Note:To avoid transmission damage, vehicles should not be towed even
a short distance without suspending rear wheels or removing the axle
shafts or driveshaft.
Note:In the event the chassis is equipped with a tandem axle and the
vehicle is to be towed from the front, the forward rear axle may be
raised to clear the road surface and secured to the frame by chains or
U-bolts, allowing only the rear rear axle to contact the road surface. Axle
shafts must be removed from the rear rear axle assembly. The wheel hub
ends must be covered to prevent loss of axle lubricant and entrance of
contaminants. Use extreme care in securing the chains or U-bolts to
avoid possible damage to the brake lines, hoses or other components.
Towing vehicles equipped with a driver-controlled differential lock
Note:If the vehicle must be towed to a service facility with the drive
axle wheels on the ground, it is necessary to remove the axle shafts
before the vehicle is towed.

Removing axle shafts before towing
1. Shift the main differential to the unlocked (disengaged) position; the
differential lock light turns off.
2. Remove the capscrews and washers or stud nuts and washers from
flanges of both axle shafts.
3. Loosen the tapered dowels in the flanges of both axle shafts by
holding a 1
1 2inch diameter brass drift or hammer against the axle shaft
center and hitting it with a five or six pound hammer.Note:Do not use
a chisel or wedge to loosen the axle shafts and dowels. Use of a chisel or
wedge can damage the hub, axle shafts and oil seals.
4. Remove the tapered dowels and both axle shafts from the axle
assembly.
5. Assemble a cover over openings of both wheels ends to prevent loss of
lubricant and keep dirt away from the wheel bearing cavities.
Note:One of the axle shafts has two sets of splines. One set to engage
with the differential side gear and one set to engage with the shift collar
for the differential lock. It may be necessary to rotate the shaft slightly
to align the gear spline teeth with the shift collar teeth in order to
remove the axle shaft.
Installing the axle shafts
1. Remove the covers from the wheel ends.
2. Shift the differential lock to the unlocked (disengaged) position.
3. Install the axle shafts.
•Place the gaskets on the wheel hub studs.
•Push the right-hand axle shaft and gasket into the wheel end and
housing until the shaft stops against the differential shift collar.
•Push down and in on the axle shaft flange and rotate the shaft until
the splines of the shaft and shift collar are engaged.
•Push the axle shaft further into the housing until the shaft stops
against the differential side gear.
•Push down on the axle shaft flange and rotate the shaft until the
splines of the shaft and side gear are engaged.
•Push the axle shaft completely into the housing until the axle shaft
flange and the gasket are flush against the wheel hub.
•Install the left-hand axle shaft and gasket into the wheel end.

4. If tapered dowels are required, install them at each stud and into the
flange of the axle shaft. Use a punch or drift and hammer, if needed.
5. Install the fasteners and tighten to correct torque value. Refer to the
Service Manual.
Towing the vehicle with the rear wheels suspended
Note:To avoid damage to the cab roof or air deflector when towing the
vehicle backward (rear wheels suspended) the air deflector must be
removed.
Whenever possible, it is preferable to tow a disabled vehicle from the
rear by raising the rear of the chassis. When towing a vehicle with the
rear of the chassis suspended, the front wheels must be locked in the
straight-ahead position.
Vehicles equipped with a manual transmission must have at least 1.0 pint
(0.5L) of transmission fluid drained from the case. This prevents the
transmission fluid from entering the clutch housing and fluid saturating
the clutch discs. Make sure that the transmission fluid is replaced before
the vehicle is returned to service.

•Do not allow paint sealant to come in contact with any non-body
(low-gloss black) colored trim, such as grained door handles, roof
racks, bumpers, side moldings, mirror housings or the windshield cowl
area. The paint sealant will “gray” or stain the parts over time.
PAINT CHIPS
Your authorized dealer has touch-up paint to match your vehicle’s color.
Take your color code (printed on a sticker in the driver’s door jamb) to
your authorized dealer to ensure you get the correct color.
•Remove particles such as bird droppings, tree sap, insect deposits, tar
spots, road salt and industrial fallout before repairing paint chips.
•Always read the instructions before using the products.
ALUMINUM WHEELS AND WHEEL COVERS
Aluminum wheels and wheel covers are coated with a clear coat paint
finish. In order to maintain their shine:
•Clean weekly with MotorcraftWheel and Tire Cleaner, which is
available from your authorized dealer. Heavy dirt and brake dust
accumulation may require agitation with a sponge. Rinse thoroughly
with a strong stream of water.
•
Never apply any cleaning chemical to hot or warm wheel rims or covers.
•Some automatic car washes may cause damage to the finish on your
wheel rims or covers. Industrial-strength (heavy-duty) cleaners, or
cleaning chemicals, in combination with brush agitation to remove
brake dust and dirt, could wear away the clear coat finish over time.
•Do not use hydrofluoric acid-based or high caustic-based wheel
cleaners, steel wool, fuels or strong household detergent.
•To remove tar and grease, use MotorcraftBug and Tar Remover ,
available from your authorized dealer.
ENGINE
Engines are more efficient when they are clean because grease and dirt
buildup keep the engine warmer than normal. When washing:
•
Take care when using a power washer to clean the engine. The
high-pressure fluid could penetrate the sealed parts and cause damage.
Note:To prevent damage to the engine control module, never
spray-wash it directly. Never spray any connector.
•Do not spray a hot engine with cold water to avoid cracking the
engine block or other engine components.

