This manual provides 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 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 Model 220 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 involved in the vehicle definition and ordering process. Early in the process, professional body builders can often contribute valuable information that reduces the ultimate cost of the body installation.
The DAVIE4 diagnostic tool is recommended for all Model 220’s built with the push button transmission shifter. The DAVIE3 (XDc) tool should be used with all Model 220’s built with the lever style transmission shifter. Both DAVIE4 and DAVIE3 should be connected to the blue, 16-pin OBD connector located on the passenger side of the dash. Contact your local Peterbilt dealer to utilize the DAVIE tools or order the required hardware and software.
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 Department 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 ordered from your local dealer.
OVERALL DIMENSIONS
This section includes drawings of the base Model 220, which includes: On the pages that follow, detail drawings show particular views of each component of the vehicle. They illustrate important measurements critical to designing bodies of all types. See the “Contents” at the beginning of the manual to locate the drawing you need.
FRAME AND CAB RELATED HEIGHTS
The bottom of the frame rail (BOF) at the front and rear axle can be used as a reference point to estimate vertical heights. Use the following to calculate estimates for frame and cab related heights, such as top of frame rail, step height, top of exhaust pipe, etc.:
- Tire radius data from the manufacturer
- Front and rear suspension ride heights in this section
- Frame rail heights defined in this section if needed
- Component dimensions from bottom of rail defined in this section if needed
Note that there are many factors that will affect heights including, but not limited to, front and rear axle loading and tire pressure. Placement of frame components such as fuel tanks will affect loads on the front axle and rear axle, as well as distribution to the left and right sides of the vehicle. Heights calculated from this information are estimates only.
PTO Clearances
The following visuals are provided to help or aid in determining PTO locations and clearances. For specific dimensions please work through your local Peterbilt dealer. Multiple PTO’s are shown for layout purposes only. Power equipment, i.e., drive shafts & power pumps are not included. Body builders should select the appropriate Chelsea or Muncie 24V electric over air PTO’s for their application and customer requirements.
The following section is designed to give you information regarding the exhaust and after-treatment systems on Peterbilt chassis. All Peterbilt’s equipped with 2017 emission level engines will utilize Selective Catalyst Reduction (SCR). SCR is a process in which Diesel Exhaust Fluid (DEF) is injected into the exhaust downstream of the engine. DEF is converted to ammonia by the heat of the exhaust system. Inside of the SCR canister, a catalyst causes a chemical reaction between the ammonia and NOx, turning it into water and nitrogen. For more information on the specific details of how SCR works, please contact your local Peterbilt dealer.
On most Peterbilt chassis, the DEF Supply Module (or pump) is integrated into the DEF tank. Peterbilt does not allow relocation of this pump. The following schematic details how the DEF lines route to the after-treatment system.
