Ford F-650/750 (2018 year). Manual - part 62

WARNINGS

Do not attempt to change a tire on
the side of the vehicle close to
moving traffic. Pull far enough off the

road to avoid the danger of being hit when
operating the jack or changing the wheel.

Note: Passengers should not remain in the
vehicle when the vehicle is being jacked.

Park on a level surface, set the parking
brake and activate the hazard flashers.

1.

Turn the engine off and block the wheel
that is diagonally opposite of the flat
tire using a wheel chock.

2. Loosen each wheel lug nut ½ turn

counterclockwise, but do not remove
them until the wheel is raised off the
ground.

3. Replace the flat tire with the spare tire,

making sure the valve stem is facing
outward on all front and inboard rear
wheels. If you are replacing the
outboard wheel, the valve stem must
be facing inward. Reinstall the lug nuts
until the wheel is snug against the hub.
Do not fully tighten the lug nuts until
the wheel has been lowered.

4. Lower the wheel and fully tighten the

lug nuts in the order shown below.  See
Technical Specifications (page 253).

5. Unblock the wheels.

WARNING

When you install a wheel, always remove any corrosion, dirt or foreign materials
present on the mounting surfaces of the wheel or the surface of the wheel hub,
brake drum or brake disc that contacts the wheel. Make sure to secure any fasteners

that attach the rotor to the hub so they do not interfere with the mounting surfaces of
the wheel. Installing wheels without correct metal-to-metal contact at the wheel mounting
surfaces can cause the wheel nuts to loosen and the wheel to come off while your vehicle
is in motion, resulting in loss of vehicle control, personal injury or death.

Torque specifications are for nut and bolt threads free of dirt and rust. Use only Ford

recommended replacement fasteners.

On vehicles equipped with single rear wheels, retighten the lug nuts to the specified torque
at 100 miles (160 kilometers) after any wheel disturbance (such as tire rotation, changing
a flat tire, wheel removal).

On vehicles equipped with dual rear wheels, retighten the lug nuts to the specified torque
at 100 miles (160 kilometers) and again at 500 miles (800 kilometers) of new vehicle
operation and after any wheel disturbance (such as tire rotation, changing a flat tire,
wheel removal).

It is important to follow the proper wheel mounting and lug nut torque procedures.

E161443

On all two-piece flat wheel nuts,
apply one drop of motor oil
between the flat washer and the
nut. Do not apply motor oil to the
wheel nut threads or the wheel
stud threads.
