Overview for rear window cementing (E93)
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 322IMPORTANT: 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.
