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

Burn Prevention

i05200861

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

aftertreatmentsystem can reach temperatures as

high as 650 °C (1202 °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.

At idle engine speed and/or zero vehicle speed, an

operator can request a manual regeneration. Under

this condition, the exhaust gas temperature can reach

650 °C (1202 °F). Otherwise automatic regeneration

can produce exhaust gas temperatures as high as

650 °C (1202 °F).

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.

Cooling system conditioner contains alkali. Alkali can

cause personal injury. Do not allow alkali to contact

the skin, the eyes, or the mouth.

Allow the engine system to cool before any

maintenance is performed. Relieve all pressure in the

following systems, hydraulic system, lubrication

system, fuel system, and the cooling system before

related items are disconnected.

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.

Contact with high  pressure fuel may  cause fluid

penetration and burn hazards. High pressure fuel

spray may  cause a  fire hazard. Failure  to follow

these  inspection,  maintenance  and  service  in-

structions may cause personal injury or death.

Batteries

Electrolyte is an acid. Electrolyte can cause personal

injury. Do not allow electrolyte to contact the skin or

the eyes. Always wear protective glasses for

servicing batteries. Wash hands after touching the

batteries and connectors. Use of gloves is

recommended.

After the engine has stopped, allow if active the

Engine Stopping

i02234873

Grounding Practices

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 NOTstart 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.

Illustration 11

Typical example

Ground to battery

i04047709

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.

Check the electrical wires daily for wires that are

loose or frayed. Tighten all loose electrical

connections before the engine is started. Repair all

frayed electrical wires before the engine is started.

See the Operation and Maintenance Manual for

specific starting instructions.

Illustration 12

g02324976

Typical example

Alternate ground to battery

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.

Safety Section

Engine Electronics

Uncontrolled electrical circuit paths can result in

damage to the crankshaft bearing journal surfaces

and to aluminum components.

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.

Engines that are installed without engine-to-frame

ground straps can be damaged by electrical

discharge.

Note: Many of the engine control systems and

display modules that are available for Perkins

Engines  will work in unison with the Engine

Monitoring System. Together, the two controls will

provide the engine monitoring function for the specific

engine application. Refer to the Troubleshooting for

more information on the Engine Monitoring System.

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 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.

The power supply connections and the ground

connections for the engine electronics should always

be from the isolator to the battery.

i05181812

Engine Electronics

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 Electronic 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

•   Derate

•   Shutdown

The following monitored engine operating conditions

and components have the ability to limit engine speed

and/or the engine power:

•   Oil Pressure Switch

•   Coolant Temperature Sensor

•   Engine Aftertreatment System

i05139813

The crankshaft for a three cylinder engine has four

main bearing journals. The crankshaft for a four

cylinder engine has five main bearing journals. End

play is controlled by the thrust washers that are

located on the rear main bearing.

Product Description

The 400F models are indirect injection engines. The

fuel injection pump is operated by a solenoid that is

controlled by a Pulse Width Modulation (PWM) signal

from the ECM.

The timing gears are stamped with timing marks in

order to ensure the correct assembly of the gears.

With the timing marks on the crankshaft gear

camshaft gear and the idler gear aligned No. 1 piston

will be at top center compression stroke.

The cylinder head assembly has one inlet valve and

one exhaust valve for each cylinder. Each cylinder

valve has a single valve spring.

The crankshaft gear turns the idler gear which then

turns the camshaft gear and the gear for the engine

oil pump.

The pistons have two compression rings and an oil

control ring. It is important to ensure the correct piston

height so that the piston does not contact the cylinder

head. The correct piston height also ensures efficient

combustion of fuel that is necessary in order to

conform to requirements for emissions.

The fuel injection pump is mounted in the cylinder

block. The fuel injection pump is operated by the

camshaft. The fuel pump is located on the right-hand

side of the cylinder block. The fuel pump is electrically

operated.

Gauges and Indicators

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.

