Diesel Fuel

Consult your local fuel distributor for properties of thediesel fuel available in your area.

In general, diesel fuels are blended to satisfy the lowtemperature requirements of the geographical area inwhich they are marketed.

Diesel fuels specified to EN 590 or ASTM D975 arerecommended.

Required fuel properties

In all cases, the fuel must meet the followingproperties:

Cetane number of 45 minimum. Cetane numbergreater than 50 is preferred, especially fortemperatures below -20 C (-4 F) or elevations above1500 m (5000 ft).

Cold Filter Plugging Point (CFPP) below theexpected low temperature OR Cloud Point at least5 C (9 F) below the expected low temperature.

Fuel lubricity should pass a minimum load level of3100 grams as measured by ASTM D6078 or,maximum scar diameter of 0.45 mm as measured byASTM D6079.

Sulfur content:

Diesel fuel quality and fuel sulfur content mustcomply with all existing regulations for the area inwhich the engine operates.

Sulfur content less than 0.05% (500 ppm) ispreferred.

If diesel fuel with sulfur content greater than 0.05%(500 ppm) is used, crankcse oil service intervalsmay be affected. (See recommendation for DieselEngine Oil.)

DO NOT use diesel fuel with sulfur content greaterthan 1.0%.

IMPORTANT: DO NOT mix used engine oil or anyother type of lubricating oil withdiesel fuel.

RG41183,0000046 1918DEC011/1

Bio-Diesel Fuel

Consult your local fuel distributor for properties of thebio-diesel fuel available in your area.

Bio-diesel fuels may be used ONLY if the bio-dieselfuel properties meet the latest edition of ASTM PS121,DIN 51606 or equivalent specification.

It has been found that bio-diesel fuels may improvelubricity in concentrations up to a 5% blend inpetroleum diesel fuel.

When using a blend of bio-diesel fuel, the engine oillevel must be checked daily when the air temperatureis -10 C (14 F) or lower. If the oil becomes diluted withfuel, shorten oil change intervals accordingly.

IMPORTANT: Raw pressed vegetable oils are NOTacceptable for use for fuel in anyconcentration in John Deereengines.

These oils do not burn completely,and will cause engine failure byleaving deposits on injectors and inthe combustion chamber.

A major environmental benefit of bio-diesel fuel is itsability to biodegrade. This makes proper storage andhandling of bio-diesel fuel especially important. Areasof concern include:

Quality of new fuel Water content of the fuel Problems due to aging of the fuel

Potential problems resulting from deficiencies in theabove areas when using bio-diesel fuel inconcentrations above 5% may lead to the followingsymptoms:

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

DX,FUEL6 1906DEC001/1

Dieselscan Fuel Analysis

DIESELSCAN is a John Deere fuel sampling program tohelp you monitor the quality of your fuel source. It verifiesfuel type, cleanliness, water content, suitability for coldweather operation, and if fuel is within ASTMspecifications. Check with your John Deere dealer foravailability of DIESELSCAN kits.

OUOD002,0000179 1918DEC011/1

Lubricity of Diesel Fuel

Diesel fuel must have adequate lubricity to ensureproper operation and durability of fuel injection systemcomponents.

Diesel fuels for highway use in the United States andCanada require sulfur content less than 0.05% (500ppm).

Diesel fuel in the European Union requires sulfurcontent less than 0.05% (500 ppm).

Experience shows that some low sulfur diesel fuelsmay have inadequate lubricity and their use mayreduce performance in fuel injection systems due toinadequate lubrication of injection pump components.The lower concentration of aromatic compounds inthese fuels also adversely affects injection pump sealsand may result in leaks.

Use of low lubricity diesel fuels may also causeaccelerated wear, injection nozzle erosion or corrosion,engine speed instability, hard starting, low power, andengine smoke.

Fuel lubricity should pass a minimum load level of3100 gram as measured by the ASTM D6078 ormaximum scar diameter of 0.45 mm as measured byASTM D6079.

ASTM D975 and EN 590 specifications do not requirefuels to pass a fuel lubricity test.

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

Stanadyne DE10 pumps are static lock-pin timedduring installation of the injection pump.

The fuel supply pump is a separate componentmounted on upper right-hand side of engine block andis actuated by a pin in block that rides on enginecamshaft lobe.

Engines may be equipped with an optional fuelpre-filter/water bowl.

All engines are equipped with a round final fuel filterwith water bowl. Hand primer on top of filter element isoptional.

All engines use Stanadyne Rate Shaping Nozzles(RSN).

Field-installed options include fuel heater, water bowland hand fuel primer.

High Pressure Fluids

CAUTION: Escaping diesel fuel under pressurecan have sufficient force to penetrate the skin,causing serious injury. Before disconnectinglines, be sure to relieve pressure. Beforeapplying pressure to the system, be sure ALLconnections are tight and lines, pipes andhoses are not damaged. Keep hands and bodyaway from pinholes and nozzles which ejectfluid under pressure. Use a piece of cardboardor wood, rather than hands, to search forsuspected leaks.

