FORD F750 2001 10.G Owners Manual

²8±hole disc
Always tighten wheel lug nuts
alternately in the sequence shown.
Make sure the wheel is drawn
evenly against the hub or drum.
Check for damage that would affect
the runout of the wheels. Wobble or
shimmy caused by a damaged wheel
will eventually damage the wheel
bearings. Stones or lumps of mud
wedged between a wheel and drum
or between dual wheels can unbalance a wheel and tire.
Servicing your tires
Inspect the tire treads and remove stones, nails, glass or other objects
that may be wedged in the tread grooves. Check for holes or cuts that
may permit air leakage from the tire and make the necessary repairs.
Inspect the tire sidewalls for cuts, bruises and other damage. If internal
damage to the tire is suspected, have the tire removed from wheel and
inspected.
Check the pressure regularly. Maintain the recommended air pressure for
your vehicle, load, tires and rims or wheels. Check the tire valve for air
leaks and replace the valve if necessary. If the valve cap is missing,
install a new cap.
An inflated tire and rim can be very dangerous if improperly
used, serviced or maintained. To avoid serious injury, never
attempt to re-inflate a tire which has been run flat or seriously
under-inflated without first removing the tire from the wheel assembly
for inspection. Do not attempt to add air to tires or replace tires or
wheels without first taking precautions to protect persons and
property.
Refer to the Ford Service Manual or the regulations of the Occupational
Safety and Health Administration (OSHA) for appropriate procedures
and cautions.

Tire inflation pressure must not exceed the recommendations of
the axle, tire and/or wheel rim manufacturer for the specific
load, speed and application. The inflation pressures on the tire sidewall
do not take the wheel rim capabilities into consideration.
Never use a rim of different manufacture or any different size or
type than original rims.
Try to replace tires in pairs on the same axle shaft. Tires larger or
smaller than originally installed may affect the accuracy of the
speedometer. Consult your dealer about the need to change the switch
setting on the back of the speedometer.
Front wheel alignment
If abnormal tire wear or ride and handling characteristics such as vehicle
lead or wander are experienced with properly inflated tires, the front
end alignment should be checked.
Wheel bearing care
Front and rear wheel bearings are adjustable to correct for bearing and
spindle wear. Long bearing life depends upon proper adjustment and
correct lubrication. If bearings are adjusted too tightly (preloaded) they
will overheat and wear rapidly. Loose adjustment will cause pounding
and will contribute to uneven tire wear, steering difficulties and
inefficient brake operation.
Refer to the Ford Service Manual applicable to your vehicle for proper
tightening procedures and torque specifications.
Periodically check the oil level on oil filled front bearing hubs. If
necessary, add oil through the filler plug so the oil level is between the
ADD and FULL marks indicated on the hub. Do not overfill. Overfilling
can result in oil on brake linings.
Refer to your Scheduled Maintenance Guide for fluid level checks and
change intervals for the front hubs.
Your front hubs may be filled with an optional synthetic fluid which
allows use of the extended service intervals. A green colored filler plug
identifies use of the synthetic fluid.

FUEL INFORMATION
Important safety precautions
Do not overfill the fuel tank. The pressure in an overfilled tank
may cause leakage and lead to fuel spray and fire.
The fuel system may be under pressure. If the fuel cap is venting
vapor or if you hear a hissing sound, wait until it stops before
completely removing the cap.
Automotive fuels can cause serious injury or death if misused or
mishandled.
Maintenance and care
183

Observe the following guidelines when handling fuel:
²Extinguish all smoking materials
and any open flames before
fueling your vehicle.
²Always turn off the vehicle before
fueling.
²Automotive fuels can be harmful
or fatal if swallowed. If fuel is
swallowed, call a physician
immediately, even if no symptoms
are immediately apparent. The
toxic effects of fuel may not be visible for hours.
²Avoid inhaling fuel vapors. Inhaling too much fuel vapor of any kind
can lead to eye and respiratory tract irritation. In severe cases,
excessive or prolonged breathing of fuel vapor can cause serious
illness and permanent injury.
²Avoid getting fuel liquid in your eyes. If fuel is splashed in the eyes,
remove contact lenses (if worn), flush with water for 15 minutes and
seek medical attention. Failure to seek proper medical attention could
lead to permanent injury.
²Fuels can also be harmful if absorbed through the skin. If fuel is
splashed on the skin and/or clothing, promptly remove contaminated
clothing and wash skin thoroughly with soap and water. Repeated or
prolonged skin contact with fuel liquid or vapor causes skin irritation.
If you must replace the fuel filler cap, replace it with a genuine
Ford or Motorcraft part. The customer warranty may be void for
any damage to the fuel tank or fuel system if a genuine Ford or
Motorcraft fuel filler cap is not used.
If you do not use the proper fuel filler cap, excessive pressure or
vacuum in the fuel tank may damage the fuel system or cause
the fuel system to work improperly in a collision, which may result in
possible personal injury.
Maintenance and care
184

