prevent contamination.

    z   Ensure that the control lever of the transmission drive is in the "out-of-drive" position before the engine is

    started.

    z   The combustible material of some components of the engine (for example certain seals) can become

    extremely dangerous if it is burned. Never allow this burnt material to come into contact with the skin or with

    the eyes.

    z   Diesel fuel and lubricating oil (especially used lubricating oil) can damage the skin of certain persons.

    Protect your hands with gloves or a special solution to protect the skin.

    z   Do not wear clothing which is contaminated by lubricating oil. Do not put material which is contaminated

    with oil into the pockets of clothing.

    z   Discard used lubricating oil in accordance with local regulations to prevent contamination.

    z   Use extreme care if emergency repairs must be made in adverse conditions.

    z   Always use a safety cage to protect the operator when a component is to be pressure tested in a container

    of water. Fit safety wires to secure the plugs which seal the hose connections of a component which is to

    be pressure tested.

    z   Do not allow compressed air to contact your skin. If compressed air enters your skin, obtain medical help

    immediately.

    z   Turbochargers operate at high speed and at high temperatures. Keep fingers, tools and debris away from

    the inlet and outlet ports of the turbocharger and prevent contact with hot surfaces.

    z   The fuel injector units of this engine are controlled electronically by a pulse of 110 volts.

    z   The fuel injector units are actuated by high-pressure engine lubricating oil. Do not remove any component

    of the high-pressure system while the engine oil is under pressure, because dangerous oil can be

    discharged.

    z   Fit only genuine Perkins parts.

    How to care for your engine

    This handbook has been written to assist you to maintain and operate your engine correctly.

    To obtain the best performance and the longest life from your engine, you must ensure that the maintenance

    operations are done at the intervals indicated in Chapter 4, Preventive maintenance. If the engine works in a

    very dusty environment or other adverse conditions, certain maintenance intervals will have to be reduced.  

    Renew the filter canisters and lubricating oil regularly in order to ensure that the inside of your engine remains

    clean.

    Ensure that all adjustments and repairs are done by personnel who have had the correct training. Perkins

    distributors have this type of personnel available. You can also obtain parts and service from your Perkins

    distributor.

    The terms "left side" and "right side" apply when the engine is seen from the flywheel end.

    Warning! Read the "Safety precautions" on page 2 and remember them. They are given for your protection

    and must be applied at all times.

    Engine preservation

    Introduction

    The recommendations indicated below are designed to prevent damage to the engine when it is withdrawn

    from service for a prolonged period. Use these procedures after the engine is withdrawn from service.

    Procedure

    Caution: The procedure for this engine is different to the procedure for other Perkins engines, because of the

    design of the fuel injection units.

    1  Completely clean the outside of the engine.

    2  Operate the engine until it is warm. Stop the engine and drain the lubricating oil from the sump. Ensure that

    the oil gallery of the high-pressure lubrication system is drained.

    Caution: If the gallery is not drained, the engine cylinders will be filled with engine lubricating oil when the fuel

    injector units are removed.

    3  Drain the fuel supply gallery, fitted to the cylinder head.

    Caution: If the gallery is not drained, the engine cylinders will be filled with fuel when the fuel injector units are

    removed.

    4  Renew the canister of the lubricating oil filter, see "How to renew the canister of the lubricating oil filter" on

    page 26.

    5  Fill the sump to the full mark on the dipstick with new and clean lubricating oil. Use a correct preservative

    fluid instead of the lubricating oil. If a preservative fluid is used, this must be drained and the lubricating oil

    sump must be filled to the correct level with normal lubricating oil at the end of the storage period.

    6  Drain the coolant circuit, see "How to drain the cooling system" on page 19. In order to protect the cooling

    system against corrosion, fill it with an approved antifreeze mixture because this gives protection against

    corrosion.

    Caution: If protection against frost is not necessary and a corrosion inhibitor is to be used, it is recommended

    that you consult the Technical Service Department, Perkins Engines Company Limited, Peterborough.

    7  Connect the battery, eliminate air from the fuel system. Operate the engine for a short period in order to

    circulate the lubricating oil and the coolant in the engine. Then correct leakages of fuel, lubricating oil or air.

    8  Disconnect the battery. Then put the battery into safe storage in a fully charged condition. Before the battery

    is put into storage, protect its terminals against corrosion.

    9  Remove the air filter. Then, if necessary, remove the pipe(s) installed between the air filter and the

    turbocharger. Seal the air inlet to the turbocharger with waterproof tape.

