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 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.

z   If your skin comes into contact with high-pressure fuel, obtain medical assistance immediately.

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

started.

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

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   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 other objects away

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

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. The

instructions for the use of POWERPART products are given on the outside of each container.

Procedure

1  Completely clean the outside of the engine.

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

POWERPART Lay-Up 1 can be added to the normal fuel to change it to a 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.

3  Operate the engine until it is warm. Then correct leakages of fuel, lubricating oil or air. Stop the engine and

drain the lubricating oil from the sump.

4  Renew the canister of the lubricating oil filter.

5  Fill the sump to the full mark with new and clean lubricating oil and add POWERPART Lay-up 2 to the oil to

protect the engine against corrosion. If POWERPART Lay-Up 2 is not available, 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 21. In order to protect the cooling

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

corrosion, see "Coolant specification" on page 35.

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 Sales and Service Limited, Peterborough.

7  Operate the engine for a short period in order to circulate the lubricating oil and the coolant in the engine.

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. POWERPART Lay-Up 3 can be used on the

terminals.

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

10  Remove the atomisers and spray POWERPART Lay-Up 2 for one to two seconds into each cylinder bore

with the piston at bottom dead centre.

Slowly turn the crankshaft one revolution and then fit the atomisers, complete with new seat washers.

11  Disconnect the air inlet pipe at the rocker cover. Release the cap screws and remove the rocker cover.

Spray POWERPART Lay-Up 2 around the rocker shaft assembly and into the induction ports in the cylinder

head, as indicated on the container label. Fit the rocker cover and connect the air inlet pipe.

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.

12  Remove the exhaust pipe. Spray POWERPART

Lay-Up 2 into the exhaust manifold or the turbocharger. It is recommended that the spray time for the

turbocharger is 50% longer than the spray time for the manifold, which is indicated on the container label. Seal

the manifold or the turbocharger with waterproof tape.

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

14  Remove the drive belts and put them into storage.

1300 Series Models WF to WJ

15  In order to prevent corrosion, spray the engine with POWERPART Lay-Up 3. Do not spray the area inside

the alternator cooling fan.

Caution: After a period in storage, but before the engine is started, operate the starter motor with the engine

stop control in the "stop" position until oil pressure is indicated. Oil pressure can be indicated either by a gauge

or when a low pressure warning light is extinguished. If a solenoid stop control is used on the fuel injection

pump, it must be disconnected for this operation.

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.

How to start the engine

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 with the fuel injection pump in excess fuel at temperatures as low as -20 °C (-4 °F). In

conditions where the temperature is lower than this, 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. Refer to 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.

z   Check the air filter and its connections.

z   Ensure that all of the electrical connections are tight.

Notes:

z   Refer to Chapter 5, Engine fluids for the correct 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.

Caution: If the engine has not run for several weeks, see Caution on page 5.

How to start a warm engine

Ambient temperature more than 15 °C (60 °F)

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

speed control is in the minimum speed position.

2  If the engine is equipped with a manual stop control, ensure that it is in the "run" position.

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

4  Continue to turn the start key to engage the starter motor. If the application has a start button, press and

hold the button.

5  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

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

starter motor is engaged again.

How to stop the engine

According to the equipment fitted, either turn the engine start key to the "OFF" position or operate the manual

stop control. If a manual stop control is used, ensure that the control returns to the "run" position after the

engine has stopped. Also ensure that the engine start key is turned 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.

Caution: It is recommended that a turbocharged engine is run at approximately 1000 rev/min at a reduced

load for 2-3 minutes before it is shut down. This will allow the turbocharger to cool.

Adjustment of engine speed range

The idle or maximum speed settings must not be changed by the engine operator because this can damage

the engine or the transmission. The warranty of the engine can be affected if the seals on the fuel injection

pump are broken during the warranty period by a person who is not approved by Perkins.

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. Maximum load can be applied to a new engine as soon

as the engine is put into service.

z   The engine will benefit if the load is applied as soon as possible after the engine is put into service.

z   Before maximum load is applied to the engine, ensure that the coolant is at normal working temperature.

z   Prolonged operation at light loads during the early life of the engine can cause lubricating oil to enter the

exhaust system.

Cautions:

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

z   Do not overload the engine.

Altitude

The engine will run correctly up to an altitude of 3000 m (10,000 ft). If the engine is to run at an altitude above

3000 m (10,000 ft), changes must be made to the settings of the fuel injection pump. These changes must be

made by a Perkins distributor or by an approved distributor for the fuel injection pump.

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.

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 (A). 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

the filter head and tighten, by hand only. Do not overtighten the canister.

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

Density

Sulphur

Distillation

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

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, refer to the maintenance "Schedules" on page 20.

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 injection pump 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.

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

management.

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, other than Perkins POWERPART, 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 benzoate 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. Perkins POWERPART antifreeze exceeds the

requirements of the above standard.

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.

Caution: Certain corrosion inhibitor mixtures could cause damage to some engine components. It is

recommended that the corrosion inhibitor available from Perkins distributors is used. The part numbers for this

corrosion inhibitor are: 1 815 586 C1 (0,6 litre); 1 815 587 C1 (1,0 litre); 1 815 583 C1 (208 litre). If there is

doubt about the corrosion inhibitor to be used, contact the Service Department, Perkins International Limited,

Peterborough.

Renew the coolant and coolant filter in accordance with the maintenance "Schedules" on page 20.