Tachometer – This gauge indicates

engine speed (rpm). When the throttle

control lever is moved to the full throttle

position without load, the engine is running at

high idle. The engine is running at the full load

rpm when the throttle control lever is at the full

throttle position with maximum rated load.

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 dealer

or your Perkins  distributor for assistance.

NOTICE

To  help prevent  engine damage,  never exceed  the

high  idle  rpm. Overspeeding  can  result  in  serious

damage to the engine. The engine can be operated at

high  idle without  damage,  but should  never  be al-

lowed to exceed high idle rpm.

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

predetermined reduction in engine power.

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.

“Shutdown”

The orange warning will be “Flashing” . After the

warning, the engine power will be derated. The

engine will continue at the rpm of the set derate until a

shutdown of the engine occurs. After shutdown the

red stop lamp will illuminate. The engine can be

restarted after a shutdown for use in an emergency.

The following parameters are monitored:

•   Coolant temperature

•   Intake manifold air pressure

•   Oil pressure

A shutdown of the engine after been triggered is

immediate. The engine can be restarted after a

shutdown for use in an emergency. However, the

cause of the initial shutdown may still exist.

•   Engine speed/timing

If there is a signal for high coolant temperature, there

will be a 2 second delay in order to verify the

condition.

•   Atmospheric pressure (Barometric pressure) if

equipped

•   The amount of soot in the Diesel particulate filter

If there is a signal for low oil pressure, there will be a

2 second delay in order to verify the condition.

Fault Logging

i04053178

Self-Diagnostics

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 codes that

have been logged by the ECM can be identified by

the electronic service tool. The active codes that have

been logged will be cleared when the fault has been

rectified or the fault is no longer active.

Perkins  electronic engines have the capability to

perform a self-diagnostics test. When the system

detects an active problem, a diagnostic lamp is

activated. Diagnostic codes will be stored in

permanent memory in the Electronic Control Module

(ECM). The diagnostic codes can be retrieved by

using the electronic service tool. Refer to

Troubleshooting, “Electronic Service Tools” for further

information.

i05182507

Engine Operation with Active

Diagnostic Codes

Some installations have electronic displays that

provide direct readouts of the engine diagnostic

codes. Refer to the manual that is provided by the

OEM for more information on retrieving engine

diagnostic codes. Alternatively refer to

Troubleshooting, “Indicator Lamps” for further

information.

If a diagnostic lamp illuminates during normal engine

operation, the system has identified a situation that is

not within the specification. Use electronic service

tools to check the active diagnostic codes.

Active codes represent problems that currently exist.

These problems should be investigated first.

Note: The power will be limited until the problem is

corrected. If the oil pressure is within the normal

range, the engine may be operated at the rated

speed and load. However, maintenance should be

performed as soon as possible.

Logged codes represent the following items:

•   Intermittent problems

•   Recorded events

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

When Group 2 diesel fuel is used, the following items

provide a means of minimizing starting problems and

fuel problems in cold weather: Engine oil pan heaters,

jacket water heaters, fuel heaters and fuel line

insulation.

•   Ensure that the engine has an adequate fuel

supply.

Use the procedure that follows for cold weather

starting.

•   Open the fuel supply valve (if equipped).

Note: Do not adjust the engine speed control during

start-up. The electronic control module (ECM) will

control the engine speed during start-up.

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. Also, check that the fuel

specification is correct and that the fuel condition  is

correct. Refer to the Operation and Maintenance

Manual, “Fuel Recommendations”.

1. Disengage any driven equipment.

Note: During key ON, the indicator lamps will be

illuminated for 2 seconds in order to check the lamp

operation. If any of the indicator lamps do not

illuminate check the bulb. If any indicator lamps stay

illuminated or flash, refer to Troubleshooting,

“Indicator Lamp Circuit - Test”.

2. Turn the keyswitch to the RUN position. Leave the

keyswitch in the RUN position until the warning

light for the glow plugs is extinguished.

