PREVENTIVE MAINTENANCE AIR SYSTEM
Regional Haul
(R05/10) Y53-6033 – 197 –
High Frequency Vibration: Vibration may indicate turbo
rotor imbalance. Have your Peterbilt Dealer or Authorized
Service Center investigate this immediately. If you detect
any deficiencies, take the vehicle to an Authorized Ser-
vice Center for servicing. Delay could lead to severe and
expensive damage to your vehicle.
Air Filter Replacement
Service the filter elements when the Air Cleaner Restric-
tion gauge (option) locks in the extreme High position.
Have the element serviced at a Peterbilt Dealer or Autho-
rized Service Center. Paper elements require care and
proper handling, because they are critical to engine ser-
vice life.
Service the air cleaner periodically. If the vehicle operates
in areas with heavy dust, maintenance should be more
frequent. Follow the instructions below to remove the air
filter.
To remove the air filter:
1. Remove the two thumb screws.
2. Remove air cleaner service cover.
3. Remove the filter element.
Clean out the inside of the air cleaner body and outlet tube
with a dry rag.
