Hub
Components:
1 Hub
2 A l t e r n a t o r r o t o r
3 Fan
4 Bolt
The hub holds the alternator rotor and the cooling fan.
Unscrew the bolt clockwise and tighten at 160 Nm when refitting.
Disassembly / Reassembly
Internal alternator
Remove stator and place it inside the rotor to prevent metal particles from
being attracted by the magnets.
When refitting tighten rotor screws and stator bolts at 10 Nm.
 See page 67 ÷ 69 for alternator characteristics.
Cooling fan
Carefully clean and check all blades and inserts. Replace the fan even if
there is only a single damaged blade or only a single released insert.
 See page 16 for cooling air flow.
Tighten the fan's fixing screws at a torque of 10 Nm.
Pulley guard - Shroud - Side plates
Components:
1 Pulley guard
2 Shroud
3 Side plates
The pulley guard is made of sound deadening material: it reduces
the noise that both the pulley and the fan tend to amplify.
Shroud and side plates are made of ANTIFON, an elastic Iayer which
absorbs the noise caused by the plate vibrations.