Engine exhaust contains products of combustion

which may be harmful to your health. Always start

Starting the Engine

Improper jump start cable connections can cause

an explosion resulting in personal injury.

Do not use aerosol types of starting aids such as

ether. Such use  could result in an explosion and

personal injury.

Prevent sparks  near the  batteries. Sparks  could

cause vapors to explode. Do not allow jump start

cable ends to contact each other or the engine.

Note: Do not adjust the engine speed control during

start-up. The electronic control module (ECM) will

control the engine speed during start-up.

Note: If it is possible, first diagnose the reason for the

starting failure. Refer to Troubleshooting, “Engine Will

Not Crank and Engine Cranks But Will Not Start” for

further information. Make any necessary repairs. If

the engine will not start only due to the condition of

the battery, either charge the battery, or start the

engine by using another battery with jump start

cables.

Starting the Engine

1. Disengage any equipment that is driven by the

engine.

Note: During key ON, the indicator lamps will be

illuminated for 2 seconds in order to check the lamp

operation. If any of the indicator lamps do not

illuminate check the bulb. If any indicator lamps stay

illuminated or flash, refer to Troubleshooting,

“Indicator Lamp Circuit - Test”.

2. Turn the keyswitch to the RUN position. Leave the

keyswitch in the RUN position until the warning

light for the glow plugs is extinguished.

The condition of the battery can be rechecked after

the engine has been switched OFF.

NOTICE

Using a battery source with  the same voltage as the

electric starting  motor. Use  ONLY equal  voltage for

jump starting. The use of higher  voltage will damage

the electrical system.

Do not reverse the battery cables. The alternator can

be damaged.  Attach ground  cable last  and remove

first.

3. When the warning light for the glow plugs has been

extinguished turn the keyswitch to the START

position. The starter motor will then crank the

engine.

Turn all  electrical accessories OFF  before attaching

the jump start cables.

Ensure that the main power switch is in the OFF posi-

Engine Starting

After Starting Engine

1. Turn the start switch on the stalled engine to the

OFF position. Turn off all the engine's accessories.

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.

2. Connect one positive end of the jump start cable to

the positive cable terminal of the discharged

battery. Connect the other positive end of the jump

start cable to the positive cable terminal of the

electrical source.

3. Connect one negative end of the jump start cable

to the negative cable terminal of the electrical

source. Connect the other negative end of the

jump start cable to the engine block or to the

chassis ground. This procedure helps to prevent

potential sparks from igniting the combustible

gases that are produced by some batteries.

Note: The engine ECM must be powered before the

starting motor is operated or damage can occur.

4. Start the engine in the normal operating procedure.

Refer to this Operation and Maintenance Manual,

“Starting the Engine”.

5. Immediately after the engine is started, disconnect

the jump start cables in reverse order.

After jump starting, the alternator may not be able to

fully recharge batteries that are severely discharged.

The batteries must be replaced or charged to the

proper voltage with a battery charger after the engine

is stopped. Many batteries which are considered

unusable are still rechargeable. Refer to Operation

and Maintenance Manual, “Battery - Replace” and

Testing and Adjusting Manual, “Battery - Test”.

i01903609

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.

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.

Regeneration

Proper operation and maintenance are key factors in

obtaining the maximum life and economy of the

engine. If the directions in the Operation and

speed.

Maintenance Manual are followed, costs can be

minimized and engine service life can be maximized.

i05145051

The time that is needed for the engine to reach

normal operating temperature can be less than the

time taken for a walk-around inspection of the engine.

Diesel Particulate Filter

Regeneration

The engine can be operated at the rated rpm after the

engine is started and after the engine reaches

operating temperature. The engine will reach normal

operating temperature sooner during a low engine

speed (rpm) and during a low-power demand. This

procedure is more effective than idling the engine at

no load. The engine should reach operating

temperature in a few minutes.

