Upper front light clusters

UPPER FRONT LIGHT CLUSTERS

The front light clusters are specific: they differ from those of left-hand drive versions due to the different asymmetry of the low beam deflector.

The removing and refitting procedure is the same as for versions with left-hand drive (see GROUP 55, base manual), while it is necessary to pay attention to the aiming procedure given below.

N.B. In the event of replacement make sure a "right-hand drive" headlamp is used.

HEADLAMP AIMING

The upper light clusters have two possibilities of adjustment.

1. Screw for horizontal adjustment.
2. Ringnut for vertical adjustment.

Before proceeding with headlamp aiming, make sure that the lighting units mate perfectly with the bonnet in the closed position. If necessary, adjust on the slotted fasteners of the light clusters.

Vehicle preparation

The vehicle must be complete with spare wheel, tools, fuel reserve and fluids, the tyres should be at normal operating pressure with the driver on board.

Set the vehicle on a level surface with the light cluster glass 10 m from a screen or opaque surface on which the following lines have been traced:

V-V: vertical corresponding to the line of the plane of symmetry of the vehicle,

C-C: corresponding to the lines of the vertical planes passing through the reference centres of the light clusters.

HC-HC: horizontal corresponding to the height from the ground of the light cluster reference centres.

AC-AC: horizontal 14 cm below line HC - HC (for new cars), (11 cm for settled cars).

Aim the light clusters on the low beam. Working on the headlamp aiming device, proceed as follows.

NOTE: For cars fitted with headlamp aiming device, adjust with the corrector in position "0".

Vertical aiming

Make the horizontal section of the demarcation line between the dark zone and the zone lit by the beam coincide with line AC - AC on the screen.

Horizontal aiming

Make the crossing point of the horizontal and sloped demarcation lines coincide with the respective crossing point of lines C-C and AC-AC of the screen.

When needing to place the screen at a lower distance, this value must be reduced proportionately (e.g.: for a screen at half the distance, it must be halved).
