READ THIS MANUAL carefully to learn how to operate
and service your engine correctly. Failure to do so
could result in personal injury or equipment damage.
THIS MANUAL SHOULD BE CONSIDERED a
permanent part of your engine and should remain with
the engine when you sell it.
MEASUREMENTS IN THIS MANUAL are given in both
metric and customary U.S. unit equivalents. Use only
correct replacement parts and fasteners. Metric and
inch fasteners may require a specific metric or inch
wrench.
WRITE ENGINE SERIAL NUMBERS and option codes
in the spaces indicated in the Record Keeping Section.
Accurately record all the numbers. Your dealer also
needs these numbers when you order parts. File the
identification numbers in a secure place off the engine.
SETTING FUEL DELIVERY beyond published factory
specifications or otherwise overpowering will result in
loss of warranty protection for this engine.
CERTAIN ENGINE ACCESSORIES such as radiator,
air cleaner, and instruments are optional equipment on
John Deere OEM Engines. These accessories may be
provided by the equipment manufacturer instead of
John Deere. This operator’s manual applies only to the
engine and those options available through the John
Deere distribution network.

Engine Option Codes
A—Engine Base Code
In addition to the serial number plate, OEM engines
have an engine option code label affixed to the rocker
arm cover. These codes indicate which of the engine
options were installed on your engine at the factory.
When in need of parts or service, furnish your
authorized servicing dealer or engine distributor with
these numbers.
The engine option code label includes an engine base
code (A). This base code must also be recorded along
with the option codes.
The first two digits of each code identify a specific
group, such as alternators. The last two digits of each
code identify one specific option provided on your
engine, such as a 12-volt, 55-amp alternator.
NOTE: These option codes are based on the latest
information available at the time of publication.
The right is reserved to make changes at any
time without notice.
If an engine is ordered without a particular component,
the last two digits of that functional group option code
will be 99, 00, or XX. The list on the next page shows
only the first two digits of the code numbers. For future
reference such as ordering repair parts, it is important
to have these code numbers available. To ensure this
availability, enter the third and fourth digits shown on
your engine option code label in the spaces provided
on the following page.

Handling and Storing Diesel Fuel
When using bio-diesel fuel, the fuel filter may require
more frequent replacement due to premature plugging.
CAUTION: Handle fuel carefully. Do not fill
the fuel tank when engine is running.
Check engine oil level daily prior to starting engine. A
rising oil level may indicate fuel dilution of the engine
oil.
DO NOT smoke while you fill the fuel tank or
service the fuel system.
Fill the fuel tank at the end of each day’s operation to
prevent water condensation and freezing during cold
weather.
IMPORTANT: The fuel tank is vented through the
filler cap. If a new filler cap is
required, always replace it with an
original vented cap.
Keep all storage tanks as full as practicable to
minimize condensation.
When fuel is stored for an extended period or if there
is a slow turnover of fuel, add a fuel conditioner to
stabilize the fuel and prevent water condensation.
Contact your fuel supplier for recommendations.
Ensure that all fuel tank caps and covers are installed
properly to prevent moisture from entering.

handling of bio-diesel fuel especially important. Areas
of concern include:
It is recommended to purchase bio-diesel fuel blended
with B100 from a BQ-9000 Accredited Producer or a
BQ-9000 Certified Marketer as recommended by the
National Bio-diesel Board.
• Quality of new fuel
• Water content of the fuel
• Problems due to aging of the fuel
The maximum allowable bio-diesel concentration is a
5% blend (also known as B5) in petroleum diesel fuel.
It has been found that bio-diesel fuels may improve
lubricity in concentrations up to this 5% blend.
Potential problems resulting from deficiencies in the
above areas when using bio-diesel fuel in
concentrations above 5% may lead to the following
symptoms:
When using a blend of bio-diesel fuel, the engine oil
level must be checked daily when the air temperature
is –10°C (14°F) or lower. If oil becomes diluted with
fuel, shorten oil change intervals accordingly.

