In order to maintain the correct balance between the

antifreeze and the additives, you must maintain the

recommended concentration of ELC. Lowering the

proportion of antifreeze lowers the proportion of

additive. This action will lower the ability of the

coolant to protect the system from pitting, from

cavitation, from erosion, and from deposits.

When using Perkins ELC, do not use standard SCA's

or SCA filters.

ELC

Perkins  provides ELC for use in the following

applications:

ELC Cooling System Cleaning

•   Heavy-duty spark ignited gas engines

•   Heavy-duty diesel engines

•   Automotive applications

Note: If the cooling system is already using ELC,

cleaning agents are not required to be used at the

specified coolant change interval. Cleaning agents

are only required if the system has been

contaminated by the addition of some other type of

coolant or by cooling system damage.

The anti-corrosion package for ELC is different from

the anti-corrosion package for other coolants. ELC is

an ethylene glycol base coolant. However, ELC

contains organic corrosion inhibitors and antifoam

agents with low amounts of nitrite. Perkins ELC has

been formulated with the correct amount of these

additives in order to provide superior corrosion

protection for all metals in engine cooling systems.

Clean water is the only cleaning agent that is required

when ELC is drained from the cooling system.

Before the cooling system is filled, the heater control

(if equipped) must be set to the HOT position. Refer

to the OEM in order to set the heater control. After the

cooling system is drained and the cooling system is

refilled, operate the engine until the coolant level

reaches the normal operating temperature and until

the coolant level stabilizes. As needed, add the

coolant mixture in order to fill the system to the

specified level.

ELC is available in a premixed cooling solution with

distilled water. ELC is a 1:1 mixture. The Premixed

ELC provides freeze protection to −36 °C  (−33 °F).

The Premixed ELC is recommended for the initial fill

of the cooling system. The Premixed ELC is also

recommended for topping off the cooling system.

Changing to Perkins  ELC

Containers of several sizes are available. Consult

your Perkins  distributor for the part numbers.

To change from heavy-duty antifreeze to the Perkins

ELC, perform the following steps:

engine aftertreatment system can be adversely

affected if oil that is not specified in table 19  is used.

The life of your Aftertreatmentsystem is defined by

the accumulation of ash on the surface of the filter.

Ash is the inert part of the particulate matter. The

system is designed in order to collect this particulate

matter. There is a very small percentage of particulate

matter that is left behind as the soot is burnt. This

matter will eventually block the filter, causing loss of

performance and increased fuel consumption. Most

of the ash comes from the engine oil which is

gradually consumed during normal operation. This

ash is passes through the exhaust. To meet the

•   See the appropriate “Lubricant Viscosities”. Refer

to the illustration 40 in order to find the correct oil

viscosity grade for your engine.

•   At the specified interval, service the engine. Use

new oil and install a new oil filter.

•   Perform maintenance at the intervals that are

specified in the Operation and Maintenance

Manual, “Maintenance Interval Schedule”.

Oil analysis

Some engines may be equipped with an oil sampling

valve. If oil analysis is required, the oil sampling valve

is used to obtain samples of the engine oil. The oil

analysis will complement the preventive maintenance

program.

The oil analysis is a diagnostic tool that is used to

determine oil performance and component wear

rates. Contamination can be identified and measured

by using oil analysis. The oil analysis includes the

following tests:

Illustration 40

g02932046

Lubricant Viscosities

•   The Wear Rate Analysis monitors the wear of the

engines metals. The amount of wear metal and

type of wear metal that is in the oil is analyzed. The

increase in the rate of engine wear metal in the oil

is as important as the quantity of engine wear

metal in the oil.

Supplemental heat is recommended for cold soaked

starts below the minimum ambient temperature.

Supplemental heat may be required for cold soaked

starts that are above the minimum temperature that is

stated, depending on the parasitic load and other

factors. Cold soaked starts occur when the engine

has not been operated for a period of time. This

interval will allow the oil to become more viscous due

to cooler ambient temperatures.

•   Tests are conducted in order to detect

contamination of the oil by water, glycol, or fuel.

Aftermarket Oil Additives

•   The Oil Condition Analysis determines the loss of

the oils lubricating properties. An infrared analysis

is used to compare the properties of new oil to the

properties of the used oil sample. This analysis

allows technicians to determine the amount of

deterioration of the oil during use. This analysis

also allows technicians to verify the performance

of the oil according to the specification during the

entire oil change interval.

Perkins  does not recommend the use of aftermarket

additives in oil. It is not necessary to use aftermarket

additives in order to achieve the engines maximum

service life or rated performance. Fully formulated,

finished oils consist of base oils and of commercial

additive packages. These additive packages are

blended into the base oils at precise percentages in

order to help provide finished oils with performance

characteristics that meet industry standards.

