    							In areas where road salt is used,
    disassemble the joints of each aluminum
    component and inspect for salt build-up
    and presence of chlorine that can cause
    aluminum particles to flake off and enter
    the engine combustion chambers. If
    evidence of corrosion is found (usually at
    the pipe connections), use a wire brush to
    clean the inside of the pipes and inside the
    rubber hoses.
    If pitting is evident at the joint ends of the
    intake pipes, use Motorcraft Silicone
    Gasket and Sealant TA-30 to seal the
    joints. Make sure no excess material, which
    can pull into the engine, is on the inside of
    the pipes. If the service condition of the
    pipes, hoses or clamps is questionable,
    replace the defective part(s).
    Make sure to clean all dust and debris out
    of the pipes and couplings with a clean,
    damp rag before reassembly.
    Chassis-mounted Charge Air
    Cooler
    Visually inspect the core assembly for
    debris and clogging of external fins with
    the engine off.
    Before engine operation, remove any debris
    blocking the core.
    •
    Turbocharger-to-charge air cooler.
    • Charge air cooler-to-intake manifold
    pipe.
    • Mounting bracket.
    • Chassis-mounted charge air cooler
    core.
    Inspect air intake piping:
    • Check for accumulation of salt
    deposits (where applicable). If present,
    disassemble and clean the complete
    air intake piping system. If pitting is
    evident on the intake piping, use
    Motorcraft Silicone Gasket and Sealant
    TA-30 to seal joints against leakage.
    • Check for loose hoses and clamps. •
    Check for ruptured or collapsed hoses.
    • Check air cleaner housing for cracks.
    EXHAUST SYSTEM
    INSPECTION
    Note: If your vehicle is equipped with a
    catalytic converter or muffler, do not blend
    waste oil with diesel fuel. Operate only on
    ultra-low sulfur (less than 15 parts per
    million sulfur) diesel fuel with a cetane
    value of 45 or higher.
    If your diesel engine is equipped with a
    catalytic converter, it is important to review
    the maintenance schedule to make sure
    proper functioning of the catalytic
    converter. Also, take precautions not to
    damage the catalytic converter when
    servicing your engine or storing your
    vehicle.

    							BRAKE SYSTEM INSPECTION
    WARNING
    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.
    Never use compressed air or dry brushing
    to clean brake parts or assemblies.
    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.
    Never use 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.
    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. Air Brakes 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. Inspection and Adjustment
    Establish a regular schedule for periodic
    cleaning, lubrication and adjustment
    inspection based on vehicle use. Exact
    maintenance intervals are difficult to
    predetermine due to vehicle applications
    and operating conditions. If you are
    uncertain of the proper schedule for your
    vehicle, contact an authorized dealer.
    Regular inspections should include:
    •
    Periodic checking (every service
    interval) of push rod travel or brake
    adjustment. This is essential for
    effective braking. Brake chamber push
    rods on original equipment chambers
    now incorporate an orange paint
    marker near the base of the push rod
    219
    F-650/750 (TBC) , enUSA, First Printing Maintenance 
    						
