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.

General Hazard Information

Containing Fluid Spillage

When pressurized air and/or pressurized water is

used for cleaning, wear protective clothing, protective

shoes, and eye protection. Eye protection includes

goggles or a protective face shield.

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.

The maximum air pressure for cleaning purposes

must be below 205 kPa  (30 psi). The maximum

water pressure for cleaning purposes must be below

275 kPa (40 psi).

Fluid Penetration

Dispose of all fluids according to local regulations and

mandates.

Pressure can be trapped in the hydraulic circuit long

after the engine has been stopped. The pressure can

cause hydraulic fluid or items such as pipe plugs to

escape rapidly if the pressure is not relieved correctly.

Asbestos Information

Do not remove any hydraulic components or parts

until pressure has been relieved or personal injury

may occur. Do  not disassemble any hydraulic

components or parts until pressure has been relieved

or personal injury may occur.  Refer to the OEM

information for any procedures that are required to

relieve the hydraulic pressure.

g00702022

Illustration 7

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 6

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.

•  Use a wet method in order to clean up asbestos

materials.

Burn Prevention

•  A vacuum cleaner that is equipped  with a high

efficiency particulate air filter (HEPA) can also be

used.

Relieve all pressure  in the following systems,

hydraulic system, lubrication system, fuel system,

and the coolant system before the related items are

disconnected.

•  Use exhaust ventilation on permanent machining

jobs.

After the engine has stopped, you must wait for 10

minutes in order to allow the pressure to be purged

from the high-pressure lines before any service or

repair is performed on the engine lines.

•  Wear an approved respirator if there is no other

way to control the dust.

•  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”.

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

•  Obey environmental regulations for the disposal

of asbestos.

•  Stay away from areas that might have asbestos

particles in the air.

Sulfuric Acid Burn Hazard may cause serious per-

sonal injury or death.

Dispose of Waste Properly

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.

Coolant

g00706404

Illustration 8

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.

Improperly disposing of waste  can threaten the

environment. Potentially harmful fluids should be

disposed of according to local regulations.

Any contact with hot coolant or with steam can cause

severe burns. Allow cooling system components to

cool before the cooling system is drained.

Always use leakproof containers when you  drain

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

drain, or into any source of water.

Check that the coolant level after  the engine has

stopped and the engine has been allowed to cool.

i04259330

Burn Prevention

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.

Do not touch any  part of an operating  engine

system. Allow the engine system to cool before any

maintenance is performed.

Cooling system conditioner contains alkali. Alkali can

(1) High-pressure oil line

(2) High-pressure oil pump

The high-pressure oil line is the line that is between

the high-pressure oil pump and the high-pressure oil

manifold within the cylinder head. This high-pressure

line is different from fuel lines on other fuel systems.

•  Do not operate the engine with a leak.  Refer to

Disassembly and Assembly, “High-Pressure Oil

Line- Remove and Install”.

•  If the high-pressure oil line is torqued  correctly,

and the high-pressure  oil line is leaking the

high-pressure oil line must be replaced.

These differences are because of the following items:

•  The high-pressure oil line is constantly charged

with high pressure.

•  Do not attach any other item to the high-pressure

oil line.

•  The internal pressure of the high-pressure oil line

is higher than other types of fuel systems.

i02813489

Do not step on the high-pressure  oil line. Do not

deflect the high-pressure oil line.  Do not bend or

strike the high-pressure oil  line. Deformation or

damage of the high-pressure oil line may cause a

point of weakness and potential failure.

Before Starting Engine

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.

Do not check the  high-pressure oil line with the

engine or the starting motor in operation. After the

engine has stopped, wait 10 minutes in order to allow

the pressure to be purged from the high-pressure oil

line, before any service or repair is performed.

Overspeed shutdown should occur automatically for

engines that are controlled electronically. If automatic

shutdown does not occur, press the emergency stop

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

Visually inspect the high-pressure oil line 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”.

Inspect the engine for potential hazards.

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

underneath, or close to the engine. Ensure that the

area is free of personnel.

•  Inspect the high-pressure oil line  for damage,

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

If equipped, ensure that the lighting system for the

engine is suitable for the conditions. Ensure that all

lights work correctly, if equipped.

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.

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.

Note: The engine may be 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.

See the  Service Manual for repairs  and for

adjustments.

Engine Stopping

Stop the engine according  to the procedure in

the Operation and Maintenance Manual, “Engine

Stopping (Operation Section)” in  order to avoid

overheating of the engine and accelerated wear of

the engine components.

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.

Do not use aerosol types of starting aids such as

ether. Such use could  result in an explosion and

personal injury.

