CHASSIS MODIFICATIONS 2-17 E UROCARGO Euro 4/5 Figure 2.5 91447 g) On the inner side reinforcing L-section flitches should be applied. These should be made of steel and have the same characteris- tics as the steel used for the chassis. The minimum dimensions are given in Figure 2.3. The reinforcements may only be fixed to the vertical web of the side member using welding beads, plug welds, bolts or rivets (Huck rivets may also be used). The cross-section and the length of the weld bead, the number and distribution of the plug welds, bolts or rivets must be ad- equate to transmit the bending and shearing moment of the section.
2.3.5 Closing of existing holes If, when making new holes, the existing holes are found to be too close (see Figure 2.2) these may be closed up by welding. To ensure the success of this operation the outer edge of the hole should be chamfered and copper plate used for the inner part. For holes with a diameter of over 20 mm, chamfered plugs may be used, welded on both sides. Drilling the chassis Print 603.93.431 Base - January 2008
