Foreword

Foreword

Recommended service should be performed at the

appropriate intervals as indicated in the Maintenance

Interval Schedule. The actual operating environment

of the engine also governs the Maintenance Interval

Schedule. Therefore, under extremely  severe,

dusty, wet or freezing cold  operating conditions,

more frequent lubrication and maintenance than is

specified in the Maintenance Interval Schedule may

be necessary.

Literature Information

This manual contains safety, operation instructions,

lubrication and maintenance information.  This

manual should be stored in or near the engine area

in a literature holder or literature storage area. Read,

study and keep it with  the literature and engine

information.

The maintenance schedule items are organized for

a preventive maintenance management program. If

the preventive maintenance program is followed, a

periodic tune-up is not required. The implementation

of a preventive maintenance management program

should minimize operating  costs through cost

avoidances resulting from reductions in unscheduled

downtime and failures.

English is the primary  language for all Perkins

publications. The English used facilitates translation

and consistency.

Some photographs or illustrations in this  manual

show details or attachments that may be different

from your engine. Guards and  covers may have

been removed for illustrative purposes. Continuing

improvement and advancement of product design

may have caused changes to your engine which are

not included in this manual. Whenever a question

arises regarding your engine, or this manual, please

consult with your Perkins dealer  or your Perkins

distributor for the latest available information.

Maintenance Intervals

Perform maintenance on items  at multiples of

the original requirement. We recommend that the

maintenance schedules be reproduced and displayed

near the engine as a convenient reminder. We also

recommend that a maintenance record be maintained

as part of the engine's permanent record.

Safety

Your authorized Perkins dealer  or your Perkins

distributor can assist  you in adjusting  your

maintenance schedule to meet the needs of  your

operating environment.

This safety section lists basic safety  precautions.

Safety Section

General Hazard Information

Perkins replacement parts that are shipped  from

Perkins are asbestos free. Perkins recommends

the use of only genuine Perkins replacement parts.

Use the following guidelines when you handle any

replacement parts that contain asbestos or when you

handle asbestos debris.

Use caution. Avoid inhaling  dust that might be

generated when you handle components that contain

asbestos fibers. Inhaling this dust can be hazardous

to your health. The components that may contain

asbestos fibers are brake pads, brake bands, lining

material, clutch plates, and  some gaskets. The

asbestos that is used in these components is usually

bound in a resin or  sealed in some way. Normal

handling is not hazardous unless airborne dust that

contains asbestos is generated.

g00687600

Illustration 8

Always use a board or cardboard when you check

for a leak. Leaking fluid that is under pressure can

penetrate body tissue. Fluid penetration can cause

serious injury and possible death. A pin hole leak can

cause severe injury. If fluid is injected into your skin,

you must get treatment immediately. Seek treatment

from a doctor that is familiar with this type of injury.

If dust that may contain asbestos is present, there

are several guidelines that should be followed:

•  Never use compressed air for cleaning.

•  Avoid brushing materials that contain asbestos.

•  Avoid grinding materials that contain asbestos.

Containing Fluid Spillage

•  Use a wet method in order to clean up asbestos

materials.

NOTICE

Care must be taken to ensure that fluids are contained

during performance of inspection, maintenance, test-

ing, adjusting and repair of the product. Be prepared to

collect the fluid with suitable containers before  open-

ing any  compartment or  disassembling any  compo-

nent containing fluids.

•  A vacuum cleaner that is equipped  with a high

efficiency particulate air filter (HEPA) can also be

used.

•  Use exhaust ventilation on permanent machining

jobs.

Dispose of all fluids according to local regulations and

mandates.

•  Wear an approved respirator if there is no other

way to control the dust.

Asbestos Information

•  Comply with applicable rules and  regulations

for the work place.  In the United States, use

Occupational Safety and Health Administration

(OSHA) requirements. These OSHA requirements

can be found in “29 CFR 1910.1001”.

Burn Prevention

Dispose of Waste Properly

Allow the pressure to be purged in the air system, in

the hydraulic system, in the lubrication system, or

in the cooling system before any lines,  fittings, or

related items are disconnected.

Induction System

Sulfuric Acid Burn Hazard may cause serious per-

sonal injury or death.

