The following operation steps are shown on the left side of the vehicle on model 257. In case of damage on the right side of the vehicle, these steps must be performed analogously.

Additional information can be found in the superordinate service document.

The safety information in the superordinate service document must be observed.

1. Install A-pillar reinforcement (6) with the side portal frame and portal straightener, fit, and fix in place.

   Use spacers.

2. Drill rivet holes with a diameter of 6.7 mm in A-pillar reinforcement (6) from the inside through the existing holes in the body (area A).
3. Remove portal bracket and A-pillar reinforcement (6).
4. Deburr rivet holes on A-pillar inner panel (6) and body on both sides.

10. A-pillar reinforcement (6) (areas J).
11. A-pillar reinforcement (6) (areas L).

    Inert gas weld in intervals and allow welding area to cool down in between. Reduces heat distortion.

12. Grind inert gas welds down flat on A-pillar reinforcement (6) (areas L).

    Grind down flat beaded areas and contact surfaces on B-pillar paneling only.

13. Clean welding areas which are no longer accessible after installing upper front longitudinal member and A-pillar paneling and coat with zinc dust paint.

14. Install front top longitudinal member (1), fit with welding fixture and adapter set, and fix in place.
15. Install reinforcement (3), fit and fix in place.
16. Drill rivet holes with a diameter of 6.7 mm in front top longitudinal member (1) and reinforcement (3) (areas M, N, O).

    Drill rivet holes from inside through present hole in body (area N).

17. Remove front top longitudinal member (1), reinforcement (3), welding fixture, and adapter set.
18. Deburr rivet holes on upper front longitudinal member (1), reinforcement (3) and body on both sides.
19. Remove drilling chips.
20. Coat inside of riveted joint with zinc dust paint (areas O).

27. Install strut (2) and bracket (4), fit and fix in place.
28. Drill rivet holes with a diameter of 6.7 mm in strut (2) and bracket (4) (areas R, S).
29. Remove strut (2) and bracket (4).
30. Deburr rivet holes on strut (2), bracket (4) and body on both sides.
31. Remove drilling chips.
32. Coat insides of riveted joints in areas not bonded with zinc dust paint.

    Do not apply zinc dust paint to bonding surfaces.

    Otherwise adhesion problems may occur.

33. Apply 2-component adhesive to body in crosshatched areas.

    Observe pretreatment of bonding surfaces and manufacturer's specifications for drying and processing time of 2-component adhesive.