•
IMPORTANT: Raw pressed vegetable oils are NOT
acceptable for use as fuel in any
concentration in John Deere
engines.
•
•
•
•
These oils do not burn completely,
and will cause engine failure by
Power loss and deterioration of performance
Fuel leakage
Corrosion of fuel injection equipment
Coked and/or blocked injector nozzles, resulting in
engine misfire
Filter plugging
Lacquering and/or seizure of internal components
Sludge and sediments
Reduced service life of engine components
Consult your fuel supplier for additives to improve
storage and performance of bio-diesel fuels.

Minimizing the Effect of Cold Weather on Diesel Engines
John Deere diesel engines are designed to operate
effectively in cold weather.
However, for effective starting and cold weather
operation, a little extra care is necessary. The
information below outlines steps that can minimize the
effect that cold weather may have on starting and
operation of your engine. See your John Deere dealer
for additional information and local availability of cold
weather aids
Use Winter Grade Fuel
When temperatures fall below 5°C (40°F), winter grade
fuel (Grade No. 1-D fuel in North America) is best
suited for cold weather operation. Winter grade fuel
has a lower cloud point and a lower pour point.
Cloud point is the temperature at which wax will begin
to form in the fuel and this wax causes fuel filters to
plug. Pour point is the temperature at which fuel
begins to thicken and becomes more resistant to flow
through fuel pumps and lines.
NOTE: On an average, winter grade fuel has a lower
BTU (heat content) rating. Using winter grade
fuel may reduce power and fuel efficiency, but
should not cause any other engine
performance effects. Check the grade of fuel
being used before troubleshooting for low
power complaints in cold weather operation.
Air Intake Heater
An air intake heater is an available option to aid cold
weather starting.
CAUTION: Do not use any starting fluid with
an air intake heater.
CAUTION: Do not use any starting fluid with
an engine equipped with glow plugs
Coolant Heater
An engine block heater (coolant heater) is an available
option to aid cold weather starting.
Seasonal Viscosity Oil and Proper Coolant
Concentration
Use seasonal grade viscosity engine oil based ion the
expected air temperature range between oil changes
and proper concentration of low silicate antifreeze as
recommended. (See DIESEL ENGINE OIL and
ENGINE COOLANT requirements this section.)
Diesel Fuel Flow Additive
Use John Deere Premium Diesel Fuel Conditioner
(Winter) or equivalent to treat fuel during the cold
weather season. This winter formulation is a
combination diesel fuel conditioner and anti-gel
additive.
IMPORTANT: Treat fuel when outside temperature
drops below 0°C (32°F). For best
results, use with untreated fuel.
Follow all recommended instructions
on label.
Winterfronts
Use of fabric, cardboard , or solid winterfronts is not
recommended with any John Deere engine. Their use
can result in excessive engine coolant, oil, and charge
air temperatures. This can lead to reduced engine life,
loss of power and poor fuel economy. Winterfronts
may also put abnormal stress on fan and fan drive
components potentially causing premature failures.
Starting Fluid
A starting fluid port on the intake is available to aid
cold weather starting.

Fuels, Lubricants, and Coolant
If winterfronts are used, they should never totally close
off the grill frontal area. Approximately 25% area in the
center of the grill should remain open at all times. At
no time should the air blockage device be applied
directly to the radiator core.
Radiator Shutters
If equipped with a thermostatically controlled radiator
shutter system, this system should be regulated in
such a way that the shutters are completely open by
the time the coolant reaches 93°C (200°F) to prevent
excessive intake manifold temperatures. Manually
controlled systems are not recommended.
If air-to-air aftercooling is used, the shutters must be
completely open by the time the intake manifold air
temperature reaches the maximum allowable
temperature out of the charge air cooler.
For more information, see your John Deere dealer.

