2017 FORD F750 wheel bolts

Front brakes
Inspect for cracked, worn or frayed hoses, and that all coup-
lings are secure.
Hoses
Verify that there are no cracks or dents, and that the cham-
bers are securely mounted.
Brake chambers
Inspect for broken, loose or missing parts.
Slack adjusters
Note: The angle between the push rod and adjuster arm
should be approximately 90 degrees when the brakes are
applied. When pulled by hand, the push rod should not move
more than approximately
1 in (2.5 cm).
Verify that there are no cracks, dents, holes, and no loose or
missing bolts and that the brake linings are not worn,
dangerously thin or contaminated by lubricant.
Drums Front wheels
Inspect for damaged or bent rims. They should not have
welding repairs, and there should be no rust trails, which
indicate it is loose on the wheel.
Rims
Verify all lug nuts are present and not loose (look for rust
trails around the lug nuts). There should be no cracks radiating
from the lug bolt holes or distortion of the bolt holes.
Lug nuts
Inspect wheel hub oil seal for leaks and, if sight glass if
present, verify the oil level is adequate.
Hub oil seals
Inspect for proper lubrication level if the hubcap has a trans-
parent window. If the hubcap does not have a transparent
window, remove the rubber fill-plug and inspect for proper
level.
Oil-lubricated front
wheel bearings Fuel area
Verify the tank(s) and cap(s) are secure and that there are
no leaks from the tank(s).
Fuel tank(s)
Inspect for leaks from the tank(s).

missing or loose bolts; missing or damaged bushings; broken,
loose or missing axle mounting parts.
Spring mounts (if
equipped)

Torsion arm and shock
absorbers
Inspect the shock absorber for cracks or leaks. There should
be no missing or broken mounting bolts or worn bushings.
Inspect for missing, broken or leaking components.
Air suspension (if
equipped) Inspect for any cracked, broken or loose bolts; missing or
damaged bushings; broken, loose or missing axle mounting
parts.

Rear brakes
Inspect for cracked, worn or frayed hoses, and that all coup-
lings are secure.
Hoses
Verify that there are no cracks or dents, and that the cham-
bers are securely mounted.
Brake chambers
Inspect for broken, loose or missing parts.
Slack adjusters
Note: The angle between the push rod and adjuster arm
should be approximately 90 degrees when the brakes are
applied. When pulled by hand, the push rod should not move
more than approximately
1 in (2.5 cm).
Verify that there are no cracks, dents, holes, and no loose or
missing bolts and that the brake linings are not worn,
dangerously thin or contaminated by lubricant.
Drums Rear wheels
Check for even separation of dual wheels, and that the tires
are not touching each other.
Spacers
Inspect for damaged or bent rims. They should not have
welding repairs, and there should be no rust trails, which
indicate it is loose on the wheel.
Rims
Verify all lug nuts are present and not loose (look for rust
trails around the lug nuts). There should be no cracks radiating
from the lug bolt holes or distortion of the bolt holes.
Lug nuts
Trailer
If you are pulling a trailer, perform an
inspection of the trailer similar to that of
the tractor. The inspection should follow
trailer manufacturer recommendations
and should include at a minimum: general
condition, landing gear, doors, sides, lights,
reflectors, suspension, brakes, tires,
wheels, cargo placement, stability and
tie-downs. Transmission WARNING
If the unit starts in gear and/or the
neutral start switch is not functioning
correctly, the vehicle may
inadvertently move which could result in
property damage, personal injury or death. Regularly inspect the transmission's
neutral start switch. The engine should
only start in neutral (N) or park (P) (if
equipped with a park position).

1. Clean the filter cover and remove the bolts.
2. Carefully remove the filter cover.
3. Remove used filter element from the filter housing and carefully dispose of
it.
4. Make sure that the sealing surfaces on
the filter housing and cover are clean
and free of debris.
5. Install the new filter element.
6. Install the filter cover.
7. Install the bolts finger-tight. 8.
Fully tighten all of the bolts to between
3–4 lb.ft (4.5–6 Nm) in the sequence
shown.
9. Record the engine mileage and update
the service log accordingly.
OIL CHANGE INDICATOR
RESET
Use the information display controls on
the steering wheel to reset the oil change
indicator. See
General Information
(page 62).
ENGINE COOLANT CHECK -
6.8L WARNINGS
Do not add engine coolant when the
engine is hot. Steam and scalding
liquids released from a hot cooling
system can burn you badly. Also, spilling
coolant on hot engine parts can burn you. Do not put engine coolant in the
windshield washer fluid container. If
sprayed on the windshield, engine
coolant could make it difficult to see
through the windshield.

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.
