CLUTCH FLUID/LINKAGE ADJUSTMENTS
Clutch fluid (if equipped)
During normal operation, the fluid level in the clutch reservoir should
remain constant. If the fluid level drops, fill to step in the reservoir.
1. Set the parking brake, shift into 1
(First) and turn the engine off.
2. Open the hood.
3. Clean the reservoir cap before
removal to prevent dirt and water
from entering the reservoir.
4. Remove cap and rubber
diaphragm from reservoir.
5. Add fluid, if necessary, until it
reaches the step in the reservoir.
6. Reinstall rubber diaphragm and cap onto reservoir.
Use only a DOT 3 brake fluid designed to meet manufacturer
specifications. Refer toLubricant specificationsin this chapter.
WARNING:Carefully read cautionary information on product
label. For MEDICAL EMERGENCY INFORMATION, contact a
physician or Poison Control Center immediately; on Ford-Motorcraft
products call: 1-800-959-3673 (FORD). Failure to follow these
instructions may result in personal injury.
Refer to theScheduled Maintenance Guidechapter for service interval
schedules.
Clutch linkage (if equipped)
Lubricate the clutch linkage using the following procedure. Use a grease
which meets manufacturer specifications. Refer toLubricant
specificationsin this chapter.
1. Set the parking brake, shift into 1 (First) and turn the engine off.
2. Remove the inspection cover from the clutch housing.

3. Lubricate the clutch release bearing (at one location) and the clutch
release shaft (at two locations), using the grease fittings provided, with a
grease gun.
4. Lubricate clutch release wear pads at the two locations where they
contact the clutch release bearing with a brush or similar tool.
5. Install the inspection cover onto the clutch housing.
Refer to theScheduled Maintenance Guidechapter for the service
interval schedules.
TRANSMISSION FLUID
Automatic transmission fluid
Refer to yourAllison Automatic Transmission Operator’s Manualfor
scheduled transmission fluid check/change intervals. Your transmission
does not consume fluid. However, the fluid level should be checked if the
transmission is not working properly, i.e., if the transmission slips or
shifts slowly or if you notice some sign of fluid leakage.
Automatic transmission fluid expands when warmed. To obtain an
accurate fluid check, drive the vehicle until it is warmed up
(approximately 20 miles [30 km]). If your vehicle has been operated for
an extended period at high speeds, in city traffic or during hot weather,
the vehicle should be turned off for about 30 minutes to allow fluid to
cool before checking.
1. Drive the vehicle 20 miles (30 km) or until it reaches normal operating
temperature.
2. Park the vehicle on a level surface and engage the parking brake.
3. With the parking brake engaged and your foot on the brake pedal,
start the engine and move the gearshift lever through all of the gear
ranges. Allow sufficient time for each gear to engage.

4. Place the gearshift lever in N (Neutral) or P (Park) and leave the
engine running.
5. Remove the dipstick, wiping it clean with a clean, dry, lint-free rag.
6. Install the dipstick, making sure it is fully seated in the filler tube.
7. Remove the dipstick and inspect the fluid level.
If you must add transmission fluid, refer to yourAllison Automatic
Transmission Operator’s Manualfor the correct fluid type.Use of a
non-approved automatic transmission fluid may cause internal
transmission component damage.
Fluid levels above the safe range may result in transmission failure; an
overfill condition of transmission fluid may cause shift and/or
engagement concerns and/or possible damage.
Eaton UltraShift (if equipped)
The Eaton UltraShift transmission is filled with synthetic fluid from the
factory with no scheduled fluid change intervals as this fluid is intended
to last the life of the transmission. However, the system should be
checked regularly to ensure that proper transmission fluid levels remain
constant. Refer to theEaton Driver Instructions Manualfor details.
Manual transmission fluid
Refer to theScheduled Maintenance Guidechapter for transmission
fluid level check/change intervals.
Your manual transmission may be filled with an optional synthetic fluid
which allows the use of extended service intervals. A tag on the filler
plug identifies the use of the synthetic fluid.
Only use fluid that meets manufacturer specifications; refer toLubricant
specificationsin this chapter.Use of a non-approved transmission
fluid may cause internal transmission component damage.
Check your transmission fluid level using the following procedure:
1. Park the vehicle on level ground.
2. Set the parking brake and shift into 1 (First) and turn the engine off.
3. Clean any dirt from around the filler plug.
4. Remove the filler plug and inspect the fluid level; the fluid level should
be at the bottom of the filler plug opening.
5. Add fluid, if necessary, through the filler plug opening.
6. Clean and install the filler plug securely.

Drain and refill your transmission fluid, while it is warm, using the
following procedure:
1. Park the vehicle on level ground.
2. Set the parking brake and shift into 1 (First) and turn the engine off.
3. Clean any dirt from around the filler and drain plugs.
4. Remove the filler and drain plugs and drain the fluid into a suitable
container. Dispose all used automotive fluids in a responsible manner
following your local authorized standards.
5. Clean and install the drain plug securely.
6. Add fluid through the filler plug opening.
7. Clean and install the filler plug securely.
CHASSIS-MOUNTED CHARGE AIR COOLER
Inspect charge air cooler daily
Visually inspect the core assembly for debris and clogging of external fins
with the engine off. Prior to 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 the
intake piping is pitted, use MotorcraftSilicone 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.

ELECTRICAL SYSTEM INSPECTIONS
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 MotorcraftSilicone 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 5 volts. Refer to the
Electrical Circuit Diagram Manuals, available from your vehicle’s
manufacturer, to ensure 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.
SUSPENSION 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; this must be maintained at all times.
•U-bolts after the chassis has been operating under load for 1,000 miles
(1,600 km) or six months (whichever comes first), the U-bolt nuts
must be re-torqued. The U-bolt nuts must be re-torqued every
36,000 miles (58,000 km) thereafter. The U-bolt and nut threads and
seats should be cleaned and lubricated to ensure a “like new”
condition when re-torquing.
Note:See theU-bolt nut torquechart later in this section.

WHEELS
General
Wheel bearings should be inspected, lubricated and adjusted at regular
intervals. This is especially important if operating in deep sand, mud or
water. Refer toLubricant specificationsin this chapter.
Mount wheel balance weights on the dome-side of the wheel only; failure
to do so may result in loss of wheel weight and/or damage to brakes or
wheels.
Important:Remember to replace the wheel air valves when the road
tires are replaced at the end of their useful life.