If ANY fluid is injected into the skin, it must besurgically removed within a few hours by adoctor familiar with this type injury or gangrenemay result. Doctors unfamiliar with this type ofinjury may call the Deere & Company MedicalDepartment in Moline, Illinois, or otherknowledgeable medical source.

Any time the fuel system has been opened up for service(lines disconnected or filters removed), it will be necessaryto bleed air from the system. See BLEED THE FUELSYSTEM in this group.

Fuel Injection Nozzle Test

1Nozzle Tester2Pressure Line

CAUTION: The nozzle tip should always bedirected away from the operator. Fuel from thespray orifices can penetrate clothing and skincausing serious personal injury. Enclosing thenozzle in a clear glass beaker is recommended.

Before applying pressure to the nozzle tester,be sure that all connections are tight, and thatthe fittings are not damaged. Fluid escapingfrom a very small hole can be almost invisible.To search for suspected leaks, use a piece ofcardboard or wood, rather than hands.

If ANY fluid is injected into the skin, it must besurgically removed within a few hours by adoctor familiar with this type injury or gangrenemay result.

NOTE: Testing the performance of a nozzle while theengine is running is just a rough test. To obtain atrue check of nozzle performance, use a nozzletester JT25510 (1) and pressure line KJD10109(2).Use only carefully filtered diesel fuel for testingthe injection nozzles, since dirty fuel will severelydamage the precision parts of a nozzle.

Connect the nozzle to the tester so that the axis of thenozzle forms an angle of approximately 30 to the verticaland the spray of fuel is directed downwards. Check allconnections for leaks. Close the gauge shut-off valve andflush (bleed) the nozzle by operating test pump rapidly.

OUO1089,0000200 1907NOV012/3

Spray Pattern Test

Close gauge shut-off valve and operate the pump lever at60 strokes per minute. If the fuel injection nozzle isworking properly, the fuel should issue through all nozzleorifices in a fine, evenly shaped spray cone. This spraycone is inclined from the centerline of the nozzle body, butshould be distributed. For a better check, place a piece ofpaper or cardboard at a suitable distance below thenozzle and check the appearance of the damp circularspots made by the fuel. Deviations from the regular spraypattern or angle may be due to the complete or partialclogging of a nozzle orifice. In this case the fuel issues ina jet rather than in a fine spray.

Checking Valve Stem and Guide Wear

Connect fuel injection nozzle to the nozzle tester with thetip raised a little higher than its opposite end.Cover the tip and pump the tester to a pressure of10 300 kPa (103 bar) (1500 psi). Keep the pressureconstant and observe how much fuel leaks out of thenozzle return end. After the first drop has formed, countthe drops for 30 seconds and compare with specification.

Fuel Injection NozzleSpecificationNozzleReturn Leakage at10 300 kPa (103 bar) (1500 psi) 1 to 14 drops (maximum) within

30 seconds.............

Checking Valve Seat

Connect the nozzle to tester in horizontal position.Operate the pump lever rapidly to bleed the nozzle andallow the valve to seat. Dry the tip of the nozzlethoroughly. Now operate the pump lever slowly until theindicated pressure is approximately 2800 to 3500 kPa(28 to 35 bar) (400 to 500 psi) below opening pressure(see specification for opening pressure). Keep watchingthe nozzle. Under these conditions the fluid should notdrip out of the nozzle tip. However some weeping or lightmoisture on the tip is considered acceptable. Work thepump lever quickly several times in succession to makethe nozzle spray in the normal way. After the last stroke ofthe pump, observe again. If the nozzle is not quiteleakproof, disassemble for servicing.

CAUTION: Escaping fluid under pressure canpenetrate the skin causing serious injury. Avoidhazards by relieving pressure beforedisconnecting hydraulic or other lines. Tightenall connections before applying pressure.Search for leaks with a piece of cardboard.Protect hands and body from high pressurefluids.

If an accident occurs, see a doctor immediately.Any fluid injected into the skin must besurgically removed within a few hours organgrene may result. Doctors unfamiliar withthis type of injury may call the Deere &Company Medical Department in Moline, Illinois,or other knowledgeable medical source.

Any time the fuel system has been opened up for service(lines disconnected or filters removed), it will be necessaryto bleed air from the system.

The fuel system may be bled at one of several locations.On some engine applications it may be necessary toconsult your operators manual and choose the bestlocation for your engine/machine application.

Connectors

Connectors are devices that provide for assembly anddisassembly of systems. Connectors should always beserviced using tools designed for that type of connector. Agood crimp is important to mechanical and electricalsoundness. Repaired connectors should be physicallytested by pulling to be sure the contact is firmly attachedto the conductor.

IMPORTANT: If for some reason the connectors arenot connected, such as when the fuelinjection pump is removed, it isimportant to protect the connectorsfrom debris.

Refer to the procedures which follow for repair of varioustypes of connectors.

RG,RG34710,1335 1923OCT971/1

Use Electrical Insulating Compound

Apply AT66865 Compound directly to the terminalsbetween the wire seal and connector body. This providesa moisture barrier, especially in wet and humid conditions.