If a warning tag is attached to the engine start switch

or to the controls DO NOT start the engine or move

the controls. Consult with the person that attached

the warning tag before the engine is started.

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.

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

i04259711

Electrical System

Start the engine from the operator's 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 the correct procedure will help to

prevent major damage to the engine components.

Knowing the procedure will also  help to prevent

personal injury.

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.

Grounding Practices

Tampering with the electronic system installation

or the OEM  wiring installation can be dangerous

and could result in personal injury or death and/or

engine damage.

This engine has a comprehensive, programmable

Engine Monitoring System. The Engine  Control

Module (ECM) has the ability to monitor the engine

operating conditions. If any of the engine parameters

extend outside an allowable range, the  ECM will

initiate an immediate action.

The following actions  are available for engine

monitoring control: WARNING, ACTION ALERT, and

SHUTDOWN.

Many of the parameters that are monitored by the

ECM can be programmed for the engine monitoring

functions. The following parameters can be monitored

as a part of the Engine Monitoring System:

g02430157

(4) Ground to stating motor

•  Intake Manifold Air Pressure

•  Intake Manifold Temperature

•  Coolant Temperature

•  Engine Oil Pressure

•  Engine Oil Temperature

•  Crankshaft Position

•  Camshaft Position

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.

Uncontrolled electrical circuit paths can  result in

damage to the crankshaft bearing journal surfaces

and to aluminum components.

Engines that are installed without engine-to-frame

ground straps can  be damaged by electrical

discharge.

•  Fuel Pressure

•  System Voltage

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.

The Engine Monitoring package can vary for different

engine models and different engine applications.

However, the monitoring system and  the engine

monitoring control will be similar for all engines.

The connections for the grounds should be tight and

free of corrosion. The engine  alternator must be

grounded to the negative “-” battery terminal  with

a wire that is adequate to handle the full  charging

current of the alternator.

General Information

The diesel fuel is drawn from  the fuel tank into a

strainer and into a fuel pump. The fuel pump sends

the fuel into the main fuel filter. From the main fuel

filter the fuel is sent internally to the fuel injectors by

means of an internal fuel manifold. The fuel injectors

use engine lubricating oil  from a high-pressure

pump in order to increase the  injection pressure.

The injectors are controlled by the engine electronic

control module (ECM).

NOTICE

Never bend the eyebolts and the brackets. Only load

the eyebolts and the brackets under tension. Remem-

ber that the capacity of an eyebolt is less as the angle

between the supporting members and  the object be-

comes less than 90 degrees.

Level “C ”

In order to protect the product to Level “C”, contact

Perkins Engines Company Limited Stafford.

When it  is necessary to  remove a component at  an

angle, only use a link bracket that is properly rated for

the weight.

Use a hoist to  remove heavy components. Use

an adjustable lifting beam  to lift the engine. All

supporting members (chains and cables) should be

parallel to each other. The chains and cables should

be perpendicular to the top of the object that is being

lifted.

Some removals require lifting the fixtures in order to

obtain proper balance and safety.

To remove the engine ONLY, use the lifting eyes that

are on the engine.

Lifting eyes are designed and installed for specific

engine arrangements. Alterations to the lifting eyes

and/or the engine make the lifting eyes and the lifting

fixtures obsolete. If alterations are made,  ensure

that proper lifting devices are provided. Consult your

the gauges that are described. For more information

about the gauge package, see the OEM information.

Gauges provide indications of engine performance.

Ensure that the gauges are in good working order.

Determine the normal operating range by observing

the gauges over a period of time.

The shutoffs are electrically operated or mechanically

operated. The electrically operated shutoffs  are

controlled by the ECM.

Noticeable changes in gauge  readings indicate

potential gauge or engine problems. Problems may

also be indicated by gauge readings that  change

even if the  readings are within specifications.

Determine and correct the cause of any significant

change in the  readings. Consult your Perkins

distributor for assistance.

Shutoffs are set at critical levels  for the following

items:

•  Operating temperature

•  Operating pressure

•  Operating level

NOTICE

If no  oil pressure  is  indicated, STOP  the engine.  If

maximum  coolant temperature  is  exceeded,  STOP

the engine. Engine damage can result.

The particular shutoff may need to be reset before

the engine will start.

NOTICE

Always determine the cause of the engine shutdown.

Make necessary  repairs before attempting to  restart

the engine.

Engine Oil Pressure  – The engine oil

pressure at idle is 103 kPa (15 psi).