    1300 Series EDi Models WK to WS

    10  Remove the exhaust pipe. Seal the manifold or the turbocharger with waterproof tape.

    11  Clean the engine breather pipe and seal the end of the pipe.

    12  When a preservative fuel is to be used, drain the fuel system and fill it with the preservative fuel. If

    preservative fuel is not used, the system can be completely filled with normal fuel but the fuel must be drained

    and discarded at the end of the storage period together with the fuel filter canister.

    13  Remove the drive belts and put them into storage.

    14  Seal the vent pipe of the fuel tank or the fuel filler cap with waterproof tape.

    Every month, the crankshaft must be rotated in order to change the spring loading on the valve train. Rotate

    the crankshaft more than 180 degrees. Visibly check for damage or corrosion to the engine.

    If the engine protection is done correctly according to the above recommendations, no corrosion damage will

    normally occur. Perkins are not responsible for damage which may occur when an engine is in storage after a

    period in service.

    Parts and service

    If problems occur with your engine or with the components fitted onto it, your Perkins distributor can make the

    necessary repairs and will ensure that only the correct parts are fitted and that the work is done correctly.

    Training

    Local training for the correct operation, service and overhaul of engines is available at certain Perkins

    distributors. If special training is necessary, your Perkins distributor can advise you how to obtain it at the

    Perkins Customer Training Department, Peterborough, or other main centres.

    Service literature

    Workshop manuals, installation drawings and other service publications are available from your Perkins

    distributor at a nominal cost.

    How to start the engine

    Temperature of 15°C (60°F) to -10°C (14°F)

    Several factors affect engine start, for example:

    z   The power of the batteries

    z   The performance of the starter motor

    z   The viscosity of the lubricating oil

    z   The installation of a cold start system.

    The engine will start without a cold starting aid at temperatures as low as -10 °C (14 °F). In conditions where

    the temperature is lower than this, a block heater or an ether start system may be necessary.

    Before the engine is started the operator should understand fully the reason for the controls and their use.

    Before the engine is started:

    z   Check that there is sufficient coolant and, if necessary, add the correct coolant, see Chapter 4, Preventive

    maintenance.

    z   Check that there is sufficient lubricating oil in the sump and, if necessary, add lubricating oil. Refer to

    Chapter 4, Preventive maintenance. Ensure that the lubricating oil is of the correct grade for the ambient

    conditions.

    z    Fill the fuel tank with fuel of the correct specification, see Chapter 5, Engine fluids.

    z    Check the air filter and its connections.

    z    Ensure that all of the electrical connections are tight.

    Notes:

    z   For the correct engine fluids, see Chapter 5, Engine fluids.

    z   The procedures to start the engine may vary according to the application. If possible, consult the User's

    Handbook for the application.

    1  Apply the hand brake, if the application is fitted with one. Ensure that the transmission is in the out-of-drive

    position. Ensure that the engine speed control is in the minimum speed position.

    2  Turn the start key to the "ON" position.

    Note: Do not operate the engine speed control during engine start, the management system controls the

    supply of fuel, and it will ignore signals from the speed control until the engine starts.

    3  Turn the start key further to engage the starter motor. If the application has a start button, press and hold

    the button.

    4  Release the start key (or the button) as soon as the engine starts. The start key will return to the "ON"

    position.

    Caution: If the engine does not start within 30 seconds, release the start key and wait two to three minutes to

    allow the starter motor to cool. If after three tries the engine does not start, turn the key to the "OFF" position.

    When the engine starts, check that the lubricating oil pressure exceeds 138 kPa (20 lbs/in ) 1,4 kgf/cm   within

    the first 10 seconds, see "Engine data" on page 8 for the correct lubricating oil pressure.

    If a gauge is not fitted, check that the warning light for low oil pressure is extinguished. If this does not occur,

    stop the engine and find and correct the fault. Allow the engine to warm at approximately 1000 rev/min for three

    to five minutes before load is applied.

    How to start an engine with an ether start system

    Ambient temperature below -20°C (-4°F)

    Caution: Ether is very flammable and is toxic. Apply the safety precautions on the container for the use and

    storage of ether and for the disposal of empty containers.

    1  Apply the hand brake. Ensure that the transmission is in the out-of-drive position. Check the ether container

    to ensure that a supply of ether is available under pressure.

    2  Ensure that the engine speed control is still in the idle position.

    Note: Do not operate the engine speed control during engine start, the management system controls fuel

    supply and it will ignore signals from the speed control until the engine starts.

    3  Turn the start key to the "ON" position.

    4  Turn the start key further to engage the starter motor. If the application has a start button, press and hold

    the button to engage the starter motor, and at the same time press the ether injection button. Allow one to two

    seconds for the ether injection system to fill then release the injection button to release a measured amount of

    ether into the engine.