The  exhaust  gas   cooler  may  contain  a  small

amount of sulfuric acid.  The use of fuel with sul-

fur levels  greater than 15  ppm may increase  the

amount of sulfuric acid formed. The  sulfuric acid

may  spill from  the cooler  during  service of  the

engine. The sulfuric acid  will burn the eyes, skin

and clothing on  contact. Always wear the appro-

priate personal  protective  equipment (PPE)  that

is noted  on a material  safety data  sheet (MSDS)

for sulfuric acid. Always follow  the directions for

first aid  that are noted  on a material  safety data

sheet (MSDS) for sulfuric acid.

g00706404

Illustration 10

Improperly disposing of waste  can threaten the

environment. Potentially harmful fluids should be

disposed of according to local regulations.

Always use leakproof containers when you  drain

fluids. Do not pour waste onto the ground, down a

drain, or into any source of water.

i04224009

Coolant

Burn Prevention

When the engine is at operating temperature, the

engine coolant is hot. The  coolant is also under

pressure. The radiator and all lines to the heaters or

to the engine contain hot coolant.

Do not touch any  part of an operating  engine

system. The engine, the exhaust, and the  engine

aftertreatment system surface temperatures can

reach temperatures of  approximately 600° C

(1112 ° F) under normal operating conditions.

Any contact with hot coolant or with steam can cause

severe burns. Allow cooling system components to

cool before the cooling system is drained.

Check that the coolant level after  the engine has

stopped and the engine has been allowed to cool.

Allow the engine  system to cool  before any

maintenance is performed.

Ensure that the filler cap is cool before removing the

filler cap. The filler cap must be cool enough to touch

with a bare hand. Remove the filler  cap slowly in

order to relieve pressure.

Relieve all pressure  in the following systems,

hydraulic system, lubrication system, fuel system,

and the coolant system before the related items are

disconnected.

Cooling system conditioner contains alkali. Alkali can

cause personal injury. Do not allow alkali to contact

the skin, the eyes, or the mouth.

Contact with  high pressure fuel  may cause fluid

penetration and  burn hazards. High pressure  fu-

el spray  may cause  a fire  hazard. Failure to  fol-

low these inspection, maintenance and service in-

structions may cause personal injury or death.

Oils

Hot oil and hot lubricating components can cause

personal injury. Do not allow hot oil to contact  the

skin. Also, do not allow hot components to contact

the skin.

After the engine has stopped, you must wait for 10

minutes in order to allow the  fuel pressure to be

purged from the high-pressure fuel lines before any

service or repair is performed on the engine fuel lines.

All fuels, most lubricants, and some coolant mixtures

are flammable.

Flammable fluids that are leaking or spilled onto hot

surfaces or onto electrical components can cause

a fire. Fire may cause personal injury and property

damage.

Contact with  high pressure fuel  may cause fluid

penetration and  burn hazards. High pressure  fu-

el spray  may cause  a fire  hazard. Failure to  fol-

low these inspection, maintenance and service in-

structions may cause personal injury or death.

After the emergency stop button is operated ensure

that you allow 15 minutes, before the engine covers

are removed.

Determine whether the engine will be operated in an

environment that allows combustible gases to be

drawn into the air inlet system. These gases could

cause the engine to overspeed.  Personal injury,

property damage, or engine damage could result.

After the engine has stopped, you must wait for 10

minutes in order to allow  the fuel pressure to be

purged from the high pressure fuel lines before any

service or repair is performed on the engine fuel lines.

If the application involves the presence of combustible

gases, consult your Perkins  dealer and/or your

Perkins distributor for additional information about

suitable protection devices.

Ensure that the engine is stopped. Inspect all lines

and hoses for wear or for deterioration. The hoses

must be correctly routed. The lines and hoses must

have adequate support and secure clamps.

(9) Fuel transfer line that is high pressure

The high pressure fuel lines are the fuel lines  that

are between the high pressure fuel pump and  the

high pressure fuel manifold and the fuel lines that are

between the fuel manifold and cylinder head. These

fuel lines are different from fuel lines on other  fuel

systems.

Visually inspect the high pressure fuel lines before

the engine is started. This inspection should be each

day.

If you inspect the engine in operation, always use

the proper inspection procedure in order to  avoid

a fluid penetration hazard. Refer to Operation and

Maintenance Manual, “General hazard Information”.

This is because of the following items:

•  The high pressure fuel lines are constantly charged

with high pressure.

•  Inspect the high pressure fuel lines for damage,

deformation, a nick, a cut, a crease, or a dent.

•  The internal pressures of the high pressure fuel

lines are higher than other types of fuel system.