There are no industry standard tests that evaluate the

performance or the compatibility of aftermarket

additives in finished oil. Aftermarket additives may not

be compatible with the finished oils additive package,

which could lower the performance of the finished oil.

The aftermarket additive could fail to mix with the

finished oil. This failure could produce sludge in the

crankcase. Perkins  discourages the use of

aftermarket additives in finished oils.

To achieve the best performance from a Perkins

engine, conform to the following guidelines:

Diesel Fuel Characteristics

Cetane numbers in excess of 45 are normally

expected from current diesel fuel. However, a cetane

number of 40 may be experienced in some territories.

The United States of America is one of the territories

that can have a low cetane value. A minimum cetane

value of 40 is required during average starting

conditions. A fuel with higher cetane number is

recommended for operations at high altitudes or in

cold-weather operations.

Cetane Number

Fuel that has a high cetane number will give a shorter

ignition delay. A high cetane number will produce a

better ignition quality. Cetane numbers are derived for

fuels against proportions of cetane and

heptamethylnonane  in the standard CFR engine.

Refer to ISO 5165 for the test method.

Fuel with a low cetane number can be the root cause

of problems during a cold start.

Viscosity

By using the test methods ASTM D5453, ASTM

D2622, or ISO 20846 ISO 20884, the content of sulfur

in ultra low sulfur (ULSD) fuel must be below 15 PPM

0.0015%. The lubricity of these fuels must not exceed

wear scar diameter of 0.52 mm (0.0205 inch). The

fuel lubricity test must be performed on an HFRR,

operated at 60 °C (140 °F). Refer to ISO 12156-1.

Viscosity is the property of a liquid of offering

resistance to shear or flow. Viscosity decreases with

increasing temperature. This decrease in viscosity

follows a logarithmic relationship for normal fossil

fuel. The common reference is to kinematic viscosity.

kinematic viscosity is the quotient of the dynamic

viscosity that is divided by the density. The

determination of kinematic viscosity is normally by

readings from gravity flow viscometers at standard

temperatures. Refer to ISO 3104 for the test method.

Lubricity

Lubricity is the capability of the fuel to prevent pump

wear. The fluids lubricity describes the ability of the

fluid to reduce the friction between surfaces that are

under load. This ability reduces the damage that is

caused by friction. Fuel injection systems rely on the

lubricating properties of the fuel. Until fuel sulfur limits

were mandated, the fuels lubricity was generally

believed  to be a function of fuel viscosity.

The viscosity of the fuel is significant because fuel

serves as a lubricant for the fuel system components.

Fuel must have sufficient viscosity in order to

lubricate the fuel system in both extremely cold

temperatures and extremely hot temperatures . If the

kinematic viscosity of the fuel is lower than “1.4 cSt”

at the fuel injection pump, damage to the fuel injection

pump can occur. This damage can be excessive

scuffing and seizure. Low viscosity may lead to

difficult hot restarting, stalling, and loss of

The lubricity has particular significance to the current

low viscosity fuel , low sulfur fuel, and low aromatic

fossil  fuel. These fuels are made in order to meet

stringent exhaust emissions. A test method for

measuring the lubricity of diesel fuels has been

developed and the test is based on the HFRR method

that is operated at 60°C (140°F). Refer to ISO 12156

pump. If a fuel with a low viscosity is used, cooling of

the fuel may be required to maintain 1.4 cSt or

greater viscosity at the fuel injection pump. Fuels with

a high viscosity might require fuel heaters in order to

lower the viscosity to 4.5 cSt at the fuel injection

pump.

Lubricity wear scar diameter of 0.52 mm

(0.0205 inch) MUST NOT be exceeded. The fuel

lubricity test must be performed on an HFRR,

operated at 60 °C (140 °F). Refer to ISO 12156-1.

Distillation

Density

Distillation is an indication of the mixture of different

hydrocarbons in the fuel. A high ratio of light weight

hydrocarbons can affect the characteristics of

combustion.

Density is the mass of the fuel per unit volume at a

specific temperature. This parameter has a direct

influence on engine performance and a direct

influence on emissions. This influence determines

from a heat output given injected volume of fuel. This

parameter is quoted in the following kg/m at 15 °C

(59 °F).

Recommendation for Biodiesel

Biodiesel is a fuel that can be defined as mono-alkyl

esters of fatty acids . Biodiesel is a fuel that can be

made from various feedstock. The most commonly

available biodiesel in Europe is Rape Methyl Ester

(REM) . This biodiesel is derived from rapeseed oil .

