Op. 7210E28 ROOF PANELCheck 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 hacksawing machine to follow the cutting lines shown in the figure.2. 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.Remove the paint from around the edge of the roof connection profile using a rotary brush to reveal weld points.3. Use a chamfering machine to remove the weld spots shown.4. Drill out the spot welds indicated.Use a chisel and mallet to remove spots drilled previously.5. Remove the connecting section.
Straighten the panel edges using a hammer and profiled stake.Use a grinding wheel to remove the spot weld residues.Use a rotary brush to clean treated areas.1. Apply the electroweldable paint finish.
1. Cut the part at the bench. Take care to leave a sufficiently wide section of steel to attach the new part.2. Use a grinding wheel to remove the corrosion-proofing from around the inner and outer edge of the parts.3. Drill out the holes indicated.Apply electric weld paint finish to the edges to be welded.

1. Fit the part correctly on the car using self-locking grippers.2. Fit the door compartment seal, striker and front door.3. Fit the tail-gate seal and tail-gate.Check the alignment and ensure the surrounding gaps are even.
1. Use a circular saw to cut both panel sections in order to achieve a perfect joint line.Remove any excess sheet steel and adjustment components from the part.
1. Fit the part correctly on the car using self-locking grippers.2. Use a spot welder to weld the areas shown in the figure.3. Use a spot welder to made a few spot welds: the part will be fully welded when the roof panel is fitted.4. Use a MIG welder to seam weld the areas shown in the figure.5. 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 the weldsUse a rotary brush to clean the newly-welded areas.
1. Apply rust-proofing to newly-welded areas.2. Apply heat expanding sealant through the hole in the windscreen opening pillar indicated by the arrow. Seal the joint lines between the part and the car.Apply paint.
