B pillar, five-door body
B pillar, five-door body |
The sill is reinforced. This reinforcement must not be damaged when the B pillar is cut.
Important | ||
Body reinforcement components should be cut and joined only if they are specifically covered in the description of methods. Unless otherwise stated, a damaged reinforcement component must be discarded and a new one fitted in its place. This is mandatory. |
||
1. |
Cut away the B pillar. B pillar joints, see
Joints. Be careful that the underlying metalwork is not damaged.
|
2. |
Cut the inner part of the B pillar above the seam welds at the lower end.
|
3. |
Drill out the spot welds.
|
4. |
Drill out the spot welds in the inside of the B pillar at the upper end and remove the B pillar.
|
5. |
Realign any deformed metalwork.
|
6. |
Use a grinder to clean the areas on the new reinforcement and body that are to be welded.
|
7. |
Position the reinforcement component and fix it with a few welding clamps.
|
8. |
Cut the B-pillar's outer panel roughly to size so that it will overlap the joint by about three centimetres.
|
9. |
Drill holes for plug welding in the outer panel.
|
10. |
Drill holes for the hinge mountings at the pre-stamped punch marks in the outer panel.
|
11. |
Drill holes for the hinges as shown.
Upper hinges: A = 24.1 mm, B = 30.2 mm Lower hinges: A = 25.1 mm, B = 30.2 mm |
12. |
Screw the hinges to the outer panel with nuts and bolts. Scratch round the hinge to mark its position on the outer panel.
|
14. |
Use a grinder to clean the areas on the outer panel and body that are to be welded.
|
15. |
Position the outer panel and fix it with a few welding clamps.
|
16. |
Roughly cut the B-pillar's new inner part.
|
17. |
Position the spare part and fix it with a few welding clamps. Cut through the rear edge of the spare part and roof member simultaneously so that the joint can be welded edge-to-edge.
|
18. |
Cut through the outer panels of the B pillar and door frame simultaneously so that the joints can be welded edge-to-edge.
|
19. |
Mark the positions where holes for plug welding are to be drilled in the inner part at the top.
|
20. |
Remove the spare part and drill holes for plug welding.
|
21. |
Use a grinder to clean the areas on the spare part and the body that are to be welded.
|
22. |
Apply welding primer to the surfaces which are to be spot and plug welded. Use Teroson Zinkspray.
|
23. |
Position the spare part and fix it with a few welding clamps. Spot weld the inner part to the outer part and the reinforcement component.
|
24. |
Weld the joint at the lower end of the inner part.
|
25. |
Plug weld the upper parts of the inner part and reinforcement to the roof member.
|
26. |
Weld the joint between the inner part and the roof member.
|
27. |
Plug weld the outer panel to the reinforcement.
|
28. |
Grind the welds clean.
|
29. |
Weld the lower end of the outer panel.
|
30. |
Spot weld the upper end of the B pillar in place.
|
31. |
Weld the roof member joints.
|
32. |
Weld the sill joints.
|
33. |
Apply welding primer to the surfaces which have been ground clean. Use Teroson Zinkspray.
|
34. |
Screw the hinges in place with nuts and bolts.
|
35. |
Hang the door on and check its fit. Adjust as necessary and then fix the hinges with a couple of tack welds.
|
36. |
Weld the hinges in place.
|
37. |
Remove the nuts and bolts and weld up the holes in the hinges.
|
38. |
Grind the welds clean.
|
39. |
Wash off surplus welding primer. Welding primer makes for poorer adhesion of paint, filler and sealant.
|
40. |
Apply primer to all surfaces that have been ground clean. Use Standox 1K Füllprimer.
|
41. |
Seal joints and metal folds with putty. Use Terostat 1K-PUR.
|
42. |
Apply anti-corrosion agent to the lower end of the B pillar on the inside after painting. Use Terotex HV 400 or Mercasol 1.