Soy Methyl Ester (SME) is the most common

biodiesel in the United States. This biodiesel is

derived from soybean oil . Soybean oil or rapeseed

oil  are the primary feedstocks. These fuels are

together known as Fatty Acid Methyl Esters (FAME) .

Perkins  recommends a value of density of 841 kg/m

in order to obtain the correct power output. Lighter

fuels are acceptable but these fuels will not produce

the rated power.

Sulfur

The level of sulfur is governed by emissions

legislations . Regional regulation, national

regulations, or international regulations can require a

fuel with a specific sulfur limit. The sulfur content of

the fuel and the fuel quality must comply with all

existing local regulations for emissions.

Refill Capacities

Fluid Recommendations

Raw pressed vegetable oils are NOTacceptable for

use as a fuel in any concentration in compression

engines . Without esterification, these oils solidify in

the crankcase and the fuel tank. These fuels may not

be compatible with many of the elastomers that are

used in engines that are manufactured today. In

original forms, these oils are not suitable for use as a

fuel in compression engines . Alternate base stocks

for biodiesel may include animal tallow, waste

cooking oils , or various other feedstocks. In order to

use any of the products that are listed as fuel, the oil

must be esterified .

Perkins  recognizes the fact that additives may be

required in some special circumstances. Contact your

fuel supplier for those circumstances when fuel

additives are required. Your fuel supplier can

recommend the appropriate fuel additive and the

correct level of treatment.

Note: For the best results, your fuel supplier should

treat the fuel when additives are required. The treated

fuel must meet the requirements that are stated in

table 20 .

Perkins  Diesel Fuel System Cleaner

Fuel made of 100 percent FAME is generally referred

to as B100 biodiesel or neat biodiesel.

Perkins  T400012 Fuel Cleaner is the only fuel

Biodiesel can be blended with distillate diesel fuel.

The blends can be used as fuel. The most commonly

available biodiesel blends are B7, which is 7 percent

biodiesel and 95 percent distillate diesel fuel.

cleaner that is recommended by Perkins .

If biodiesel or biodiesel blends of fuel are to be used,

Perkins  require the use of Perkins  fuel cleaner. The

use of the fuel is in order to remove deposits within

the fuel system that is created with the use of

biodiesel. For more information on the use of

biodiesel and biodiesel blends refer to

Note: The percentages given are volume-based.

The U.S. distillate diesel fuel specification ASTM

D975-09a includes up to B5 (5 percent) biodiesel.

“Recommendation for Biodiesel”.

European distillate diesel fuel specification EN590

includes up B7 (7 percent) biodiesel. Any diesel fuel

in Europe may contain up to B5 or in some regions up

to B7 biodiesel fuel.

Perkins  fuel cleaner will remove deposits that can

form in the fuel system with the use of biodiesel and

biodiesel blends. These deposits can create a loss of

power and engine performance.

Once the fuel cleaner has been added to the fuel, the

deposits within the fuel system are removed after 30

hours of engine operation. For maximum results,

continue to use the fuel cleaner for up to 80 hours.

Perkins  fuel cleaner can be used on an on-going

basis with no adverse impact on engine or fuel

system durability.

Note: Engines that are manufactured by Perkins  are

certified by use of the prescribed Environmental

Protection Agency (EPA) and European Certification

fuels. Perkins does not certify engines on any other

fuel. The user of the engine has the responsibility of

using the correct fuel that is recommended by the

manufacturer and allowed by the EPA and other

appropriate regulatory agencies.

Details instruction on the rate of which the fuel

cleaner must be use are on the container.

Fuel for Cold Weather Operation

Note: Perkins  fuel cleaner is compatible with

existing and U.S. EPATier 4 nonroad certified diesel

engine emission control catalysts and particulate

filters. Perkins  fuel system cleaner contains less

than 15 ppm of sulfur and is acceptable for use with

ULSD fuel.

The European standard EN590 contains climate

dependant requirements and a range of options. The

options can be applied differently in each country.

There are five classes that are given to arctic climates

and severe winter climates . 0, 1, 2, 3 and 4.

Fuel that complies with EN590 CLASS 4 can be used

at temperatures as low as −44 °C (−47.2 °F). Refer

to EN590 for a detailed discretion of the physical

properties of the fuel.

The diesel fuel ASTM D975 1-D used in the United

States of America may be used in very cold

temperatures that are below −18 °C (−0.4 °F).

Aftermarket Fuel Additives

Supplemental diesel fuel additives are not generally

recommended . This recommendation is due to

potential damage to the fuel system or the engine.

