PREVENTIVE MAINTENANCE
AIR SYSTEM
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 Service
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 Restriction
gauge (option) locks in the extreme High position.
Have the element serviced at a Peterbilt Dealer or Authorized
Service Center. Paper elements require care and
proper handling, because they are critical to engine service
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.
