5.3 Drilling in vehicle chassis frame

  • Additional securing points for custom bodies.
    The longitudinal members are hollow profile beams. If holes have to be drilled in them, this should only be carried out in the neutral zone (centre of longitudinal member but with sufficient distance from flange). In addition, spacer sleeves should be welded in place (see Fig. 1!).

  • Drillings that were made in the factory in the upper and lower strap of the longitudinal members must not be made larger. Likewise, these drillings should not be used as fixture points for any type of auxiliary euipment

  • Drillings to allow passage of pipes, wiring, cables, etc., and for fixture of attachments (clamps, etc.).
    In exceptional circumstances, we will agree to drillings being made in the web plate of the longitudinal members or in the cross members. If this becomes necessary, it is essential that you contact us first.
  • When series production components are removed and subsequently installed, the torques specified in the "Installation guidelines for workshops" must be observed without fail.