Your fuel supplier or the fuel manufacturer will add the

appropriate supplemental diesel fuel additives.

Severe Service Application

i04150276

Severe Service Application

Severe service is the application of an engine that

exceeds the current published standards for that

engine. Perkins  maintains standards for the

following engine parameters:

•   Performance such as power range, speed range,

and fuel consumption

•   Fuel quality

•   Operational Altitude

•   Maintenance intervals

•   Oil selection and maintenance

•   Coolant type and maintenance

•   Environmental qualities

•   Installation

•   The temperature of the fluid in the engine

Refer to the standards for the engine or consult your

Perkins &a, mp;n, bsp;dealer or your Perkins  distributor in order to

determine if the engine is operating within the defined

parameters.

Illustration 41

g01075639

Use the example above. The current flow from the

welder to the ground clamp of the welder will not

damage any associated components.

Severe service operation can accelerate component

wear. Engines that operate under severe conditions

may need more frequent maintenance intervals in

order to ensure maximum reliability and retention of

full service life.

(1) Engine

(2) Welding electrode

(3) Keyswitch in the OFF position

(4) Battery disconnect switch in the open position

(5) Disconnected battery cables

(6) Battery

(7) Electrical/Electronic component

(8) Minimum distance between the component that is being welded

and any electrical/electronic component

(9) The component that is being welded

(10) Current path of the welder

(11) Ground clamp for the welder

Due to individual applications, it is not possible to

identify all of the factors which can contribute to

severe service operation. Consult your Perkins

dealer or your Perkins  distributor for the unique

maintenance that is necessary for the engine.

The operating environment, incorrect operating

procedures, and incorrect maintenance procedures

can be factors which contribute to a severe service

application.

5. When possible, connect the ground clamp for the

welding equipment directly to the engine

component that will be welded. Place the clamp as

close as possible to the weld. Close positioning

reduces the risk of welding current damage to the

engine bearings, to the electrical components, and

to other components.

EnvironmentalFactors

Ambient temperatures – The engine may be

exposed to extended operation in cold environments

or hot environments. Valve components can be

damaged by carbon buildup if the engine is frequently

started and stopped in cold temperatures. Hot intake

air reduces engine performance.

6. Protect the wiring harnesses from welding debris

and/or from welding spatter.

7. Use standard welding procedures to weld the

materials together.

Quality of the air – The engine may be exposed to

extended operation in an environment that is dirty or

dusty, unless the equipment is cleaned regularly.

Mud, dirt, and dust can encase components.

Maintenance can be difficult. The buildup can contain

corrosive chemicals.

Maintenance Recommendations

Alternator and Fan Belts - Inspect/Adjust

Check the alternator and the battery charger for

correct operation. If the batteries are correctly

charged, the ammeter reading should be very near

zero. All batteries should be kept charged. The

batteries should be kept warm because temperature

affects the cranking power. If the battery is too cold,

the battery will not crank the engine. When the engine

is not run for long periods of time or if the engine is

run for short periods, the batteries may not fully

charge. A battery with a low charge will freeze more

easily than a battery with a full charge.

Install the gauge (1) at the center of the belt between

the alternator and the crankshaft pulley and check the

belt tension. The correct tension for a new belt is

400 N (90 lb) to 489 N (110 lb). The correct tension

for a used belt that has been in operation for 30

minutes or more at the rated speed is 267 N  (60 lb) to

356 N (80 lb).

NOTICE

Do not exceed the recommended six percent supple-

mental coolant additive concentration.

A water temperature regulator that fails in the open

position will cause the engine operating temperature

to be too low during partial load operation. Low

engine operating temperatures during partial loads

could cause an excessive carbon buildup inside the

cylinders. This excessive carbon buildup could result

in an accelerated wear of the piston rings and wear of

the cylinder liner.

Use a Coolant Conditioner Test Kit in order to check

the concentration of the SCA.

Add the SCA, If Necessary

NOTICE

NOTICE

Failure to  replace your  water temperature  regulator

on a  regularly scheduled  basis could  cause severe

engine damage.

Do not exceed the  recommended amount of supple-

mental coolant additive concentration. Excessive sup-

plemental  coolant  additive  concentration  can  form

deposits on  the  higher temperature surfaces  of the

cooling system,  reducing the  engine's heat  transfer

characteristics.  Reduced heat  transfer  could cause

cracking of the cylinder head and other high tempera-

ture  components.  Excessive  supplemental  coolant

additive  concentration could  also  result  in  radiator

tube blockage, overheating, and/or accelerated water

pump seal wear. Never use  both liquid supplemental

coolant additive and the spin-on element (if equipped)

at the same time. The use of those additives together

could result in supplemental coolant additive concen-

tration exceeding the recommended maximum.