•  Do not operate the engine with a fuel leak. If there

is a leak do not tighten the  connection in order

to stop the leak. The  connection must only be

tightened to the recommended torque. Refer to

Disassembly and Assembly, “Fuel injection lines -

Remove and Fuel injection lines - Install”.

•  The high pressure fuel lines are formed to shape

and then strengthened by a special process.

Do not step on the high pressure fuel lines. Do not

deflect the high pressure fuel lines. Do not bend or

strike the high pressure fuel lines. Deformation or

damage of the high pressure fuel lines may cause a

point of weakness and potential failure.

•  If the high pressure fuel lines are torqued correctly

and the high pressure fuel lines are leaking the

high pressure fuel lines must be replaced.

•  Ensure that all clips on the high pressure fuel lines

are in place. Do not operate the engine with clips

that are damaged, missing or loose.

Do not check the high pressure fuel lines with  the

engine or the starting motor in operation. After the

engine has stopped, you must wait for 10 minutes in

order to allow the fuel pressure to be purged from the

high pressure fuel lines before any service or repair

is performed on the engine fuel lines.

•  Do not attach any other item to the high pressure

fuel lines.

•  Loosened high pressure  fuel lines must be

replaced. Also removed high pressure fuel lines

must be replaced. Refer  to Disassembly and

assembly manual, “ Fuel Injection Lines - Install”.

Do not loosen the high pressure fuel lines in order

to remove air from the fuel system. This procedure

is not required.

Before Starting Engine

i02813489

All protective guards and all protective covers must

be installed if the engine must be started  in order

to perform service procedures. To help prevent an

accident that is caused by parts  in rotation, work

around the parts carefully.

Before Starting Engine

Before the initial start-up of an engine that is new,

serviced or repaired, make provision  to shut the

engine off, in order to stop an overspeed. This may

be accomplished by shutting off the air and/or fuel

supply to the engine.

Start the engine from the operators compartment or

from the engine start switch.

Always start the engine according to the procedure

that is described in the Operation and Maintenance

Manual, “Engine Starting” topic in  the Operation

Section. Knowing that the correct procedure will help

to prevent major damage to the engine components.

Knowing that the procedure will also help to prevent

personal injury.

Overspeed shutdown should occur automatically for

engines that are controlled electronically. If automatic

shutdown does not occur, press the emerg, ency stop

button in order to cut the fuel and/or air to the engine.

Inspect the engine for potential hazards.

To ensure that the jacket water heater (if equipped)

and/or the lube oil heater (if equipped) is  working

correctly, check the water temperature gauge. Also,

check the oil temperature gauge during the heater

operation.

Before starting the engine, ensure that no one is on,

underneath, or close to the engine. Ensure that the

area is free of personnel.

If equipped, ensure that the lighting system for the

engine is suitable for the conditions. Ensure that all

lights work correctly, if equipped.

Engine exhaust contains products of combustion

which can be harmful to your health. Always start the

engine and operate the engine in a well ventilated

area. If the engine is started in an  enclosed area,

vent the engine exhaust to the outside.

All protective guards and all protective covers must

be installed if the engine must be started  in order

to perform service procedures. To help prevent an

accident that is caused by parts in  rotation, work

around the parts carefully.

Note: The engine is equipped with a device for cold

starting. If the engine will be operated in very cold

conditions, then an extra cold starting aid may be

required. Normally, the engine will be equipped with

the correct type of starting  aid for your region of

operation.

Do not bypass the automatic shutoff circuits. Do not

disable the automatic shutoff circuits. The circuits are

provided in order to help prevent personal injury. The

circuits are also provided in order to  help prevent

engine damage.

These engines are equipped with a glow plug starting

aid in each individual cylinder that heats the intake air

in order to improve starting. Some Perkins engines

may have a cold starting system that is controlled by

the ECM that allows a controlled flow of ether into

the engine. The ECM will disconnect the glow plugs

before the ether is introduced. This system would

be installed at the factory.

See the  Service Manual for repairs  and for

adjustments.

Grounding Practices

Use the Emergency Stop Button (if equipped) ONLY

in an emergency situation. Do not use the Emergency

Stop Button for normal engine stopping.  After an

emergency stop, DO NOT start the engine until the

problem that caused the emergency stop has been

corrected.

Stop the engine if an overspeed condition  occurs

during the initial start-up of a new engine or an engine

that has been overhauled.

