Chassis Frame
Frame side rails are heat treated. No welding is permitted because structural failure may result. Do not drill through either top or bottom flanges. A warning label is also attached to the frame for information. Drilling is permitted in the frame web in accordance with a specified hole spacing pattern. Consult a Volvo Truck dealer to obtain approved hole spacing dimensions or refer to the Frame Rail and Cross Member Service Manual. Frame rail and cross member nuts and bolts should be checked periodically and tightened to the specified torque if necessary.

Frame Alterations
Under no circumstances can the frame be cut and an extension piece added to increase the wheelbase. The only alteration allowed is wheel base shortening, where the only change in the frame rail is a new hole pattern drilled for the new location of the rear suspension.