Perkins

engines incorporate a shunt design cooling

system and require operating the engine with a water

temperature regulator installed.

If the  water temperature regulator  is installed  incor-

rectly,  the  engine  may  overheat,  causing  cylinder

head damage.  Ensure that  the new water  tempera-

ture regulator is installed  in the original position. En-

sure that the water temperature regulator vent hole is

open.

Do not use liquid gasket material on the gasket or cyl-

inder head surface.

NOTICE

Perform this maintenance with the engine stopped.

Contaminants may  cause rapid wear and  shortened

component life.

Do not drain the oil when the engine is cold. As the oil

cools, suspended waste particles settle on the bottom

of the oil pan. The waste particles are not removed

with the draining cold oil. Drain the crankcase with the

engine stopped. Drain the crankcase with the oil

warm. This draining method allows the waste

particles that are suspended in the oil to be drained

correctly.

Note: Oil gauge (A) or oil gauge (B) may be installed

in the engine.

1. Maintain the oil level between “ADD” mark (Y) and

“FULL” mark (X) on oil level gauge (1). Do not fill

the crankcase above “FULL”  mark (X).

NOTICE

Failure to follow this recommended procedure will

cause the waste particles to be recirculated through

the engine lubrication system with the new oil.

Operating your engine when the oil level is above the

“FULL”  mark could cause your crankshaft to dip into

the oil.  The air bubbles  created from the  crankshaft

dipping into the oil  reduces the oil's lubricating char-

acteristics and could result in the loss of power.

Drain the Engine Oil

After the engine has been run at the normal operating

temperature, stop the engine. Use one of the

following methods to drain the engine crankcase oil:

2. Remove the oil filler cap and add oil, if necessary.

Work carefully around an  engine that is running.

Engine parts that  are hot, or  parts that are mov-

ing, can cause personal injury.

Make  sure  that  you wear  eye  protection  at  all

times during testing. When fuel  injection nozzles

are tested, test fluids travel through the orifices of

the  nozzle  tip  with   high  pressure.  Under  this

amount of pressure,  the test fluid can  pierce the

skin and cause serious injury to the  operator. Al-

ways  keep  the  tip  of  the  fuel  injection  nozzle

pointed away from the  operator and into the fuel

collector and extension.

NOTICE

If  your skin  comes  into contact  with high  pressure

fuel, obtain medical assistence immediately.

NOTICE

If a fuel  injector is suspected of operating  outside of

normal parameters it  should be removed by  a quali-

fied technician.  The suspect  fuel injector  should be

taken to an authorised agent for inspection.

NOTICE

Do not allow dirt to enter the fuel system. Thoroughly

clean the area around a  fuel system component that

will be disconnected. Fit a suitable cover over discon-

nected fuel system component.

Operate the engine at a fast idle speed in order to

identify the faulty fuel injector. Individually loosen and

tighten the union nut for the high pressure pipe to

each fuel injector. Do not loosen the union nut more

than half a turn. There will be little effect on the

engine speed when the union nut to the faulty fuel

injector is loosened.

Regular maintenance of the fuel injectors is

recommended by Perkins . The fuel injectors must be

removed and tested by an authorized agent. The fuel

injectors should not be cleaned as cleaning with

incorrect tools can damage the nozzle. The fuel

injectors should be renewed only if a fault with the

fuel injectors occurs. Some of the problems that may

indicate that new fuel injectors are needed are listed

below:

Fuel Tank Water and Sediment - Drain

6. Fasten the assembly to the fuel filter base with

setscrew (2).

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

maintenance of the fuel system filter is important.

Fuel Storage Tanks

i02335436

Drain the water and the sediment from the fuel

storage tank at the following intervals:

Fuel Tank Water and Sediment

- Drain

•   Weekly

•   Service intervals

•   Refill of the tank

NOTICE

Care  must be  taken to  ensure  that fluids  are  con-

tained  during   performance  of  inspection,   mainte-

nance, testing, adjusting and repair of the product. Be

prepared to  collect the fluid  with suitable containers

before  opening any  compartment  or disassembling

any component containing fluids.

This will help prevent water or sediment from being

pumped from the storage tank into the engine fuel

tank.

If a bulk storage tank has been refilled or moved

recently, allow adequate time for the sediment to

settle before filling the engine fuel tank. Internal

baffles in the bulk storage tank will also help trap

sediment. Filtering fuel that is pumped from the

storage tank helps to ensure the quality of the fuel.

