SECTION 1 INTRODUCTION
SCOPE
This manual was created to provide body builders with
appropriate information and guidelines useful in the
body planning and installation process. This information
will be helpful when installing bodies or other associated equipment.
This manual contains appropriate dime nsional information, guidelines for mounting bodies, guidelines for
modifying frames, electrical wiring information, and
other information useful in the body installation process.
The intended primary users of this manual are body
builders who install bodies and associated equipment
on Kenworth T300 Medium Duty vehicles. Dealers who
sell and service the vehicle will also find this information
useful.
This Body Builders’ Manual can be very useful when
specifying a vehicle, particularly when th e body builder
is involved in the vehicle definition and ordering pro-
cess. Early in the process, professional body builders
can often contribute valuable information that reduces
the ultimate cost of the body installation.
This manual is not a maintenance manual or an
operation manual.

FEDERAL MOT OR VEHICLE SAFETY STANDARDS (FMVSS) COMPLIANCE
As an Original Equipment Manufacturer (OEM), Kenworth Truck Co. ensures that our products comply with
all applicable Federal Motor Vehicle Safety Standards
(FMVSS). However, the fact that this vehicle has no
fifth–wheel and that a Body Builder (Final Stage M anufacturer) will be doing additional modifications means
that the vehicle was incomplete when it left the build
plant. See page 2–2

“VEHICLE IDENTIFICATION.”
NOTE: These documents list the FMVSS regulations that the vehicle complied with when it
left the build plant. You should be aware that if
you modify or alter any of the components or
systems covered by these FMVSS regulations, it is your responsibility as the Final
Stage Manufacturer to ensure that the complete vehicle maintains compliance with the
particular FMVSS regulations whe n you complete your modifications.

As the Final Stage Manufacturer, you should retain the
Incomplete Vehicle Document for your records. In addition, you should record and retain the manufacturer and
serial number of the tires on the vehicle. Upon completion of the vehicle (installation of the body and any other
modifications), you should affix your certification label
to the vehicle as required by Federal law. This tag identifies you as the “Final Stage Manufacturer” and certifies that the vehicle complies with Federal Motor
Vehicle Safety Standards. (See Figure 2–2.
