Removal

See Op. 7210E51 Left rear wing .

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.

1 Use a pneumatic saw to cut along the lines shown in the figure.

2 Use a circular saw to cut along the 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 Remove the spot welds shown in the figure using a chamfering machine.

5 Use a drill to crop the spot welds shown in the figure.

6 Remove the rear wing frame 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 electric weld paint finish to the newly-treated panel edges.

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

2 Make equidistant holes as shown in the figure.

3 Use a rotary brush to remove the corrosion-proofing from around the inner and outer edge.

Apply electroweldable paint finish to the edges in contact with the car.

Refitting

1 Position the rear wing frame correctly on the car and secure using self-locking grippers.

Check it is properly aligned.

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

3 Use a pneumatic saw to trim the panels and remove excess parts.

1 Use a spot welder to weld the areas shown in the figure.

2 Use a MIG welder to seam weld the panel edges trimmed previously.

3 Use a MIG welder to fill the holes shown in the figure.

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

Use a grinding wheel to level weld residues and remove.

1 Apply rust-proofing to newly welded areas.

2 Seal the rear wing frame joint lines.

3 Apply foam as shown in the figure.

Apply paint.

4 Apply wax oil inside the rear wing frame.