When possible, water separators should be used.

Dispose of all fluids according to local regulations and

mandates.

Fuel Tank

Fuel quality is critical to the performance and to the

service life of the engine. Water in the fuel can cause

excessive wear to the fuel system.

i05154415

Glow Plugs (ARD Combustion)

- Replace

Water can be introduced into the fuel tank when the

fuel tank is being filled.

Condensation occurs during the heating and cooling

of fuel. The condensation occurs as the fuel passes

through the fuel system and the fuel returns to the

fuel tank. This causes water to accumulate in fuel

tanks. Draining the fuel tank regularly and obtaining

fuel from reliable sources can help to eliminate water

in the fuel.

Ensure that all adjustments and repairs are

performed by authorized personnel that have the

correct training.

Drain the Water and the Sediment

Fuel tanks should contain some provision for draining

water and draining sediment from the bottom of the

fuel tanks.

Open the drain valve on the bottom of the fuel tank in

order to drain the water and the sediment. Close the

drain valve.

Check the fuel daily. Allow five minutes after the fuel

tank has been filled before draining water and

sediment from the fuel tank.

Fill the fuel tank after operating the engine in order to

drive out moist air. This will help prevent

condensation. Do not fill the tank to the top. The fuel

expands as the fuel gets warm. The tank may

overflow.

Maintenance Recommendations

Radiator - Clean

The coolant system and the hoses for the coolant

system are not usually supplied by Perkins . The

following text describes a typical method of replacing

coolant hoses. Refer to the OEM information for

further information on the coolant system and the

hoses for the coolant system.

Note: Adjust the frequency of cleaning according to

the effects of the operating environment.

Inspect the radiator for these items: Damaged fins,

corrosion, dirt, grease, insects, leaves, oil and other

debris. Clean the radiator, if necessary.

Pressurized System: Hot coolant can  cause seri-

ous burns. To open the cooling system filler cap,

stop the engine and wait until the cooling system

components are cool. Loosen the cooling system

pressure   cap  slowly   in  order   to   relieve  the

pressure.

Personal injury can result from air pressure.

Personal injury can result without following prop-

er  procedure. When  using  pressure air,  wear  a

protective face shield and protective clothing.

Maximum air pressure at the nozzle must be less

than 205 kPa (30 psi) for cleaning purposes.

1. Stop the engine. Allow the engine to cool.

Pressurized air is the preferred method for removing

loose debris. Direct the air in the opposite direction to

the fan's air flow. Hold the nozzle approximately 6 mm

(0.25 inch) away from the radiator fins. Slowly move

the air nozzle in a direction that is parallel with the

radiator tube assembly. This will remove debris that is

between the tubes.

2. Loosen the cooling system filler cap slowly in order

to relieve any pressure. Remove the cooling

system filler cap.

Note: Drain the coolant into a suitable, clean

container. The coolant can be reused.

Pressurized water may also be used for cleaning. The

maximum water pressure for cleaning purposes must

be less than 275 kPa (40 psi). Use pressurized water

in order to soften mud. Clean the core from both

sides.

3. Drain the coolant from the cooling system to a level

that is below the hose that is being replaced.

4. Remove the hose clamps.

5. Disconnect the old hose.

Use a degreaser and steam for removal of oil and

grease. Clean both sides of the core. Wash the core

with detergent and hot water. Thoroughly rinse the

core with clean water.

6. Replace the old hose with a new hose.

7. Install the hose clamps with a torque wrench.

If the radiator is blocked internally, refer to the OEM

Manual for information regarding flushing the cooling

system.

Note: For the correct coolant, see this Operation and

Maintenance Manual, “Fluid Recommendations”.

8. Refill the cooling system. Refer to the OEM

information for further information on refilling the

cooling system.

After cleaning the radiator, start the engine. Allow the

engine to operate at low idle speed for three to five

minutes. Accelerate the engine to high idle. This will

help in the removal of debris and the drying of the

core. Slowly reduce the engine speed to low idle and

then stop the engine. Use a light bulb behind the core

in order to inspect the core for cleanliness. Repeat

the cleaning, if necessary.

9. Clean the cooling system filler cap. Inspect the

cooling system filler cap's seals. Replace the

cooling system filler cap if the seals are damaged.

Install the cooling system filler cap.

Inspect the fins for damage. Bent fins may be opened

with a “comb”. Inspect these items for good condition:

Welds, mounting brackets, air lines, connections,

clamps and seals. Make repairs, if necessary.

10. Start the engine. Inspect the cooling system for

leaks.