    							as a stroke indicator to aid in
    adjustment checks. If the push rod is
    clean and the brakes are out of
    adjustment, you can see the orange
    marker protruding from the chamber
    when the brakes are applied.
    • Checking the brake lining (every service
    interval). When brake linings or blocks
    wear within 0.063 in (1.6 mm) they
    must be replaced.
    • Periodic checking (every service
    interval) of the air compressor filter.
    Check the filter minder and when the
    indicator is near or on the red line
    marked 
    Service, replace the filter and
    reset the service filter minder.
    Do not back off or disconnect the front
    brakes so that they are less effective,
    letting the rear brakes do all the stopping
    of your vehicle. Do not overlook the brakes
    on the trailer either. Brake condition on the
    trailer is just as important as the tractor.
    Proper brake balance on trucks and
    tractor-trailers is essential for effective
    braking.
    Once a year, inspect the entire brake
    system:
    • Rubber components for deterioration.
    A qualified technician should inspect
    these components and replace them
    as necessary. Replacement intervals
    vary according to the severity and
    length of vehicle service.
    • Condition of brake drums, brake
    chambers and slack adjusters.
    • System for air leaks.
    • Hose or pipes for rust, damage and
    deterioration.
    • Operation of service and parking
    brakes.
    Periodically inspect parts such as air brake
    chamber diaphragm, air compressor and
    air cleaner. Replace any parts if you can
    consider them unserviceable. Air Dryer
    Climactic conditions affect performance
    of desiccant or after-cooler type air dryers.
    You must establish a maintenance
    schedule for each specific operation.
    The use of an air dryer on a vehicle does
    not eliminate the need to drain the air
    reservoirs periodically.
    Inspect for moisture in the air system by
    opening reservoirs, draincocks or valves
    and checking for presence of water. The
    presence of small amounts of water due
    to condensation is normal and is not an
    indication that the dryer is not functioning
    properly.
    Replace or rebuild the desiccant cartridge
    when you determine that the desiccant is
    contaminated and does not have adequate
    water absorption capacity. The desiccant
    change interval may vary. A general
    recommendation is to replace the
    desiccant every 12 months (yearly). If
    experience has shown that extended or
    shortened life has resulted for a particular
    installation, then the yearly interval can be
    increased or decreased accordingly.
    Draining the Air Brake Reservoir
    WARNING
    Failure to drain air brake reservoirs
    can result in a reduction or loss of
    braking ability due to fluid
    accumulation in the reservoir and/or
    possible freeze-up during cold weather. Completely drain all the air brake reservoirs
    daily by opening the draincock at the ends
    of the tanks. (Where accessible.
    Pull-chains are used when the drains are
    undercab or otherwise inaccessible.) Close
    the draincock after draining. Manually drain
    220
    F-650/750 (TBC) , enUSA, First Printing Maintenance 
    						
    							any air tanks equipped with automatic
    moisture ejector valves, as required, to
    maintain a dry air system. Contact an
    authorized dealer if you are unsure of the
    air reservoir locations or the draining
    procedure.
    Hydraulic Brakes
    Establish a regular schedule for periodic
    cleaning, lubrication and adjustment
    inspection based on vehicle use. Exact
    maintenance intervals are difficult to
    predetermine due to vehicle applications
    and operating conditions. If you are
    uncertain of the proper schedule for your
    vehicle, contact an authorized dealer.
    Regular inspections should include:
    •
    Checking the brake lining (every service
    interval). Establish inspection intervals
    that provide for lining replacement
    before damage to the disc occurs.
    Excessive lining wear may expose the
    backing plate to the disc causing
    scoring of the disc faces. A qualified
    technician should perform this inspection and keep to instructions
    provided by the service manual.
    Hydraulic brake systems are
    power-assisted. There is a great
    reduction in braking capabilities
    without engine assist.
    • Proper fluid level. The level should be
    at the bottom edge of the ring on each
    reservoir fill port. Do not fill the master
    cylinder to the top of the reservoir. If
    fluid level requires attention to
    maintain a proper master cylinder level,
    this is an indication of either severe
    operation (pad wear) or fluid leakage.
    A more frequent and thorough brake
    inspection is required.
    • Brake lines, hoses and fittings. Repair
    or replace brake line tubes, hoses or
    fittings as required. Inspect these
    components every 4,000 mi
    (6,000 km) for the following.
    • Lines for kinks, dents, corrosion or
    rupture.
    • Hoses for abrasions, kinks, soft
    spots or rupture, collapse, cracks,
    twists or loose frame supports.
    When replacing a hose, be sure
    there is adequate clearance to the
    hose to avoid an abrasion to the
    new hose.
    • All connections for leaks.
    Driveline Parking Brake WARNING
    Use wheel chocks and exercise
    caution when inspecting under the
    vehicle. A vehicle roll-away could
    result in property damage, personal injury
    or death. A qualified technician should adjust the
    parking brake and keep to the instructions
    in the service manual.
    221
    F-650/750 (TBC) , enUSA, First Printing Maintenance 
    						