Diesel Engine Oil and Filter Service Intervals
The oil and filter service intervals in the following
charts should be used as guidelines. Actual service
intervals depend on operation and maintenance
practices. Use oil analysis to determine the actual
useful life of the oil and to aid in selection of the
proper oil and filter service interval.
Refer to the charts on the following pages to find the
proper oil and filter service interval for your engine.
Using Charts to Find Oil and Filter Service Interval
1. Determine your engine model and power rating and
find it in the left column of 4.5 L or 6.8 L chart.
Oil and filter service intervals are based on a
combination of oil pan capacity, type of engine oil and
filter used, and sulfur content of the diesel fuel.
2. Locate your engine oil pan option code (19__) on
engine label.
Diesel fuel sulfur level will affect engine oil and filter
service intervals. Higher fuel sulfur levels reduce oil
and filter service intervals as shown in the table:
3. In the chart column under your oil pan code, select
whether you use premium oil (PLUS-50 or
equivalent) or standard grade oil.
• Use of diesel fuel with sulfur content less than
0.05% (500 ppm ) is strongly recommended.
• Use of diesel fuel with sulfur content 0.05% (500
ppm) to 0.50% (5000 ppm) may result in REDUCED
oil and filter change intervals as shown in the table.
• BEFORE using diesel fuel with sulfur content greater
than 0.50% (5000 ppm), contact your John Deere
dealer.
4. Determine the sulfur content of your diesel fuel.
5. Now you can find the proper oil and filter change
interval by lining up your power level and fuel sulfur
content with oil pan/oil type column. The number
indicates how frequent your oil and filter should be
changed (example: every 500 hours of operation).
Oil types (premium or standard) in the tables include:
• “Premium Oils” include John Deere PLUS-50,
ACEA E7, ACEA E6, ACEA E5 or ACEA E4 oils.
• “Standard Oils” include John Deere TORQ-GARD
SUPREME, API CI-4 PLUS, API CI-4, , API CH4
or ACEA E3 oils.
NOTE: The 500 hour extended oil and filter change
interval is allowed only if ALL the following
conditions are met:
• Engine equipped with an oil pan that allows capacity
for this extended drain interval.
• Use of premium oil John Deere PLUS-50, ACEA E7,
ACEA E6, ACEA E5 or ACEA E4
• Use of an approved John Deere oil filter
• Use of diesel fuel with sulfur content less than
0.05% (500 ppm)

Drain Intervals for Diesel Engine Coolant
Drain the factory fill engine coolant, flush the cooling
system, and refill with new coolant after the first 3 years
or 3000 hours of operation.
Subsequent drain intervals are determined by the coolant
used for service. At each interval, drain the coolant, flush
the cooling system, and refill with new coolant.
When John Deere COOL-GARD is used, the drain
interval may be extended to 5 years or 5000 hours of
operation, provided that the coolant is tested annually
AND additives are replenished, as needed, by adding a
supplemental coolant additive.
If John Deere COOL-GARD is used but the coolant is not
tested OR additives are not replenished by adding a
supplemental coolant additive, the drain interval is 3 years
or 3000 hours of operation
If COOL-GARD is not used, the drain interval is reduced
to 2 years or 2000 hours of operation.

Supplemental Coolant Additives
The concentration of coolant additives is gradually
depleted during engine operation. For all
recommended coolants, replenish additives between
drain intervals by adding a supplemental coolant
additive every 12 months or as determined necessary
by coolant testing.
John Deere COOLANT CONDITIONER is
recommended as a supplemental coolant additive in
John Deere engines.
If other coolants are used, consult the coolant supplier
and follow the manufacturer’s recommendation for use
of supplemental coolant additives.
The use of non-recommended supplemental coolant
additives may result in additive drop-out and gelation
of the coolant.
Add the manufacturer’s recommended concentration of
supplemental coolant additive. DO NOT add more than
the recommended amount.
IMPORTANT: Do not add a supplemental coolant
additive when the cooling system is
drained and refilled with John

Testing Diesel Engine Coolant
Testing Diesel Engine Coolant
Maintaining adequate concentrations of glycol and
inhibiting additives in the coolant is critical to protect
the engine and cooling system against freezing,
corrosion, and cylinder liner erosion and pitting.
Test the coolant solution at intervals of 12 months or
less and whenever excessive coolant is lost through
leaks or overheating.
Coolant test strips
Coolant test strips are available from your John Deere
dealer. These test strips provide a simple, effective
method to check the freeze point and additive levels of
your engine coolant.
Compare the results to the supplemental coolant
additive (SCA) chart to determine the amount of
inhibiting additives in your coolant and whether more
John Deere COOLANT CONDITIONER should be
added.
COOLSCAN and COOLSCAN PLUS
For a more thorough evaluation of your coolant,
perform a COOLSCAN or COOLSCAN PLUS analysis,
where available. See your John Deere dealer for
information.