Maintenance Recommendations

Radiator Pressure Cap - Clean/Replace

i03639888

Radiator Pressure Cap - Clean/

Replace

A regular visual inspection of the turbocharger is

recommended. Any fumes from the crankcase are

filtered through the air inlet system. Therefore, by-

products from oil and from combustion can collect in

the turbocharger compressor housing. Over time, this

buildup can contribute to loss of engine power,

increased black smoke and overall loss of engine

efficiency.

If the turbocharger fails during engine operation,

damage to the turbocharger compressor wheel and/

or to the engine may occur. Damage to the

turbocharger compressor wheel can cause additional

damage to the pistons, the valves, and the cylinder

head.

Pressurized System: Hot coolant can  cause seri-

ous burns. To open the cooling system filler cap,

stop the engine and wait until the cooling system

components are cool. Loosen the cooling system

pressure   cap  slowly   in  order   to   relieve  the

pressure.

NOTICE

Turbocharger bearing failures can cause large quanti-

ties of oil to enter the air intake and exhaust systems.

Loss of engine lubricant can  result in serious engine

damage.

NOTICE

When any  servicing or  repair of  the engine  cooling

system  is  performed  the  procedure  must  be  per-

formed with the engine on level ground. This will allow

you to accurately check the coolant level. This will al-

so help in avoiding  the risk of introducing an air lock

into the coolant system.

Minor  leakage of  oil  into a  turbocharger under  ex-

tended low idle operation should not cause problems

as  long  as a  turbocharger  bearing  failure has  not

occurred.

When a turbocharger bearing failure is  accompanied

by a  significant loss  of engine  performance, do  not

continue  engine operation  until  the turbocharger  is

renewed.

1. Stop the engine and allow the engine to cool.

Loosen the cooling system filler cap slowly in order

to relieve any pressure. Remove the radiator

pressure cap.

A visual inspection of the turbocharger can minimize

unscheduled downtime. A visual inspection of the

turbocharger can also reduce the chance for potential

damage to other engine parts.

2. Check coolant level. Refer to Operation and

Maintenance Manual, “Cooling System Coolant

Level - Check”.

3. Install new radiator pressure cap.

Removal and Installation

For options regarding the removal, installation, and

replacement, consult your Perkins  dealer or your

Perkins  distributor. Refer to the Disassembly and

Assembly Manual, “Turbocharger - Remove and

Turbocharger - Install” for further information.

Maintenance Recommendations

Walk-Around Inspection

1. Remove the pipe from the turbocharger exhaust

outlet and remove the air intake pipe to the

turbocharger. Visually inspect the piping for the

presence of oil. Clean the interior of the pipes in

order to prevent dirt from entering during

reassembly.

NOTICE

Accumulated grease and/or oil on an  engine is a fire

hazard. Remove the accumulated grease and oil. Re-

fer to  this Operation and  Maintenance Manual, “En-

gine - Clean” for more information.

2. Check for the presence of oil. If oil is leaking from

the back side of the compressor wheel, there is a

possibility of a failed turbocharger oil seal.

•   Ensure that the cooling system hoses are correctly

clamped and that the cooling system hoses are

tight. Check for leaks. Check the condition of all

pipes.

The presence of oil may be the result of extended

engine operation at low idle. The presence of oil

may also be the result of a restriction of the line for

the intake air (clogged air filters), which causes the

turbocharger to slobber.

•   Inspect the water pump for coolant leaks.

Note: The water pump seal is lubricated by the

coolant in the cooling system. It is normal for a small

amount of leakage to occur as the engine cools down

and the parts contract.

3. Inspect the bore of the housing of the turbine outlet

for corrosion.

Excessive coolant leakage may indicate the need to

replace the water pump seal. For the removal of the

water pump and the installation of water pump and/or

seal, refer to the Disassembly and Assembly Manual,

“Water Pump - Remove and Install” for more

information or consult your Perkins dealer or your

Perkins  distributor.

4. Fasten the air intake pipe and the exhaust outlet

pipe to the turbocharger housing.

i02177973

Walk-Around Inspection

•   Inspect the lubrication system for leaks at the front

crankshaft seal, the rear crankshaft seal, the oil

pan, the oil filters and the rocker cover.

Inspect the Engine for Leaks and

for Loose Connections

•   Inspect the fuel system for leaks. Look for loose

fuel line clamps and/or tie-wraps.

A walk-around inspection should only take a few

minutes. When the time is taken to perform these

checks, costly repairs and accidents can be avoided.

•   Inspect the piping for the air intake system and the

elbows for cracks and for loose clamps. Ensure

that hoses and tubes are not contacting other

hoses, tubes, wiring harnesses, etc.