•  The 1600A oil pressure at  full load can range

between 340 to 360 kPa (49 to 52 psi)

Be familiar with the following items:

•  Types and locations of the shutoff

•  The 1600D oil pressure at full load  operates at

370 kPa (53 psi)

•  Conditions which cause each shutoff to function

Jacket Water Coolant Temperature  –

Typical water temperature into the engine

is 88° to 109°C (190° to 228°F).  Higher

following shutdown for emergency maneuvers, if

necessary.

“Warning”

The orange “Warning” lamp will turn “ON” and the

warning signal is activated continuously in order to

alert the operator that one or  more of the engine

parameters is not within normal operating range.

“Derate”

NOTICE

The  Engine Monitoring  System  is not  a  guarantee

against  catastrophic   failures.  Programmed  delays

and derate schedules are designed to minimize false

alarms and provide  time for the operator  to stop the

engine.

The engine will be derated if the  engine exceeds

preset operational limits. The  engine derate is

achieved by restricting the amount of  fuel that is

available for each injection.  The amount of this

reduction of fuel is dependent on the severity of the

fault that has caused the engine derate, typically up

to a limit of 50%. This reduction in fuel results in a

predetermined reduction in engine power.

The following parameters are monitored:

•  Coolant temperature

“Shutdown”

•  Intake manifold air temperature

•  Intake manifold air pressure

•  Oil pressure

The orange warning will  turn “ON” and the red

shutdown lamp will also turn “ON”.

Engine Operation with Active

Diagnostic Codes

i02784187

Self-Diagnostics

If a diagnostic lamp illuminates during normal engine

operation, the system has identified a situation that is

not within the specification. Use the electronic service

tool to check the active diagnostic codes.

The electronic  control module has  some

self-diagnostic ability. When an electronic problem

with an input or an output is detected, a diagnostic

code is generated. This indicates the specific problem

with the circuitry.

The active diagnostic code should be investigated.

The cause of the problem should be corrected as

soon as possible. If the cause of the active diagnostic

code is repaired  and there is only one  active

diagnostic code, the diagnostic lamp will turn off.

A diagnostic code which represents a problem that

currently exists is called an active code.

A diagnostic code that is stored in memory is called

a logged code. Always service active codes prior to

servicing logged codes. Logged codes may indicate

intermittent problems.

Operation of the engine and  performance of the

engine can be limited  as a result of the  active

diagnostic code that is generated. Acceleration rates

may be significantly slower and power outputs may

be automatically reduced. Refer to Troubleshooting

, “Troubleshooting with a Diagnostic Code” for more

information on the relationship between each active

diagnostic code and the possible effect on engine

performance.

Logged codes may not  indicate that a repair is

needed. The problems may have been repaired since

the logging of the code. Logged codes may be helpful

to troubleshoot intermittent problems.

i04801080

i02784585

Engine Operation  with

Fault Logging

Intermittent Diagnostic Codes

The system provides the capability of Fault Logging.

When the Electronic  Control Module (ECM)

generates an active diagnostic code, the code will

be logged in the memory of the ECM. The Perkins

electronic service tool can retrieve codes that have

been logged. The codes that have been logged can

be cleared with the Perkins electronic service tool.

If a diagnostic lamp illuminates during normal engine

operation and the diagnostic lamp shuts OFF,  an

intermittent fault may have occurred. If a fault has

occurred, the fault will be logged into the memory of

the Electronic Control Module (ECM).

In most cases, it is not necessary to stop the engine

because of an intermittent  code. However, the

operator should retrieve the  logged fault codes

and the operator should reference the appropriate

information in order to identify the nature of the fault.

The operator should log any observation that could

have caused the lamp to light.

Do not use aerosol types of starting aids such as

ether. Such use could  result in an explosion and

personal injury.

Before the engine is started, perform the  required

daily maintenance  and any other  periodic

maintenance that is due. Refer  to the Operation

and Maintenance Manual, “Maintenance Interval

Schedule” for more information.

The engine will start at  a temperature of −10 °C

(14 °F). The ability to start at temperatures  below

10 °C (50 °F) will improve by the use of a  cylinder

block coolant heater or a device which  heats the

crankcase oil. This will help to reduce white smoke

and misfires when the  engine is started in cold

weather.

•   Open the fuel supply valve (if equipped).

NOTICE

All valves in the fuel return  line must be open before

and during engine operation to help prevent high fuel

pressure. High fuel pressure may cause filter housing

failure or other damage.

If the engine has not been run for several weeks, fuel

may have drained. Air may have moved into the filter

housing. Also, when fuel filters have been changed,

some air will be left in  the filter housing. Refer to

Operation and Maintenance Manual, “Fuel System -

Prime” in order to remove air from the fuel system.

