Changing wheel types
Consult your dealer or wheel/rim distributor before attempting any wheel
or fastener changes.
Use only the same type and style wheels and mounting hardware
to replace original parts. Failure to do so may result in an
assembly that looks fine, but does not fit together properly. This could
possibly cause wheel or fastener failures which could result in property
damage, personal injury or death.
Do not attempt to mix stud-piloted wheels or fasteners with
hub-piloted wheels or fasteners.
Do not change from aluminum wheels to steel wheels or
vice-versa without changing the mounting hardware required or,
with flange-nut mounting systems, changing the hub and stud
assembly.

Note:Do not use lubrication on dry threads. Where excessive corrosion
exists, a light coat of lubricant on the first three threads of the stud bolt
is permitted. Keep lubricant away from:
•Hex nut and rim clamp contact surfaces.
•Cap nut ball face and ball seat on the disc wheel.
•Flange nut washer surface and flat on the disc wheel.

LUBRICATION AND MAINTENANCE INTERVALS
New vehicles are lubricated at the factory. After the vehicle is placed in
operation, regular lubrication intervals, based on the type of service and
road conditions, should be established. Thorough lubrication at the
specified intervals will insure outstanding life cycle value and will reduce
overall expense.
The lubrication intervals specified should be performed at whatever
interval occurs first, whether it is months, kilometer (miles) or hours.
Only lubricants of superior quality, such as Motorcraft lubricants, should
be used. The use of inferior products will reduce the service life of the
vehicle or result in failure of its components.
Unless otherwise specified, never add lubricant unless it is the same
grade as that which is already being used. If the grade is not known or
not available, drain, flush and refill with new lubricant.
The interval between lubrication periods, oil changes, etc. depends
entirely upon operating conditions. The loads carried, speeds, road and
weather conditions all contribute to the frequency of lubrication periods.
In some types of operation, and where operating conditions are
extremely severe (such as in deep water, mud or unusually dusty
conditions), the vehicle may require lubrication after every 24 hours of
operation.
Maintenance intervals
Maintenance intervals are provided for three types of general vehicle
environments: On-Highway, City and Severe Service. In all applications,
the actual interval is determined by monitoring kilometers (miles) and
time and when the engine is due for an oil change. When the engine oil
change is required prior to the truck lubrication interval, it is
recommended that the lubrication be performed at the same time in
order to reduce your vehicle’s time out of service.
•On-Highway:96,000 km (60,000 miles) or more annually.
•City:95,000 km (59,000 miles) or less annually.
•Severe Service:32,000 km (20,000 miles) or less annually on/off
road in dirty conditions.