For maximum engine service life, make a thorough

inspection of the engine compartment before starting

the engine. Look for items such as oil leaks or coolant

leaks, loose bolts, worn belts, loose connections and

trash buildup. Make repairs, as needed:

•   Inspect the alternator belts and any accessory

drive belts for cracks, breaks or other damage.

Belts for multiple groove pulleys must be replaced as

matched sets. If only one belt is replaced, the belt will

carry more load than the belts that are not replaced.

The older belts are stretched. The additional load on

the new belt could cause the belt to break.

•   The guards must be in the correct place. Repair

damaged guards or replace missing guards.

•   Wipe all caps and plugs before the engine is

serviced in order to reduce the chance of system

contamination.

NOTICE

For any type of  leak (coolant, lube, or fuel)  clean up

the fluid.  If leaking is  observed, find the source  and

correct the leak. If leaking is suspected, check the flu-

id levels more often than recommended until the leak

is found  or fixed,  or until  the suspicion  of a  leak is

proved to be unwarranted.

Warranty Information

Emissions Warranty Information

Efficiency of the emission control and the engine

performance depends on adherence to proper

operation and maintenance recommendations and

use of recommended fuels and lubricating oils.

According to recommendations, major adjustments

and repairs should be made by your authorized

Perkins  distributor or your authorized Perkins

dealer.

fuel consumption, black smoke, misfire and rough

running engine. The fuel injector should be inspected,

tested, and replaced, if necessary. Fuel injectors can

be tested by an authorized Perkins distributor/dealer

.

TURBOCHARGER – Refer to this Operation and

Maintenance Manual, “Turbocharger - Inspect” for

information on inspection of the turbocharger.

Various chemical fuel additives which claim to reduce

visible smoke are available commercially. Although

additives have been used to solve some isolated

smoke problems in the field, additives are not

recommended for general use. The engines should

be certified without smoke depressants according to

federal smoke regulations.

ELECTRONIC ENGINE CONTROL (ECM) – The

ECM is the control computer of the engine. The ECM

provides power to the electronics. The ECM monitors

data that is input from the sensors of the engine. The

ECM acts as a governor in order to control the speed

and the power of the engine.

Take corrective steps immediately after worn parts

which may affect the emissions level are discovered

in order to ensure the proper operation of the

emission control systems. The use of genuine

Perkins  components is recommended. If the owner

uses non-Perkins  components, then the non-Perkins

components must not adversely affect the emissions

level  of the engine.

Erratic behavior of the engine may indicate a need for

repair to the ECM. Your Perkins distributor/dealer is

equipped with the necessary tools, personnel, and

procedures in order to perform this service.

The owner is encouraged to keep adequate

maintenance records. However, the absence of such

records will not invalidate the warranty. Refer to the

Operation and Maintenance Manual, “Maintenance

Log” (Reference Materials Section).

For information on the use of Aftermarket Products

and Perkins  Engines, refer to this Operation and

Maintenance Manual, “Engine Description”.

The owner may perform routine maintenance, repairs,

and other work that is outside of the warranty. The

work may be done at any repair facility. Such work

does not need to be performed at a designated

station that is determined by the warranty in order for

the warranty to remain in force.

Regular maintenance intervals with a special

emphasis on the following items are necessary in

order to keep exhaust emissions within acceptable

limits for the useful life of the engine. Refer to the

Operation and Maintenance Manual, “Severe Service

Application - Check” topic (Maintenance Section). If

the engine is operating under severe conditions,

adjust the maintenance schedule accordingly. See

your authorized Perkins distributor/dealer in order to

help analyze your specific application, operating

environment, and maintenance schedule

adjustments.

The following information is an explanation of

maintenance items for emission-related components.

See the Operation and Maintenance Manual,

“Maintenance Interval Schedule” (Maintenance

Section) for the specific interval for the following

items.

ENGINE AFTERTREATMENT SYSTEM – The

Engine Aftertreatment Systems are sensitive to the

type of fuel and lubricants that is used. Also, the

engine aftertreatment systems are sensitive to the

operating schedule. Low quality fuel, lubricants, or

fluids may cause increases in exhaust back pressure

or clogging resulting in loss of power. An authorized

Perkins distributor/dealer can determine if the engine

aftertreatmentsystems require a service.

NOx Reduction System (NRS) – The NRS is

monitored. An authorized Perkins distributor/dealer

can determine if the NRS needs service.

FUEL INJECTORS – Fuel injector tips are subject to

wear as a result of fuel contamination. This damage

can cause the following conditions: an increase in
