2011 FORD F650 steering

Diesel exhaust fluid (DEF), Diesel particulate filter (DPF) and Select
catalyst reduction (SCR) system
Refer to your engine operator’s manual for information regarding DEF,
DPF and SCR system service.
Air induction system
Once each year, perform a complete inspection of the air induction
system. In areas where road salt is used, the inspection consists of
disassembling the joints of each aluminum component and inspecting for
salt build-up, 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 the intake pipes are pitted at the joint ends, use MotorcraftSilicone
Gasket and Sealant TA-30 to seal the joints. Be certain that no excess
material is on the inside of the pipes that can be pulled into the engine.
If the service condition of the pipes, hoses or clamps is questionable,
replace the defective part(s).
Be sure that prior to reassembly all dust and debris has been cleaned out
of the pipes and couplings with a clean, damp rag.
WARNING:When performing maintenance to any turbocharged
engine with engine air inlet piping disconnected, keep loose
clothing, jewelry and long hair away from the engine air inlet piping. A
turbocharger compressor air inlet protective shield should be installed
over the turbocharger air inlet to reduce the risk of personal injury or
death.
Steering - general inspection
•Ask your service technician to examine the steering mechanism. Only
minor adjustments may be necessary.
•Check tie rod, drag link end clamp bolts and ball joints. They must be
tight.
•Check for installation and spread of cotter pins and tightness of nuts
at both ends of the tie rod and drag link.
•Check that pitman arm (steering arm at steering gear) mounting is
tight and locked. Check system for leaks or hose chafing. Repair at
once.
•Maintain proper steering gear and power steering pump lubricant
levels.

•Regularly inspect steering column joint bolts and steering linkage,
particularly for body-to-chassis clearance.
Note:Have any steering problems corrected at once by a qualified
service technician.
WARNING:Failure to maintain the steering system in proper
condition can cause reduced steering ability resulting in property
damage, personal injury or death.
Tightening steering column joint bolts
As a good maintenance practice, it is recommended that steering column
joint bolts be checked for tightness every 60,000 miles (96,000 km) or
annually, whichever occurs first. DO NOT OVERTIGHTEN.
Power steering hydraulic system
Whenever the power steering’s hydraulic system has been drained and
refilled for any reason, air must be bled from the system before returning
the vehicle to service. Failure to properly bleed the hydraulic system can
result in degradation of power system performance.
Consult your dealer who is aware of the proper procedures for filling and
bleeding the system.
OPENING THE HOOD
The hood and fenders are held in position by a latch located on each
fender.
WARNING:The parking brake must be fully set before opening
the hood or possible personal injury may occur.
WARNING:To reduce the risk of the possibility of personal
injury, never stand beneath the hood when it is being raised or
lowered.
WARNING:If you must leave the engine running while checking
under the hood, do not allow any loose clothing, jewelry, hair or
other items to get near moving engine components or possible personal
injury may occur.

1. Bring the vehicle to a complete stop on level ground and safely off the
road with the exhaust system away from people, flammable materials,
vapors or structures. Ford recommends that you perform a walk-around
to check before commencing parked regeneration.
2. If your vehicle is equipped with an automatic transmission and a
steering column shift lever, place transmission in P (Park). Otherwise,
place the transmission in N (Neutral).
3. Remove feet from the accelerator pedal and clutch pedal (if
equipped).
4. Set the parking brake.
5.Within 5 seconds of setting the parking brake,remove foot from
the service brake pedal.
The engine speed may increase slightly. To allow parked regeneration to
continue uninterrupted:
1. The vehicle must remain parked
2. The transmission must remain in P (Park) or N (Neutral) (as
previously described in Step 2).
3. The accelerator pedal, service brake pedal, and clutch pedal (if
equipped) must not be pressed
4. The parking brake must remain set
On average (depending on filter level and other factors), the process will
take 20–30 minutes to complete. The DPF lamp will turn off when the
process is complete. Repeat Steps 1–5, if parked regeneration is
interrupted.
To discontinue parked regeneration
Press any of the floor pedals to discontinue parked regeneration.
Diesel particulate filter maintenance and service
The DPF is designed to retain a relatively large amount of residual ash
and provide many miles and hours of maintenance-free operation. At
some point, generally beyond 150,000 miles (240,000 km) or 5,000 hours
of operation (whichever comes first), the DPF will require professional
cleaning to remove the accumulated ash
The exact number of miles or hours of operation will vary greatly
depending upon vehicle/engine loading and operating conditions, ash
content of the engine oil, and quality of the diesel fuel used in your
truck. Adhering to your engine manufacturer’s recommended oil and fuel

recommended parts. Inspect for fan to shroud interference, and any
damage to shroud such as cracks and holes.
•The fan ratio should not be changed and the fan spacer dimensions
and positions should not be altered.
•Inspect the fan clutch for proper operation, make sure that the fan is
disengaged when cooling of the engine is not required.
•Check for proper operation of radiator shutters, if equipped. The
shutters should be open during normal operating temperatures.
Engine and Driveline System
•Transmission Enclosure:inspect for cracks, holes, and tears. Clean
any deposits such as oil, dirt, and stones.
•Engine valve covers and block covers are made to damp out engine
mechanical noise and, if needed, should be replaced with
recommended parts. Check for mechanical isolations.

