Front wheel housing and front frame member assembly

Front wheel housing and front frame member assembly

Certain weld joints on the car may be MIG brazed whereby the filler material is bronze rod. The characteristic sign of MIG brazing is that the joint is gold coloured. MIG brazing must always be replaced with new MIG brazing.

Warning

Repairs to MIG brazing using conventional welding methods and normal filler material are forbidden. Cracks can arise which can impair performance in a collision.


To remove


1. Position the car in an aligning bench.

2. Remove the front wing.

3. Remove the bumper member.

4. Remove the radiator crossmember.

5. Grind away the welds and drill out the spot-welds. Remove the reinforcement plate on the outside of the wheel housing. Note that the seam welds may be MIG brazed.


6. Drill out the spot welds securing the wheel housing and frame member to the bulkhead as illustrated.


7. Drill out the remaining spot welds and knock loose the wheel housing and frame member.


8. Dress and grind all the surfaces that have been spot welded.

9. Grind off the primer from the spare part where it is being welded.

10. Apply welding primer to the spare part and the body.


To fit



1. Put in place the frame member with a few welding clamps. Position the frame member using the alignment bench measuring system.

2. Weld on the rear edge of the frame member.

3. Put the wheel housing in position and fix it with a few welding clamps. Adjust its position exactly with the alignment bench measuring system.

4. Drill holes for plug welding the wheel housing.

5. Apply welding primer to the surfaces to be spot and plug welded.

6. Weld on the wheel housing.


7. Position the outer reinforcing member.

8. Weld on the outer reinforcing member.

Warning

Repairs to MIG brazing using conventional welding methods and normal filler material are forbidden. Cracks can arise which can impair performance in a collision.


9. Weld in the reinforcement plate on the outside of the wheel housing. Certain cars : Replace the MIG brazing.


10. Fit the bumper member.

11. Fit the radiator crossmember.

12. Grind the welds.

13. Remove any remaining welding primer. Welding primer reduces adhesion of paint, filler and sealant.

14. Apply primer to all bare metal surfaces.

15. Seal joints and seams with sealant.

16. Apply underseal to the underbody and in the wheel housing after painting. Use Terostat 9320.

17. Apply anti-corrosion agent to the interior of the frame member after painting. Use Terotex HV 400 or Mercasol 1.
