BODY

GENERAL INFORMATION

The body of the vehicle is constructed of aluminum and fiberglass. Extruded aluminum ribs and struts are welded together to form a cage-like framework.

The exterior skin is than bonded directly to the framework (See Figure 38).

Figure 37-Cab Roof Insulation

Both front and rear end caps are fiberglass; and the lower side panels, below the belt line, are fiberglass. The side panels, above the belt line, are sheet aluminum. The main roof panel is also sheet aluminum. The roof and side panels are bonded directly to the aluminum framing. Pop rivets are then used to secure the panels where the roof and side panels are joined . Rivets are also used at the belt line.

INSULATION

The main body area, rear end cap, side panels, and roof cap of the driver's compartment are coated with 3/4" thick rigid urethane foam, (figure 37). Areas which must remain accessible for servicing have not been coated with insulation. These areas include electrical harnesses, structure flanges, interior component mounting surfaces, and pre-insulated areas.

CAUTION: Urethane foam is a flammable material. Welding near insulation may result in damage to insulation and/or vehicle.

As previously discussed, polyurethane foam panels insulate the floor area. The driver toe pan mat is insulated with 1/4" of "ENSOLITE". The lower dash area is also insulated. The insulation package applied to vehicle insures temperature control and improves performance of heating and air conditioning systems. Be careful not to damage insulation when making repairs.
