Disassembly
1. Open the terminal box cover (9) and disconnect the
cables from the voltage regulator and exciter;
2. Remove the clamp and spiral to loosen the cables of
the main stator and exciter;
3. Loosen the screws that fix the exciter cover (24) and
remove it;
4. Loosen the screws that fix the rotor cables (21) and
the screws (22) that fix bush (29) and remove the
bush along with the diodes;
5. Loosen the screws (25) that fix the ND-endshield (11)
and remove it along with the exciter stator (12) using
a rubber hammer;
6. Loosen the screws (2) that fix the flange (1) and
remove it.
7. Loosen the screws (3) that fix the DE bearing cap
(26);
8. Remove the protection grille (20);
9. Loosen the screws that fix the D-endshield (4) remove
it using a rubber hammer;
10. The removal of the whole rotor must be done by the

Assembly
1. Check if machined parts of the frame, flange,
endshields and exciter cover are clean and with
corrosion protection;
2. Insert the main rotor at the alternator front side, using
appropriate device;
3. Fit the bearing seat of the ND-endshield (11) on the
rear bearing and fit it in the frame, fixing it with the
screws (25);
4. Check if the o'ring (14) is correctly placed in the
bearing seat of the ND-endshield;
5. Insert the bush (29) along with the diodes, fixing it on
shaft with the screws (22);
6. Fix the rotor cables in the screws (21) of the diode
wheel;
7. Make the cable connections of the voltage regulator
and exciter according to the alternator wiring diagram
and the voltage regulator manual;
8. Fix the cables connecting the main stator and exciter
with clamps and spiral;
9. Fit the D-endshield (4) and fix it with the screws;
10. Fix the DE bearing cap (26) with the screws (3);
11. Fit the exciter cover (16) and fix it with the screws
(24);
12. Install the protection grille (20);
13. Fit the flange (1) on D-endshield and fix it with the
screws (2);
