Service Miscellaneous

Using Proper Fuel (Diesel)

Use the proper diesel fuel to help prevent decreased engine performance and increased exhaust emissions. Failure to follow the fuel requirements listed below can void your engine warranty.

Consult your local fuel distributor for properties of the diesel fuel 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 when temperatures are below -20?C (-4?F) or elevations above 1500 m (5000 ft).

Cold Filter Plugging Point (CFPP) should be at least 5?C (9?F) below the expected lowest temperature or Cloud Point below the lowest ambient temperature.

Fuel lubricity should pass a maximum scar diameter of 0.45 mm as measured by ASTM D6079 or ISO 12156-1.


IMPORTANT: Avoid damage! Improper fuel additive usage may cause damage on fuel injection equipment of diesel engines.

If a fuel of low or unknown lubricity is used, addition of John Deere PREMIUM DIESEL FUEL CONDITIONER at the specified concentration is recommended.

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 only ultra low sulfur diesel (ULSD) fuel with a maximum of 0.0015% (15mg/kg) sulfur content.


IMPORTANT: Avoid damage! Do not mix diesel engine oil or any other type of lubricating oil with diesel fuel.

Using Bio-Diesel Fuel

Bio-diesel fuels may be used only if the bio-diesel fuel properties meet the latest edition of ASTM D6751, ASTM D7467, EN14214, or equivalent specification.

The current maximum allowable bio-diesel concentration is a 5% blend (also known as B5) in petroleum diesel fuel.

Concentrations up to B20 may be used if machine is modified with genuine John Deere B20 kit. Use of B6-B20 fuel will require maintenance interval changes from some components, and special procedures for fuel handling and machine storage.

To learn of any changes to the recommendations for bio-diesel usage with your diesel engine, ask your John Deere dealer or reference the Services and Support link on the John Deere Commercial and Consumer Equipment website.

Handling and Storing Diesel Fuel

c CAUTION: Avoid injury! 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.


IMPORTANT: Avoid damage! Do not use galvanized containers—diesel fuel stored in galvanized containers reacts with zinc coating in the container to form zinc flakes. If fuel contains water, a zinc gel will also form. The gel and flakes will quickly plug fuel filters and damage fuel injectors and fuel pumps.

• Fill the fuel tank at the end of each day’s operation to prevent water condensation and freezing during cold weather.

• 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 to prevent water condensation. Contact your fuel supplier for recommendations.

Filling Fuel Tank

c CAUTION: Avoid injury! Fuel vapors are explosive and flammable:

• Shut engine off before filling fuel tank.

• Allow engine to cool before refueling.

• Do not smoke while handling fuel.

• Keep fuel away from flames or sparks.

• Fill fuel tank outdoors or in well ventilated area.

• Clean up spilled fuel immediately.

• Use clean approved non-metal container to prevent static electric discharge.


IMPORTANT: Avoid damage! Dirt and water in fuel can cause engine damage: • Clean dirt and debris from the fuel tank opening. • Use clean, fresh, stabilized fuel. • Fill the fuel tank at the end of each day’s operation to keep condensation out of the fuel tank. • Use a non-metallic funnel with a plastic mesh strainer when filling the fuel tank or container.

Fill fuel tank at the end of each day’s operation to prevent condensation and freezing during cold weather.

1. Park machine safely. (See Parking Safely in the SAFETY section.)

2. Allow engine to cool.

3. Remove any trash from area around fuel tank cap.

4. Remove fuel tank cap slowly to allow any pressure built up in tank to escape.

5. Fill fuel tank only to bottom of filler neck. Do not overfill.

6. Install fuel tank cap.

• Gas models: Turn cap until clicks.

Removing and Installing Drive Wheels

Removing:

c CAUTION: Avoid injury! The machine can fall or slip from an unsafe lifting device or supports.

• Use a safe lifting device rated for the load to be lifted.

• Lower machine onto jack stands or other stable supports and block wheels before servicing.


IMPORTANT: Avoid damage! Lift machine at specified points on frame. Using rear bumper as a lift point can damage the frame.

1. Park machine safely. (See Parking Safely in the SAFETY section.)

2. Remove hood.

3. Slightly loosen four wheel nuts.

DM2129

4. Lift rear end of machine with a safe lifting device centered under tire support frame (A) on the side the tire is being removed.

5. Place machine on jack stands.

6. Remove wheel nuts.

7. Remove wheel.

Installing:

1. Install new wheel.

2. Install wheel nuts.

3. Tighten wheel nuts.

4. Lower machine.

Tightening Drive Wheel Hardware

1. Tighten rear wheel nuts to 115 N•m (85 lb-ft)

MX10287

2. Tighten wheel nuts in numbered sequence shown. Tighten alternately until recommended torque value is reached.

Removing and Installing Front Caster Wheels

Removing

1. Park machine safely. (Refer to Parking Safely in the Safety section.)

2. Lift front of machine with a safe lifting device.

MX15745

3. Remove hex nut (A) and wheel bolt (C).

4. Remove wheel and cups from assembly yoke (B).

Installing

1. Install replacement wheel with cups (D).

2. Install wheel bolt (C) and hex nut (A).

3. Tighten nut.

4. Lower machine.

Checking Tire Pressure

c CAUTION: Avoid injury! Explosive separation of tire and rim parts is possible when they are serviced incorrectly:

• Do not attempt to mount a tire without the proper equipment and experience to perform the job.

• Do not inflate the tires above the recommended pressure.

• Do not weld or heat a wheel and tire assembly. Heat can cause an increase in air pressure resulting in an explosion. Welding can structurally weaken or deform the wheel.

• Do not stand in front or over the tire assembly when inflating. Use a clip-on chuck and extension hose long enough to allow you to stand to one side.

1. Check tires for damage.

NOTE: Refer to the SPECIFICATIONS section for tire pressures.

2. Check tire pressure with an accurate lower pressure gauge.

3. Add or remove air, if necessary.

Tightening ROPS Hardware

1. Park machine safely. (See Parking Safely in the SAFETY section.

2. Raise ROPS to upright position and insert lock pins.

3. Tighten the ROPS attaching bolts (A) to 90 Nm (66 lb-ft).

Cleaning Plastic Surfaces


IMPORTANT: Avoid damage! Improper care of machine plastic surfaces can damage that surface: • Do not wipe plastic surfaces when they are dry. Dry wiping will result in minor surface scratches. • Use a soft, clean cloth (bath towel, diaper, automotive mitt). • Do not use abrasive materials, such as polishing compounds, on plastic surfaces.

1. Wash surface with clean water and a mild liquid automotive washing soap.

2. Dry thoroughly to avoid water spots.

IMPORTANT: Avoid damage! Do not use rubbing compound on painted surfaces.

2. Use automotive polishing compound to remove surface scratches.

3. Apply wax to entire surface.

Repairing Deep Scratches (bare metal or primer showing):

1. Clean area to be repaired with rubbing alcohol or mineral spirits.

2. Use paint stick with factory-matched colors available from your authorized dealer to fill scratches. Follow directions included on paint stick for use and for drying.

3. Smooth out surface using an automotive polishing compound. Do not use power buffer.

4. Apply wax to surface.