The cancel/resume function is intended for applications
like agricultural tractors and sprayers that turn around at
the end of each row in a field. This allows the operator to
use the throttle and/or brake to turn the vehicle around.
When ready to resume field operations, the operator
brings the engine speed above 1300 rpm and activates
the cancel/resume function again to resume cruise speed.
An internal timer gives the operator one minute to
complete the turnaround maneuver.
The cruise control has the normal functions of:
•
•
•
•
Cruise control power “ON” or “OFF”.
“Set” or “bump up” engine speed.
“Resume” or “bump down” engine speed.
Use vehicle brake or clutch pedal to disengage cruise
control.
The “bump up” and “bump down” speed controls allow the
operator to change the set speed. Small engine speed
changes can be made by “bumping” the control switch.
Holding the “bump up” or “bump down” switch will result in
greater engine rpm changes until the engine reaches
either full speed or idle. The cruise control cannot operate
beyond the normal min/max engine speeds.

This is a three-position switch (H) with the center
position as “OFF” (locked). With this switch in the
“OFF” position, the speed select switch (I) is also
locked, to prevent accidental changes in operating
speed. Pressing upper or lower half of switch (H) will
unlock or enable the bump speed switch to take effect
using speed select switch (I).
I—Speed Select Rocker Switch
The speed select switch (I) is used to bump engine
speed up (+) or down (-) in small increments during
operation. This switch must be used with the bump
speed enable switch (H) in the unlocked position (top
or bottom half of button depressed).
J—High-Low Speed Select Rocker Switch
The high-low speed select switch (J) is used to set the
engine operating speeds at slow (turtle) or fast (rabbit).
Factory preset idle speeds can also be adjusted using
bump speed enable switch (H) with speed select
switch (I).
The basic instrument panel will have the high-low
speed select switch only. Press and hold up (+) or
down (-) to adjust engine speed as desired. The
engine speed selected will not be held in the memory.

Normal Engine Operation
remove load and restart the engine.
Overheating of the turbocharger
parts may occur when oil flow is
stopped.
Observe engine coolant temperature and engine oil
pressure. Temperatures and pressures will vary
between engines and with changing operating
conditions, temperatures, and loads.
Normal engine coolant operating temperature range is
82°—94°C (180°—202°F). If coolant temperature rises
above 112°C (234°F), reduce load on engine. Unless
temperature drops quickly, stop engine and determine
cause before resuming operation.
Engine oil pressure should be at least 103 kPa (1.03
bar) (15 psi) at slow idle and should reach at least 241
kPa (2.41 bar) (35 psi) at rated speed under full load.
Operate the engine under a lighter load and at slower
than normal speed for first 15 minutes after start-up.

Warming Engine
The electronically-controlled engines will operate at an
accelerated slow idle of 1050 rpm until the engine coolant
warms up to 20° C (68° F).
1. Check oil pressure gauge (A) as soon as engine starts.
If gauge needle does not rise above minimum oil
pressure specification of 105 kPa (1.05bar) (15.0 psi)
within 5 seconds, stop the engine and determine the
cause. Normal engine oil pressure is 345 ± 103 kPa
(3.45 ± 1.03 bar) (50 ± 15 psi) at rated full load speed
(1800–2500 rpm) with oil at normal operating
temperature of 115°C (240°F).
RG13281
Engines used in generator set
applications where the governor is
locked at a specified speed may not
have a slow idle function. Operate these
engines at high idle for 1 to 2 minutes
before applying the load. This
procedure does not apply to standby
generator sets where the engine is
loaded immediately upon reaching rated
speed.
–UN–30OCT03
IMPORTANT: To assure proper lubrication, operate
engine at or below 1200 rpm with no
load for 1–2 minutes. Extend this period

