SECTION 1 INTRODUCTION
The Peterbilt 520 Body Builder Manual was designed to provide body builders with a comprehensive information set to
guide the body planning and installation process. Use this information when installing bodies or other associated
equipment.
This manual contains appropriate dimensional information, guidelines for mounting bodies, modifying frames, electrical
wiring information, and other information useful in the body installation process.
The Peterbilt 520 Body Builder Manual can be very useful when specifying a vehicle, particularly when the body builder is
involved in the vehicle definition and ordering process. Information in this manual will help reduce overall costs through
optimized integration of the body installation with vehicle selection. Early in the process, professional body builders can
often contribute valuable information that reduces the ultimate cost of the body installation.
In the interest of continuing product development, Peterbilt reserves the right to change specifications or products at any
time without prior notice. It is the responsibility of the user to ensure that he is working with the latest released information.
Check Peterbilt.com for the latest released version.
If you require additional information or reference materials, please contact your local Peterbilt dealer.

NOTE
FEDERAL MOTOR VEHICLE SAFETY STANDARDS AND COMPLIANCE
As an Original Equipment Manufacturer, Peterbilt Motors Company. ensures that our products comply with all applicable
U.S.
or Canadian Federal Motor Vehicle Safety Standards. However, the fact 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 was
incomplete when it left the build plant.
Incomplete Vehicle Certification
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.
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 any
of the components or systems covered by these regulations, it is your responsibility as the Intermediate or
Final Stage Manufacturer to ensure that the complete vehicle is in compliance with the particular
regulations upon completion of the modifications.

FIGURE 2-2. Locations of Certification Labels - Driver’s Door and Frame
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 (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 “Intermediate or Final Stage Manufacturer” and certifies that the
vehicle complies with Federal Motor Vehicle Safety Standards. (See Figure 2–2.) Be advised that regulations affecting the
intermediate and final stage manufacturer may change without notice. Ensure you are referencing the most updated copy
of the regulation during the certification and documentation processes.
In part, if the final stage manufacturer can complete and certify the vehicle within the instruction in the incomplete vehicle
document (IVD) the certification label would need a statement that reads, “This vehicle has been completed in accordance
with the prior manufacturers‚ IVD where applicable. This vehicle conforms to all applicable Federal Motor Vehicle Safety
Standards [and Bumper and Theft Prevention Standards if applicable] in effect in (month, year).”
However, if the vehicle cannot be completed and certified with in the guidance provided in the IVD, the final stage
manufacturer must ensure the vehicle conforms to all applicable Federal Motor Vehicle Safety Standards (FMVSS). The
final stage manufactures certification label would need a statement that reads, “This vehicle conforms to all applicable
Federal Motor Vehicle Safety Standards [and Bumper and Theft Prevention Standards if applicable] in effect in (month,

Noise and Emissions Requirements
NOTE
This truck may be equipped with specific emissions control components/systems* in order to
meet applicable Federal and California noise and exhaust emissions requirements. Tampering with
these emissions control components/systems* is against the rules that are established by the
U.S Code of Federal Regulations, Environment Canada Regulations and California Air Resources
Board (CARB). These emissions control components/systems* may only be replaced with original
equipment parts.
Additionally, most vehicles in North America will be equipped with a Greenhouse Gas (GHG)
“Vehicle Emission Control Information” door label indicating its certified configuration. The vehicle
components listed on this label are considered emission control devices.
Modifying (i.e. altering, substituting, relocating) any of the emissions control components/systems
defined above will affect the noise and emissions performance/certification. Modifications that
alter the overall shape and aerodynamic performance of a tractor will also affect the emission
certification. If modifications are required, they must first be approved by the manufacturer.
Unapproved modifications could negatively affect emissions performance/certification. There is no
guarantee that proposed modifications will be approved.
Tires may be substituted provided the new tires possess a Coefficient of rolling resistance (Crr)
equal to or lower than Crr of the original tires. Consult with your tire supplier(s) for appropriate
replacement tires.
Contact the engine manufacturer for any requirements and restrictions prior to any modifications.
•
For Cummins Contact 1-800-DIESELS or your local Cummins distributor. Reference AEB 21.102.
It is possible to relocate the DEF tank; however the relocation requirements need to be followed. Any variances from the
relocation requirements may cause the emissions control components/systems to operate improperly potentially resulting
in engine de-rate.
NOTE
All 2017 engine emissions certified vehicles will be equipped with an On-Board Diagnostics (OBD)
system. The OBD system is designed to detect malfunctions of any engine or vehicle
component that may increase exhaust emissions or interfere with the proper performance of the
OBD system itself All diesel engines will be equipped with an On-Board Diagnostics (OBD)
system. The OBD system consists of computer program on one or more of the vehicle’s Electronic
Control Units (ECUs). This program uses information from the control system and from additional
sensors to detect malfunctions. When a malfunction is detected, information is stored in the
ECU(s) for diagnostic purposes. A Malfunction Indicator Light (MIL) is illuminated in the dash to
alert the driver of the need for service of an emission-related component or system.
To ensure compliance to emissions regulations, the final configuration of certain features of the completed vehicle
