Engine Serial Number Plate

Each engine has a 13-digit John Deere engine serial number. The first two digits identify the factory that produced the engine:

• “CD” = Saran, France

• “PE” = Torreon, Mexico

• “T0” = Dubuque, Iowa

• “J0” = Rosario, Argentina

The engine’s serial number plate (A) is located on the right-hand side of cylinder block behind the fuel filter.

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.

RG11946 –UN–06NOV01

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.

Diesel Fuel

Fuels, Lubricants, and Coolant

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.

DX,FUEL1 –19–17NOV05–1/1

Fuel lubricity should pass a minimum load level of 3100 grams as measured by ASTM D6078 or a maximum scar diameter of 0.45 mm as measured by ASTM D6079 or ISO 12156-1.

If fuel of low or unknown lubricity is used, add John Deere PREMIUM DIESEL FUEL CONDITIONER (or equivalent) at the specified concentration.

Handling and Storing Diesel Fuel

Fuels, Lubricants, and Coolant

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 concentration in John Deere engines.

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.

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.

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.

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:

• 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.

Oil types (premium or standard) in the tables include:

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.

2. Locate your engine oil pan option code (19__) on engine label.

3. In the chart column under your oil pan code, select whether you use premium oil (PLUS-50 or equivalent) or standard grade oil.

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).

• “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.

Engine Preheater Indicator (Optional)

The engine preheater indicator (K) lights up while the engine is being preheated for cold weather starting. When the engine is warmed up, the light goes off, indicating the engine can now be started.

Key Start Switch

The three-position key start switch (L) controls the engine electrical system. When the key switch is turned clockwise to “START”, the engine will crank. When the engine starts, the key is released and returns to the “ON” (RUN) position.

Override Shutdown Rocker Switch

Switch will be present, but may not be active, depending on engine controller (ECU) options originally selected. If switch is active, pressing the upper half of the override shutdown switch (M) will override an engine shutdown signal. The switch must be pressed within 30 seconds to prevent undesired shutdown of engine. Pressing this switch will override the engine shutdown for 30 seconds at a time to move vehicle to a safe location.

High-Low Speed Select Rocker Switch

This instrument panel has two versions, one with a two position switch as shown, and one with a three position switch. The two position switch has high/low and 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 (O) with speed select switch (P).

The three position switch has Slow (turtle), Middle (Adj) and Fast (rabbit) settings. Slow (turtle) position is factory preset at low engine idle, while middle (ADJ) position is factory set at high engine idle. To adjust engine speeds, See Changing Engine Speeds in Section 18.

Bump Speed Enable Rocker Switch

This is a three-position switch (O) with the center position as “OFF” (locked). With this switch in the “OFF” position, the speed select switch (P) is also locked, to prevent accidental changes in operating speed. Pressing upper or lower half of switch (O) will unlock or enable the bump speed switch to take effect using speed select switch (P).

Speed Select Rocker Switch

The speed select switch (P) 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 (O) in the unlocked position (top or bottom half of button depressed).

How To Select Preset Operating Speeds (Bump Speeds)

First select slow or fast speed option by pressing high-low speed select switch (N) to “turtle” (slow) or “rabbit” (fast). Then you can press either the upper or lower portion of the bump speed enable switch (O) to unlock the high or low setting. The bump speed enable must be held down as the speed select switch (P) is used to change the high or low setting by pressing (+) to increase speed or (-) to decrease speed.

Once the slow idle speed has been set, the bump speed enable switch must be pressed and released three

times within two seconds to commit the new operating speed to memory. If not done, the engine’s

new speed will only be effective until the key switch is shut off. Then the speed will revert back to the previous setting.

The fast idle speed cannot be locked into memory. It will always go back to the factory preset fast idle speed.

Fuse Holder

The fuse holder (Q) contains a 5-amp fuse for power to the instrument panel.

Tachometer

The tachometer (R) indicates engine speed in hundreds of revolutions per minute (rpm).

Percent Load (Optional)

The power meter (S) shows percent of available power being used by the engine.

Voltmeter

The voltmeter (T) indicates system battery voltage. The amber “WARNING” light (B) will illuminate when battery voltage is too low for proper operation of the fuel injection system.

Engine Coolant Temperature Gauge

The coolant temperature gauge (U) indicates engine coolant temperature in degrees Celsius or Fahrenheit. An optional audible alarm (G) warns the operator if coolant temperature rises above the preset safe operating temperature.

Cruise Control

Engine ECUs are available with the cruise control function. The cruise control is an off-road type that maintains a constant engine rpm under varying load conditions.

The cruise cancel/resume function is a one-button cancel, then resume, function. The first time contact is made with the cruise control active, the cruise control will disengage and the engine speed will drop to idle. If the contact is made again within one minute and with the engine speed above 1300 rpm, the cruise control will “resume”. This feature allows the placement of the cancel/resume button in a convenient location in the vehicle cab and does not require the use of the normal cruise controls for momentary interruptions in cruise operation.

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.

Instrument Panel (Continued)

A—Diagnostic Gauge/Hour Meter

The diagnostic gauge (A) displays diagnostic trouble codes (DTCs) as they are accessed. Other information on the engine can be accessed using the touch keys (N, O and P). The hour meter feature shows the operating hours of the engine and should be used as a guide for scheduling periodic maintenance. If the diagnostic gauge receives a trouble code from an engine control unit, the current display will switch to a warning or shutdown (depending on the severity of the code) screen that will display the trouble code number, the description of the code and the corrective action needed.

