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.
RIGHT-HAND AND LEFT-HAND sides are determined
by standing at the drive or flywheel end (rear) of the
engine and facing toward the front of the engine.
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.
NOTE: This operators manual covers only engines
provided to OEM (Outside Equipment
Manufacturers). For engines in Deere
machines, refer to the machine operators
manual.

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.
RG10603A –UN–15JUN00
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

Handle Chemical Products Safely
Direct exposure to hazardous chemicals can cause
serious injury. Potentially hazardous chemicals used with
John Deere equipment include such items as lubricants,
coolants, paints, and adhesives.
A Material Safety Data Sheet (MSDS) provides specific
details on chemical products: physical and health hazards,
safety procedures, and emergency response techniques.
Check the MSDS before you start any job using a
hazardous chemical. That way you will know exactly what
the risks are and how to do the job safely. Then follow
procedures and recommended equipment.
(See your John Deere dealer for MSDS’s on chemical
products used with John Deere equipment.)

Consult your local fuel distributor for properties of the
diesel fuel available in your area.
In general, diesel fuels are blended to satisfy the low
temperature requirements of the geographical area in
which they are marketed.
Diesel fuels specified to EN 590 or ASTM D975 are
recommended.
Required fuel properties
In all cases, the fuel shall meet the following
properties:
Cetane number of 45 minimum. Cetane number
greater than 50 is preferred, especially for
temperatures below -20°C (-4°F) or elevations above
1500 m (5000 ft).
Cold Filter Plugging Point (CFPP) below the
expected low temperature OR Cloud Point at least
5°C(9°F) below the expected low temperature.
Fuel lubricity should pass a minimum level of 3100
grams as measured by ASTM D6078 or maximum
scar diameter of 0.45 mm as measured by ASTM
D6079 or ISO 12156-1.
Sulfur content:
• Diesel fuel quality and fuel sulfur content must
comply with all existing emissions regulations for the
area in which the engine operates.
• Use of diesel fuel with sulfur content less than
0.10% (1000 ppm) is STRONGLY recommended.
• Use of diesel fuel with sulfur content 0.10% (1000
ppm to 0.50% (5000 ppm) may result in REDUCED
oil and filter change intervals.
• BEFORE using diesel fuel with sulfur content greater
than 0.50% (5000 ppm), contact your John Deere
dealer.
• DO NOT use diesel fuel with sulfur content greater
than 1.0%.
IMPORTANT: Do not mix used diesel engine oil or
any other type of lubricating oil with
diesel fuel.
IMPORTANT: Improper fuel additive usage may
cause damage on fuel injection
equipment of diesel engines.
Lubricity of Diesel Fuel
Most diesel fuels manufactured in the United States,
Canada, and the European Union have adequate
lubricity to ensure proper operation and durability of
fuel injection system components. However, diesel
fuels manufactured in some areas of the world may
lack the necessary lubricity.
IMPORTANT: Make sure the diesel fuel used in
your machine demonstrates good
lubricity characteristics.

CAUTION: Handle fuel carefully. Do not fill
the fuel tank when engine is running.
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.
Keep all storage tanks as full as practicable to
minimize condensation.
Ensure that all fuel tank caps and covers are installed
properly to prevent moisture from entering.
Monitor water content of the fuel regularly.
When using bio-diesel fuel, the fuel filter may require
more frequent replacement due to premature plugging.
Check engine oil level daily prior to starting engine. A
rising oil level may indicate fuel dilution of the engine
oil.
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.
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.

Bio-Diesel Fuel
Fuels, Lubricants, and Coolant
Consult your local fuel distributor for properties of the
bio-diesel fuel available in your area.
Bio-diesel fuels may be used ONLY if the bio-diesel
fuel properties meet the latest edition of ASTM D6751,
EN 14214, or equivalent specification.
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.
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.
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

leaving deposits on injectors and in
the combustion chamber.
A major environmental benefit of bio-diesel fuel is its
ability to biodegrade. This makes proper storage and
handling of bio-diesel fuel especially important. Areas
of concern include:
• Quality of new fuel
• Water content of the fuel
• Problems due to aging of the fuel
Potential problems resulting from deficiencies in the
above areas when using bio-diesel fuel in
concentrations above 5% may lead to the following
symptoms:
• 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

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.
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.
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.
Starting Fluid
A starting fluid port on the intake is available to aid
cold weather starting.
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.

