Removing ( Refitting ) - Check that the components connected are not distorted by checking the bodyshell alignment measurements using suitable equipment (gauges, templates or jigs).- Straighten the body as necessary. 1. Use a hack sawing machine following the cutting lines shown in the diagram.- Use a rotary brush to remove the paint to gain access to the spot welds.2. Use the chamfering machine to remove the spot welds shown in the diagram.- Use the drill and chamfer the spot welds not accessible with the chamfering machine.- Use the hammer and chisel and remove the spot welds chamfered previously.3. Remove the part from the vehicle separating the edges joined by heat expanding sealant.- Remove the offcuts from the vehicle. - Straighten the edges of the vehicle using a mallet and profiled block.- Remove the spot weld residues using a disc grinder.- Use the rotary brush and remove the heat expanding sealant residues on the vehicle.- Use a rotary brush to clean the areas treated previously.1. Apply electro-galvanizing paint. 1. Work at the bench and cut the replacement wing, at the points shown in the diagram, making sure that a section of the panel remains for overlapping.2. Remove the anti-corrosion treatment from the entire perimeter of the inside and outside of the replacement part using a rotary brush.3. Drill the part at the points shown using the drill.- Apply electro-weldable paint to the edges involved. Refitting ( Removing ) 1.

Position the replacement part correctly on the vehicle and secure it using self-locking clamps.- Check the alignment and the surrounding gaps.2. Use a spot welder in the areas shown in the diagram.3. Use a MIG welder and weld the openings made previously in the replacement part.4. Use a MIG welder to seam weld in the join areas. - Correct any distortions to the panel using a hammer and dolly block.1. Use a disc grinder to level the welds.- Use a rotary brush to clean the areas welded previously. 1. Apply anti-oxidant protection to the areas involved in the welding.- Seal the join lines between the replacement part and the vehicle.- Proceed with the painting stage.- Apply the wax based oil protection to the inside of the rear wing