B—Tachometer

The tachometer (B) indicates engine speed in hundreds of revolutions per minute (rpm).

C—Voltmeter (Optional)

The voltmeter (C) indicates system battery voltage. The amber “Warning” light (Q) will illuminate when battery voltage is too low for proper operation of the fuel injection system.

D—Audible Alarm (Optional)

The audible alarm (D) will sound whenever low oil pressure, high coolant temperature, or water-in-fuel conditions exist. This includes all signals that light up the amber “warning” indicator (intermittent alarm) or the red “stop engine” indicator (steady alarm).

E—Audible Alarm Override Button

The optional audible alarm has an override button (E) that silences the audible alarm for approximately two minutes when pressed.

F—Key Start Switch

The three-position key start switch (F) controls the engine electrical system. When the key switch is turned clockwise to “START”, the engine will crank.

When the engine starts, the key is released and returns to the “ON” (RUN) position.

G—Override Shutdown Rocker Switch

Switch will be present, but may not be active, depending on engine controller (ECU) options originally selected. If switch is active, pressing the upper half of the override shutdown switch (G) will override an engine shutdown signal. The switch must be pressed within 30 seconds to prevent undesired shutdown of engine. Pressing this switch will override the engine shutdown for 30 seconds at a time to move vehicle to a safe location.

H—Bump Speed Enable Rocker Switch

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. To adjust engine speeds, See Changing Engine Speeds in Section 18.

How To Select Preset Operating Speeds (Bump Speeds)

First select Turtle (Slow) or Adj by pressing speed select switch (J) to “Turtle” (slow) or “Adj”(center). Then you can press either the upper or lower portion of the bump speed enable switch (H) to unlock the setting. The bump speed enable must be held down as the speed select switch (J) is used to change the setting by pressing (+) to increase speed or (-) to decrease speed.

Once the slow idle speed has been set, the bump speed enable switch must be pressed and released

three times within two seconds to commit the new operating speed to memory. If not done, the engine’s

new speed will only be effective until the key switch is shut off. Then the speed will revert back to the previous setting.

The fast idle speed is not adjustable. It will always go back to the factory preset fast idle speed.

K—Analog Throttle Control (Optional)

warns the operator if coolant temperature rises above the preset safe operating temperature.

N—Menu Key

The menu key is pressed to either enter or exit the menu screens on the diagnostic gauge.

O—Arrow Keys

Use the arrow keys (O) to change the display on the window of the diagnostic gauge and to access engine performance data.

Pressing the left arrow to scroll to the left or upward or the right arrow to scroll to the right or downward. This will allow you to view various engine parameters and any diagnostic trouble codes that occur.

Refer to the following story for accessing engine information on the diagnostic gauge using the touch keys.

P—Enter Key

The throttle control (K) is used to control engine speed. This control is available only on engines with analog throttle.

L—Engine Oil Pressure Gauge

The oil pressure gauge (L) indicates engine oil pressure. An audible alarm (D) warns the operator if engine oil pressure falls below a safe operating pressure.

M—Engine Coolant Temperature Gauge

The engine coolant temperature gauge (M) indicates engine coolant temperature. An audible alarm (D)

The enter key is pressed to select the parameter that is highlighted on the screen.

Q—Amber “WARNING” Indicator Light

When light comes on, an abnormal condition exists. It is not necessary to shutdown engine immediately, but problem should be corrected as soon as possible.

Instrument Panel (Earlier 4.5 L “270” Engines)

All controls and gauges are optional equipment for John Deere 4.5 L suffix “270” OEM Engines. They may be provided by the equipment manufacturer instead of 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 a basic instrument (gauge) panel:

A—Tachometer with Hourmeter - The optional tachometer with hourmeter indicates engine speed in revolutions per minute (rpm) and shows the operating hours of the engine while key switch is in the “ON” position. The hour meter should be used as a guide for scheduling periodic service.

B—Coolant Temperature Gauge - The coolant temperature gauge indicates the engine coolant temperature. It is connected to a warning lamp to warn the operator if coolant temperature rises above the preset, safe operating temperature.

C—Oil Pressure Gauge - The oil pressure gauge indicates engine oil pressure. It is connected to a warning lamp to warn the operator if engine oil pressure falls below a safe operating pressure.

D—Pre-Heat Indicator Lamp - This indicator lamp is initially turned on when the key switch is turned to the “HEAT” position to activate the preheater for cold weather starting. Lamp is connected to a timer that turns the lamp off after 15 seconds when the key switch is held at “HEAT” position. When the lamp goes out, start the engine.

A—Tachometer with Hourmeter B—Coolant Temperature Gauge C—Oil Pressure Gauge D—Pre-Heat Indicator Lamp E—Charge Indicator Lamp F—Oil Pressure Indicator Lamp G—Coolant Temperature Indicator Lamp H—Key Switch

E—Charge Indicator Lamp - Indicates whether the

charging circuit is adequately replacing battery voltage as it is used by the electrical system. If the lamp is lit while the engine is running above 1300 rpm, stop engine immediately and check charging circuit.