Avoid Excessive Engine Idling
Prolonged idling may cause the engine coolant
temperature to fall below its normal range. This, in
turn, causes crankcase oil dilution, due to incomplete
fuel combustion, and permits formation of gummy
deposits on valves, pistons, and piston rings. It also
promotes rapid accumulation of engine sludge and
unburned fuel in the exhaust system.

minutes, stop and restart later.
NOTE: Generator set applications where the governor
is locked at a specified speed may not have a
slow idle function. These engines will idle at no
load governed speed (high idle).
Once an engine is warmed to normal operating

be serviced.
RG7332A
IMPORTANT: Maximum air intake restriction is 6.25
kPa (0.06 bar) (1.0 psi) (25 in. H2O). A
clogged air cleaner element will cause
excessive intake restriction and a
reduced air supply to the engine.

5. Make a thorough inspection of the engine
compartment. Look for oil or coolant leaks, worn fan
and accessory drive belts, loose connections and trash
build-up. Remove trash buildup and have repairs made
as needed if leaks are found.
NOTE: Wipe all fittings, caps, and plugs before
performing any maintenance to reduce the chance
of system contamination.
Inspect:
• Radiator for leaks and trash build-up.
• Air intake system hoses and connections for cracks
and loose clamps.
• Fan, alternator, and accessory drive belts for cracks,
breaks or other damage.
• Coolant pump for coolant leaks.
NOTE: It is normal for a small amount of leakage to occur
as the engine cools down and parts contract.
Excessive coolant leakage may indicate the need
to replace the coolant pump seal. Contact your
engine distributor or servicing dealer for repairs.

Checking Air Compressors (If Equipped)
Air compressors are offered as options with John Deere
OEM engines to provide compressed air to operate
air-powered devices like vehicle air brakes.
Air compressors are engine-driven piston types. They are
either air cooled or cooled with engine coolant. The
compressors are lubricated with engine oil. The
compressor runs continuously as gear or spline driven by
the auxiliary drive of the engine but has “loaded” and
“unloaded” operating modes. This is controlled by the
vehicle’s air system (refer to vehicle technical manual for
complete air system checks and services).
RG12836
–UN–27FEB03
See your John Deere engine distributor or servicing dealer
for diagnostic and troubleshooting information. If diagnosis
leads to an internal fault in the compressor, replace the
complete compressor as a new or remanufactured unit.

Troubleshooting
General Troubleshooting Information
Troubleshooting engine problems can be difficult. An
engine wiring diagram is provided in this section to
help isolate electrical problems on power units using
John Deere wiring harness and instrument (gauge)
panel.
Wiring diagrams are shown for the electronic
instrument panel and harness offered for these
engines.
Later in this section is a list of possible engine
problems that may be encountered accompanied by
possible causes and corrections. The illustrated
diagrams and troubleshooting information are of a
general nature; final design of the overall system for
your engine application may be different. See your
engine distributor or servicing dealer if you are in
doubt.
• Know the engine and all related systems.
• Study the problem thoroughly.
• Relate the symptoms to your knowledge of engine
and systems.
• Diagnose the problem starting with the easiest
things first.
• Double-check before beginning the disassembly.
• Determine cause and make a thorough repair.
• After making repairs, operate the engine under
normal conditions to verify that the problem and
cause was corrected.
NOTE: The engines covered in this manual have
electronic control systems which send
diagnostic trouble codes to signal problems
(see DIAGNOSTIC TROUBLE CODE
PROCEDURE, later in this section).
A reliable program for troubleshooting engine problems
should include the following basic diagnostic thought
process:

Precautions For Welding On Engines
Equipped With Electronic Engine Control
Unit (ECU)
IMPORTANT: ALWAYS disconnect Electronic Control
Unit (ECU) connectors and engine
control system-to-machine ground
before welding on engine or machine.
High currents or electro-static
discharge in electronic components
from welding may cause permanent
damage.
1. Remove the ground connection for the engine control
system-to-machine frame.
2. Disconnect the connectors from the ECU.
3. Connect the welder ground close to the welding point
and be sure ECU or other electronic components are not
in the ground path.