Regeneration

Regeneration is the removal of soot from the Diesel

Particulate Filter (DPF). The Aftertreatment

Regeneration Device (ARD) is used to regenerate the

DPF. The DPF traps both soot and ash. The ash is

removed through a manual cleaning process. Refer

to Operation and Maintenance Manual, “Diesel

Particulate Filter - Clean” for more information on the

service of the DPF.

Avoid excess idling. Excessive idling causes carbon

buildup, engine slobber and soot loading of the

Diesel Particulate Filter (DPF). This excess idling is

harmful to the engine.

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.

Types of Regeneration

Passive Regeneration – The engine conditions are

sufficient for regeneration. The rate of regeneration is

much lower than active regeneration.

Active Regeneration – The engine duty cycle

conditions are not sufficient for passive regeneration

to occur.

Reduction of Particulate Emissions

The Diesel Particulate Filter (DPF) and the

AftertreatmentRegeneration Device (ARD) work

together in order to reduce particulate emissions. The

DPF collects the soot and any ash that is produced

by the combustion in the engine. During regeneration,

the soot is converted into a gas which is released into

the atmosphere. The Ash remains in the DPF until the

ash is cleaned out of the DPF.

Regeneration Indicators

Five Indicators can be affected by the DPF

regeneration.

Note: Amber or yellow Warning Indicator can be use

as a diagnostic Indicator. For more information refer

to this Operation and Maintenance Manual,

“Diagnostic Lamp”.

The temperature of the DPF must be above a

particular value in order for regeneration to occur. The

exhaust gas provides heat for the regeneration

process. There are two types of regeneration:

Regeneration Active – The Indicator is

illuminated during active regeneration.

The Indicator will stay on until the

aftertreatmenthas cooled.

Passive Regeneration – The engine conditions are

sufficient for regeneration. The rate of regeneration is

much lower than active regeneration.

DPF  – This Indicator provides a general

indication of the soot load. The Indicator

is off when the soot load is normal.

Active Regeneration – The engine duty cycle

conditions are not sufficient for passive regeneration

to occur.

Note: If the Indicator is illuminated, a regeneration will

be required.

Regeneration Switch

Ensure that the engine maintenance is carried out at

the correct intervals. A lack of maintenance can result

in illumination of the warning Indicators. For the

correct intervals of maintenance, refer to the

Operation and Maintenance Manual, “Maintenance

The regeneration switch has three position force

regeneration, automatic regeneration, and disable

regeneration.

Note: Some OEMs may have other means of

activating a forced regeneration such as touch screen

interface.

Note: The MIDDLE position of the regeneration

switch is the default position for automatic mode of

regeneration.

Hints for Cold Weather Operation

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

minimum operating temperature of 80° C  (176° F)

is achieved. Achieving operating temperature will

help prevent the intake valves and exhaust valves

from sticking.

i04321989

Cold Weather Operation

•   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 period and the engine can still have the

ability to start readily.

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:

•   The type of fuel that is used

•   The viscosity of the engine oil

•   The operation of the glow plugs

•   Optional Cold starting aid

•   Install the correct specification of engine lubricant

before the beginning of cold weather.

•   Check all rubber parts (hoses, fan drive belts,)

weekly.

•   Check all electrical wiring and connections for any

fraying or damaged insulation.

•   Battery condition

This section will cover the following information:

•   Keep all batteries fully charged and warm.

•   Fill the fuel tank at the end of each shift.

•   Potential problems that are caused by cold-

weather operation

•   Check the air cleaners and the air intake daily.

Check the air intake more often when you operate

in snow.

•   Suggest steps which can be taken in order to

minimize starting problems and operating

problems when the ambient air temperature is

between 0° to−40 °C (32° to 40 °F).

•   Ensure that the glow plugs are in working order.

Refer to Troubleshooting, “Glow Plug Starting Aid-

Test”.

The operation and maintenance of an engine in

freezing temperatures is complex . This complexity is

because of the following conditions:

•   Weather conditions

•   Engine applications

Personal  injury  or  property damage  can  result

from alcohol or starting fluids.