    							AXLE INSPECTION
    Front Axle
    Maintaining the front axle alignment to
    specifications is very important. A qualified
    technician should check and maintain the
    alignment.
    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. Also, perform this check during
    other scheduled maintenance, for
    example as tire rotation or service,
    wheel bearing service and alignment.
    See the workshop manual for proper
    procedures.
    Toe-in
    It is essential to maintain correct toe-in
    and tire pressure for optimum tire wear.
    Inspecting steer axle tires in the first
    3,000– 10,000 mi (5,000– 16,000 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, there can be a
    left-to-right steer tire tread life differential
    up to 40% 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 ½ steer 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. Fine tuning school bus
    alignment to line-haul truck standards
    does not drastically improve tire tread life.
    STEERING SYSTEM
    INSPECTION
    WARNING
    Failure to maintain the steering
    system in proper condition can cause
    reduced steering ability resulting in
    property damage, personal injury or death. Note:
    Have any steering problems
    immediately corrected by a qualified service
    technician.
    Ask your service technician to examine the
    steering mechanism. Only minor
    adjustments may be necessary.
    Regular inspections should include:
    • Checking the tie rod, drag link end
    clamp bolts and ball joints for proper
    tightness.
    • Checking for installation and spread of
    cotter pins and tightness of nuts at
    both ends of the tie rod and drag link.
    • Checking that the pitman arm (steering
    arm at steering gear) mounting is tight
    and locked. Check system for leaks or
    hose chafing. Repair immediately, if
    necessary.
    222
    F-650/750 (TBC) , enUSA, First Printing Maintenance 
    						
    							•
    Maintaining proper steering gear and
    power steering pump lubricant levels.
    • Checking steering column joint bolts
    and steering linkage, particularly for
    body-to-chassis clearance.
    Steering Column Joint Bolts
    As a good maintenance practice, check
    steering column joint bolt tightness every
    60,000 mi (96,000 km) or annually,
    whichever occurs first. Do not overtighten
    the bolts.
    Hydraulic System
    Whenever draining and refilling the power
    steering's hydraulic system for any reason,
    bleed air from the system before returning
    the vehicle to service. Failure to bleed the
    hydraulic system properly can result in
    degradation of power system performance.
    Consult an authorized dealer who is aware
    of the proper procedures for filling and
    bleeding the system.
    SUSPENSION SYSTEM
    INSPECTION
    Note: Do not adjust air suspension height
    to any setting other than the specified
    setting. Altering the height setting changes
    the driveline angle and may result in
    unwarrantable component damage, such
    as transmission component damage.
    Verify drive axle air suspension height and
    height control valve performance at engine
    oil change intervals.
    Periodically check:
    • Condition of spring leaves for evidence
    of fatigue, bending or breakage.
    • Condition of suspension mounting
    brackets and bushings.
    • Torque rod mounting fasteners for
    tightness. •
    For proper suspension alignment.
    Maintain proper alignment at all times.
    • U-bolts. After the chassis has been
    operating under load for 
    1,000 mi
    (1,600 km) or six months (whichever
    comes first), the U-bolt nuts must be
    re-torqued. Re-torque the U-bolt nuts
    every 
    37,000 mi (60,000 km)
    thereafter. Clean and lubricate the
    U-bolt and nut threads and seats to
    make sure a like new condition when
    re-torqueing.  See 
    Spring U-Bolt
    Check (page 224).
    FRAME AND TOW HOOK
    INSPECTION
    Your vehicle's chassis is manufactured
    with frame rails of either HSLA steel or
    heat-treated steel. Handle each in a
    specific manner to make sure maximum
    service life. Consult the service manual or
    an authorized dealer before attempting
    frame repair or modification.
    It is important, particularly on vehicles that
    use tow hooks frequently, to inspect the
    front and rear tow hooks for damage or a
    loose mounting.
    REAR AXLE FLUID CHECK
    Your rear axle may have an optional
    synthetic lubricant that allows the use of
    extended service intervals. A tag on the
    filler plug identifies the use of the synthetic
    lubricant.
    Only use a lubricant that meets
    manufacturer specifications. Only use a
    lubricant that meets manufacturer
    specifications. Use of a non-approved rear
    axle lubricant may cause internal axle
    component damage.  See Capacities and
    Specifications
     (page 258).
    223
    F-650/750 (TBC) , enUSA, First Printing Maintenance 
    						
