Body Mounting Using Brackets
Always install a spacer between the body subframe and the top flange of the frame rail.
Failure to do so could result in corrosion due to dissimilar materials.
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.
Frame Sill
If the body is mounted to the frame with brackets, we recommend that the frame sill spacer be made from a strip of rub-
ber 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 6–3.

Brackets
When mounting a body to the chassis with brackets, we recommend designs that offer limited amount of relative move
-
ment, bolted securely but not too rigid. Brackets should allow for slight movement between the body and the chassis. For
instance, Figure 6–4 shows a high compression spring between the bolt and the bracket .

Another possibility is mounting a rubber spacer between the brackets . See Figure 6–5 .
These designs will allow relative movement between the body and the chassis during extreme frame racking situations.
Extreme frame racking, with rigid mountings, could cause damage to the body . This is particularly true with tanker
installations .
