service manuals
for further
instructions and

Check the engine cooling system - hoses, clamps and protection
Inspect the drive belts
Exhaust system
Inspect the entire exhaust system (including the inlet pipe(s),
muffler(s), outlet pipe(s), clamps and fasteners) for holes,
leakage, breakage, corrosive damage and separation from other
components. Adjust, service or replace with the same or the
equivalent part. (Also a noise emission control service)
Suspension system
Tighten the front and rear spring U-bolts to the specified torque
Driveline and rear axle system
Lubricate the U-joints and the slip yoke
Brake system
Lube the air brake foot control valve, hinge and roller
Inspect the drum brake linings through the inspection holes
Lubricate the brake camshafts (air brakes)
Lubricate the brake slack adjuster (air brakes)
Lubricate rear caliper slide rails
Inspect the disc brake pads and the piston boots (hydraulic
brakes)
Clutch system
Lubricate the clutch release cross shaft and all linkages
Check the clutch fluid
Fuel system
Drain the accumulated water or sediment from the fuel tank(s)
Steering system
Lubricate the steering shaft(s), U-joints and splines when
equipped with grease fittings
Lubricate the front axle spindle pins
Lubricate the steering linkage when equipped with grease
fittings
Grease the power steering gear output shaft
* Coolant protection checks should be made just prior to the onset of freezing
weather, where applicable. If coolant is dirty or rusty in appearance, the system
should be drained, flushed and refilled with the prescribed solution of cooling
system fluid and water. Use only permanent type coolant that meets Ford
specifications WSS-M97B51-A1. See the engine manufacturer’s operating guide for
supplemental corrosion inhibitor specifications.

Maintenance Operation Frequency - Observation
Inspect the automatic slack
adjuster functionInsufficient power shown in loaded
practice stop
Check the operation of the
brakes, the clutch, and the
steering (A, B)Vehicle handling qualities not up to
par
Inspect the vehicle for missing,
damaged, or mislocated noise
shieldsExcessive noise emanates from under
the cab or engine compartment
Check the engine performance
and the engine governorExcessive engine noise
Inspect the fan, the fan shroud,
and the fan clutchEngine overheats, fans runs at high
speed constantly, excessive fan noise,
or fan wobble due to worn bearings
Check for operation of ABS
warning lampAt each engine start up
Inspect the entire exhaust
system (including inlet pipe,
muffler, outlet pipe and all
exhaust clamps and fasteners)
for holes, leakage, breakage,
looseness and corrosive
damageExcessive noise or the smell of fumes
is experienced
Inspect the engine air
induction system (including the
air ducts, the air cleaner, and
the air cleaner element) for
loose fitting, damaged or
missing componentsExcessive noise emanates from the
engine compartment
Inspect the tires and check the
air pressure (C)Poor steering, wandering or excessive
tire wear
Balance the wheels and the
tiresVibration or abnormal tire wear
indicates imbalance
Check the front end alignment
(C)Poor steering, wandering or excessive
tire wear

Maintenance Operation Frequency - Observation
Check the transmission and
engine mountings (B)Hard shifting or excessive vibration
Check and adjust transmission
controls (B)High effort to shift or noisy
transmission
Check fuel pump pressure Insufficient full-throttle power or
backfiring
Clean radiator cap seal. Clean
and inspect the cap surface on
the radiatorWhen the cap does not hold pressure
Check the battery terminals for
corrosionWhenever electrical power supply has
diminished
Tighten the wheel mounting
nuts to the specified torque.
Refer toServicing your
wheels and tiresRequired initially at 500 and 1000
miles (800 and 1600 km). Perform
again at 500 and 1000 mile (800 and
1600 km) intervals after each tire
removal/replacement.
A - During maintenance and repair, protect the fuel tube and the hose
assemblies, the power steering lines, and the brake lines from the
external heat, the acids and the abrasion that could damage the lines.
B - Check for (free) linkage action and ensure that (return) spring
force is adequate to maintain pedal free play.
C - Adjust, repair or replace as required with the same or equivalent
parts.