To stop an electronically controlled engine, cut the

power to the engine and/or shutting off the air supply

to the engine.

i04193189

Electrical System

Never disconnect any charging unit circuit or battery

circuit cable from the battery when the charging unit

is operating. A spark can cause  the combustible

gases that are produced by some batteries to ignite.

To help prevent sparks from igniting  combustible

gases that are produced by  some batteries, the

negative “−” cable should be connected last  from

the external power source to the primary position for

grounding.

Correct grounding for the engine electrical system

is necessary for optimum  engine performance

and reliability. Incorrect grounding  will result in

uncontrolled electrical circuit paths and in unreliable

electrical circuit paths.

The following actions  are available for engine

monitoring control:

Uncontrolled electrical circuit paths can  result in

damage to the crankshaft bearing journal surfaces

and to aluminum components.

•  Warning

•  Derate

Engines that are installed without engine-to-frame

ground straps can  be damaged by electrical

discharge.

•  Shutdown

The following monitored engine operating conditions

have the ability to limit  engine speed and/or the

engine power:

To ensure that the engine and the engine electrical

systems function correctly, an  engine-to-frame

ground strap with a direct path to the battery must be

used. This path may be provided by way of a direct

engine ground to the frame.

•  Engine Coolant Temperature

•  Engine Oil Pressure

The connections for the grounds should be tight and

free of corrosion. The engine  alternator must be

grounded to the negative “-” battery terminal. The

The cooling system and lubrication system consists

of the following components:

•  Gear-driven centrifugal water pump

•  Water temperature regulator which regulates the

engine coolant temperature

•  Engine monitoring

•  Gear-driven rotor type oil pump

•  Oil cooler

•  Engine speed governing

•  Control of the injection pressure

•  Cold start strategy

The engine lubricating oil is supplied by a rotor type

oil pump. The engine lubricating oil is cooled and the

engine lubricating oil is filtered. The bypass valve

can provide unrestricted flow of  lubrication oil to

the engine if the oil filter element  should become

plugged.

•  Automatic air/fuel ratio control

•  Torque rise shaping

Engine efficiency, efficiency of emission controls, and

engine performance depend on adherence to proper

operation and maintenance recommendations.

Engine performance and efficiency also depend on

the use of recommended fuels, lubrication oils, and

coolants. Refer to this Operation and Maintenance

Manual, “Maintenance Interval Schedule” for more

information on maintenance items.

•  Injection timing control

•  System diagnostics

•  Low temperature regeneration

For more information on electronic engine features,

refer to the Operation and Maintenance  Manual,

Clean Emission Module (CEM)

The CEM comprises of two main components in a

single unit, the Diesel Oxidation Catalyst DOC and

the Diesel Particulate Filter DPF. The function of the

CEM is to ensure that the  engine exhaust meets

the required emissions regulation for the country of

operation.

The engine exhaust is connected by a flexible pipe to

the CEM. The exhaust gases pass through the DOC

in order to remove contaminants, carbon monoxide,

and hydrocarbons. The exhaust gases then enter the

DPF where any particulate matter soot and ash will

be trapped.

The CEM uses a passive regeneration process to

ensure that normal operation of the engine removes

the soot. The soot is removed at  an equal rate of

which the soot is captured. The ash remains in the

DPF and must be removed at an engine overhaul.

Engine Service Life

Engine efficiency and maximum utilization of engine

performance depend on the adherence to  proper

operation and maintenance recommendations. In

addition, use recommended fuels, coolants,  and

lubricants. Use the Operation and  Maintenance

Manual as a guide for required engine maintenance.

Expected engine life is generally predicted by the

average power that is demanded. The average power

that is demanded is based on fuel consumption of

the engine over a period of time. Reduced hours of

operation at full throttle and/or operating at reduced

throttle settings result in a  lower average power

demand. Reduced hours of operation will increase

the length of  operating time before an engine

overhaul is required. For more information, refer to

the Operation and Maintenance Manual, “Overhaul

Considerations” topic (Maintenance Section).

Aftermarket Products and Perkins

Engines

Perkins does not warrant the quality or performance

of non-Perkins fluids and filters.

When auxiliary devices, accessories, or consumables

(filters, additives, catalysts,) which are made by other

manufacturers are used on Perkins products, the

Perkins warranty is not affected simply because of

such use.

However, failures that result from the installation

or use  of other manufacturers  devices,

accessories, or consumables are NOT Perkins

defects. Therefore, the defects are NOT covered

under the Perkins warranty.
