SERVICING YOUR WHEELS AND TIRES
Wheel assembly
Your vehicle is fitted with hub
piloted wheels and two-element
swiveling lug nuts (20 & 22 mm).
Do not use taper type wheels or ball
seat wheel nuts.
²Do not paint the mating face of the hub/drum.
²Do not paint the two-element swiveling lug nuts or wheel stud.
²Do not allow an excessive thickness of paint to build between the disc
wheel mounting surfaces.
²Do not install disc wheels where the paint has not fully cured.
²At wheel changes, ensure mounting faces are clean and free of rust,
dirt and excess paint.
If fasteners are needed, use only Ford recommended replacement parts.
²To maintain the desired
torque/tension relation between
nut body and flange, it is
necessary to use clean engine oil
meeting Ford specification
WSS-M2C153-G between nut body and flange. Lubricate the nut body
and flange any time a wheel is removed.
Maintenance and Specifications
215
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.

For troubleshooting information, refer to the diesel engine operator's
manual.

If engine cranks but won't start
For troubleshooting information, refer to the engine operator's manual.
If engine runs hot
For troubleshooting information, refer to the engine operator's manual.
If fuses burn out
Burned-out or ªblown-outº fuses or circuit breaker tripping (if equipped)
usually indicate an electrical short circuit, although a fuse may
occasionally fail from vibration. Insert a second fuse or reset the breaker
(if equipped). If this fuse immediately burns out or the breaker (if
equipped) trips and you cannot locate the fuse, return your vehicle to
your dealer for a circuit check.
If lamp bulbs burn out
Repeated lamp burn-out usually indicates a loose connection, either at
the lamp socket, the system ground or a malfunctioning voltage
regulator. If examination does not indicate the cause of the trouble,
return your vehicle to your dealer for inspection.
If headlamps flash on and off
If headlamps flash on and off at regular intervals, the system circuit
breaker (if equipped) is operating, indicating a short circuit or overload.
Take your vehicle to your dealer for a circuit check.

Maintenance and Specifications
227
OWNER MAINTENANCE
You can do much of the maintenance your vehicle requires yourself, if
you have the time and a reasonable amount of mechanical ability. If you
prefer to have this work done professionally, your authorized dealer
stands ready to help you.
All mechanical components and attachments are important in that they
could affect the performance of vital components and systems. If
replacement becomes necessary, they must be replaced with parts having
the same part number or with equivalent parts. Torque values of the
attaching parts must be used as specified during any reassembly
procedure to assure proper retention.
EMISSIONS CONTROL SYSTEM
To assure the emissions control systems operate effectively, you should
have the services listed in the maintenance schedule performed at the
specified time and km/mileage intervals. You should avoid running out of
fuel or turning off the ignition while the vehicle is in motion, especially
at high speeds.
Because of high engine compartment and exhaust system
temperatures resulting from emissions equipment, do not park,
idle or operate your vehicle in dry grass or other dry ground cover
where the possibility of ground fire exists.
Do not make unauthorized modifications to the engine or vehicle.
Modifications causing increased amounts of unburned fuel to reach the
exhaust system can significantly increase the temperature of the engine
compartment and/or the exhaust system.
Avoid driving your vehicle if it does not operate properly. If the engine
diesels (more than five seconds of engine run-on after shut-off), misfires,
surges, stalls or backfires, see your dealer. Be alert for fluid leakage,
odor, smoke, loss of oil pressure, or charge indicator or over temperature
warning.
Do NOT use diesel fuel blended with waste oil in engines equipped with
a CATALYTIC CONVERTER-MUFFLER. Waste lube oil blending in fuel
will plug the CATALYTIC CONVERTER-MUFFLER, resulting in a
significant loss of engine power.
General Maintenance Information
231
Emissions control system(s) laws
Federal law prohibits vehicle manufacturers, dealers and other persons
engaged in the business of repairing, servicing, selling, leasing or trading
motor vehicles, as well as fleet operators from knowingly removing or
rendering an emissions control device or system inoperative. Further,
modifications of the emissions control system(s) could create liability on
the part of individual owners under the laws of some states. In Canada,
modification of the emissions control system could create liability under
applicable Federal or Provincial laws.
NOISE EMISSIONS WARRANTY, PROHIBITED TAMPERING ACTS
AND MAINTENANCE
On January 1, 1978, Federal regulations became effective governing the
noise emissions on trucks over 4 535 kgs. (10 000 lbs.) GVWR. The
following statements concerning prohibited tampering acts and
maintenance and the noise warranty are found in the Warranty Guide,
and are applicable to completed trucks.
Tampering with noise control system prohibited
Federal law prohibits the following acts or the causing thereof: (1) The
removal or rendering inoperative, by any person other than for purposes
of maintenance, repair or replacement, of any device or element of
design incorporated into any new vehicle for the purpose of noise control
prior to its sale or delivery to the ultimate purchaser or while it is in use,
or (2) the use of the vehicle after such device or element of design has
been removed or rendered inoperative by any person.
Among those acts presumed to constitute tampering are the following
acts listed:
Vehicle System Acts
Acoustical Shielding Removal of noise shields, hood blanket,
tunnel liner or acoustical absorptive
material.
Engine Removal or rendering inoperative the
engine speed governor so as to allow
engine speed to exceed manufacturer
specifications. Removal of engine mounted
noise shield or oil pan enclosure.
