SCHEDULED MAINTENANCE SERVICES
Maintenance service adjustments must conform to specifications
contained in this manual, and those shown on the Important Engine
Information Decal. The following services are to be performed at
scheduled intervals because they are considered essential to the life and
performance of your vehicle. Ford recommends that you perform
maintenance on all designated items to achieve best vehicle operation.
Scheduled maintenance beyond 160 930 km (100 000 miles) should be
continued as before 160 930 km (100 000 miles).
SPECIAL OPERATING CONDITIONS
If your driving habitsfrequentlyinclude one or more the following
conditions:
•Short trips oflessthan 16 km (ten miles) when outside temperatures
remain below freezing.
•Operating duringhot weatherin stop-and-go“rush hour”traffic.
•Operating in severe dust conditions.
•Extensive idling, or low speed operation such as door-to-door delivery
service.
•High speed operation with a fully loaded vehicle (max. GVW).
•Snowplowing.
Perform the following:
•Change engine oil and oil filter every three months, 8 000 km (5 000
miles) or 125 hours of engine service.
•If operating in severe dust conditions, replace the air cleaner filter
more often than regular intervals as determined by the air filter
restriction indicator. Make sure that the air filter restriction indicator
is in good working order.
•Lube the manual transmission and the rear axle every 48 279 km
(30 000 miles) or 6 months, whichever comes first.
•See the Allison, Cummins and Caterpillar Operator’s Manual.
AIR BRAKE ADJUSTMENT
Failure to maintain proper air brake adjustment can result in
reduction or loss of braking ability.
Air brake inspection and adjustment should be performed by a qualified
service technician in accordance with the instructions in the Ford Truck
Service Manual.
General Maintenance Information
229

Cam brakes - automatic slack adjusters
Inspect standard air brakes equipped with automatic slack adjusters for
proper brake adjustment every four months or 32 000 km (20 000 miles)
whichever occurs first.
However, more frequent inspection is required if your vehicle’s brakes
are subjected to heavy use or adverse operating conditions such as:
•Frequent brake applications while fully loaded.
•Operation on hilly or mountainous terrain.
•Frequent operation on dirt, gravel or mud.
Some aftermarket brake linings also require more frequent inspections.
