Bodywork flange: preparation for installing the sliding/tilting sunroof frame

If a (new or used) frame 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 frame. If an adhesive bead is not applied to the frame 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 - Electronic parts catalogue to the sheet metal parts where the paint has been damaged.
  • Shortly before re-applying the adhesive to the sliding/tilting sunroof, cut back the adhesive bead stuck to the bodywork flange 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.

Sunroof

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.

Undamaged sliding/tilting sunroof frame: preparing for installation and removal

Caution

If an undamaged sliding/tilting sunroof is reused, the adhesive sealing material strings (PUR) must be cut back.

It must be observed that the top adhesive beads (for connecting the sliding/tilting sunroof trim panel) and the bottom adhesive beads (for connecting to the bodywork) must be cut back.

The adhesive material strings are cut back shortly before reinserting the sliding/tilting sunroof frame. If an adhesive bead is not applied to the frame immediately after being cut, this must be "activated" with the glass activator - D 181 802 M1- .

  • Shortly before applying the adhesive to the frame, cut back the adhesive bead stuck to the frame to a height of 1 to 2 mm.

Sunroof

Note

  • In areas with tabs, as displayed in the figure, the adhesive material must be cut back until it is flush with the upper part of the tabs.
  • The remaining material is required as a base for the new adhesive sealing material (PUR).
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.

  • Remove the sliding/tilting sunroof frame and install according to the instructions.

    Follow the instructions accordingly.

  •  With a new frame, apply the material on the primer layer. Follow instructions below:

General requirements for applying the adhesive bead

Note In order to ensure for the homogeneous properties of the dual component mixture, apply a bead -a- with 10 cm to a clean surface and dispose of the first piece of the product.

  • The sleeve -2- must rest flush.
  • Hold the gun permanently at right angles to the parts being treated.

WARNING

The glass must be fitted before 10 minutes elapse, as the adhesive properties of the adhesive sealing material (PUR) are reduced after that time.

  • Attach a rope -2- in the upper area of the window -1- underneath the sealing lip -3-.

Note

  • Keep the rope in this position until the bonding process for the sliding/tilting sunroof frame is completed.
