Attach special tool 51 3 010 twice to tool trolley. Moisten suction surfaces and secure rear window from outside.

If reusing the removed rear window, remove the adhesive residue with a blunt scraper or knife.

Observe treatment of adhesive area in body-cutout and on rear window, see 51 31 ... INSTRUCTIONS ON GLUING WINDSCREEN .

Position and width of adhesive bead: 

• Overlapping and closed
• Not visible from outside and inside
• The contact point becomes noticeable through an increase in the adhesive volume (approx. 1.5 - 2 x bead width after crushing).

  Position adhesive bead only where the glass ceramic material offers a sufficient overlap and the body flange offers sufficient space.

• The adhesive bead is not permitted in the window radii and in the cowl panel area
• Spread adhesive bead with special tool 00 9 322
  IMPORTANT: The position of the rear window may not be changed after 5 minutes from the start of adhesive application as adhesive curing is already too far advanced.
  The window may become detached if this period of time is not maintained.
  Window cementing not OK = renewed window cementing necessary.
