Section of door frame, 5D
|
In the following description, the door frame is joined at the top edge in front of the C-pillar and at the lower edge by the rear wheel housing. The side panel must be removed when the complete door frame is replaced.
1.
|
Position the car in an aligning bench and cross-measure if necessary.
|
2.
|
Drill out the spot-welds and remove the reinforcement on the outside of the wheel housing. The reinforcement can be refitted if it is undamaged.
|
3.
|
Grind down the seam-welds that secure the door frame to the front wheel housing.
|
4.
|
Cut the door frame as illustrated, see
Permissible joints
. Do not damage the reinforcement in the upper edge of the C-pillar.
|
5.
|
If the hinges are undamaged, cut the panel around the hinges.
If the hinges are damaged, remove them.
Drill out the spot-welds and tap loose the door frame. Drill out all welds in the lower flange of the lower edge.
|
6.
|
Align any deformed sheet metal or panels.
|
7.
|
Roughly cut the spare part so that it overlaps the joint by approximately three centimetres. Make cuts for the hinges if they are still in place.
|
8.
|
Fit the spare part and fixate with a couple of welding clamps.
|
9.
|
Cut through the spare part and the body at the same time so that the joints can be welded edge-to-edge.
|
10.
|
If the hinges have been removed:
Drill holes in the hinges as shown. Use 6 mm drill bit.
Rear doors, upper hinge:
A = 24.1, B = 30.2
Rear door, lower hinge:
B = 25.1, A = 30.2
|
11.
|
Drill holes for the hinge mountings in the spare part according to the pre-stamped punch marks in the B-pillar.
|
12.
|
Tighten the hinges with bolts and nuts.
|
13.
|
Drill holes for plug-welding on the rear of the spare part.
|
14.
|
Grind the surfaces to be welded on the spare part and the body.
|
15.
|
Apply welding primer on the surfaces to be plug and spot-welded. Use Teroson Zinkspray.
|
16.
|
Fit the spare part and fixate with a couple of welding clamps.
|
17.
|
Fit doors, front wing and bonnet, check and adjust the door openings.
|
18.
|
Fasten the hinges with a couple of welds.
|
19.
|
Remove the doors, front wing and bonnet.
|
20.
|
Spot-weld the door frame.
|
21.
|
Plug-weld the underside of the door frame.
|
22.
|
All-weld the joints on the door frame.
|
23.
|
Weld the hinges into place.
|
24.
|
Remove the nuts and bolts and weld shut the holes in the rear door hinges.
|
25.
|
Plug-weld the door frame to the front wheel housing.
|
26.
|
Weld on the reinforcement on the outside of the wheel housing.
|
28.
|
Remove any remaining welding primer. Welding primer reduces adhesion of paint, filler and sealant.
|
29.
|
Apply primer to all ground surfaces. Use Standox 1K Primer.
|
30.
|
Seal joints and sheet metal flanges with sealant. Use Terostat 1K-PUR.
|
31.
|
Apply anti-corrosion agent to the interior of the sill after painting. Use Terotex HV 400 or Mercasol 1.
