Ford F 750 Owners Manual

							To make sure the emissions control
systems operate effectively, you should
have the services listed in the maintenance
schedule performed at the specified time
and mileage intervals. You should avoid
running out of fuel or turning off the ignition
when your vehicle is moving, especially at
high speeds.
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 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 an authorized dealer. Be alert
for fluid leakage, odor, smoke, loss of oil
pressure, or charge indicator or over
temperature warning.
Vehicles equipped with a diesel engine
cannot use diesel fuel blended with waste
oil if equipped with a catalytic
converter-muffler. Waste lube oil blending
in fuel plugs the catalytic
converter-muffler, resulting in a significant
loss of engine power.
Noise Emissions Warranty, Prohibited
Tampering Acts and Maintenance
On January 1, 1978, Federal regulations
became effective governing the noise
emissions on trucks over 10000 pounds
(4536 kilograms) GVWR. The following
statements concerning prohibited
tampering acts and maintenance and the
noise warranty are found in the warranty
information, 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:
Acts
Vehicle system
Removal of noise shields, hood blanket, tunnel liner oracoustical absorptive material.
Acoustical shielding
Removal or rendering inoperative the engine speed
governor to allow engine speed to exceed manufacturer specifications. Removal of engine mounted noise shield or oil pan enclosure.
Engine
Removal of the air duct, silencer, air cleaner, and/or air
cleaner element and baffle in air cleaner; re-indexing of air cleaner.
Engine air induction

							Acts
Vehicle system
Removal or rendering inoperative exhaust system
components including the catalytic converter - muffler
assembly, inlet pipe, outlet pipe, resonator and flex pipe. Rotation of horizontal exhaust system directional outlet pipe to cause the exhaust to be emitted in a directionother than the orientation your vehicle was originally produced with.
Exhaust
Removal or rendering inoperative the fan clutch. Removalor modification of the fan shroud. Replacing a fixed fan with a fan of increased diameter, different number of blades or different pitch width.
Engine cooling
Removal or rendering inoperative DEF system compon-
ents including the DEF tank, dosing module, dosing supply module, dosing control unit, NOx electronic module or NOx sensor.
DEF (Diesel exhaust fluid)
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.
Maintenance
Instructions for maintenance and service
of the noise control system have been
included in the required maintenance
services and in the general maintenance
section. To further help minimize noise
emissions degradation throughout the life
of your vehicle, Ford Motor Company
recommends that you operate this vehicle
in the manner described within this owner ’s manual. Caution should be exercised by
the owner when installing replacement
parts to be sure that a tampering act (as
outlined above) is not committed. Note
any inspection and service performed in
the maintenance log.
Emissions Information Label
Emissions information appears on the
Important Engine Information decal
located on or near the engine.
Scheduled Maintenance Services
Maintenance service adjustments must
conform to specifications contained in this
manual, and those shown on the Important
Engine Information decal. Perform the
following services at scheduled intervals
because they essential to the life and
performance of your vehicle. Ford
recommends that you perform
maintenance on all designated items to
achieve best vehicle operation.
319
F-650/750 (TBC) , enUSA, First Printing Scheduled Maintenance 
						

							There are three types of maintenance
intervals for general vehicle environments:
On-Highway, City and Severe Service. In
all applications, monitoring miles
(kilometers) and time and when the engine
is due for an oil change determine the
actual interval. When the engine oil change
is required before the truck lubrication
interval, perform the lubrication at the
same time in order to reduce your vehicle
’s
time out of service.
Air Brake Adjustment WARNING
Failure to maintain proper air brake
adjustment can result in reduction
or loss of braking ability.
A qualified service technician, keeping to
the instructions in the service manual,
should perform air brake inspection and
adjustment or repairs.
Cam Brakes - Automatic Slack
Adjusters
WARNING
Do not manually adjust the
automatic slack adjusters to correct
excessive push rod stroke as it may
result in reduced brake effectiveness and
a vehicle crash. Excessive push rod stroke
indicates that a problem exists with the
automatic adjuster, with the installation
of the adjuster, or with foundation brake
components that manual adjustment does
not remedy. Seek service from a qualified
facility for excessive push rod stroke. Inspect standard air brakes equipped with
automatic slack adjusters for proper brake
adjustment as listed in the maintenance
schedule charts.
However, inspect the brakes more
frequently when subjecting them to heavy
use or adverse operating conditions such
as:
•
Frequent brake applications while fully
loaded.
• Operation on hilly or mountainous
terrain.
• Frequent operation on dirt, gravel or
mud.
Some aftermarket brake linings also
require more frequent inspections.
Owner Checks and Services
Make sure you perform the following basic
maintenance checks and inspections every
month or at six-month intervals.

(800 km) after any wheel disturbance (such as tire rota-
tion, changing a flat tire or wheel removal).
Single rear wheels
Tighten the wheel lug nuts to the specified torque *

Dual rear wheels
*  See Technical Specifications (page 250).
Multi-point Inspection
In order to keep your vehicle running right,
it is important to have the systems on your
vehicle checked regularly. This can help
identify potential issues and prevent major
problems. We recommend having the
following multi-point inspection performed
at every scheduled maintenance interval
to help make sure your vehicle keeps
running great. Multi-point inspection
Horn operation
Accessory drive belt(s)
Radiator, cooler, heater and A/C hoses
Battery performance
Suspension component for leaks ordamage
Engine air filter

Be sure to ask your dealership service
advisor or technician about the multi-point
vehicle inspection. It is a comprehensive
way to perform a thorough inspection of
your vehicle. Your checklist gives you
immediate feedback on the overall
condition of your vehicle.
NORMAL SCHEDULED
MAINTENANCE
Intelligent Oil-Life Monitor™
(Diesel Engine Only)
Your diesel engine is equipped with an
Intelligent Oil-Life Monitor that determines
when you should change the engine oil
based on how your vehicle is used. By using
several important factors in its
calculations, the monitor helps reduce the
cost of owning your vehicle and reduces
environmental waste at the same time. This means you do not have to remember
to change the oil on a mileage-based
schedule. Your vehicle lets you know when
an oil change is due by displaying a
message in the information display.
The following table provides examples of
vehicle use and its impact on oil change
intervals. It is a guideline only. Actual oil
change intervals depend on several factors
and generally decrease with severity of
use.
When to expect the message prompting you to change your oil
