  1. Install side longitudinal member paneling (1), fit, and fix in place.
  2. Drill rivet holes with a diameter of 6.7 mm in side longitudinal member paneling (1) (areas A, B).
  3. Countersink rivet holes (area B).
  4. Remove side longitudinal member paneling (1).
  5. Deburr rivet holes in side longitudinal member paneling (1) and in body on both sides.
  6. Remove drilling chips.
  7. Coat insides of riveted joints on which no adhesive is applied with zinc dust paint.

  10. Install side longitudinal member paneling (1) and fix in place.
  11. Rivet side longitudinal member paneling (1) with a 6.4x12 rivet (areas D).
  12. Rivet side longitudinal member paneling (1) with countersunk-head blind rivet with a diameter of 6.4x14.0 (area E).
  13. Side longitudinal member paneling (1) POLARIZATION RESISTANCE SINGLE-ROW SPOT WELD (areas G).
  14. Side longitudinal member paneling (1) SHIELDED GAS SEAM WELD (areas H).

    IMPORTANT

    Perform inert gas welding at intervals and allow to cool down in between. This reduces heat distortion.

  15. Surface grind inert gas welds (areas H).
  16. Solder surfaces of side longitudinal member paneling (1) with body solder and smooth (areas H).

    IMPORTANT

    A basic body filler can also be used as an alternative to the restoration of the surfaces with body solder.