    							Checking the Fluid Level
    1. Park your vehicle on level ground.
    2. Set the parking brake and shift into
    position neutral (N) or park (P). Turn
    the engine off.
    3. Clean any dirt from around the axle filler plug.
    4. Remove the filler plug and inspect the lubricant level. It should be at the
    bottom of the filler plug opening.
    5. Add lubricant, if necessary, through the
    filler plug opening.
    6. Clean and install the filler plug securely.
    Changing the Fluid
    Note: Drain the rear axle while the lubricant
    is warm.
    1. Park your vehicle on level ground.
    2. Set the parking brake and shift into position neutral (N) or park (P). Turn
    the engine off.
    3. Clean any dirt from around the axle filler and drain plugs.
    4. Remove the filler and drain plugs. Drain
    the lubricant into a suitable container.
    Dispose of all used automotive fluids
    in a responsible manner following your
    local authorized standards.
    5. Clean and install the drain plug securely.
    6. Add lubricant through the filler plug opening.
    7. Clean and install the filler plug securely.
    SPRING U-BOLT CHECK
    Check and tighten the U-bolt nuts after
    your vehicle has been operated under load
    for 1,000 mi (1,600 km) or six months,
    whichever occurs first. Thereafter, install new U-bolt nuts and
    washers every 
    36,000 mi (58,000 km).
    Check and tighten the U-bolt nuts with
    your vehicle at curb height and unloaded.
    Inspect the U-bolt threads for rust and
    debris. Clean the threads if contaminated.

    CLEANING THE EXTERIOR
    Wash your vehicle regularly with cool or
    lukewarm water and a neutral pH
    shampoo, we recommend Motorcraft
    Detail Wash.
    • Never use strong household detergents
    or soap, for example dish washing or
    laundry liquid. These products can
    discolor and spot painted surfaces.
    • Never wash your vehicle when it is hot
    to the touch, or during strong or direct
    sunlight.
    • Dry your vehicle with a chamois or soft
    terry cloth towel to eliminate water
    spotting.
    • Immediately remove fuel spillages, bird
    droppings, insect deposits and road tar.
    These may cause damage to your
    vehicle ’s paintwork or trim over time.
    We recommend Motorcraft Bug and
    Tar Remover.
    • Remove any exterior accessories, for
    example antennas, before entering a
    car wash.
    Note: Suntan lotions and insect repellents
    can damage painted surfaces. If these
    substances come in contact with your
    vehicle, wash the affected area as soon as
    possible. Exterior Chrome Parts
    •
    Apply a high quality-cleaning product
    to bumpers and other chrome parts.
    Follow the manufacturer ’s instructions.
    We recommend Motorcraft Custom
    Bright Metal Cleaner.
    • Do not apply the cleaning product to
    hot surfaces. Do not leave the cleaning
    product on chrome surfaces longer
    than the time recommended.
    • Using other non-recommended
    cleaners can result in severe and
    permanent cosmetic damage.
    Note: Never use abrasive materials, for
    example steel wool or plastic pads as they
    can scratch the chrome surface.
    Note: Do not use chrome cleaner, metal
    cleaner or polish on wheels or wheel covers.
    Exterior Plastic Parts
    For routine cleaning we recommend
    Motorcraft Detail Wash. If tar or grease
    spots are present, we recommend
    Motorcraft Bug and Tar Remover.

    drain holes free of debris or foreign
    material.
    Under Hood
    For removing black rubber marks from
    under the hood we recommend Motorcraft
    Wheel and Tire Cleaner or Motorcraft Bug
    and Tar Remover.
    WAXING
    Regular waxing is necessary to protect your
    car's paint from the elements. We
    recommend that you wash and wax the
    painted surface once or twice a year.
    When washing and waxing, park your
    vehicle in a shaded area out of direct
    sunlight. Always wash your vehicle before
    applying wax.
    • Use a quality wax that does not contain
    abrasives.
    • Follow the manufacturer ’s instructions
    to apply and remove the wax.
    • Apply a small amount of wax in a
    back-and-forth motion, not in circles. •
    Do not allow wax to come in contact
    with any non-body (low-gloss black)
    colored trim. The wax will discolor or
    stain the parts over time.
    •Roof racks.
    • Bumpers.
    • Grained door handles.
    • Side moldings.
    • Mirror housings.
    • Windshield cowl area.
    • Do not apply wax to glass areas.
    • After waxing, your car's paint should
    feel smooth, and be free of streaks and
    smudges.
    CLEANING THE 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.
    • Do not spray a hot engine with cold
    water to avoid cracking the engine
    block or other engine components.
    • Spray Motorcraft Engine Shampoo and
    Degreaser on all parts that require
    cleaning and pressure rinse clean. In
    Canada, use Motorcraft Engine
    Shampoo.
    • Never wash or rinse the engine while it
    is hot or running; water in the running
    engine may cause internal damage.