If the engine has not been started for several weeks,

fuel may have drained from  the fuel system. Air

may have entered the filter housing. Also, when fuel

filters have been changed, some air pockets will be

trapped in the engine. In these instances, prime the

fuel system. Refer to the Operation and Maintenance

Manual, “Fuel System - Prime” for more information

on priming the fuel system.

Use the procedure that follows  for cold weather

starting.

After Starting Engine

Note: In temperatures from 0 to 60°C (32 to 140°F),

the warm-up time is approximately three minutes. In

temperatures below 0°C (32°F), additional warm-up

time may be required.

Note: Ensure that the self test  for the monitoring

system (if equipped) is completed before operating

the engine under load.

When the engine idles during warm-up, observe the

following conditions:

•  Check for any fluid or for any air leaks at idle rpm

and at one-half full rpm (no load on the  engine)

before operating the engine under load. This is not

possible in some applications.

•  Operate the engine at low idle until  all systems

achieve operating temperatures. Check all gauges

during the warm-up period.

Note: Gauge readings should be  observed and

the data should be recorded frequently  while the

engine is operating. Comparing the data over time

will help to determine  normal readings for each

gauge. Comparing data over time  will also help

detect abnormal operating developments. Significant

changes in the readings should be investigated.

Engine Operation

The efficiency of the  engine can affect the fuel

economy. Perkins design  and technology in

manufacturing provides maximum fuel efficiency in

all applications. Follow the recommended procedures

in order to attain optimum performance for the life

of the engine.

Correct operation and maintenance are key factors

in obtaining the maximum  life and economy of

the engine. If the directions in  the Operation and

Maintenance Manual are followed, costs can  be

minimized and engine service life can be maximized.

•  Avoid spilling fuel.

Gauge readings should be observed and the data

should be recorded frequently  while the engine

is operating. Comparing the  data over time will

help to determine normal readings for each gauge.

Comparing data over time  will also he, lp detect

abnormal operating developments. Significant

changes in the readings should be investigated.

Fuel expands when the fuel is warmed up. The fuel

may overflow from the fuel tank. Inspect fuel lines for

leaks. Repair the fuel lines, as needed.

•  Be aware of the properties of the different fuels.

Use only the recommended fuels.

•  Avoid unnecessary operation at no load.

Shut off the engine instead of operating the engine

at no load for long periods of time.

•  Observe the service indicator for the air cleaner

frequently, if equipped. Keep  the air cleaner

elements clean.

•  Maintain a good electrical system.

One bad battery cell will overwork the alternator. This

will consume excess power and excess fuel.

•  Ensure that the belts are properly adjusted. The

belts should be in good condition.

•  Ensure that all of the connections of the hoses are

tight. The connections should not leak.

•  Ensure that the driven  equipment is in good

working order.

•  Cold engines consume excess fuel. Keep cooling

system components clean  and keep cooling

system components in good repair. Never operate

the engine without water temperature regulators.

All of these items will  help maintain operating

temperatures.

Cold Weather Operation

Cold Weather Operation

Personal  injury  or property  damage  can  result

from alcohol or starting fluids.

i04564559

Cold Weather Operation

Alcohol or starting fluids are highly flammable and

toxic and if improperly stored could result in injury

or property damage.

Perkins Diesel Engines can operate effectively in

cold weather. During cold weather, the starting and

the operation of the diesel engine is dependent on

the following items:

Do not use aerosol types of starting aids such as

ether. Such use could  result in an explosion and

personal injury.

•  The type of fuel that is used

•  The viscosity of the engine oil

•  Optional Cold starting aid

•  Battery condition

Viscosity of the Engine Lubrication

Oil

Correct engine oil viscosity is essential. Oil viscosity

affects the amount  of torque that  is needed

to crank the  engine. Refer to Operation  and

Maintenance Manual, “Fluid Recommendations” for

the recommended viscosity of oil.

The operation and maintenance of  an engine in

freezing temperatures is complex , because of the

following conditions:

•  Weather conditions

•  Engine applications

Recommendations for the Coolant

Provide cooling system protection for  the lowest

expected outside temperature. Refer to this Operation

and Maintenance Manual, “Fluid Recommendations”

for the recommended coolant mixture.

Recommendations from your Perkins distributor are

based on past proven practices. The information that

is contained in this section provides guidelines for

cold-weather operation.

In cold weather, check the  coolant often for the

correct glycol concentration in  order to ensure

adequate freeze protection.

Hints for Cold Weather Operation

•  If the engine will start, operate the engine until a

minimum operating temperature of 81 °C (177.8 °F)

is achieved. Achieving operating temperature will

help prevent the intake valves and exhaust valves

from sticking.

