Body Mounting
BODy MOUNTING USING U–BOLTS
Spacers
If the body is mounted to the frame with U–bolts, use a hardwood sill (minimum 1/2 inch (12 mm) thick) between the frame
rail and body frame to protect the top surface of the rail flange.
Do not allow the frame rails or flanges to deform when tightening the U–bolts. It will
weaken the frame and could cause an accident. Use suitable spacers made of steel or
hardwood on the inside of the frame rail to prevent collapse of the frame flanges.
Use a hardwood spacer between the bottom flange and the U–bolt to prevent the U–bolt from notching the frame flange.
See Figure 6–11.

Acceptable U-Bolt Mounting with Wood and Fabricated Spacers [inch (mm)]
Do not allow spacers and other body mounting parts to interfere with brake lines, fuel
lines, or wiring harnesses routed inside the frame rail. crimped or damaged brake lines,
fuel lines, or wiring could result in loss of braking, fuel leaks, electrical overload or a fire.
carefully inspect the installation to ensure adequate clearances for air brake lines, fuel
lines, and wiring. See Figure 6–12.
Mount U–bolts so they do not chafe on frame rail. Failure to do so could result in
premature wear of the U-bolt or frame rail.
