EMUONTING
Remount :
- the end bearing and the stator;
- the front bearing;
- the attachment screws;
- the pulley wedge;
- the fan and the pulley;
- the snap ring and the pulley fixing nut;
- the brushes support;
- the voltage regulator ( for alternator type 1180 ).
Check the alternator on the bench.
Mount the alternator on the vehicle.
Connect the battery.
NOTE:
Tightening moment: - for the pulley nut 3 – 3,5 daNm ( for type 1114.200) or 7 daNm
( for type 1180 );
- terminal ( B + ) : 0.3 da Nm.
The belt shall be tighten to obtain a maximum arrow of 7,5 mm for a pushing force
of about 3 daNm,at half distance between the water pump pulley and the alternator
pulley. Exaggerate tensioning of the belt may lead to the premature wear of the both
alternator bearings and water pump bearings.
For additional informations ,please see Chapt. 07.

ALTERNATOR BEARINGS REPLACEMENT
Dismount the alternator from the vehicle.
A. FRONT BEARING REPLACEMENT
Dismount : pulley, washers and Grower washer, fan, pulley wedge and the drive shield.
Place the drive shield in a horizontal position and unscrew the three attachment screws
of the bearing cap and take out the bearing.
Mount the new bearing in the drive shield and
fix the bearing cap by means of the three screws.
Perform in reverse order the dismounting
operations of the alternator.
B. REAR BEARING REPLACEMENT
Dismount: pulley, washers and Grower
washer, fan, pulley wedge, brushes support
and front bearing – rotor assembly.
Extract the bearing by means of the
CV 28 A extractor provided with CV 48
clamps and RO 15.01 protector.

Place the protector RO 15.01 on the
rotor shaft end.
Mount the new bearing by means of a
press and using a tube, which shall rest
only on the inner ring of the bearing.
Assembly the alternator and then
mount it on the vehicle.
Mount the belt and adjust its tightening.
Connect the battery.
ALTERNATOR BRUSHES REPLACEMENT
D
ISMO UNTING
Disconnect the battery.
Unscrew the attachment screws of the
brushes support.
Dismount the used brushes off the support.
R
EMOUNTING
Mount the new brushes in their support.
Check: the sliding of the brushes in their
support, the insulation between brushes,
the continuity from the brushes contact
point with the collector up to the contacts
with chassis ground and excitation.
Mount the brushes support on the
alternator.
Connect the battery.

ALTERNATOR DIODE SUPPORT REPLACEMENT
D
ISMO UNTING
Dismount the plastic protection cap and the condenser.
Disconnect the terminals: mark the position of the wires so that may be reconected in
the same place.
Unscrew the attachment nuts;dismount the diode support.
R
EMO UNTING
Mount the diode support ; tighten the
attachment nuts.
Connect the terminals ; observe the marking
made upon disconnecting.
Mount the protection cap and the condenser.
Check on the bench the alternator.
DIODE REPLACEMENTS
The diodes having a diode support type housing made of two parts are not replaceable.
A burnt diode decreases the current intensity by about % A.
D
ISMO UNTING
Dismount the diode support off the alternator.
Check diodes by means of a control lamp connected to a 12 V direct current source.
Connect the control lamp in one sense than
reverse the polarity.
The lamp should light on when connected
to one single sense.
If the lamp lights or does not light in both
senses the respective diode is defective and
is to be replaced.
Depress the defective diode and take it out.