Additional Information About Diesel Engine Coolants and Supplemental Coolant
Additives
Engine coolants are a combination of three chemical
components: ethylene glycol or propylene glycol
antifreeze, inhibiting coolant additives, and quality
water.
Coolant specifications
Some products, including John Deere COOL-GARD
Prediluted Coolant, are fully formulated coolants that
contain all three components in their correct
concentrations. Do not add an initial charge of
supplemental coolant additives to these fully
formulated products.
Coolants meeting ASTM D6210 do not require an
initial charge of supplemental coolant additives.
Some coolant concentrates, including John Deere
COOL-GARD Coolant Concentrate, contain both glycol
antifreeze and inhibiting coolant additives. Mix these
products with quality water, but do not add an initial
charge of supplemental coolant additives.
Coolants meeting ASTM D4985 require an initial
charge of supplemental coolant additives.
Replenish coolant additives
simple mixture of ethylene glycol or propylene glycol
and water will not give adequate protection.
Use of supplemental coolant additives reduces
corrosion, erosion, and pitting. These chemicals
reduce the number of vapor bubbles in the coolant and
help form a protective film on cylinder liner surfaces.
This film acts as a barrier against the harmful effects
of collapsing vapor bubbles.
Avoid automotive-type coolants
Never use automotive-type coolants (such as those
meeting ASTM D3306). These coolants do not contain
the correct additives to protect heavy-duty diesel
engines. They often contain a high concentration of
silicates and may damage the engine or cooling
system.
Water quality
Water quality is important to the performance of the
cooling system. Distilled, deionized, or demineralized
water is recommended for mixing with ethylene glycol
and propylene glycol base engine coolant concentrate.
All water used in the cooling system should meet the
following minimum specifications for quality:
The concentration of coolant additives is gradually
depleted during engine operation. Periodic
replenishment of inhibitors is required, even when
John Deere COOL-GARD or another fully formulated
coolant is used. Follow the recommendations in this
manual for the use of supplemental coolant additives.
Why use supplemental coolant additives?
Operating without proper coolant additives will result in
increased corrosion, cylinder liner erosion and pitting,
and other damage to the engine and cooling system. A

Freeze protection
The relative concentrations of glycol and water in the
engine coolant determine its freeze protection limit.
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.
IMPORTANT: Do not add a supplemental coolant
additive when the cooling system is
drained and refilled with John

DO NOT use a coolant-water mixture greater than
60% ethylene glycol or 60% propylene glycol.
DX,COOL7 –19–19DEC03–2/2
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.

gauges provided by John Deere.
IMPORTANT: Any time an electric gauge or meter
does not register correctly, replace it
with a new one. Do not attempt to repair
it.
Following is a brief description of the components on the
instrument (gauge) panel:
A—Oil Pressure Gauge - This gauge indicates oil
pressure. It also has an adjustable electrical contact which
activates the safety switch when oil pressure goes below
the pressure set point. This will automatically stop the
engine.
North American Instrument Panel
RG11299B –UN–17AUG00
B—Coolant Temperature Gauge - This gauge indicates
coolant temperature. It also has an electrical contact
which activates the safety switch when coolant
temperature goes above the temperature set point. This
will automatically stop the engine.
C—Key Switch - The key switch is used to start and stop
the engine. A key is required to operate the switch so as
to prevent unauthorized operation of the engine.
D—Tachometer - The tachometer indicates engine speed
in hundreds of revolutions per minute (rpm).
E—Safety Switch (Reset Button) - The safety switch
de-energizes the fuel shut-off solenoid or injection rack
puller to stop the engine, if one or more conditions are
met:
The reset button has to be held in when starting the
engine. The button allows the safety switch to override the
shut-down circuits until safe engine oil pressure is
maintained. Once engine oil pressure is within
specifications, the safety switch will latch and the reset
button can be released.
F—Fuse Holder - Contains 14 amp fuse.
G—Ammeter - The ammeter indicates the rate of charge
(+) or discharge (—) of the battery. When the engine is
first started, the ammeter will usually indicate a charge
rate of approximately 30 amps. After a short period of
operation, the ammeter needle will point slightly to the
right of “0”, indicating the charging system is operating
normally. A problem with the charging system is indicated
if the ammeter needle points to the left of “0” during
engine operation.
H—Hour Meter - The hour meter operates when the
engine is operating, or when the reset button is manually
held in while the key switch is in the ON position. The
accumulated hours are displayed in hours and tenths of
hours. On some panels, the hourmeter may be separate
from the tachometer.
I—Hand Throttle - The hand throttle is used to manually
control engine speed. If the hand throttle is electronic (as
shown), turn the knob clockwise or counterclockwise to
change engine speed. If the hand throttle is mechanical
(not shown), turning the handle, either clockwise or
counterclockwise, will lock the throttle position. Turn the
handle half way between the two lock positions to unlock
the throttle.
J—Tachometer Binary Code - The tachometer is
calibrated to the number of flywheel gear teeth read. The
dip switch to set the binary code is located in back of
tachometer and must be set at “10110011” to operate at
30 pulses per revolution.

