Removing and installing headlight mounting

Tools







Technical values







Preliminary work
1. Remove main headlight.
2. Remove front apron.

Removing headlight mounting







NOTE:
Fastening screw for main headlight mounting loose
- The main headlight shakes
- Rattling noises in the body front section

- Replace fastening screws for the main headlight mounting following removal.
- Exception: To set the gap dimensions, loosen the new fastening screws and then re-tighten them to the specified tightening torque within 24 hours.

INFORMATION:
- The fastening screws have a hexagon at the top and can therefore be unscrewed from the front.







- It is therefore important to turn the screws in the opposite direction when screwing the rear fastening screws in and out.







1. Unscrew the fastening screws at the back -1- using an adjusting wrench 9717 -a- ( -arrows- ).
2. Unscrew the fastening screws -2- at the front.







3. Pull out the headlight mounting in an upward direction from the front guide rail -arrows A- and remove it to the front -arrow B-.
