A Special Word About Repairs
This is not a repair or workshop manual. Your Peterbilt
Dealer's Service Center is the best place to have your
Medium Duty repaired. You can find Peterbilt dealers all
over the country with the equipment and trained person-
nel to quickly get you back on the road—and to keep you
there.
Your Medium Duty is a complex machine. Anyone
attempting repairs on it needs good mechanical training,
proper specifications, and proper tools. If you are sure you
meet these qualifications, then you can probably perform
some repairs yourself. But if you are not an experienced
mechanic, or do not have the right equipment or training,
please leave the repairs to an authorized service facility.
They are the ones equipped to do the job safely and cor-
rectly.
WARNING! Do not attempt repair work without
sufficient training, service manuals, and the
proper tools. You could be injured, or you
could make your vehicle unsafe. Do only
those tasks you are fully qualified to do.
