2013 FORD F750 maintenance

BREAKING-IN
You need to break in new tires for approximately 300 miles
(480 kilometers). During this time, your vehicle may exhibit some unique
driving characteristics. Avoid driving too fast during the first 1000 miles
(1600 kilometers). Vary your speed frequently and change up through
the gears early. Do not labor the engine.
ECONOMICAL DRIVING
Fuel economy is affected by several things such as how you drive, the
conditions you drive under and how you maintain your vehicle.
There are some things to keep in mind that may improve your fuel
economy:
•Accelerate and slow down in a smooth, moderate fashion.
•Drive at steady speeds without stopping.
•Anticipate stops; slowing down may eliminate the need to stop.
•Close the windows for high-speed driving.
•Drive at reasonable speeds (traveling at 55 mph [88 km/h] uses 15%
less fuel than traveling at 65 mph [105 km/h]).
•Keep the tires properly inflated and use only the recommended size.
•Use the recommended engine oil.
•Perform all regularly scheduled maintenance.
There are also some things you may not want to do because they may
reduce your fuel economy:
•Sudden or hard accelerations.
•Warm up your vehicle on cold mornings.
•Use the air conditioner or front defroster.
•Use the speed control in hilly terrain.
•Rest your foot on the brake pedal while driving.
•Carry unnecessary weight (approximately 1 mpg [0.4 km/L] is lost for
every 400 pounds [180 kilograms] of weight carried).
•Add particular accessories to your vehicle (e.g., bug deflectors,
rollbars and light bars, running boards, ski racks).
•Drive with the wheels out of alignment.

GENERAL INFORMATION
WARNING:Making modifications to various parts, components
and systems of the vehicle, such as brake and steering systems,
can adversely affect the quality, reliability and operation of your vehicle
and could result in property damage, personal injury or death. Such
modifications must be avoided.
WARNING:Failure to properly perform maintenance and
servicing procedures could result in vehicle damage, personal
injury or death.
WARNING:Take care when performing any maintenance,
system check or service on your vehicle. Some of the materials
may also be hazardous if used, serviced or handled improperly and
could result in property damage, personal injury or death.
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.
•always set the parking brake or chock the wheels.
•always use support stands, not a jack, when working under a raised
vehicle.
•always turn off the ignition unless a procedure requires the engine to
be running.
•always avoid contact with hot metal parts. Allow the components to
cool before working with, or around, them.
•always operate the engine in a well-ventilated area.
•do not wear loose-fitting clothing, hanging jewelry, watches or rings.
•do not smoke.
•do not work on the brakes or the clutch unless the proper
precautions are taken to avoid inhaling friction material dust.
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.
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.
•it is recommended that the component be temporarily removed if
welding close to an electrical component.
Follow the checks and services in theScheduled Maintenancechapter.
Have your dealer or service center inspect your vehicle at least once a
year. Remember that regular maintenance and inspections usually
prevent serious problems from developing later.
If the owner or operator of the vehicle is a skilled technician and intends
on performing the vehicle maintenance and service, he is strongly urged
to purchase a service manual.
Electrical System
Periodically inspect electrical connectors on the outside of the cab and
on the engine and frame for corrosion and tightness. Exposed terminals,
such as the fuel sender, cranking motor, alternator and feed-through
studs, should be cleaned and re-coated with a lubricant sealing grease
such as Motorcraft® Silicone Brake Caliper Grease and Dielectic
Compound XG-3, or equivalent. This should include the ground cable
connector for batteries, engine and cab as well as the jump starting stud.
Accessory Feed Connections
Vehicle electrical systems are complex and often include powertrain
components, such as engine and transmission controls, instrument
panels, ABS, etc. While most systems operate on battery voltage
(12 volts), some systems can be as high as 90 volts or as low as five
volts. See theElectrical Circuit Diagram Manuals,available from your
vehicle’s manufacturer, to make sure that any additional body lights and
accessories are connected to circuits that are both appropriate and not
overloaded. No modification should be made to any vehicle control
system without first contacting your dealer.

Climate Control System
Have the air conditioning system checked each spring. The refrigerant
charge, cleanliness of the condenser-evaporator cores and belt condition
are essential to system performance.
When the air conditioning system is being used daily, remove the fresh
air filter (if equipped) once each season and check for dirt, lint, etc.
Replace the filter if necessary. Vehicles operating in unusually dusty
conditions may require more frequent filter inspection and replacement.
Front Axle
Maintaining the front axle alignment to specifications is very important
and should only be performed by a qualified technician. Regular
inspections should include:
•toe-in inspection and adjustment (if necessary), particularly with
radial tires.
•checking for proper tightness of axle mounting U-bolt nuts, attaching
or mounting bolts and nuts.
•checking the axle for damage, binding, worn parts and adequate
lubrication..
•checking the kingpins for excessive wear. This should also be done
during other scheduled maintenance (tire rotation or service, wheel
bearing service, alignment, etc.). See the workshop manual for proper
procedures.
Toe-in
It is essential that correct toe-in and tire pressure be maintained for
optimum tire wear.
Inspecting steer axle tires in the first 3000–10000 service miles
(5000–16000 service kilometers) 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
12steer 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.
Rear Axle
Regular inspections should include:
•checking for proper tightness of axle mounting U-bolt nuts, attaching
or mounting bolts and nuts. SeeSpring U-bolt checkslater in this
chapter.
•checking the axle for damage, binding, worn parts and adequate
lubrication.
NoSpin Detroit Locker Positive Locking Differential
Vehicles equipped with this type differential have the operator’s manual
supplied with the vehicle. See that manual for maintenance inspections.

Brake System
Note:Persons handling brake linings should follow all precautions listed
below:
WARNING:
1. Always wear a respirator approved by the National Institute of
Occupational Studies of Health (NIOSH) or Mine Safety and Appliance
(MSA) during all brake service procedures. Wear the respirator from
removal of the wheels through assembly.
2.Neveruse compressed air or dry brushing to clean brake parts or
assemblies.
3. Clean brake parts and assemblies in open air. During assembly,
carefully place all parts on the floor to avoid getting dust in the air. Use
an industrial vacuum cleaner with a HEPA filter system to clean dust
from the brake drums, backing plates and other brake parts. After using
the vacuum, remove any remaining dust with a rag soaked in water and
wrung until nearly dry.
4.Neveruse compressed air or dry sweeping to clean the work area.
Use an industrial vacuum cleaner with a HEPA filter system and rags
soaked in water and wrung until nearly dry. Dispose of used rags with
care to avoid getting dust in the air. Use an approved respirator when
emptying vacuum cleaners and handling used rags.
5.Worker clean-up:Wash your hands before eating, drinking or
smoking. Vacuum your work clothes after use and then launder them
separately, without shaking them, to prevent fiber dust getting into the
air.
Your vehicle is equipped with non-asbestos brake linings. However,
exposure to excessive amounts of brake material (whether asbestos or
non-asbestos, fiberglass, mineral wool, aramid or carbon) may be a
serious health hazard.
