7.
|
Cut the new frame member roughly to size.
|
|
8.
|
Fit the spare part in position, using the holes in the frame member to align it. Adjust its position exactly, checking the alignment by means of the aligning bench's coordinate measuring system, and fix it with a few welding clamps.
|
|
9.
|
Cut the existing frame member precisely in line with the rear edge of the spare part.
|
|
10.
|
Remove the spare part and realign any deformed metalwork.

Hang the wing, bonnet and radiator member in place and check the alignment of the spare part.
|
|
16.
|
Secure the cross-member and frame member with a couple of tack welds.
|
|
17.
|
Remove the wing, bonnet, wheel housing and radiator cross member. All-weld the joints on the frame member and weld the cross member.
|
Note
|
|
If the wheel housing is fitted:
|
|
Cut an opening in the wheel housing and all-weld the internal reinforcement of the frame member. Weld the opening.
|
|
|
18.
|
Go over the welds with a grinder.
|
|
19.
|
Apply primer to all surfaces that have been ground clean. Use a high-quality primer such as Standox 1K Füllprimer.
|
|
20.
|
Seal joints and metal folds with putty. Use Terostat 1K-PUR, part No. 30 15 426.
|
|
21.
|
Apply underseal to the underbody and in the wheel housing. Use Terostat 9320.
|
|
22.