Recommendations from your Perkins dealer or your

Perkins  distributor are based on past proven

practices. The information that is contained in this

section provides guidelines for cold-weather

operation.

Alcohol  or starting  fluids  are  highly  flammable

and toxic and if improperly stored could result in

injury or property damage.

Do not use aerosol types of starting aids such as

ether. Such use  could result in an explosion and

personal injury.

•   For jump starting with cables in cold weather, refer

to the Operation and Maintenance Manual,

“Starting with Jump Start Cables.” for instructions.

Cold Weather Operation

Cold Weather Operation

Viscosity of the Engine Lubrication

Oil

When the engine is operated below normal operating

temperatures, fuel and oil are not completely burned

in the combustion chamber. This fuel and oil causes

soft carbon deposits to form on the valve stems.

Generally, the deposits do not cause problems and

the deposits are burned off during operation at normal

engine operating temperatures.

Correct engine oil viscosity is essential. Oil viscosity

affects the amount of torque that is needed to crank

the engine. Refer to this Operation and Maintenance

Manual, “Fluid Recommendations” for the

recommended viscosity of oil.

When starting and stopping an engine many times

without being operated in order to warm up

completely, the carbon deposits become thicker. This

starting and stopping can cause the following

problems:

Recommendationsfor 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.

•   Free operation of the valves is prevented.

•   Valves become stuck.

In cold weather, check the coolant often for the

correct glycol concentration in order to ensure

adequate freeze protection.

•   Pushrods may become bent.

•   Other damage to valve train components can

result.

Engine Block Heaters

For this reason, when the engine is started, the

engine must be operated until the coolant

temperature is 80° C (176° F) minimum. Carbon

deposits on the valve stems will be kept at a minimum

and the free operation of the valves and the valve

components will be maintained.

Engine block heaters (if equipped) heat the engine

jacket water that surrounds the combustion

chambers. This heat provides the following functions:

•   Startability is improved.

•   Warm up time is reduced.

The engine must be thoroughly warmed in order to

keep other engine parts in better condition. The

service life of the engine will be generally extended.

Lubrication will be improved. There will be less acid

and less sludge in the oil. This condition will provide

longer service life for the engine bearings, the piston

rings, and other parts. However, limit unnecessary

idle time to 10 minutes in order to reduce wear and

unnecessary fuel consumption.

An electric block heater can be activated once the

engine is stopped. A block heater can be 110 V dc or

240 V dc. The output can be 750/1000W. Consult

your Perkins dealer or your Perkins distributor for

more information.

Idling the Engine

When idling after the engine is started in cold

weather, increase the engine rpm from 1000 to 1200

rpm. This idling will warm up the engine more quickly.

Maintaining an elevated low idle speed for extended

periods will be easier with the installation of a hand

throttle. The engine should not be “raced” in order to

speed up the warm-up process.

The Water Temperature Regulator and

Insulated Heater Lines

The engine is equipped with a water temperature

regulator. When the engine coolant is below the

correct operating temperature, jacket water circulates

through the engine cylinder block and into the engine

cylinder head. The coolant then returns to the cylinder

block via an internal passage that bypasses the valve

of the coolant temperature regulator. This ensures

that coolant flows around the engine under cold

operating conditions. The water temperature

regulator begins to open when the engine jacket

water has reached the correct minimum operating

temperature. As the jacket water coolant temperature

rises above the minimum operating temperature, the

water temperature regulator opens further allowing

more coolant through the radiator to dissipate excess

heat.

While the engine is idling, the application of a light

load (parasitic load) will assist in achieving the

minimum operating temperature. The minimum

operating temperature is 80° C (176° F).

Recommendationsfor Coolant

Warm Up

Warm up an engine that has cooled below normal

operating temperatures due to inactivity. This warm

-up should be performed before the engine is

returned to full operation. During operation in very

cold temperature conditions, damage to engine valve

mechanisms can result from engine operation for

short intervals. This damage can happen if the engine

is started and the engine is stopped many times

without being operated in order to warm up

completely.

