Disassembly / Reassembly
Blower belt alternator - Reassembly
The half-pulley fastening nuts must be tightened using the torque
wrench to a final torque of 10 Nm.
Again during this phase the nut must be in position A when
tightened as in fig. 7 – page 22.
Blower assembly
Danger – Attention
Before demounting the cooling fan, disconnect the positive
battery cable to prevent accidental short-circuits which could
consequently energize the starter motor.
The plate and tension regulator are fixed to the outside of the blower
fan stator.
A 14 A or 21 A alternator is housed inside the stator.
See page 60 - 61 for the alternator technical data.
See page 13 for the cooling air volume.
Air shroud and baffles - Disassembly
The air shroud 1 and the baffles 2, 3, 4, 5 are shaped in such a way
as to direct the flow of air onto the cylinders in order to cool them.
As the shroud is completely covered in noise-absorbent material, it
also has the function of reducing the amount of noise generated by
the blower fan and vibrations.
Tension check
A 4 Kg load located halfway between the pulleys should cause the
belt to bend 5 ÷ 15 mm.
The correct belt tension can also be checked with special tools that
are available on sale.
