Changing the headlight bulbs
Before replacing a burnt out light bulb, ensure that the replacement bulb has the same voltage and power rating as specified for the lighting device in question (sect. 3 - 1.1, Lights/instrument panel).
Warning
The halogen light bulbs in the headlight become hot when switched on and remain hot for some time after they are switched off. Allow bulbs to cool before replacing them.
The position of the light bulbs in the headlight is as indicated below: low beam (lo), high beam (hi) and parking light (a).

Remove the headlight, as described in the paragraph "renewal of the headlight" of this section.
To access the headlight bulbs loosen the screws (1) and remove the cover (2).

High beam (hi)
Disconnect the wiring connector (3) from the headlight bulb (4).
Release the retaining clip (5).
The bulb (4) has a bayonet base: press and twist counter clockwise to remove.
Fit the new bulb (4), insert the tabs on the bulb base into the corresponding slots to ensure the bulb is correctly positioned, push the bulb in and turn clockwise until it clicks into place.

Refit the connector (3) to the lamp (4), the cover (2) to the headlight, then tighten the screws (1).

Low beam (lo)
To change the lo beam headlight bulb (6) see the procedure described above for the hi beam headlight bulb.

Replace the lamp with a new one of the same type and rating (sect. 3 - 1.1, Lights/instrument panel).
Note
Do not touch the transparent part of the bulb with your fingers, this will darken it and cause a loss of brightness.
Renewal of the headlight
Headlight aimRefitting the timing gears
Before reassembling the removed parts, check timing gears (13) for wear.
Change, if necessary.
Important
The timing gears (13) must always be renewed as a pair.
Refitting is the reverse of removal.
Warning
When introducing the driven gear (b) check that the tongue (15) is

Description of the clutch assembly
The clutch is disengaged by a drive unit consisting of a thrust piston (c)
accommodated inside a small cap mounted to
the generator cover. This piston (c) pushes a pushrod (b), which runs through
gearbox primary shaft and operates the Pressure plate (4)
located on top of the clutch plate pack ...
Refitting the cylinder/piston assembly
If new units are used, it is necessary to couple the cylinders and pistons of
the same selection (see paragraph "overhaul Of the cylinder
barrel/piston components" of this section).
If the pistons have been separated from their cylinders, before reassembling
these components, position the p ...