The progressive opening of the water temperature

regulator operates the progressive closing of the

bypass passage between the cylinder block and

head. This action ensures maximum coolant flow to

the radiator in order to achieve maximum heat

dissipation.

Fuel and the Effect from Cold Weather

Note: Do not restrict the air flow. Restriction of the air

flow can damage the fuel system. Perkins

discourages the use of all air flow restriction devices

such as radiator shutters. Restriction of the air flow

can result in the following: high exhaust

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:

temperatures, power loss, excessive fan usage and

reduction in fuel economy.

A cab heater is beneficial in very cold weather. The

feed from the engine and the return lines from the cab

should be insulated in order to reduce heat loss to the

outside air.

•   Glow plugs (if equipped)

•   Engine coolant heaters, which may be an OEM

option

Recommendationfor Crankcase Breather

Protection

•   Fuel heaters, which may be an OEM  option

•   Fuel line insulation, which may be an OEM  option

Crankcase ventilation gases contain a large quantity

of water vapor. This water vapor can freeze in cold

ambient conditions and can plug or damage the

crankcase ventilation system. If the engine is

operated in temperatures below −25° C  (−13° F),

measures must be taken to prevent freezing and

plugging of the breather system. Insulated hoses and

a heated canister assembly should be installed.

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

•   A higher energy per unit volume of fuel

Consult with your Perkins  dealer or your Perkins

distributer for the recommended breather

components for operation from −25° to -40°C

(−13° to -72.°F).

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

use of Group 3 fuels is not covered by the Perkins

warranty.

i02322217

Group 3 fuels include Low Temperature Fuels  and

Aviation Kerosene Fuels .

Fuel and the Effect from Cold

Weather

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.

Note: Only use grades of fuel that are recommended

by Perkins . Refer to this Operation and Maintenance

Manual, “Fluid Recommendations”.

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.

The following fuels can be used in this series of

engine.

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.

•   Group 1

•   Group 2

•   Group 3

Before troubleshooting for low power or for poor

performance in the winter, check the fuel for waxing.

•   Special Fuels

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.

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.

For more information on cold weather operation, refer

to the Operation and Maintenance Manual, “Cold

Weather Operation and Fuel Related Components in

Cold Weather”.

Note: Group 2 fuels must have a maximum wear scar

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

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 al, low , 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 procedure will help

prevent water and/or sediment from being pumped

from the fuel storage tank and into the engine fuel

tank.

Fuel Filters

The engine must have an in-line fuel filter installed

between the fuel tank and the electric operated fuel

lift pump. 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.

Fuel Heaters

Fuel heaters help to prevent fuel filters from plugging

in cold weather due to waxing.

diesel engines:

•   Boiling

Preferred – Perkins  ELC

•   Freezing

Acceptable – A commercial heavy-duty antifreeze

•   Cavitation of the water pump

that meets ASTM D6210 specifications

For optimum performance, Perkins  recommends a

1:1 mixture of a water/glycol solution.

NOTICE

The  400F   industrial  engines must  be operated

with a 1:1  mixture of water and glycol.  This con-

centration allows the NOx reduction system to op-

erate correctly at high ambient temperatures.

Note: Use a mixture that will provide protection

against the lowest ambient temperature.

Note: 100 percent pure glycol will freeze at a

temperature of −23 °C (−9 °F).

NOTICE

Most conventional antifreezes use ethylene glycol.

Propylene glycol may also be used. In a 1:1 mixture

with water, ethylene and propylene glycol provide

similar protection against freezing and boiling. Refer

to Table 12 and refer to table 13 .

Do not use a commercial coolant/antifreeze that  only

meets the  ASTM  D3306 specification.  This type  of

coolant/antifreeze   is   made   for   light   automotive

applications.

Table 12

Ethylene Glycol

Perkins  recommends a 1:1 mixture of water and
