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.