    Caution: Release of ether into the cylinders before the starter motor is engaged may cause damage to the

    pistons and piston rings.

    5  Release the start key (or the start button, if one is fitted) as soon as the engine starts. The start key will return

    to the "ON" position.

    Caution: If the engine does not start within 30 seconds, release the start key and wait two to three minutes to

    allow the starter motor to cool. If after three tries the engine does not start, turn the key to the "OFF" position

    and locate and correct the problem. Always ensure that the engine and starter motor are stationary before the

    starter motor is engaged again.

    Note: In extemely cold conditions, it is permissible to inject further ether into the engine if the engine runs

    roughly after the initial start.

    Caution: Do not inject ether into a warm engine.

    6  When the engine starts check that the lubricating oil pressure exceeds 138 kPa (20 lbs/in  ) 1,4 kgf/cm2

    within the first 25 seconds, see "Engine data" on page 8 for the correct lubricating oil pressure. If a gauge is

    not fitted, check that the warning light for low oil pressure is extinguished. If this does not occur, stop the

    engine.

    2

    Find and correct the fault. Allow the engine to warm at approximately 1000 rev/min for three to five minutes

    before load is applied.

    How to stop the engine

    Turn the engine start key to the "OFF" position.

    It is recommended that the engine is operated at idle speed for three to five minutes before the engine is

    stopped. This will allow the lubricating oil and the coolant to carry the heat away from large ferrous

    components.

    Adjustment of engine speed range

    The idle or maximum speed settings cannot be changed by the engine operator.

    Engine operation at idle speed

    Do not operate the engine for long periods at idle speed as this could have an adverse affect on the engine

    performance or damage the engine.

    Running-in

    A gradual running-in of a new engine is not necessary. Prolonged operation at light loads during the early life

    of the engine is not recommended.

    Maximum load can be applied to a new engine as soon as the engine is put into service and the coolant

    temperature has reached a minimum of 76 °C (170 °F).

    z   Do not operate the engine at high speeds without a load.

    z   Do not overload the engine.

    Altitude

    The engine management system will automatically compensate for altitude.

    Preventive maintenance periods

    These preventive maintenance periods apply to average conditions of operation. Check the periods given by

    the manufacturer of the equipment in which the engine is installed. Use the periods which are shortest . When

    the operation of the engine must conform to the local regulations these periods and procedures may need to

    be adapted to ensure correct operation of the engine.

    It is good preventive maintenance to check for leakage and loose fasteners at each service.

    These maintenance periods apply only to engines that are operated with fuel and lubricating oil which conform

    to the specifications given in this handbook.

    How to renew the canister of the coolant filter / inhibitor

    Warning! Do not remove the canister while the engine is still hot and under pressure because dangerous hot

    fluid can be discharged.

    Caution: The canister contains a corrosion inhibitor which is circulated around the cooling system as the

    coolant passes through the canister. It is important that only the genuine correct Perkins canister is used.

    Note: There are two types of coolant filter head:

    Type 1

    1  When the engine has cooled, remove the radiator filler cap to release the system pressure.

    Note: When the system pressure is released, valves will close in the filter canister and in the housing for the

    canister. This will prevent the loss of coolant when the filter is removed.

    2  Thoroughly clean the outside surfaces of the coolant filter assembly.

    3  Use a strap wrench or similar tool to loosen the filter canister and remove the canister. Valves in the filter

    head will prevent the loss of coolant when the canister is removed.

    4  Ensure that the threaded adaptor (A2) is secure in the filter head and that the inside of the head is clean.

    5  Lubricate lightly the seal (A1) on top of the new canister with clean engine coolant. Fit the new canister to

    How to eliminate air from the fuel system

    If air enters the fuel system, it must be eliminated before the engine can be started.

    Air can enter the system if:

    z   The fuel tank is drained during normal operation.

    z   The low-pressure fuel pipes are disconnected.

    z   A part of the low-pressure fuel system leaks during engine operation.

    In order to eliminate air from the fuel system, proceed as follows:

    1  Loosen the vent plug (A1) on the top of the fuel filter head.

    2  Operate the plunger of the fuel priming pump (A2) until fuel, free from air, comes from the filter vent point.

    Tighten the vent plug.

    3  Turn the start key to the "ON" position.

    4  Operate the starter motor for intervals of 15 seconds until the engine starts. If the engine runs correctly for

    a short time and then stops or runs roughly, check for air in the fuel system. If there is air in the fuel system,

    there is probably a leakage in the low pressure system. Turn the start key to the "OFF" position to stop the

    engine. Rectify the leakage and repeat the procedure.

