6.6 Frame modifications
• The maximum permissible axle loads must not be exceeded, while the minimum front axle load must be
exceeded.
• Rear underride guard: fastened in the same way as on a standard vehicle.
• Extend the mounting frame to the end of the frame.
6.6.1 Precautions for modification
In the case that a rear body of special design is mounted or the vehicle is to be used in special conditions, use
utmost care that neither the structure nor the strength of the frame is impaired during mounting or modification
work.
When mounting a rear body of special design, pay full attention to even weight distribution on the frame.
Refer to "10.5.2 Frame section modulus" É 10.5.2.
Attaching stiffeners, drilling holes or welding objects to the frame can affect the strength of the frame greatly,
possibly resulting in a deformed or cracked frame. Avoid performing any unnecessary reinforcement, drilling or
welding work on the frame.
6.6.2 Extending and shortening
• Frame rear overhang extending procedure
Perform the following steps to extend the frame rear overhang.
• Extension members
As high tensile strength steel (540 MPa class) hardens more easily at welds than automotive structural
steel (MJSH440), follow the instructions below.
(a) Be sure to use a low-hydrogen type electrode. Especially, where the weld must have the same strength
level as the base metal, use a low hydrogen, high tensile strength type electrode.
(b) Short weld beads are more likely to crack due to low hardening rate, so in areas requiring many short weld
beads, perform continuous welding instead.