IMPORTANT: Care should be used during diagnostic
procedures to avoid damaging the
terminals of connectors, sensors, and
actuators. Probes should not be poked
into or around the terminals or damage
will result. Probes should only be
touched against the terminals to make
measurements.

Diagnosis of the Deere electronic control system on
engines with Deere electronic instrument panel (shown)
should be performed as follows:
NOTE: Liquid Crystal Display [LCD] will always default to
last menu item. If an active Diagnostic Trouble
Code (DTC) is present, display will alternately
flash from the hour meter reading to DTC(s).

The code number will appear on the first line and
the words SrvcCode on the second line. Active
DTC(s) can be viewed by selecting “SrvcCode” on
the menu and pressing both touch switches at the
same time. Pressing touch switches (B) and (C)
scrolls through various engine parameters and
diagnostic trouble codes.
2. Read and record DTC(s) displayed on LCD of
diagnostic gauge (A). For procedure to access diagnostic
trouble codes, refer to “Using Diagnostic Gauge to Access
Engine Information”, earlier in this manual.
3. Go to the LISTING OF DIAGNOSTIC TROUBLE

Troubleshooting
Displaying Of Diagnostic Trouble Codes (DTCs)
There are several different methods for displaying both
stored and active DTCs from the ECU via a fault lamp
or a diagnostic gauge on the electronic instrument
panel.
The SPN identifies the system or the component that
has the failure; for example SPN 000110 indicates a
failure in the engine coolant temperature circuit.
The FMI identifies the type of failure that has occurred;
for example FMI 03 indicates value above normal.
Combining SPN 000110 with FMI 03 yields engine
coolant temperature input voltage too high, or the
equivalent of 2-digit fault code 18.
2-DIGIT CODES
Some engines display Service Codes or DTCs as
2-digit codes read from a fault lamp which gives blink
codes.
SPN/FMI CODES
Stored and active diagnostic trouble codes are output
on the diagnostic gauge on the Deere electronic
instrument panel according to the J1939 standard as a
two-part code as shown on the tables on the following
pages.
If diagnosing an application that shows DTCs as SPNs
and FMIs, using the following list, determine the
equivalent 2-digit code and have your dealer use the
diagnostic procedure in the component technical
manual for that 2-digit code.
Always contact your servicing dealer for help in
correcting diagnostic trouble codes which are
displayed for your engine.
The first part is a six-digit Suspect Parameter Number
(SPN) followed by a two-digit Failure Mode Identifier
(FMI) code. In order to determine the exact failure,
both parts (SPN and FMI) of the code are needed.

Troubleshooting
Intermittent Fault Diagnostics (With Electronic Controls)
Intermittent faults are problems that periodically “go
away”. A problem such as a terminal that intermittently
doesn’t make contact can cause an intermittent fault.
Other intermittent may be set only under certain
operating conditions such as heavy load, extended
idle, etc. When diagnosing intermittent faults, take
special note of the condition of wiring and connectors,
since a high percentage of intermittent problems
originate here. Check for loose, dirty or disconnected
connectors. Inspect the wiring routing, looking for
possible shorts caused by contact with external parts
(for example, rubbing against sharp sheet metal
edges). Inspect the connector vicinity, looking for wires
that have pulled out of connectors, poorly positioned
terminals, damaged connectors and corroded or
damaged splices and terminals. Look for broken wires,
damaged splices, and wire-to-wire shorts. Use good
judgement if component replacement is thought to be
required.
• If the problem is intermittent, try to reproduce the
operating conditions that were present when the
diagnostic trouble code (DTC) set.
• If a faulty connection or wire is suspected to be the
cause of the intermittent problem: clear DTCs, then
check the connection or wire by wiggling it while
watching the diagnostic gauge to see if the fault
resets.
Possible causes of intermittent faults:
• Faulty connection between sensor or actuator
harness.
• Faulty contact between terminals in connector.
• Faulty terminal/wire connection.
• Electromagnetic interference (EMI) from an
improperly installed 2-way radio, etc., can cause
faulty signals to be sent to the ECU.
NOTE: Refer to wiring diagrams earlier in this section
as a guide to connection and wiring.
NOTE: The engine control unit (ECU) is the
component LEAST likely to fail.
Suggestions for diagnosing intermittent faults:

