77-430 Adjusting Glass Roof
NOTE:
- Glass roofs offered as special equipment must be adapted to the body when first installed.
- This adjustment work must be performed in the following sequence.
- Under certain circumstances the position of the side windows and receptacles for the pins on the B-pillar must be changed. This means that it is necessary to check the adjustment of the soft top and correct, if necessary.
- For customers who already have a hard top, we do not recommend alternate use of the glass roof and hard top for this reason.
Special Tools:
A. Adjusting gap between glass roof and windshield trim strip
1 Check gap A with special tool 129 589 03 21 00.
NOTE: Check gap in area of locking pins.
Attention: Do not damage gasket.
Gap dimensions a: 5-6 mm
b. Windshield trim strip
c. Glass roof rail
Attention: The gap should not be smaller than 5 mm, because otherwise the closing forces at the front locks would be too high. If locking and unlocking is negatively effected by exceptionally high closing forces, spacer plates can be installed below the locking pins.
Adjustment
2 Unlock glass roof, lift at front and support (e.g. with rubber hammer).
3 Mark position of locking pins with felt tip pen.
4 Loosen screws and adjust gap by moving locking pins toward rear (to reduce gap) or toward front (to increase gap).
5 Tighten screws.
6 Lock glass roof.
7 Check transition between A-pillar and corner of glass roof, correct, if necessary, by moving locking pins to side.
NOTE: If adjustment of the locking pins is not sufficient, the transition can be improved by slightly correcting the gasket on the A-pillar or the rail on the glass roof.
B. Adjusting gap between glass roof and body
8 Check gap b in relation to body with special tool 129 589 03 21 00.
NOTE: Check gap at center of C-pillar.

c. Glass roof C-pillar
d. Rear fender

13 Loosen screws and move locking pins to adjust so that they enter in the center of the locking funnel.