Coolant Jacket Heaters

If installed, the coolant jacket heater heats the engine

jacket coolant that surrounds the cylinder block. This

added heat provides the following function:

•  The cooling system and the lubrication  system

for the engine do not lose heat immediately upon

shutdown. This means that an engine can be shut

down for a time and the engine can still have the

ability to start readily.

•  Startability is improved.

An electric heater can be activated once the engine

is stopped. An effective heater is typically a  1250

W at 120 V. If your engine  is to operate in a cold

environment, consult your Perkins distributor for more

information. An oil pan heater may also be required.

•  Install the correct specification of engine lubricant

before the beginning of cold weather.

•  Check all rubber parts (hoses, drive belts,) weekly.

•  Check all electrical wiring and connections for any

fraying or damaged insulation.

•  Keep all batteries fully charged and warm.

•  Check the air cleaners and the air intake daily.

Fuel and the Effect from Cold

Weather

Note: Group 3 fuels reduce the life of the engine. The

use of Group 3 fuels is not covered by the Perkins

warranty.

Group 3 fuels include Low Temperature Fuels and

Aviation Kerosene Fuels.

Note: Only use grades of fuel that are recommended

by Perkins. Refer to this Operation and Maintenance

Manual, “Fluid Recommendations”.

Special fuels include Biofuel.

The cloud point is a temperature  that allows wax

crystals to form in the fuel. These crystals can cause

the fuel filters to plug.

The following fuels can be  used in this series of

engine.

•  Group 1

The pour point is the temperature when diesel fuel

will thicken. The diesel fuel becomes more resistant

to flow through fuel lines, fuel filters,and fuel pumps.

•  Group 2

•  Group 3

Be aware of  these facts when  diesel fuel is

purchased. Consider the average  ambient air

temperature for the engine's application. Engines that

are fueled in one climate may not operate well if the

engines are moved to another climate. Problems can

result due to changes in temperature.

•  Special Fuels

Perkins prefer only Group 1 and Group 2 fuels for

use in this series of engines.

Group 1 fuels are the preferred Group of Fuels for

general use by Perkins. Group 1  fuels maximize

engine life and engine performance. Group 1 fuels

are usually less  available than Group 2 fuels.

Frequently, Group 1 fuels are not available in colder

climates during the winter.

Before troubleshooting for low power  or for poor

performance in the winter, check the fuel for waxing.

Low temperature fuels may be available for engine

operation at temperatures below 0 °C (32 °F). These

fuels limit the formation of  wax in the fuel at low

temperatures.

Note: Group 2 fuels must have a  maximum wear

scar of 650 micrometers (HFRR to ISO 12156-1).

For more information on cold weather operation, refer

to the Operation and Maintenance Manual, “Cold

Weather Operation and Fuel Related Components in

Cold Weather”.

Group 2 fuels are considered acceptable for issues

of warranty. This group of fuels may reduce the life

of the engine, the engine's maximum power, and the

engine's fuel efficiency.

When Group 2 diesel fuels are used the  following

components provide a means of minimizing problems

in cold weather:

•  Glow plugs (if equipped)

•  Engine coolant heaters, which may be an OEM

option

•  Fuel heaters, which may be an OEM option

•  Fuel line insulation, which may be an OEM option

There are three major differences between Group

1 fuels and Group 2 fuels. Group 1 fuels  have the

following different characteristics to Group 2 fuels.

•  A lower cloud point

•  A lower pour point

Fuel Related Components in

Cold Weather

Fuel Tanks

Condensation can form in partially filled fuel tanks.

Top off the fuel tanks after you operate the engine.

Fuel tanks should contain some provision for draining

water and sediment from the bottom of the  tanks.

Some fuel tanks use supply pipes that allow water

and sediment to settle below  the end of the fuel

supply pipe.

Some fuel tanks use  supply lines that take fuel

directly from the bottom of the tank. If the engine is

equipped with this system, regular maintenance of

the fuel system filter is important.

Drain the water and sediment from any fuel storage

tank at the following intervals: weekly, oil changes,

and refueling of the fuel tank. This draining will help

prevent water and/or sediment from being pumped

from the fuel storage tank and into the engine fuel

tank.

Fuel Filter

A strainer and fuel filter  is installed between the

fuel tank and the electronic fuel injectors. After you

change the fuel filter, always prime the fuel system

in order to remove air bubbles from the fuel system.

Refer to the Operation and Maintenance Manual in

the Maintenance Section for more information on

priming the fuel system.