Storage
Engine Storage Guidelines
1. John Deere engines can be stored outside for up to
three (3) months with no long term preparation IF
COVERED BY WATERPROOF COVERING. No
outside storage is recommended without a
waterproof covering.
2. John Deere engines can be stored in a standard
overseas shipping container for up to three (3)
months with no long term preparation.
3. John Deere engines can be stored inside for up to
six (6) months with no long term preparation.
4. John Deere engines expected to be stored more
than six (6) months MUST have long term storage
preparation. ( See PREPARING ENGINE FOR
LONG TERM STORAGE, later in this section.)
5. Long term storage includes the use of a stabilized
rust preventive oil to protect internal metal
components of the engine. This oil should be an
SAE 10 oil with 1-4 percent morpholine or
equivalent vapor corrosion inhibitor. These rust
preventive oils are available from area distributors.
OURGP12,00000DF –19–27JUL06–1/1

PN=225
Storage
Preparing Engine for Long Term Storage
The following storage preparations are used for long
term engine storage up to one year. After that, the
engine should be started, warmed up, and retreated
for an extended storage period.
IMPORTANT: Any time your engine will not be
used for over six (6) months, the
following recommendations for
storing it and removing it from
storage will help to minimize
corrosion and deterioration.
1. Change engine oil and replace filter. (See CHANGE
ENGINE OIL AND FILTER in Lubrication and
Maintenance/500 Hour Section.) Used oil will not
give adequate protection. Add one (1) ounce of rust
preventive oil to the engine crankcase for every
quart of oil. This rust preventive oil should be an
SAE 10 oil with 1-4 percent morpholine or
equivalent vapor corrosion inhibitor.
2. Service air cleaner. (See REPLACING AIR
CLEANER FILTER ELEMENTS in Service As
Required Section.)
3. Draining and flushing of cooling system is not
necessary if engine is to be stored only for several
months. However, for extended storage periods of a
year or longer, it is recommended that the cooling
system be drained, flushed, and refilled. Refill with
appropriate coolant. (See RECOMMENDED
ENGINE COOLANT in Fuels, Lubricants, and
Coolant Section and ADDING COOLANT in Service
As Required Section.)
4. Pour three (3) ounces of rust preventive oil into the
turbocharger intake. (It may be necessary to
temporarily install a short intake elbow on the
turbocharger inlet to receive the oil.)
6. Remove existing lines/plugs as required, and run a
temporary line from the tank to the engine fuel
intake, and another temporary line from the fuel
return manifold to the tank, so rust preventive oil
solution is circulated through the injection system
during cranking.
7. Crank the engine several revolutions with starter
(do not allow the engine to start). This will allow
rust preventive oil solution to circulate.
8. Remove temporary lines installed in Step 6 above,
and replace any lines/plugs previously removed.
NOTE: One gallon of fuel/oil solution can be used to
treat 100 engines; two gallons to treat 200
engines, etc. The oil could then be replenished
by adding an additional five (5) ounces of rust
preventive oil per gallon of solution. However,
starting over with a new solution is
recommended to dispose of any water or other
impurities.
9. Loosen, or remove and store, fan/alternator
poly-vee belt.
10. Remove and clean batteries. Store them in a cool,
dry place and keep them fully charged.
11. Disengage the clutch for any driveline.
12. Clean the exterior of the engine with salt-free
water and touch up any scratched or chipped
painted surfaces with a good quality paint.
13. Coat all exposed (machined) metal surfaces with
grease or corrosion inhibitor if not feasible to paint.
14. Seal all openings on engine with plastic bags and
tape.
5. Prepare a tank with a solution of diesel fuel and
rust preventive oil, at ten (10) ounces of rust
preventive oil per gallon of diesel fuel.

