Replacement part preparation

WarningWhen cleaning the mating edges, use scouring wheels only to avoid damaging the anticorrosion protection

Distance A = 800 mm

Distance B = 900 mm

Mark at "a" in the cutting zone "A", then cut

Mark at "b" in the cutting zone "B", then cut

NoteThe dimensions "A", "B" are given as an indication only and may change depending on the different circumstances of replacement of the centre pillar

Prepare the mating edges and protect them using a weldable primer (index "C7")

NoteApply the weld-through primer on the internal faces of the panels to be welded

Cutting of the part on the body

Distance C = 240 mm

Distance D = 330 mm

Mark (at "c") in the cutting zone "C" then cut

Mark (at "d") in the cutting zone "D" then cut

NoteThe cutting lines C, D are given as a guide. the dimensions may change depending on the different circumstances of replacement of the centre pillar

Distance E = 320 mm

Distance F = 200 mm

Mark (at "e") in the cutting zone "E" then cut

Mark (at "f") in the cutting zone "F" then cut

NoteThe cutting lines E, F are given as a guide. the dimensions may change depending on the different circumstances of replacement of the centre pillar

Cut out the spot welds

Detach the centre pillar at the inflating inserts (3); using a hot air gun

Remove: the centre pillar

Cleaning and preparation of the body

Prepare the mating edges and protect them using a weldable primer (index "C7")

NoteApply the weld-through primer on the internal faces of the panels to be welded

Prepare the mating edges

Position the inflating insert (3)

Seal the inflating insert (3)

Adjustment

Position: the centre pillar

Position the components used for adjustment

Check the fits and clearances

Adjust the cuts (if necessary)

Holds the part in position

Welding

WarningThe number of spot welds necessary for the assembly of a new part must be identical to the number of spot welds fixing the original part

Weld by MAG bead (at "g")

Grind the MAG weld beads

Weld by MAG bead (at "h")

Grind the MAG weld beads

Weld with electric spot welds

Sealing protection

Apply a phosphate-print layer to the zones laid bare

Apply index "C4" underseal protection

Painting, then spraying of the index "C5" product into the hollow sections in the repair zone

Additional operations

Refit the electrical harnesses and the components removed

Reinitialisation

Reactivate the pyrotechnic systems

WarningPerform the operations to be carried out following reconnection of the battery

Reconnect the battery
