Remove A-Pillar Together With Side Longitudinal Member - Ar63.20-P-1150-01GQ

Model 166, 292 

The following steps are shown on the left side of the vehicle and must be accomplished analogously on the right side in the event of damage.

1. Scribe separating points on A-pillar outer paneling (1) (areas A₁ and A₂ ).

   Separating point (area A₁ ) is the bottom edge on the upper outer longitudinal member (arrow). Measure separating point (area A₂ ) from Y-marking (arrow).

   Removal  : a = approx. 150 mm

2. Cut A-pillar outer paneling (1) at separating points (areas A₁ and A₂ ).

   Do not make the cuts too deep.

   Otherwise the components below can be damaged and weakened.

3. Expose spot welds on A-pillar paneling (1) and cut out (areas B₁ and B₂ ).
4. Remove damaged A-pillar outer paneling (1).

5. Scribe separating point on A-pillar reinforcement (2) (areas C₁ and C₂ ).

   Measure separating point (area C₁ ) from bottom edge of upper outer longitudinal member (arrow). Measure separating point (area C₂ ) from side longitudinal member separating point (arrow).

   Removal  : b = approx. 150 mm c = approx. 90 mm

6. Cut A-pillar reinforcement (2) at separating point (areas C₁ and C₂ ).

   Do not make the cuts too deep.

   Otherwise the components below can be damaged and weakened.

7. Expose spot welds on A-pillar reinforcement (2) and cut out (areas D₁ , D₂ and D₃ ).
8. Drill Ø 6.7 mm spot welds in A-pillar inner section (3) (area E).
9. Heat A-pillar reinforcement (2) in crosshatched areas.

   Cross-hatched area is bonded.

10. Remove damaged A-pillar reinforcement (2).

11. Scribe separating point on A-pillar inner section (3) and cut (area D and G).

    Measure separating point (area G) from top edge of side longitudinal member to A-pillar inner section (3) (arrow). Measure separating point (area D) from Y-marking (arrow).

    Removal  : d = approx. 350 mm e = approx. 400 mm

12. Scribe separating point on A-pillar inner section (3) and cut (areas D and G).

    Do not make the cuts too deep.

    Otherwise the components below can be damaged and weakened.

13. Expose spot welds on A-pillar inner section (3) and cut out (areas F₁ , F₂ , F₃ and H).
14. Remove damaged A-pillar inner section (3).

15. Scribe separating point on A-pillar inner section (3) (area J).

    Measure separating point (area J) from separating point on A-pillar (arrow).

    Removal  : f = approx. 30 mm

16. Cut A-pillar inner section (3) at separating point (areas J).

    Do not cut too deeply.

    Otherwise the components below can be damaged and weakened.

17. Expose spot welds on A-pillar inner section (3) and cut out (areas I₁ and I₂ ).
18. Remove remaining A-pillar inner section (3).
19. Grind mating surfaces down to bare metal in the cross-hatched inner C-pillar sidewall.

    Sand down spot weld flanges to bare metal on both sides.

20. Remove shavings and drill chips.
21. Coat insides of spot welding flanges with zinc dust paint.
