The higher-level service document as well as the safety information in the service document must be observed.

1. Install B-pillar (2) with the side portal frame and portal straightener, fit and fix in place.

   Use spacers.

2. Drill rivet holes in the B-pillar (2) that have a diameter of 6.7 mm (areas A, B).
3. Countersink rivet holes (area B).
4. Drill 6.5 mm-diameter holes for plug welding (areas C).

   Only drill holes for plug welding through one panel thickness (areas C).

5. Remove B-pillar (2) and the portal straightener.
6. Deburr rivet holes an B-pillar (2) and on body on both sides.
7. Remove drilling chips.
8. Coat with zinc dust paint insides of those riveted joints that will not be bonded.

9. Apply sealant to B-pillar foam part (2) in cross-hatched area (area D).
10. Apply 2-component adhesive to B-pillar (2) in cross-hatched areas (areas E).

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