Cold Weather Operation
CAUTION: Ether injector starting fluid is highly
flammable. DO NOT use starting fluid on
engines equipped with air intake heaters.
DO NOT use starting fluid near fire, sparks, or
flames. DO NOT incinerate or puncture a
starting fluid container.
Engine Operating Guidelines
Engines may be equipped with intake air heaters, coolant
heaters, or ether injectors as a cold weather starting aid.
Starting aids are required below 32°F(0°C). They will
enhance starting performance above these temperatures
and may be needed to start applications that have high
parasitic loads during cranking and/or start acceleration to
idle.
Using correct grade of oil (per engine and machine
operator’s manual) is critical to achieving adequate cold
weather cranking speed.
Other cold weather starting aids are required at
temperatures below -22°F (-30°C) or at altitudes above
1500 m (5000 ft).
1. Follow steps 1—4 as listed under , then proceed as
follows according to the instrument (gauge) panel on
your engine.
2. Switch on the air intake heater for 30 seconds or
activate ether injector by following suppliers
instructions.

Engine Operating Guidelines
Changing Engine Speed
To increase engine speed, turn throttle handle (A), if
equipped, to the horizontal position and pull out until
desired engine speed is obtained. Turn the handle in
either direction to lock throttle position. The handle is
pushed inward to decrease engine speed.
NOTE: On engines without handle, use throttle lever to
control engine speed.
A—Throttle Handle
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.
Once an engine is warmed to normal operating
temperatures, engine should be idled at slow idle

factory. If an engine will be idling for more than 5
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).
been operating at working load, idle
engine at least 2 minutes at 1000–1200
rpm to cool hot engine parts.
For engines in generator set
applications, where the governor is
locked at a specified speed and no slow
idle function is available, run engine for
at least 2 minutes at fast idle and no
load.
3. Turn key switch (B) to "OFF" position to stop the
engine. Remove ignition key.

Checking Air Intake System
IMPORTANT: The air intake system must not leak.
Any leak, no matter how small, may
result in internal engine damage due to
abrasive dirt and dust entering the
intake system.
1. Inspect all intake hoses (piping) for cracks. Replace as
necessary.
2. Check clamps (A) on piping which connect the air
cleaner, engine and, if present, turbocharger. Tighten
clamps as necessary. This will help prevent dirt from
entering the air intake system through loose
connections causing internal engine damage.
3. If engine has a rubber dust unloader valve (B), inspect
the valve on bottom of air cleaner for cracks or
plugging. Replace as necessary.
IMPORTANT: ALWAYS REPLACE primary air cleaner
element when air restriction indicator
shows a vacuum of 625 mm (25 in.)
H2O, is torn, or visibly dirty.
4. Test air restriction indicator (C) for proper operation.

Replenishing Supplemental Coolant Additives (SCAs) Between Coolant Changes
Radiator Coolant Check
IMPORTANT: Do not add supplemental coolant
additives when the cooling system is
drained and refilled with John Deere
COOL-GARD
NOTE: If system is to be filled with coolant that does
not contain SCAs, the coolant must be
precharged. Determine the total system
capacity and premix with 3% John Deere
Coolant Conditioner.
Through time and use, the concentration of coolant
additives is gradually depleted during engine operation.
Periodic replenishment of inhibitors is required, even
when John Deere COOL-GARDis used. The cooling
system must be recharged with additional
supplemental coolant additives available in the form of
liquid coolant conditioner.
Maintaining the correct coolant conditioner
concentration (SCAs) and freeze point is essential in
RG6261 –UN–08DEC97
JT07298 Coolant/Battery Tester
your cooling system to protect against rust, liner pitting
and corrosion, and freeze-ups due to incorrect coolant
dilution.
John Deere LIQUID COOLANT CONDITIONER is
recommended as a supplemental coolant additive
in John Deere engines.
DO NOT mix one brand of SCA with a different
brand.
Test the coolant solution every 500 hours or 12
months of operation using either John Deere coolant
test strips or a COOLSCANanalysis. If a
COOLSCANanalysis is not available, recharge the
system per instructions printed on label of John Deere
Liquid Coolant Conditioner.

IMPORTANT: ALWAYS maintain coolant at correct
level and concentration. DO NOT
operate engine without coolant even
for a few minutes.
If frequent coolant makeup is
required, the glycol concentration
should be checked with JTO7298
Coolant/Battery Tester to ensure that
the desired freeze point is
maintained. Follow manufacturer’s
instructions provided with
Coolant/Battery Tester.
Add the manufacturer’s recommended concentration of
supplemental coolant additive. DO NOT add more than
the recommended amount.
The use of non-recommended supplemental coolant
additives may result in additive drop-out and gelation
of the coolant.
If other coolants are used, consult the coolant supplier
and follow the manufacturer’s recommendation for use
of supplemental coolant additives.
See DIESEL ENGINE COOLANTS AND
SUPPLEMENTAL ADDITIVE INFORMATION for
proper mixing of coolant ingredients before adding to
the cooling system.
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
DPSG,OUOD002,1921 –19–07JAN02–2/2
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.
