Introduction
This manual provides body builders with appropriate information and guidelines useful in the body planning and in-
stallation process. This information will be helpful when installing bodies or other associated equipment.
This manual contains appropriate dimensional 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
K270/K370 Medium Duty vehicles. Dealers who sell and service the vehicle will also find this information useful.
This Body Builder’s Manual can be very useful when specifying a vehicle, particularly when the body builder is in-
volved in the vehicle definition and ordering process. Early in the process, professional body builders can often con-
tribute valuable information that reduces the ultimate cost of the body installation.
This manual is not a maintenance manual or an operation manual.
• For chassis maintenance and repair information consult the PACCAR ServiceNet available in the Service De-
partment of the selling dealer or order a custom shop manual or parts catalog for your vehicle through your local
dealer.
• For chassis operating information consult the Operator’s Manual, included with each vehicle. It can also be or-
dered from your local dealer.

Safety & Compliance
SAFETY SIGNALS
We have put a number of alerting messages in this book. Please read and follow them. They are there for your protection and infor-
mation. These alerting messages can help you avoid injury to yourself or others and help prevent costly damage to the vehicle
.
Key
symbols and “signal words” are used to indicate what kind of message is going to follow. Pay special attention to
comments prefaced by “WARNING”, “CAUTION”, and “NO TE . ” Please do not ignore any of these aler ts .
Warnings,Cautions, and Notes
WARNING:
When you
see this word and symbol, the message that f ollo ws is especially vital. It signals
a potentially hazardous situation which, if not avoided, could result in death or serious
injury.
This message will tell you what the hazard is, what can happen if you don’t heed the
w
ar ning, and how to avoid it.
Example:
WARNING! Be sure to use a circuit breaker designed to meet liftgate amperage requirements. An in-
correctlyspecified
circuit breaker could result in an electrical overload or fire situation. Follow the
liftgate installation instructions and use a circuit breaker with the recommended capacity .
CAUTION:
Signals a potentially hazardous situation which, if not avoided, could result in minor
or moderate injury or damage to the v ehicle .
Example:
CAUTION: Never use a torch to make a hole in the rail. Use the appropriate drill bit.
NOTE:
Provides general information. F or example, the note could warn you on how to avoid damaging your vehicle or how to
drive the vehicle more efficiently
.
Example:
Note: Be sure to provide maintenanceaccess to the battery box and fuel tank fill nec k.
Please take the time to read these messag es when you see them, and remember:
WARNING
Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.
CAUTION
Signals a potentially hazardous situation which, if not avoided, could result in minor or moder ate
injury or damage to the v ehicle .
NOTE
Useful information that is related to the topic being discussed.

Safety & Compliance
FEDERAL MOTOR VEHICLE SAFETY
STANDARDS COMPLIANCE
As an Original
Equipment Manufacturer (OEM), Kenworth Truck Co. ensures that our products comply with all applicab le
U.S. or Canadian Federal Motor Vehicle Safety Standards. However, the f act that this vehicle has no fifth wheel and that a
Body Builder (Intermediate or Final Stage Manufacturer) will be doing additional modifications means that the vehicle w as
incomplete when it left the build plant. See next section and Appendix A for additional inf or mation.
Incomplete Vehicle Cer tification
An Incomplete Vehicle Document is shipped with the vehicle, certifying that the vehicle is not complete. See Figure 2–1.
In addition, affixed to the driver’s side door frame or edge is an Incomplete Vehicle Certification label. See Figure 2–2. For further in-
formation on Vehicle Certification and Identification, see APPENDIX A “VEHICLE IDENTIFICATION” or owner’s manual.
NOTE:
These documents list the U.S. or Canadian Federal Motor Vehicle Safety Standard regulations that the
vehicle complied with when it left the build plant. You should be aware that if you add, modify or alter
an y of the components or systems covered by these regulations, it is your responsibilityas the Inter-
mediate or Final Stage Manufacturer to ensure that the complete vehicle is in compliance with the
par ticular regulations upon completion of the modifications .

As the Intermediate or 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 (instal-
lation 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 “Intermediate or Final Stage Manufacturer” and certifies that the vehicle complies with Federal Motor
Vehicle Safety Standards. (See Figure 2–2.) For Canadian final stage manufacturers see:
http://www.gazette.gc.ca/index-eng.html and http://www.tc.gc.ca/eng/acts-regulations/menu.htm for the regulations.

Section 2
Safety & Compliance
Noise
and Emissions Requirements
NOTE:
NOTE:
This truck may be equipped with a converter muffler unit in order to meet both noise and exhaust
emissions requirements.
Removal or tampering with the converter muffler will not improve engine per-
formance.
Also tampering is against the rules that are established by the U.S. Code of Federal Regu-
lations
and EnvironmentCanada Regulations. The converter muffler may only be replaced with an
approved par t.
Relocation of converter muffler will affect noise and emission performance. Contact the engine manu-
facturer
for any requirements and restrictions prior to an y modifications. In particular, there are re-
quirements
and restrictions for exhaust pipe materials and f or maximum exhaust system lengths from
turbo outlet to muffler
inlet.