Choosing the right fuel
At operating temperatures below 0ÉC (32ÉF), use a blend of No. 1D and
No. 2D Diesel fuels, also known as winterized No. 2D.
Do not use diesel fuel blended with waste oil in engines equipped with a
catalytic converter-muffler. Blending waste oil in with the fuel will plug
the catalytic converter-muffler, resulting in a significant loss of engine
power. Your emissions warranty will be voided if blending waste oil with
diesel fuel is practiced.
Use low sulfur (less than 0.05% by weight) fuel as required by the EPA
for emission compliance.
Do not mix diesel fuel with gasoline, gasohol or alcohol. This
could cause an explosion resulting in personal injury.
Do not use starting fluid such as ether or gasoline. Such fluids
can cause immediate explosive damage to the engine and
possible personal injury.
Running out of fuel
Avoid running out of fuel as this will allow air to enter the fuel system,
which will make restarting the vehicle difficult.
If you have run out of fuel:
²If your vehicle is equipped with dual fuel tanks,add at least
15±19 liters (4±5 gallons) of fuel to each tank before attempting to
restart the engine.
²If your vehicle is equipped with the Caterpillar 3126 B engine,
the fuel system must be primed before attempting to restart the
engine. Refer to the engine operator's manual for instructions on
priming the engine.
²Use caution not to overheat and damage the starterby cranking
the engine for an excessive period of time. You may need to crank the
engine for a longer time than normal. If the engine fails to start in 30
seconds, turn the ignition to the OFF position and wait for two
minutes before cranking the engine again.
²Any remaining trapped air will self-purge from the fuel system once
the engine starts running.
²
The engine may run rough and produce white smoke while air is in the
fuel system. This is normal and should stop after a short period of time.
Maintenance and care

procedures.
ESSENTIALS OF GOOD FUEL ECONOMY
Measuring techniques
Your best source of information about actual fuel economy is you, the
driver. You must gather information as accurately and consistently as
possible. Fuel expense, frequency of fillups or fuel gauge readings are NOT
accurate as a measure of fuel economy. We do not recommend taking fuel
economy measurements during the first 1 600 km (1 000 miles) of driving
(engine break-in period). You will get a more accurate measurement after
3 000 km±5 000 km (2 000 miles-3 000 miles).
The advertised fuel capacity of the fuel tank(s) on your vehicle is equal
to the rated refill capacity of the fuel tank(s) as listed inFuel Tank
Capacitiesin theCapacities and Specificationschapter. The
advertised capacity is the amount of the Indicated Capacity and the
Empty Reserve combined. Indicated Capacity is the difference in the
amount of fuel in a full tank and a tank when the fuel gauge indicates
empty. Empty Reserve is the small amount of usable fuel remaining in
the fuel tank after the fuel gauge indicates empty.
Maintenance and care
189

The amount of Empty Reserve varies and should not be relied
upon to increase driving range. When refueling your vehicle after
the fuel gauge indicates empty, you might not be able to refuel
the full amount of the advertised capacity of the fuel tank due to
the empty reserve still present in the tank.
Filling the tank
For consistent results:
²Use the same fill rate setting (low Ð medium Ð high) each time
during filling.
²Allow three automatic click-offs when filling.
²Always use fuel of a known quality, preferably a national brand.
²Have the vehicle loading and distribution the same every time.
²When refueling a vehicle equipped with dual fuel tanks, if the two
tanks are not filled equally, the fuel gauge reading may fluctuate
slightly until the fuel level between the two tanks balance out and
become equal.
Your results will be most accurate if your filling method is consistent.
Calculating fuel economy
1. Fill the fuel tank(s) completely and record the initial odometer reading
(in kilometers or miles).
2. Each time you fill the tank(s), record the amount of fuel added (in
liters or gallons).
3. After at least three to five tank fill-ups, fill the fuel tank(s) and record
the current odometer reading.
4. Subtract your initial odometer reading from the current odometer reading.
5. Follow one of the simple calculations in order to determine fuel economy:
Multiply liters used by 100, then divide by total kilometers traveled.
Divide total miles traveled by total gallons used.