INSTRUMENT PANEL/INTERIOR TRIM AND CLUSTER LENS
Clean the instrument panel, interior trim areas and cluster lens with a
clean, damp, white cotton cloth, then use a clean and dry white cotton
cloth to dry these areas.
•Avoid cleaners or polishes that increase the gloss of the upper portion
of the instrument panel. The dull finish in this area helps protect the
driver from undesirable windshield reflection.
•Be certain to wash or wipe your hands clean if you have been in
contact with certain products such as insect repellent and suntan
lotion in order to avoid possible damage to the interior painted
surfaces.
•Do not use household or glass cleaners as these may damage the
finish of the instrument panel, interior trim and cluster lens.
•Do not allow air fresheners and hand sanitizers to spill on interior
surfaces. If a spill occurs,wipe off immediately.Damage may not be
covered by your warranty.
WARNING:Do not use chemical solvents or strong detergents
when cleaning the steering wheel or instrument panel to avoid
contamination of the airbag system.
If a staining liquid like coffee/juice has been spilled on the instrument
panel or on interior trim surfaces, clean as follows:
1. Wipe up spilled liquid using a clean, white, cotton cloth.
2. Wipe the surface with a damp, clean, white cotton cloth. For more
thorough cleaning, use a mild soap and water solution. If the spot cannot
be completely cleaned by this method, the area may be cleaned using a
commercially available cleaning product designed for automotive
interiors.
3. If necessary, apply more soap and water solution or cleaning product
to a clean, white, cotton cloth and press the cloth onto the soiled
area–allow this to set at room temperature for 30 minutes.
4. Remove the soaked cloth, and if it is not soiled badly, use this cloth to
clean the area by using a rubbing motion for 60 seconds.
5. Following this, wipe area dry with a clean, white, cotton cloth.

GENERAL SERVICING GUIDELINES AND PRECAUTIONS
Always use care when performing vehicle maintenance, repairs or system
checks. Improper or incomplete service could result in the vehicle not
working properly which may result in personal injury or damage to the
vehicle or equipment. It is the operator’s responsibility to see that the
vehicle receives proper care and maintenance. If you have any questions
about performing service, have the service done by a qualified
technician.
Servicing guidelines
When servicing your vehicle, always:
•wear safety glasses for eye protection.
•do not wear loose-fitting clothing, hanging jewelry, watches or rings.
•do not smoke.
•set the parking brake or chock the wheels.
•use support stands, not a jack, when working under a raised vehicle.
•turn off the ignition unless a procedure requires the engine to be
running.
•operate the engine in a well-ventilated area.
•do not work on the brakes or the clutch unless the proper precautions
are taken to avoid inhaling friction material dust.
•avoid contact with hot metal parts. Allow the components to cool
before working with, or around, them.
Quality service parts are available through your dealer. If dealer parts are
not used, make sure the replacement parts are of equivalent quality.
WARNING:The use of inferior parts can adversely affect the
quality and reliability of your vehicle which, in turn, can result in
property damage, personal injury or death.
Note:To avoid damage to the vehicle’s electrical components prior to
electric welding:
•disconnect both battery cables.
•attach the welder ground cable as close as possible to the part being
welded.
•if it is necessary to weld close to an electrical component, it is
recommended that the component be temporarily removed.
Maintenance and Specifications

2012 F-650/750(f67)
Supplement, 2nd Printing
USA(fus)
At regular intervals, or during other scheduled maintenance (tire
rotation/service, wheel bearing service, alignment, etc.), the kingpins
should be checked for excessive wear. Refer to the service manual for
proper procedures.
Toe-in setting - general inspection
Inspecting steer axle tires in the first 3,000–10,000 service miles
(5,000–16,000 service km) generally shows if tires are wearing normally.
Rapid outside shoulder wear on both tires indicates too much toe-in.
Rapid inside shoulder wear on both tires indicates too much toe-out. In
P&D-type service, left-to-right steer tire tread life differentials up to 40%
can be observed depending on routes and other variables.
Follow the tire manufacturer’s recommended cold inflation pressure for
the tire size, load range (ply rating) and steer axle loading typical for
their operation (each steer axle tire equals
1 2steer axle loading).
Special applications may warrant a setting based on experience with the
type of tire operating loads and conditions. Radial tires are more
sensitive to toe-in setting than bias ply tires. While not insensitive to
vehicle alignment, fine tuning school bus alignment to line-haul truck
standards does not drastically improve tire tread life.
It is essential that correct toe-in and tire pressure be maintained for
optimum tire wear.
Rear axle - general inspection
Make sure that the axle mounting U-bolts, attaching or mounting bolts
and nuts are securely tightened. Refer toU-bolt nut torquein this
chapter. Regularly check the rear axle for damaged, binding or worn
parts.
NoSpin Detroit Locker positive locking differential
Vehicles equipped with this type differential have the operator’s manual
supplied with the vehicle. Refer to this manual for maintenance checks.
