BODY MOUNTING
Peterbilt Motors Company 4-3
BODY MOUNTING USING BRACKETS
CAUTION: Always install a spacer between the body subframe and the top flange of the frame rail. Installation of
a spacer between the body subframe and the top flange of the frame rail will help prevent premature wear of the
components due to chafing or corrosion.
WARNING! When mounting a body to the chassis, DO NOT drill holes in the upper or lower flange of the
frame rail. If the frame rail flanges are modified or damaged, the rail could fail prematurely and cause an
accident. Mount the body using body mounting brackets or Ubolts.
FRAME SILL
If the body is mounted to the frame with brackets, we recommend a frame sill spacer made from a strip of rubber or plastic
(delrin or nylon). These materials will not undergo large dimensional changes during periods of high or low humidity. The
strip will be less likely to fall out during extreme relative motion between body and chassis. See FIGURE 4-3.