    Fuel specification

    To get the correct power and performance from your engine, use good quality fuel. The recommended fuel

    specification for Perkins engines is indicated below:

    Cetane number

    Viscosity

    50 minimum

    2.0/4.5 centistokes at 40 °C

    0,835/0,855 kg/litre

    0.2% of mass, maximum

    85% at 350 °C

    Density

    Sulphur

    Distillation

    Cetane number indicates ignition performance. A fuel with a low cetane number can cause cold start problems

    and affect combustion.

    Viscosity is the resistance to flow and engine performance can be affected if it is outside the limits.

    Density: A lower density reduces engine power, a higher density increases engine power and exhaust smoke.

    Sulphur: A high sulphur content (not normally found in Europe, North America or Australasia) can cause

    engine wear. Where only high sulphur fuels are available, it is necessary to use a highly alkaline lubricating oil

    in the engine or to renew the lubricating oil more frequently, see "How to renew the lubricating oil" on page 25.

    Distillation: This is an indication of the mixture of different hydrocarbons in the fuel. A high ratio of light-weight

    hydrocarbons can affect the combustion characteristics.

    Low temperature fuels

    Special winter fuels may be available for engine operation at temperatures below 0 °C. These fuels have a

    lower viscosity and also limit the wax formation in the fuel at low temperatures. If wax formation occurs, this

    could stop the fuel flow through the filter.

    If you need advice on adjustments to an engine setting or to the lubricating oil change periods which may be

    necessary because of the standard of the available fuel, consult the Technical Service Department of Perkins

    International Limited at Peterborough or your nearest Perkins Distributor.

    Aviation kerosene fuels

    Caution: Do not use aviation kerosene fuel JP4.

    JP5 and JP8 can be used, but they can affect engine performance and wear in the fuel injector units could

    increase. It is recommended that you consult the Technical Service Department of Perkins International

    Limited at Peterborough if aviation kerosene fuel is to be used.

    Aviation kerosene fuels are more flammable than diesel fuel and need careful storage and careful

    management.

    Lubricating oil specification

    The specification of lubricating oil that is recommended for these engines are API CI-4 or DHD-1.

    This specification of lubricating oil will provide the necessary protection for your engine. A higher specification

    of lubricating oil is acceptable.

    Caution: The type of lubricating oil to be used may be affected by the quality of the fuel which is available. For

    further details see "Fuel specification" on page 29.

    Always ensure that the correct viscosity grade of lubricating oil is used for the ambient temperature range in

    which the engine will run as shown in the chart (A).

    Note: The shaded areas in the chart (A) indicate the preferred viscosity grade of oil for the temperature range.

    Increase in oil consumption may be expected when SAE 0W-30, 5W-30 and 10W-30 oils are used.

    Check oil levels more frequently.

    Coolant specification

    The quality of the coolant which is used can have a great effect on the efficiency and life of the cooling system.

    The recommendations indicated below can help to maintain a good cooling system and to protect it against

    frost and/or corrosion.

    If the correct procedures are not used, Perkins cannot be held responsible for frost or corrosion damage.

    1  If it is possible, use clean soft water in the coolant.

    2  If an antifreeze mixture is used to prevent frost damage, it must have an ethanediol base (ethylene glycol)

    with a corrosion inhibitor. It is recommended that the corrosion inhibitor is of the sodium nitrite/sodium

    molybdate type. The antifreeze mixture must be an efficient coolant at all ambient temperatures and it must

    provide protection against corrosion. It must also have a specification at least as good as the requirements of

    either BS6580 or MOD AL39.

    The quality of the antifreeze coolant must be checked at least once a year, for example, at the beginning of

    the cold period. The coolant must be renewed every two years.

    The antifreeze mixture must consist of equal quantities of antifreeze and water. Concentrations of more than

    50% of antifreeze must not be used because these can affect adversely the performance of the coolant.

    3  When frost protection is not necessary, it is still an advantage to use an approved antifreeze mixture

    because this gives a protection against corrosion and also raises the boiling point of the coolant. If an approved

    antifreeze mixture is not available, add a correct mixture of corrosion inhibitor to the water.

    All 1300 Series EDi engines are supplied with a coolant filter / conditioner canister. Renew the coolant and the

    filter / conditioner canister in accordance with the maintenance "Schedules" on page 18. Test the level of

    coolant conditioner, and adjust if necessary in accordance with the maintenance "Schedules" on page 18.
