CHASSIS
C - 1
The Airstream motorhome is built on a Freightliner chassis. Operation of the engine
and other related components are discussed in the Freightliner Owners and Drivers
Manual supplied with each coach.
If repairs are needed it can be difficult to determine which parts of the chassis are
warranted by Freightliner, and which are Airstream’s responsibility. The following
list shows the major components of the chassis and the company responsible for
their servicing.

The above list covers almost all of the chassis components. If you need further clarifi-
cation or information your dealer should be contacted with the details.
ENGINE ACCESS
Although most engine functions and maintenance can be preformed from outside the
coach, occasionally “top” engine service will be required.
To make this servicing easier the bed top can be raised with the assistance of gas
props. Once the bed top is raised the engine cover can be unlatched and raised to
expose the engine.
WARNING : The lifting and supporting strength of the gas props vary
according to temperature. Props that support the bed top when hot may let the
bed close rapidly when cold.
AIR BRAKE SYSTEM DRAINAGE
Your motorhome is equipped with an air brake system. When air is compressed some
liquid is forced out and collects in the bottom of the air ranks and must be drained.
Three drain valves are on your brake system. The valves can be opened for drain-
age by pulling on the looped cables in your front wheel wells on each side. See your
Freightliner operator’s manual under Pre-trip Inspection for directions.
REFUELNG
For your conveinence refueling access is located on both sides of the motorhome.
The placement of the fuel tank dual necks and pipes and/or a slightly unlevel vehicle
will prevent the fuel tank from being filled to the stated capacity. The fuel guage will
indicate between 3/4 and 7/8 full when no mare can be added. This a normal condition.
For calculating the distance between fueling stops, use 120 gallons fro calculations.
Please read and follow all refueling cautions and warnings in your chassis manual.