Storage
15. Store the engine in a dry protected place. If
engine must be stored outside, cover it with a
waterproof canvas or other suitable protective
material and use a strong waterproof tape.
OURGP11,000006C –19–27JUL06–2/2
Removing Engine from Long Term Storage
Refer to the appropriate section for detailed services
listed below or have your authorized servicing dealer
or engine distributor perform services that you may not
be familiar with.
IMPORTANT: DO NOT operate starter more than
30 seconds at a time. Wait at least 2
minutes for starter to cool before
trying again.
1. Remove all protective coverings from engine.
Unseal all openings in engine and remove covering
from electrical systems.
6. Crank engine for 20 seconds with starter (do not
allow the engine to start). Wait 2 minutes and crank
engine an additional 20 seconds to assure bearing
surfaces are adequately lubricated.
2. Remove the batteries from storage. Install batteries
(fully charged) and connect the terminals.
3. Install fan/alternator poly-vee belt if removed.
4. Fill fuel tank.
5. Perform all appropriate prestarting checks. ( See
DAILY PRESTARTING CHECKS in Lubrication and
Maintenance/Daily Section.)
7. Start engine and run at low idle and no load for
several minutes. Warm up carefully and check all
gauges before placing engine under load.
8. On the first day of operation after storage, check
overall engine for leaks and check all gauges for
correct operation.

Torque values listed are for general use only, based on the strength of the
bolt or screw. DO NOT use these values if a different torque value or
tightening procedure is given for a specific application. For plastic insert or
crimped steel type lock nuts, for stainless steel fasteners, or for nuts on
U-bolts, see the tightening instructions for the specific application. Shear
bolts are designed to fail under predetermined loads. Always replace shear
bolts with identical grade.
Replace fasteners with the same or higher grade. If higher
grade fasteners are used, tighten these to the strength of the
original. Make sure fastener threads are clean and that you
properly start thread engagement. When possible, lubricate
plain or zinc plated fasteners other than lock nuts, wheel bolts
or wheel nuts, unless different instructions are given for the
specific application.

Emission System Warranty
U.S. EPA Emissions Control Warranty Statement
Emissions control-related parts and components are
warranted by John Deere for five years or 3000 hours
of operation, whichever occurs first. John Deere further
warrants that the engine covered by this warranty was
designed, built, and equipped so as to conform at the
time of sale with all U.S. emissions standards at the
time of manufacture, and that it is free of defects in
materials and workmanship which would cause it not
to meet these standards within the period of five years
or 3000 hours of operation, whichever occurs first.
Warranties stated in this manual refer only to
emissions-related parts and components of your
engine. The complete engine warranty, less
emissions-related parts and components, is provided
separately as the “John Deere New Off-Highway
Engine Warranty”.

Emissions Control System Certification Label
Emissions Label
CAUTION: Statutes providing severe
penalties for tampering with emissions
controls may apply to the user or dealer.
The emissions warranty described below applies only
to those engines marketed by John Deere that have
been certified by the United States Environmental
Protection Agency (EPA) and/or California Air
Resources Board (CARB); and used in the United
States and Canada in non-road mobile (self-propelled
or portable/transportable1) equipment. The presence of
an emissions label like the one shown signifies that the
engine has been certified with the EPA and/or CARB.
The EPA and CARB warranties only apply to new
1
engines having the certification label affixed to the
engine and sold as stated above in the geographic
areas. The presence of an EU number in the third line
of the label signifies that the engine has been certified
with the European Union countries per Directive
97/68/EC. The emissions warranty does not apply to
the EU countries.
NOTE: The hp/kW rating on the engine emissions
certification label specifies the gross engine
hp/kW, which is flywheel power without fan. In
most applications this will not be the same
rating as the advertised vehicle hp/kW rating.
Equipment moved at least once every 12 months.