4. Remove the dipstick from the reservoir and wipe the dipstick clean.
5. Reinstall the dipstick. Remove it again and check the fluid level.
•If the fluid temperature is at
approximately 68°-120°F
(20°-49°C) (fluid cool or warm
to the touch), check the COLD
side of the dipstick. The fluid
level should be within the FULL
range
•If the fluid level is below the ADD
line, add fluid in small amounts, continuously checking the level until
it reaches the proper level.
•If the fluid temperature is at
approximately 176°–230°F
(80°-110°C) (fluid too hot to
touch), check the HOT side of
the dipstick. The fluid level
should be within the FULL range.
•If the fluid level is below the ADD
line, add fluid in small amounts,
continuously checking the level until it reaches the proper level.
Note:The fluid level may also be checked by looking at the see-through
plastic reservoir. Make sure that the fluid is within the minimum and
maximum fluid range as marked on the reservoir.
A low fluid level may indicate a leak in the power steering system.
Inspect the power steering system and repair the leak. If necessary, see
your dealer or a qualified service technician.
To avoid damage to the power steering system,do notoperate the
vehicle with a low power steering fluid level.
Whenever the dipstick is installed, make sure it is properly seated and
tightened securely.

Under-inflation is the primary cause of premature tire concerns including
sudden loss of air. In addition, low inflation causes an increase in rolling
resistance. This results in reduced fuel mileage, a loss in tread mileage,
and uneven wear due to increased tread movement. To determine proper
inflation refer to the tire manufacturer load/inflation guide which can be
found on the tire manufacturer website or at your local truck tire dealer.
Inspection
Check condition of tires for abnormal wear patterns, and proper inflation
pressures. Cut or broken tire casing must be repaired or replaced.
Tires should be inspected for the following conditions. If any are present,
the tire should be removed and repaired, retreaded or scrapped as the
condition indicates.
•Any blister, bump or raised portion anywhere on the surface of the
tire tread or sidewall (other than a bump made by a repair). These
indicate the start of internal separation.
•Any cut that reaches to the belt or ply cords, or any cut that is large
enough to grow in size and depth.
•Any nail or puncturing object.
•If any stone or object is held by a tread groove and is starting to drill
into the tread base, remove the object.
Proper tire inflation, toe-in adjustment, loads, and road speeds are
important factors governing tire mileage, steering ease and
maneuverability.
Loads
WARNING:Loading tires beyond their rated capacity decreases
tire life requiring more frequent replacement of tires.
Overloading creates an unsafe condition that may result in sudden air
loss from a tire failure resulting in an accident that could cause
property damage, personal injury or death.
Note:Your GAW/GVW rating is correct at the time of your vehicle
production, and reflects the exact rating of the tires specified. When
replacing tires be sure that the replacement tire load rating (listed in
pounds and kilograms on the tire sidewall) is the same or higher than
the tire that is removed. Failure to do so will adversely affect maximum
load carrying capacity. Tires with the same size specification do not
always have the same load specification.

Matching
Dual Tires:Dual tires should be matched using tires of equivalent size.
Tires which differ more than
14inch (6 mm) in diameter or34inch
(19 mm) in circumference should not be mounted on the same dual
wheel assembly.
Mixing:Never mix bias and radial tires on this vehicle. Never mix
different tire sizes or constructions on the same axle.
Rotation:
Rotation is always advisable:
1. If front (steering) axle tires become irregularly worn, move to rear
position.
2. In a dual assembly, reverse the position of the tires if one tire wears
much faster than its mate.
3. On the drive axle, if heel and toe wear or alternate lug wear occurs,
rotating the tires from one end of the axle to the other end of the axle
may help even out this wear.
Rotation may not advisable:
1.Front (Steering) Axle:Tires must be removed when tread is worn
to 4/32 inch (3 mm) or less. Retread or rotate worn tires to drive
position. Retreaded tires are not recommended to be used on steering
axles.
2.Rear Axles:Tires must be removed when tread is worn to 2/32 inch
(2 mm).
If rib tire is used on front axle and lug or off-road type on rear axle
positions:
1.Front (Steering) Axle:Replace tires at front wheels when tread is
worn to 4/32 inch (3 mm) or less.
2.Rear Axles:Tires must be removed when the tread is worn to
2/32 inch (2 mm) or less. Tires identified with the word “re-groovable”
molded on the sidewall can be re-grooved. A minimum of 3/32 inch
(2.5 mm) of under-tread must be left at the bottom of the grooves.
Wheel and tire balancing
Out-of-round or out-of-balance wheels or tires can cause vehicle
vibration, bounce and shimmy. Replace damaged or out-of-round wheels.
Out-of-round tires and wheel assemblies can be corrected by re-clocking
the tire relative to the wheel.
The tire and wheel assembly should then be dynamically balanced.
