Seat Leon >> Preparing body flange for installation

If a (new or used) window has to be installed, the adhesive bead and adhesive sealing material (PUR) must be cut back from the body flange. For this purpose follow these instructions:

Caution
  • Cut back the adhesive bead shortly before mounting the window. If an adhesive bead is not applied to the window immediately after being cut, this must be "activated "with the glass activator - D 181 802 M1- .
  • Do not allow activator to make contact with paint, danger of damage!
  • Protect the surrounding painted components accordingly.
  • Apply zinc spray.
  • Shortly before re-applying the adhesive to the window, cut back the adhesive bead stuck to the window to a height of 1 to 2 mm using the electric knife - SAT 1561A- and set of blades - SAT 1561/20- .

Note

  • The remaining material is required as a base for the new adhesive sealing material (PUR).
  • If the bodywork flange has been reworked or partially replaced, after painting, the new zone must be cleaned and primed correspondingly.
Caution

The bonding surfaces must be free of dust and grease.

Do not apply primer to the previously cut-back adhesive bead and do not treat with solvent.

Only for the windscreen flange

Note To ensure the correct seating between windscreen and body flange, you must insert distance blocks on each side.

  • Place the distance block -1- in the body flange. In order to do this, remove the bead of adhesive sealant material (PUR) from the body on both sides; this applies to the zone defined by the -dimension of approx. C= 80 mm -. For this purpose take the fourth rivet -3- as reference point (measured from the top edge of the mounting of the water drainage strip).

Glazing

Note Clean the zone defined by -dimension c- with isopropyl alcohol or heptanol.

  • Bond a new distance block into both sides. When doing so observe that -dimension a- = 17 mm to the fourth rivet -3- (measured from the top edge of the mounting of the water drainage strip).
  • Dimension b- = 40 mm (approximate length of the distance block).

Note

  • The embedded marking on both sides of the body -2- indicates the bonding zone for the distance block.
  • Depending upon the production status of the vehicle it is possible that the bodywork does not have any such markings.-2-.

Touching up paint damage

Repair paint work according to specifications in - repair guidelines for vehicle paint work ; if necessary, perform recommended corrosion protection measures.

For damage to paintwork in unseen zones, proceed as follows:

  • Repaint twice (wet on wet) leaving both coats to air.

Cleaning off excess adhesive

  • Use of glue removal is recommended for cleaning - Electronic parts catalogue . Observe safety precautions when using.
WARNING

When cleaning from the inside of the vehicle, do not press the newly-placed glass outwards.

  • First clean painted surface as well as possible using a dry cloth. Remove contamination residues with glue remover - Electronic parts catalogue .
  • Cleaning plastic trims: Allow the sealant to harden (approx. 1 hour) and then remove.
