Removal

Check if any of the connected parts are deformed by checking body alignment dimensions. Use appropriate measurement tools (reference rigs, templates or gauges).

Straighten the body if necessary.

Use a rotary brush to clean the areas to be ground in order to expose the weld spots.

1 Drill out the weld spots shown in the figure.

2 Use a circular saw to follow the cutting lines shown in the figure.

3 Cross-sections of key areas as a guide to allow the operator to adjust cutting position and depth in order to avoid damage to the underlying panels.

4 Use a chisel and hammer to remove the rail section from the car.

Straighten the panel edges using a mallet and profiled stake.

Use a grinding wheel to remove the weld spot residues.

1 Apply the electroweldable paint finish to the areas shown in the figure.

Refitting

Cut the rail section at the bench. Take care to leave a sufficiently wide section of steel to attach the new part to.

1 Position the part on the car and secure using self-locking grippers and a template.

2 Use a circular saw to trim the panel and remove excess parts.

Remove the part from the car.

1 Make a hole as shown in the figure.

Working at the bench, use a rotary brush to remove the corrosion-proofing from the areas shown in the figure.

2 Apply the electric weld paint finish to edges in contact with the car.

1 Position the part on the car and secure using self-locking grippers.

2 Use a MIG welder to seam weld along the line shown in the figure.

3 Use a MIG welder to fill the holes made previously.

Correct any deformations in the panel using a profiled stake and mallet.

1 Use a grinding wheel to level weld residues and remove.
